A North Cariboo Flying Service Ltd. British Aerospace Avro 146 Series RJ100 (C-FSUA/NCB1503) from Terrace, BC (CYXT) to Calgary, AB (CYYC) rejected its take-off from Runway 15 due to an indication that a cargo door was not closed. The aircraft taxied back to the ramp to ensure that the door was closed.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The operator reported that the warning light extinguished upon rejection of the takeoff. At the ramp, the door was confirmed closed and the trip continued as scheduled, with no further issues. When the aircraft returned to base, company maintenance inspected the aircraft and found the cargo door switches to be out of Aircraft Maintenance Manual (AMM) limits. The affected switches were adjusted to AMM limits and operational checks were carried out. This intermittent door warning has occurred previously and the company is in the process of acquiring the necessary system components to replace the original parts. No further action.

At Fort St. John, BC (CYXJ), a privately registered Cessna 150H reported aborting its takeoff from Runway 30 at 1748Z, signaling power issues. The pilot then taxied the full length of Runway 30 onto Taxiway A and to the ramp, without issue.

A Southern Interior Flight Centre (1993) Ltd. Beech 76 (C-GSFB) from Kelowna, BC (CYLW) to Kelowna, BC (CYLW) requested that the Aircraft Rescue and Fire Fighting (ARFF) unit be on standby, as the aircraft had an unsafe landing gear indication with "3 green". The aircraft landed without incident. The runway was inspected immediately for foreign object debris (FOD). No operational impact.
UPDATE: TSB Report #A21P0010: C-GSFB, a Beech Duchess BE76 operated by Southern Interior Flight Centre on an IFR training flight, experienced a landing gear extension issue on approach to Kamloops, BC (CYKA). The flight crew cycled the landing gear and did not observe a "landing gear down safe" indication. The flight crew declared a "PAN PAN", elected to cancel their IFR clearance, and proceeded VFR back to Kelowna, BC (CYLW). A manual landing gear extension was performed, and a "safe landing gear down" annunciation was observed. ARFF were on standby for the eventful landing. The aircraft taxied off the runway and returned to the ramp.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. On approach into Kamloops, BC (CYKA), the landing gear of C-GSFB would not extend, so the crew decided to return to Kelowna, BC (CYLW). The crew performed an emergency landing gear extension, landed and taxied without issue. Maintenance found no obvious defects upon initial inspection. The aircraft was put on jacks and the landing gear retracted and extended normally. The landing gear hydraulic power pack level was good, and the landing gear motor brushes, the landing gear system wiring, the landing gear up/down relays, and the landing gear actuators were inspected, with no faults found. No issues were found during the landing gear physical check for stiffness, and more landing gear swings were carried out, with no faults found. The aircraft was released back into service, as no faults were found. It is suspected that the issue was temperature related, given that when the aircraft was moved from an extreme cold temperature to a warm hangar, the problem disappeared. Most likely, the landing gear motor froze or the landing gear down relay froze open. These components are not well sealed, and the operator has experienced issues with these components on other aircraft with extreme temperature changes.

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.

A Cargojet Airways Boeing 767-39H (C-FGSJ/CJT514) from Vancouver, BC (CYVR) to Hamilton, ON (CYHM) landed on Runway 30 and was instructed to execute a 180 degree turn around in order to exit at Taxiway Golf. The pilot advised that they had run out of room and were on the edge of the pavement at the grass, unable to complete the turn. The following three arrivals had to be rerouted to the area navigation (RNAV) 24 approach (wind 290 at 10G18), and all landed safely. A tow vehicle could not free CJT514 and the aircraft was advised by its operations unit to "power back". The aircraft then taxied back to the ramp on its own power 30 minutes later.

