Piper PA-23-250 was on a visual flight rules training flight from the Montréal/St-Hubert, QC (CYHU) airport with a pilot in training and an instructor on board. As the aircraft was approaching to land on Runway 24R, the left engine began vibrating. The instructor noticed major power variations and decided to cut the left engine as a precautionary measure. An emergency was declared when the aircraft was 3 NM from the threshold of Runway 24R. The aircraft landed without incident and emergency services were called off.

TSB Report #A21Q0047: A Les Hélicoptères Canadiens Airbus AS355N helicopter (C-FXIH) was on a visual flight rules flight from Sept-îles, QC (CYZV) to the IOC helipad at approximately 4 NM south-west. Shortly after take-off, the red “REG” warning light lit up and extinguished at the same time as the Ng fluctuations (engine gas generator) appeared. An intermittent aural warning sounded, indicating rotor revolution overspeed (RPM); however, the pilot noticed that the RPM were in the normal functional range. Following this, the “ENG P” and “R/H GEN” warning lights lit up and the “delta Ng” indicator of engine number 2 squawked zero. The pilot followed procedures for continuing the flight with only one functioning engine. The aircraft turned back and landed without issue on Taxiway Bravo at CYZV. Maintenance crew found that the digital engine control unit (DECU) had reacted to a faulty overspeed warning and had cut the fuel feed on engine number 2.

A Sky Jet MG Inc. Beech 200 (C-GCLQ/LSJ447) from Quebec/Jean Lesage, QC (CYQB) to Chibougamau/Chapais, QC (CYMT) declared an emergency due to an indication of a fire in the left engine.

UPDATE: TSB Report #A21Q0037: A MAG Aerospace Canada Aero Commander 500B (C-GJMA) was on an instrument flight rules flight from Greenstone Regional, ON (CYGQ) to Maniwaki, QC (CYMW), with 2 crew members on board. While the aircraft was in cruising flight, about 60 NM west of Val-d’Or, QC (CYVO), the crew observed a drop in oil pressure from the left engine (IO-540-E1A5) indicator. The crew then requested to be rerouted to CYVO. On approach, the oil pressure continued to drop and the “Low Oil Pressure” indicator lit up. The crew shut off the engine as a precautionary measure. The aircraft landed without incident at CYVO. No injuries. On the ground, inspection showed that the left engine’s magneto had loosened and had caused an engine oil leak. No other damage or faults were detected.

Several aircraft reported an emergency locator transmitter (ELT) signal, between 1444Z and 1446Z, near Les Escoumins, QC. During the call to the Joint Rescue Coordination Center (JRCC) Halifax, the JRCC advised that a Heli/Express Inc. Aerospatiale AS 350 B-2 (C-GHEX) had crashed. Emergency services had not been deployed. No injuries. No service provided by NAV CANADA. No impact on operations.
UPDATE: TSB Report #A21Q0024: C-GHEX, an Aerospatiale AS350 B2 helicopter operated by Heli-Express Inc., was on a slinging flight along a high voltage line 1.7NM north of Les Escoumins, QC. The tail rotor gearbox and tail rotor separated from the helicopter while in flight. The pilot released the sling load and proceeded to a dirt runway not far from their position for an emergency landing. During the approach, there was a deceleration and the helicopter began to turn on itself towards the left. The pilot was unable to regain control of the helicopter and decided to cut off the fuel supply to stop the rotational movement and attempt a landing without an engine. The aircraft struck the ground hard in an upright position, without tipping over to the side. The emergency locator transmitter was activated. A second helicopter touched down shortly thereafter with rescuers and the injured pilot was transported to hospital.

