Incident at Gahcho Kue, NT (CGK2)

TSB Report #A21W0003: C-GSAX, a Summit Air Charters Dornier 228, was operating as flight SU1022 from Gahcho Kue, NT (CGK2) to Yellowknife, NT (CYZF) with 2 flight crew and 6 passengers on board. The aircraft had arrived from CYZF on an IFR flight in IMC with the engine inlet anti-ice on. After arriving, they were on the ground for 10 to 15 minutes, unloading and loading, with the aircraft parked into wind. There was blowing snow, with the wind speed at 25 knots, gusting to 30 knots. Once the passengers were loaded, the aircraft was started and taxied to the button of the runway. The captain was not satisfied that they had sufficient runway visibility, so they taxied back to the ramp and faced into the wind again to await the arrival of an inbound IFR aircraft. After 15 minutes had passed, the arriving aircraft landed and gave a pilot report that there was more than 1 mile visibility. SU1022 then took position on the runway and departed CGK2 with the bleed air on, the propeller and engine inlet anti-ice off and the engine ignition in the off position. At 400 feet AGL, the power was set to climb power and the propeller and engine inlet anti-ice were turned on in anticipation of entering a cloud at 700 feet AGL. As the aircraft passed 1000 feet AGL and commenced a turn towards CYZF, both engines (Garrett TPE331-5-252D) flamed out. The captain cycled the power levers back and forth and was about to feather the propellers in preparation to glide back to the field when they noticed that the engines still had temperature and oil pressure. The captain switched the manual ignition on, and both engines relit. With engine parameters stabilized, the crew elected to proceed to the destination and landed without further incident. Maintenance update: Both engines were borescoped for damage, and none was found. All systems were checked and verified as operational. An engine check run was completed, with all systems functioning normally, and the aircraft was returned to service. Operations update: In consultation with the engine manufacturer (Honeywell) and the airframe manufacturer (Ruag), Summit Air Charters has updated its Dornier 228 SOPs and checklists in regards to the definition of icing conditions. The updates apply to when the application of engine inlet heat and propeller heat occurs, as well as when the ignitors are turned on and for how long the ignitors remain on.

A Jazz Bombardier CL-600-2B19 (C-FDJA/JZA8790) from Montreal/Pierre Elliott Trudeau, QC (CYUL) to Saint John, NB (CYSJ) declared "PAN PAN" to indicate a pressurization issue. The pilot then reported that they were able to control the cabin pressure manually and assistance was no longer required. The aircraft landed at 0149Z without incident. No impact on operations.
UPDATE: TSB Report #A21A0023: C-FDJA, a Bombardier CRJ 200 aircraft operated by Jazz was conducting flight JZA8790 from Montreal/Pierre Elliott Trudeau, QC (CYUL) to Saint John, NB (CYSJ). At approximately 21h25 AST, the aircraft was descending through FL250 at approximately 96NM W of CYSJ when the crew noted a gradual loss of cabin pressurization. They made contact with the Moncton (YQM) Area Control Centre (ACC) to declare "PAN PAN" and provided details on the nature of the problem. Working through the QRH and Emergency Checklist enabled the crew to stabilize the cabin altitude by switching from Auto to Manual mode. Subsequent contact was made with YQM ACC to advise that the pressurization issue was under control and the crew requested to downgrade from "PAN PAN" status to regular flight status. The aircraft landed safely at about 22h55 AST. None of the passengers or crew were physically affected by the loss of pressurization control. Company maintenance determined that the right-hand (RH) outflow valve was not closing fully. The secondary outflow valve and the Cabin Pressure Selector Panel were replaced and the aircraft was returned to service. Maintenance has submitted an SDR to Transport Canada.

Incident at FORT ST. JOHN BC (CYXJ)

A North Cariboo Flying Service Ltd. Beech 200 (NCB911) from Fort St. John, BC (CYXJ) to Kelowna, BC (CYLW) returned to the ramp after receiving a clearance and taxiing to position on Runway 21, citing a mechanical issue. No impact on operations.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The operator reported that the aircraft was taxied to accomplish pre-flight operational checks. It was discovered that the left-hand (L/H) bleed air fail light would not extinguish, and the aircraft returned to the apron. The company’s maintenance department conducted troubleshooting for the left bleed air system. A sense tubing leak was found just inside the fuselage on the forward run. The damaged tubing section was replaced, and the bleed air line in the area was inspected for signs of leakage, with none found. The L/H bleed air fail warning system was function checked with regulated shop air from the manifold, with no fault found. The aircraft was returned to service. No further action.

May 13, 2020

Incident at FORT ST. JOHN BC (CYXJ)