Aviation Incident Report #17234: A D.B. Air Piper PA-31-350 (C-FNAG) was observed doing a low-and-over past the Ottawa/Carp, ON (CYRP) fixed-base operator (FBO), and then began climbing into a high-speed, steep turn to the right and entered a right-downwind. From the right-downwind, the aircraft initiated a second high-speed, low altitude pass in front of the FBO from the east to west, and then climbing into another high-speed bank turn across the runway to the south where it entered the downwind for Runway 28 at a low altitude. The aircraft landed and then disembarked passengers on the FBO ramp. The Airport Manager spoke to the pilot-in-command, and they advised the aircraft was performing aerial work for a client and they made their intentions clear to CYRP traffic. There was no traffic for the duration of the flight (8 minutes).
UPDATE: Duplicate Aviation Incident Report #17257: A D.B. Air Piper PA-31-350 (C-FNAG) on a flight to Ottawa/Carp, ON (CYRP) was observed overlying the MNB Hangar at high speed and 100 feet above ground level (AGL). The aircraft circled around for Runway 28, did a high speed low-and-over, conducted an overshoot, and then turned hard to the right below 1000 feet AGL (possibly 400 feet AGL). The aircraft circled again for Runway 28, and it banked at least 60 degrees around for an approach and picked up speed. On final, and about one-third of the way down the runway (in midair), it broke off towards the apron again and overflew the fixed-base operator (FBO) and MNB Hangar at approximately 100 feet AGL. The aircraft circled back again, landed, and parked in front of the FBO. The pilot reported they made numerous radio calls and visually confirmed there was no traffic in the circuit. (Duplicate AIRA #17257 / CADORS 2021O1833 deleted after information merge)
UPDATE: Duplicate Aviation Incident Report #17284: A D.B. Air Piper PA-31-350 (C-FNAG) conducted a low-and-over manoeuvre past the fixed-base operator (FBO) terminal and then commenced a high-speed, climbing, steep turn to the right, and entered the right downwind. The aircraft then conducted a second high-speed, low altitude pass in front of the FBO terminal from east to west, and another high-speed, high bank climbing turn, across the runway to the south, where it entered the downwind for Runway 28 at a low altitude. The aircraft landed and then disembarked 5 to 6 passengers on the FBO ramp. Right-hand turns/circuits are not permitted at Ottawa/Carp, ON (CYRP). The pilot-in-command indicated that there were no other aircraft in the circuit and that they had transmitted their intentions at every stage of the flight.

TSB Report #A21O0053: A privately registered, amateur-built Cozy Mk IV was conducting a VFR flight from Carp, ON (CYRP) to Arnprior, ON (CNP3). After announcing their landing intention on 122.7 MHz, the pilot was on final for Runway 28 when they saw a truck towing a floatplane, a privately registered Cessna 172I, on the North side of the runway and proceeding to the runway from Taxiway A. As the airplane continued the final approach, the pilot noticed the truck with the airplane in tow proceeded to cross the runway and move toward the seaplane ramp access road. The Cozy Mk IV aircraft landed on Runway 28 and was still on its main landing gear when passing the floatplane on the trailer, lowering the nose shortly after. The truck towing the floatplane was not equipped with a VHF radio and the driver did not see the aircraft on final approach when they stopped at Runway 28. The truck driver saw the arriving airplane when they were already on the runway, and accelerated to clear the runway. The Cozy Mk IV aircraft completed the landing roll without further incident.
UPDATE: Aviation Incident Report #17182: A privately registered, amateur-built Cozy Mk IV from Carp, ON (CYRP) to Arnprior, ON (CNP3) was conducting an overhead approach into CNP3 from the north, with radio call over the city of Arnprior, at 1600 feet. When the aircraft was over CNP3 at 1400 feet, they made a second radio call immediately following the Skyvans radio call. They entered the mid-downwind for Runway 28 at 1400 feet and made the radio call accordingly. The aircraft lowered its landing gear and called base and then final. They saw a pickup truck towing a privately registered Cessna 172I on the right side of the runway (north) moving south toward the runway. The aircraft continued its approach and the truck did not stop at the edge of the runway. The truck continued across the runway approximately 1200 feet in front of the aircraft as it crossed the threshold of Runway 28. The aircraft moved a few feet to the right of the centreline to ensure no contact during braking. The truck continued on its route to the seaplane ramp and did not stop. The truck had no flashing light and did not stop and check for arriving/departing aircraft before crossing the runway. The truck did not make any radio calls on 122.7 MHz.
UPDATE: Aviation Incident Report #17182: Arnprior, ON (CNP3) synchronized the pilots in flight video with CNP3s 4K surveillance cameras. The vehicle pulling the trailer does come to a complete stop prior to entering the runway. The camera used in the cockpit is a wide angle lens, making things appear further away than they are. Observation: The pilot was still on their main as they passed the trailer, lowering the nose just shortly after.