A Propair Inc. Beech A100 (C-GJJF/PRO4320) from Rouyn-Noranda, QC (CYUY) to Montreal/Pierre Elliott Trudeau, QC (CYUL) declared an emergency due to the loss of an engine. PRO4320 landed safely at 0528Z.
UPDATE: TSB Report #A21Q0017: C-GJJF, a Beechcraft BE10 operated by Propair under the callsign PRO4320, was on an instrument flight rules flight from Rouyn-Noranda, QC (CYUY) to Montreal/Pierre Elliott Trudeau, QC (CYUL). While the aircraft was in cruising flight, about 30 minutes from CYUL, the parameters of one of the 2 engines (Pratt & Whitney PT6A-28) began to give erratic indications. The crew shut down the engine as a precaution, and declared an emergency (PAN PAN). The aircraft landed safely at CYUL. Maintenance replaced an FCU and the aircraft was returned to service.

At 1132Z, a Dynamitage Castonguay Piper PA-31 (C-GLAZ) on a flight from Montreal/St-Hubert, QC (CYHU) informed the air traffic controller (ATC) of an engine problem and requested to be rerouted to Montreal/St-Hubert, QC (CYHU). At 1136Z, C-GLAZ declared an emergency and informed ATC that it was descending to land at La Macaza/Mont-Tremblant, QC (CYFJ). The aircraft landed safely at 1152Z. No impact on operations.
UPDATE: TSB Report #A21Q0021: C-GLAZ, a privately operated Piper PA-31, was on an instrument flight rules flight from Val dOr, QC (CYVO) to Sherbrooke, QC (CYSC) with a pilot and 3 passengers on board. After approximately 40 minutes of flight at a cruising altitude of 9,000 feet ASL, the pilot noticed a drizzle of oil on the right engine cover. The engine oil pressure reading was normal. As a precaution, the pilot requested ATC authorization to divert to Montreal/St-Hubert, QC (CYHU) and climb to an altitude of 11,000 feet. Shortly thereafter, one of the passengers informed the pilot that they saw a significant accumulation of oil on the right wing flap of the aircraft. The engine oil pressure gauge read lower. The pilot decided to shut down the right engine as a precaution. Given the aircrafts proximity to La Macaza/Mont-Tremblant, QC (CYFJ), the pilot advised ATC of the situation and of their intention to land at CYFJ by performing a visual approach. The aircraft touched down safely on Runway 21.

At Quebec/Jean Lesage, QC (CYQB), an emergency locator transmitter (ELT) was operating on board an aircraft that was undergoing maintenance. The Joint Rescue Coordination Centre (JRCC) Trenton was already aware. The aircraft was located and the ELT was shut off at 1813Z.

UPDATE: Aviation Incident Report: A privately registered R44 helicopter, on a local flight from Chicoutimi/St-Honoré, QC (CYRC), crashed near Saint-Henri de Taillon, QC, in the vicinity of Lac Saint-Jean. There were 2 souls on board who sustained minor injuries. Emergency crews arrived on the scene and the Transportation Safety Board of Canada (TSB) has been notified.
UPDATE: TSB Report #A21Q0006: A privately registered Robinson R44 helicopter, was on a visual flight rules flight to and from Chicoutimi/St-Honore, QC (CYRC) airport with a pilot and one passenger on board. The pilot was hovering about 20 or 30 feet from the ground in front of a chalet located on the shores of Lac St-Jean, in the Saint-Henri-de-Taillon sector. As the pilot turned to the right, the helicopter lost altitude. The pilot attempted to sustain the aircraft at the lower altitude, but had to land the helicopter in the snow. The left skid sank and the helicopter flipped over. When the aircraft came to a stop, the pilot shut down the engine, which was still running. The pilot and passenger evacuated and sustained minor injuries. The helicopter sustained significant damage. The emergency locator transmitter (ELT) did not activate.

A 9519 Investments Ltd. Cessna 560 Citation Ultra (C-GHCW) from Prince George, BC (CYXS) to Vancouver, BC (CYVR) departed and, on initial contact with the Vancouver (VR) area control centre (ACC), reported a mechanical issue and requested to return to CYXS. C-GHCW was vectored for the approach and landed safely. No operational impact.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. After takeoff, one engine became unresponsive. An indication of N1 overspeed occurred, so the throttle was moved about 3 inches, with no response. Then, an N2 overspeed indication occurred, so the engine was shut down. The fuel control unit is being replaced for troubleshooting.

A Kalitta Charters II Boeing 747-400 (CKS652) from Anchorage, AK (PANC) to Miami Intl, FL (KMIA) reported a fuel issue and they turned off #1 engine, leaving them operating with 3 engines.

During a stop-and-go on Runway 19 at Abbotsford, BC (CYXX), a Skyquest Aviation Ltd. Piper PA-34-200 (C-GTYH) from Langley, BC (CYNJ) to Langley, BC (CYNJ) advised the tower that it had a flat tire. Runway 19 was temporarily shut down. Minimum impact to operations.

A Seair Seaplanes Ltd. Cessna 208 (C-GIGO), while being pushed from the dock, started its engines. The deckhand lost control while holding the rope, resulting in contact with a Harbour Air Ltd. de Havilland DHC-3 (C-GUTW), which was docked adjacent. Significant damage to both aircraft.
UPDATE: TSB Report #A21P0058: C-GIGO, a float equipped Cessna 208 aircraft operated by Seair Seaplanes Ltd., was preparing to conduct a flight from Ganges Harbour, BC (CAX6) to Vancouver, BC (CYVR) with 1 crew member on board. Prior to the engine starting, the dockhand assisting the pilot untied the guide rope and held it in their hand. When the engine started, the aircraft travelled forward, pulling the rope from the dockhand. The aircraft began travelling forward until the propeller of C-GIGO struck the rear of C-GUTW, a float equipped DHC-3T operated by Harbour Air. After the initial prop strike, the pilot of C-GIGO quickly shut down the engine, as the aircraft rotated 90 degrees, striking C-GUTW with the right-hand (RH) wing. C-GUTW was tied to the dock with no one on board during the occurrence. There were no injuries; both aircraft sustained substantial damage.

At Campbell River, BC (CYBL), a Sealand Flight Ltd. Cessna 172I (C-GCYR) accidentally activated its emergency locator transmitter (ELT) at 2115Z. The ELT was shut off at 2117Z.

A JimJet Resources Inc. Cessna 414A (C-FZAM) from Abbotsford, BC (CYXX) to Calgary/Springbank, AB (CYBW) declared an emergency due to mechanical trouble. C-FZAM shut down one engine and landed at Kelowna, BC (CYLW) without incident.
UPDATE: TSB Report #A21P0037: C-FZAM, a privately operated Cessna 414A, was conducting a flight from Abbotsford, BC (CYXX) to Calgary/Springbank, AB (CYBW) with 1 pilot on board. While in cruise at 21 000 feet ASL, approximately 30NM East of Kelowna, BC (CYLW), the pilot observed a slight drop in fuel flow to the right engine, a Teledyne Continental Motors TSIO-520-NB (S/N: 504315). A short time later, the fuel flow dropped rapidly, followed by reduced engine power. The pilot completed the emergency checklist for a suspected engine driven fuel pump failure, which calls for the Auxiliary Pump set to high, and this restored fuel flow and engine power to normal. The pilot elected to divert to CYLW and conduct a precautionary landing. During the descent into CYLW, the aircraft experienced significant vibrations, with the right-hand engine power fluctuating. The pilot declared a "MAYDAY", shut down the right engine, and proceeded with a single engine approach and landing. The aircraft landed without further incident. There were no injuries. Subsequent maintenance actions revealed the right-hand engine driven fuel pump had experienced partially seized internals but the shaft was still intact, which allowed the pump to cavitate and/or continue pumping fuel, creating power fluctuations. The fuel pump was replaced and the aircraft was returned to service.