TSB Report #A21C0039: C-GMWT, a de Havilland DHC-8-300 operated by Wasaya Airways under CARs Subpart 604, was enroute from Pickle Lake, ON (CYPL) to Opapimiskan Lake, ON (CKM8) with a crew of 3 and 1 passenger on board. While on approach into CKM8, the crew selected the windshield heat "ON" and heard arcing, followed by a flame and smoke coming from the first officers windshield electrical interface. The crew immediately turned the windshield heat off and the flame and smoke dissipated. The crew then landed the aircraft safely and, while taxing to the ramp, the first officers windshield cracked. The operator will advise TSB of their findings.

An Expedition Helicopters Inc. Aerospatiale AS-350-BA (C-FHAU) on a flight to Dryden, ON (CYHD) reported on final for the ramp at 0107Z. No "down" call was received. A Ministry of Natural Resources (MNR) pilot who was on the ground heard the search call and was able to make contact with the pilot in question. No impact to operations.

A Skydive Toronto Inc. Cessna 182J (C-FAXJ) reported a tow bar on the runway after landing. No other aircraft reported seeing a tow bar. Staff members at Muskoka, ON (CYQA) were advised. A privately registered Cessna 172K said theyd collect it and bring it to the ramp for staff members. A vehicle (INSP202) confirmed that it was a tow bar and it "must have come off an airplane" at 2351Z. Known impact to operations: C-FAXJ departed from Runway 18 south of the foreign object debris (FOD).

After completing multiple ramp checks, the flight service station (FSS) located the owner of a Wilderness Helicopters 2009 Ltd. Aerospatiale AS 350 B-2 (C-GYFS) from Wawa, ON (CYXZ) to Wawa, ON (CYXZ), and dispatched to the airport. The pilot called to close the flight plan at 2325Z.

A Brampton Flying Club Cessna 172S (C-GHXU) from Wiarton, ON (CYVV) to London, ON (CYXU) landed on Runway 27 and, while on Taxiway Golf, reported being unable to taxi. It was determined that the aircraft had a flat tire. The taxiway was blocked for approximately 90 minutes before aircraft could be towed off the taxiway to the ramp.

At 1755Z, a Bamaji Air Inc. Found Brothers FBA-2C1 (C-FKAC) from Sioux Lookout, ON (CYXL) to Sioux Lookout, ON (CYXL) departed from Runway 34, advised the flight service station (FSS) of an aircraft issue, and landed on Runway 16 at 1801Z. The aircraft taxied off of the runway under its own power, and shut down on Taxiway A. The airport operator (APO) conducted a foreign object debris (FOD) check, and found an oil puddle on the taxiway. Taxiway A was closed from 1816Z to 1840Z. No other impact to operations.
UPDATE: TSB Report #A21C0017: C-FKAC, a Found Brothers FBA-2C1 aircraft operated by Bamaji Air Inc., departed Runway 34 at Sioux Lookout, ON (CYXL) with only the pilot on board. During the initial climb, the pilot noticed oil seeping onto the engine cowling and windshield. The pilot elected to return to CYXL, where the aircraft landed safely and taxied off the runway. The aircraft came to a stop and the engine (Lycoming IO-540-A2B) was shut down on Taxiway A. The aircraft was then towed back to the operators ramp. An inspection by the operators maintenance personnel revealed oil leaking from the engine crankshaft seal and a frozen engine breather tube.

Aviation Incident Report: A Jazz Embraer ERJ 170-200 SU (JZA7486) from Toronto/Lester B. Pearson, ON (CYYZ) to New York/LaGuardia, NY (KLGA) reported a bird strike on final for Runway 22.