The flight service station (FSS) received a notification from the area control centre (ACC) that a Pacific Coastal Airlines Ltd. Beech 1900 (PCO866) from Port Hardy, BC (CYZT) to Vancouver, BC (CYVR) had declared a MAYDAY due to a lost engine. PCO866 landed at CYZT without incident at 0026Z.
UPDATE: TSB Report #A21P0029: C-FPCV, a Pacific Coastal Airlines Textron Beech 1900C, was conducting flight PCO866 from Port Hardy, BC (CYZT) to Vancouver, BC (CYVR) with 2 flight crew members and 9 passengers on board. When climbing through 16 000 feet ASL, the aircraft began to yaw to the right. The aircrafts RH engine, a PT6A-65B (S/N: PCE32157), was indicating a significant reduction in torque and an increased inter-stage turbine temperature (ITT). As the ITT continued to increase, a burning smell was perceived in the cockpit. The flight crew carried out a precautionary engine shutdown. The pilot that was monitoring declared an emergency (MAYDAY) and made the request to return to CYZT. The aircraft landed without further incident. Subsequent maintenance actions revealed the engines compressor turbine disk had experienced a blade failure, leading to other blades on the disk to fail. The operators maintenance has indicated that with the compressor no longer turning at an optimal speed, the engine power was reduced and was accompanied by a build up of heat. The engines abnormally hot bleed air entering the air cycle machine (ACM) likely created the burning smell. The operator has shipped the engine to the manufacturer for a comprehensive teardown.

A privately registered Mooney M20K from Langley, BC (CYNJ) to Langley, BC (CYNJ) reported a faint emergency locator transmitter (ELT) signal on the ground as it taxied in and shut down. The ELT signal could only be heard by the tower on the hand-held radio (NICAN) with the squelch on. The incident was reported to the shift manager.

A Coldstream Helicopters Ltd. Bell 407 (C-GVIH) was completing work for BC Hydro near Invermere, BC (CAA8), with a pilot and 2 passengers (PAX) on board. Upon return to CAA8 at the end of the workday, the pilot observed a remotely piloted aircraft system (RPAS) operating 50 meters from the helicopter. The RPAS was described as a large one, with a width of approximately 16 inches by 18 inches. The pilot landed the helicopter without further issues, but they confronted the RPAS operator upon landing, who was standing near the helipad. The pilot was unclear why the RPAS operator was flying the RPAS at the airport, but the pilot believes that the RPAS operator was attempting to film landing and departing aircraft. The RPAS operator did not have a radio capable of ground to air communications and was therefore unaware of aircraft operating in the area. The RPAS operator claimed to be a licensed operator, and they gave the helicopter pilot their contact information. The 2 BC Hydro employees in the back have filed reports with BC Hydro (their employer), as all 3 persons onboard the helicopter were "rattled" by the occurrence. A Transportation Safety Board of Canada (TSB) investigator discussed the situation with the "defacto" airport operator, and the airport operator was not informed of any RPAS activity happening at the airport that day.
UPDATE: Aviation Incident Report #16995: The operator of a DJI Inspire 2 drone was operating at Invermere, BC (CAA8). The operator was flying the drone approximately 5 to 8 meters above ground level (AGL) while filming the pilot of a Cessna 177 and 2 passengers pushing the aircraft. The operator was in direct communications with the pilot of the Cessna 177 as they were only 20 meters apart. The drone had just commenced when a Coldstream Helicopters Ltd. Bell 407 (C-GVIH) on a flight to Invermere, BC (CAA8) arrived on short final. The drone operator did not have communication with C-GVIH. The drone operator brought their drone back toward the take-off area, which was just beside the hangar, while always maintaining sight with C-GVIH and keeping the drone at a low level. C-GVIH landed without incident and shut down. The drone operator moved the drone further from the hangar area, but continued to hover at a low level. The drone operator landed shortly after C-GVIHs flight operations had ended. C-GVIH and the drone operator communicated about the failure in communications and radio protocol.

An Okanagan Aviation Academy Inc. Piper PA-30 (C-FCCM) from Kelowna, BC (CYLW) to Kelowna, BC (CYLW) experienced an engine stall while conducting a touch-and-go. The aircraft exited the runway at Taxiway B. No operational impact.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. A Piper PA-30 aircraft (C-FCCM) experienced an engine stall/shut down on a planned touch-and-go. The chief flight instructor reported that the student went to full idle too quickly and firmly moved the throttles past the "idle" detent to the "throttle cut-off" position on the left throttle. Moving past the throttle cut-off position is used when an engine "diesels" during shut down, in order to cut off the engine when mixture alone does not shut down the engine. The student was debriefed and the issue will be reviewed with the instructors to ensure it is covered with future students.

A Central Mountain Air Ltd. Dornier 328-100 (C-FDYN/GLR8438) from Kelowna, BC (CYLW) to Prince George, BC (CYXS) declared PAN PAN due to an oil indication. The aircraft continued to its destination, where it landed without incident at 1730Z. No operational impact. (Information from Aviation Incident Report (AIRA) incorporated into narrative summary)
UPDATE: TSB Report #A21P0009: C-FDYN, a Central Mountain Air Dornier DO-328 aircraft, was conducting flight GLR8438 from Kelowna, BC (CYLW) to Prince George, BC (CYXS) with 3 crew members and 11 passengers on board. During cruise flight at FL240, the flight crew noticed indications of oil pressure fluctuations on the right engine (Pratt & Whitney Canada PW119B). ATC advised the flight crew that the flight would be required to hold prior to commencing the approach at CYXS due to traffic. The flight crew declared a PAN PAN and landed as soon as practical, without further incident. Subsequent maintenance actions revealed the engines no. 3 and no. 4 bearing labyrinth seals were leaking air and pressurizing the bearing cavity, to the point where oil had been pushed out into the intercompressor turbine case and overboard, into both the cowling and the exhaust burn-off ducts. The operator has coordinated with the engine manufacturer and has indicated that the engine requires replacement.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. It was noted that the oil level was a little low upon the aircrafts landing in Prince George, BC (CYXS). There was also some oil present in the cowling, suggesting a potential leak at first evaluation. The oil was cleaned up and ground runs were performed, and the oil fluctuations did not reappear. The oil pressure and temperature were steady at all power settings. After shut down, it was noticed that oil was dripping from the cowling collector drain ports, but there was no evidence of further leaks. Oil dripping from the drains is not uncommon, after noting previous oil in the cowling area, as this is the common dump point for all scavenge or ported oil. Oil levels were still maintained at required levels. The aircraft was ground run for another 30 minutes, with no fluctuation in oil pressure. The aircraft was ferried back to Calgary, empty, for further analysis. Analysis result from Calgary, after multiple runs and tests, is currently pointing towards the internal #3 or #4 bearing labyrinth seal leaking air, and thus pressurizing the bearing cavity to the point of pushing oil out into the inter-compressor turbine case and overboard, into both the cowling and the exhaust burn-off duct. This is an internal fault of the engine that, although is not typical, is something that has been present in many turbo-prop engines in the past. Pratt & Whitney have been notified of all the tests and runs, and agree that the inner bearing seal has most likely failed and will require the replacement of the engine.