A Canadian North Boeing 737-300 (AKT1420) from Calgary, AB (CYYC) to Fort Mackay/Albian, AB (CAL4) was taxiing from Apron 4 for a departure off of Runway 29. AKT1420 had to apply the brakes while underway on Apron 4 due to an L R Helicopters Inc. Robinson R44 II (C-FLWB) from Calgary, AB (CYYC) to Calgary, AB (CYYC) also departing from the same apron and coming in close proximity to AKT1420.
UPDATE from Flight Operations: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. Air traffic control (ATC) confirmed to the pilot later that the helicopter had the clearance and that it was carried out correctly. It appears that the ATC Ground Controller did not communicate with the Departure Controller, and a Boeing 737 aircraft was cleared to taxi on Apron 4 without being advised that a helicopter was taking off from the ramp. No further action required.

A North Star Air Douglas DC3C (C-FVNS/BF105) from St. Theresa Point, MB (CYST) to Thompson, MB (CYTH) was provided a departure advisory and started backtracking on Runway 04 at 2107Z. An MHA Enterprises Ltd. Piper PA-32-300 (C-FWLE) from St. Theresa Point, MB (CYST) to Red Sucker Lake, MB (CYRS) called up at 2111Z for a departure advisory and was provided with traffic information regarding BF105 backtracking and departing. BF105 reported aborting its takeoff because C-FWLE had started entering the runway as BF105 was on the take-off roll. C-FWLE exited the runway and BF105 backtracked again and departed at 2116Z. No other operational impact.
UPDATE: TSB Report #A21C0068: C-FVNS, a Douglas DC-3C-BT-67 aircraft operated by North Star Air as flight BF105, began its takeoff on Runway 04 at St. Theresa Point, MB (CYST) with a flight crew of 2 on board. At the same time, C-FWLE, a Piper PA32 aircraft operated by MHA Enterprises Ltd., was approaching Runway 04 on the taxiway. During the takeoff roll of flight BF105, the crew noticed C-FWLE suddenly accelerate forward on the taxiway. As a precaution, the crew of flight BF105 decided to reject their takeoff. C-FWLE was able to stop before entering Runway 04 and immediately returned to the ramp. Flight BF105 then backtracked Runway 04 and departed shortly after.

At Edmonton, AB (CYEG), a Royal Canadian Mounted Police (RCMP) vehicle proceeded onto Taxiway Alfa at Oscar without authorization. A CYEG field maintenance vehicle established contact with the RCMP vehicle, who then returned to the ramp and left the field. No impact on operations.

A North Cariboo Flying Service Ltd. de Havilland DHC-8-311 (C-GAQN/NCB2047) from High Level, AB (CYOJ) to Peace River, AB (CYPE) returned to the apron after taxiing to position for Runway 13 and receiving clearance. The pilot indicated something needed to be reset. No assistance required.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The operator reported that the company standard operating procedures (SOPs) state that prior to cabin door close-up, the propeller tie will be removed from the left-hand (LH) propeller and stowed. Due to the pre-departure work load, the crew member responsible for removing the propeller tie missed removing it before the cabin door was closed. Engine start up resulted in a failure of the propeller tie. The crew was advised of this by other company personnel, who witnessed the event, causing the aircraft to return to the ramp. An inspection of the aircraft noted no damage, and the aircraft resumed operations. No further action.

A privately registered Piper PA-46-350P from Fort McMurray, AB (CYMM) to Lac La Biche, AB (CYLB) rejected its takeoff and requested a high speed taxi along the runway. The aircraft exited and conducted a run-up on Apron 02, then returned to the ramp. At 2315Z, the pilot called the tower and reported that the aircraft was missing some bolts. The runway and taxiways were inspected, and two small screws were found. One VFR departure, a McMurray Aviation Cessna 208B (C-GWRK) from Fort McMurray, AB (CYMM) to Fort Chipewyan, AB (CYPY), was delayed by 10 minutes.

A Synergy Aviation Cessna 172S (C-GUTC) from Grande Prairie, AB (CYQU) to Grande Prairie, AB (CYQU) rejected its takeoff due to a rough running engine. The aircraft taxied back to the ramp with no issues, and advised consulting with a mechanic and re-attempting takeoff in a half hour. No impact to operations.