A Jazz de Havilland DHC-8-402 (C-GJZG/JZA8256) from Nanaimo, BC (CYCD) to Vancouver, BC (CYVR) reported smoke in the cockpit and evacuated the aircraft. The aircraft was still at the terminal. No operational impact.
Aviation Incident Report: At approximately 1735Z, on January 25, 2021, the captain of a Jazz de Havilland DHC-8-402 (C-GJZG/JZA8256) from Nanaimo, BC (CYCD) to Vancouver, BC (CYVR) declared an emergency due to smoke in the flight deck and cabin and initiated a rapid deplanement of passengers through the front and back doors. The aircraft was being de-iced at the gate in CYCD in preparation for departure to CYVR when smoke fumes entered the flight deck and cabin via the auxiliary power unit (APU). Emergency crews responded.
UPDATE: TSB Report #A21P0004: C-GJZG, a Jazz de Havilland DHC-8-402, was scheduled for a flight from Nanaimo, BC (CYCD) to Vancouver, BC (CYVR) with 4 crew and 47 passengers onboard. During de-ice operations at the gate, the auxiliary power unit (APU) ingested de-ice glycol, causing smoke and fumes to enter both the cockpit and the cabin. The captain shut down the aircraft and ordered an evacuation over the public announcement system. The cabin crew directed passengers through the front left main cabin door and both aft exits boarding stairs were moved to the aft left exit part way through the evacuation. The ground crew observed the deplaning and ceased de-ice operations at the right wing. Emergency crews responded, but were not required. There was 1 minor injury reported by a passenger to the Nanaimo Airport Commission. Maintenance confirmed the smoke and fumes were from de-ice glycol entering the aircraft through the APU bleed system. The APU was ground run to purge all glycol from the system and the aircraft was returned to service.

The nose wheel of a Pacific Rim Aviation Academy Inc. Diamond DA 20-C1 (C-GDDP) from Pitt Meadows, BC (CYPK) to Pitt Meadows, BC (CYPK) fell off during a touch-and-go. Air traffic control (ATC) noticed and advised the pilot. The aircraft circled until emergency vehicles were at the airport and then landed on Runway 26L. All occupants exited the aircraft safely, but the aircraft was disabled on the runway. Other traffic was moved to Runway 26R.
UPDATE: TSB Report #A21P0002: C-GDDP, a Pacific Rim Aviation Academy Diamond DA 20-C1, was conducting circuit training at Pitt Meadows, BC (CYPK) with 1 instructor and 1 student onboard. The lesson was focused on short-field take-offs and soft field landings. During the 5th circuit, the crew observed a small vibration upon touchdown, however, the vibration was minimal due to the back pressure on the flight controls as part of the soft field landing procedure. Once flaps were selected to take-off, the vibration increased slightly and then the aircraft became airborne. On the cross-wind leg, the CYPK tower advised the pilot that the aircraft may have lost the nose wheel. The pilot conducted a "low and over" while the tower confirmed that the nose wheel had departed the aircraft. The aircraft was put into an orbit above CYPK while emergency crews were assembled on the ground and checklists were completed in the aircraft. Approximately 25 minutes later, the aircraft landed. During the landing, the aircraft was operated at a reduced airspeed, with the fuel and magnetos shut off. The front nose gear strut broke off the aircraft and the aircraft slid to a stop on the front lower engine cowl. There were no injuries and no fire.

A Voyageur Airways Bombardier CL-600-2B19 (C-GIXT/VAL200) from North Bay, ON (CYYB) to Muskoka, ON (CYQA) declared "PAN PAN" with no. 2 engine shutdown, and requested a return to CYYB. VAL200 landed at CYYB at 1704Z, without further incident (WOFI). The Aircraft Rescue and Fire Fighting (ARFF) unit attended the aircraft on the runway. After ARFF inspection, the aircraft taxied to the ramp under its own power. No impact to operations.

Aviation Incident Report #17212: A privately registered Cessna 172E from Kincardine, ON (CYKM) to Hanover/Saugeen, ON (CYHS) landed Runway 19 and made a radio call advising they were clear of the runway on Taxiway Bravo. The aircraft was taxiing north on Bravo toward the north hangars when an Airport Managers vehicle (Chevrolet Trailblazer) departed the terminal and arrived near the end of the taxiway. It was left unattended, parked on the taxiway, and blocking the aircraft. The aircraft manoeuvred off of Taxiway Bravo in order to continue to the airport. After the aircraft was shut down, the Airport Manager returned to their vehicle and departed down the taxiway.

Aviation Incident Report #17190: While on approach, a privately registered Beech 36 on a flight to Killarney, ON (CPT2) used the callsign "Bonanza" for the entirety of operations within the airspace. Upon calling the aircraft and requesting its registration, the aircraft obliged; however, it went back to using only "Bonanza" as its callsign until it shut down on the apron at CPT2.
UPDATE: Aviation Incident Report #17189: A privately registered Beech 36 on a flight to Killarney, ON (CPT2) landed, taxied to the apron, and parked backwards (relative to tie-downs and other aircraft). After the aircraft was shut down, the ground crew advised the pilot to grab the tow bar and help turn the aircraft around. The pilot became unruly and demanded an explanation as they wanted to park in that position due to light winds. The ground crew advised that the pilot could park in the direction they were facing if they pushed the aircraft over to the other side of the apron. The pilot responded with a profanity.

Aviation Incident Report #17106: At Parry Sound, ON (CNK4), a 2341224 Ontario Inc. Cessna 340A (C-GZSN) was parked at the fuel tanks for refuelling and asked the Airport Fueler to use 100 LL. The aircraft has placards next to the fuel caps indicating "AVGAS/100 LL only". The aircraft later lined up for departure Runway 35 on a flight from Parry Sound, ON (CNK4) to Toronto/Buttonville, ON (CYKZ). Upon rotation, at maximum power for takeoff, both engines began to surge and run erratically. The pilot tried adjusting the power settings to reduce the surge, but was unsuccessful. The pilot scanned the engine instruments and noticed excessively high cylinder head temperature (CHT) on both engines. They executed a teardrop 180-degree turn and made an emergency landing on Runway 17, taxied to the main apron, and shut down the aircraft. The aircraft had been filled with JET-A. The aircraft has been grounded at CNK4 for a maintenance inspection and approval to ferry it back to CYKZ for additional maintenance.

Aviation Incident Report #17068: At Wingham/Richard W. LeVan, ON (CPR7), it was reported that the fuel pumps were shut off without an update to the Canada Flight Supplement (CFS) and NOTAMs concerning model jets were not issued. Additionally, lighting and the global positioning system (GPS) approach require maintenance.

A Chartright Air Inc. Canadair CL600-2A12 (C-GPAJ/HRT056) from West Palm Beach, FL (KPBI) to Toronto/Lester B. Pearson, ON (CYYZ) declared a "PAN PAN" on the downwind for Runway 24L and advised shutting down its left engine. HRT056 landed on Runway 24L at 0016Z without further incident. No operational impact.

TSB Report #A21C0070: C-FNIJ, an ATR 72-212A aircraft operated by North Star Air Ltd., was conducting flight BF104 from Kashechewan, ON (CZKE) to Pickle Lake, ON (CYPL). At approximately 130 miles east of CYPL, the flight crew heard a noise and observed the left "Chip Detector" warning light illuminate. They then actioned the QRHs "Engine Fail" in-flight checklist and shut down the engine (Pratt and Whitney-Canada PW127F), as per SOPs. The flight crew declared an emergency and continued to CYPL, where they carried out an uneventful landing. The aircraft was shut down on the runway and maintenance towed the aircraft to the apron. During a subsequent maintenance inspection, the left AGB chip detector was removed and oil was drained. Metal particles were observed on the chip detector and in the oil. The left engine (S/N PCE-PY0070) was removed and sent for repair.

A privately registered Cirrus SR22 from Timmins/Victor M. Power, ON (CYTS) to Brantford, ON (CYFD) received a pre-taxi clearance and departure validation for Runway 28. The aircraft aborted its takeoff due to an engine issue, and then returned to the main apron for high power engine tests and shut down. The aircraft departed Runway 28 at 1525Z without issue.

TSB Report #A21O0049: On June 26, 2021, a Thunder Airlines Mitsubishi MU-2, operating as THU890, was conducting a flight from Toronto/Buttonville, ON (CYKZ) to Thunder Bay, ON (CYQT).