A North Cariboo Flying Service Beech 200 (NCB2042) from Calgary, AB (CYYC) to Fort St. John, BC (CYXJ) had a negative gear indication on final for Runway 30 and elected to go around to troubleshoot. Aircraft had positive indication after 15 minutes of circling and landed on Runway 30 without issue. No impact to operations.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The crew of NCB2042 climbed to 4000 above sea level (ASL) on the departure end of Runway 30, levelled, and slowed to 140 Knots to begin troubleshooting. Once slowed, the crew attempted to extend the landing gear again, and this time received no green "Gear Down" indications. Pressing the bulbs to test them revealed that none of the bulbs were testing properly, and the gear unsafe handle was not illuminated at this time. The crew then consulted Maintenance Operations Control (MOC), as they needed someone who knew the system far better and could confirm that the gear was down and locked in position for landing. At this time, the crew began running through additional troubleshooting items to confirm the gear position. They confirmed with MOC that the gear warning system was working normally as in the missed approach, they reduced power levers once levelled off and hit the warning horn, and the red handle was working. At the request of MOC, the crew performed the test of the systems once more (the gear had been left down when they began troubleshooting) and they maintained normal gear and locked signals. A suggestion was made to remove the indicator bulbs and place them in different positions. As soon as the "Left Main Gear Down" indicator was removed from its socket, the "Right Main Gear Down" indicator illuminated in the "Full Bright" position. The crew then placed the "Left Main Gear Down" indicator bulb back into the socket and, as soon as the bulb was reinstalled, the "Nose Gear Down" indicator illuminated "Full Bright" as well. MOC then recommended moving the nose gear bulb into the left main gear socket to confirm the gears position. The crew proceeded as instructed and found the lamp illuminated, confirming that the left main landing gear (MLG) was down. All 3 green "Gear Down and Locked" indicators illuminated, with no unsafe indications, and a normal landing was then executed. The aircraft was then inspected by the company’s maintenance department, where they discovered that the light socket length between the NLG and MLG was different lengths, which caused the NLG bulb holder to bottom out before test circuit could make contact. Maintenance swapped the bulb holder for the NLG and left-hand (LH) MLG position, and all lights tested satisfactory. All part numbers for the light assemblies are the same and the discrepancy between the MLG and NLG holders appears to be due to the particular installation in the aircraft. When the assemblies were swapped around, they were able to adjust the height enough to gain more clearance between the fisheye "Push-to-Test" light and the edge light panel assembly. The aircraft was returned to service, no further action required.

February 8, 2020

Incident at STEWART BC (CZST)

TSB Report #A20P0025: C-GLAH, an Aerospatiale AS 350 B-2 operated by Access Helicopters, was flying down a mountain near Stewart, BC to pick up skiers when the right-hand side cargo door departed the aircraft, damaging the tail boom and the tail rotor blades. The pilot was able to land normally. The cargo door was equipped with hinges at the top and with a single latch in the bottom center (additional, after-market latches are available for this door). None of the cargo inside the compartment fell out. Airspeed at the time the cargo door departed was about 125 knots. It was not determined why the cargo door opened.

January 7, 2020


At 0455Z, a Pacific Coastal Airlines Beech 1900D (C-GPCE/PCO615) on a flight from Vancouver Intl, BC (CYVR) to Cranbrook/Canadian Rockies Intl, BC (CYXC) requested assistance due to a possible landing gear issue. The aircraft landed without incident at 0510Z.
UPDATE TSB Report #A20P0004: C-GPCE, a Pacific Coastal Airlines Beech 1900D, was conducting flight PCO615 from Vancouver Intl (CYVR), BC, to Cranbrook/Canadian Rockies Intl (CYXC), BC, with 2 crew members and 12 passengers on board. During the approach into CYXC, when the crew selected “GEAR DOWN”, the landing gear in transit light remained illuminated and none of the landing gear down lights illuminated. The crew conducted a missed approach and requested radar vectors to allow them to conduct their abnormal landing gear indication checklists. On completion of their checklists and manual extension of the landing gear, they had heard the landing gear extend, had a green nose landing gear down indication and had no landing gear warning horn with the flaps in the landing configuration. The crew determined they were safe to land with the indications present and requested the approach to CYXC with ARFF to be on standby as a precaution. The aircraft landed without incident. Maintenance conducted a number of landing gear swings and did functional checks on the landing gear electrical systems with no fault found. The aircraft has been returned to service.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. Follow-up on landing gear failure for C-GPCE resulted in the following assessment: Through operational experience, moisture accumulated in the landing gear relay located in wing caused landing gear operation failure due to freezing. A new sealed relay installed through a Supplemental Type Certificate (STC) has been installed on company aircraft with exception of this newly acquired aircraft. The new sealed landing gear relay has now been installed and no further gear failure has been experienced.

Accident at OLDS-DIDSBURY AB (CEA3) (Aerodrome, runway or taxiway shutdown)

A Springbank Air Training College Ltd. Cessna 172P (C-GSKF) from Calgary/Springbank, AB (CYBW) to Olds-Didsbury, AB (CEA3) landed short of the runway, causing the nose wheel to separate. The aircraft came to rest on the runway. A NOTAM was issued, closing the runway until the aircraft was removed. No impact to NAV CANADA operations. One VFR aircraft was diverted to a nearby aerodrome.
UPDATE: TSB Report #A20W0079: C-GSKF, a Cessna 172P aircraft operated by Springbank Air Training College, was being used for a private pilot flight test originating from and returning to Calgary/Springbank, AB (CYBW), with one pilot examiner and one student pilot on board. As part the flight test profile, an inspection pass exercise was being conducted on Runway 28 at Olds-Didsbury, AB (CEA3). After the inspection pass, the student pilot performed a go-around and, at that time, the engine (Avco Lycoming O-320-DJ2) lost power. Control was passed from the student to the pilot examiner (PIC). The PIC elected to conduct an immediate left turn to join the downwind for landing on Runway 28. While maneuvering to land on Runway 28, the left wing tip contacted the snow covered grass area north of and adjacent to the threshold of the runway. Shortly after, the nose contacted the ground, resulting in the collapse of the nose landing gear, and damage to the propeller. The aircraft continued to slide on a track of approximately 310°M, until it contacted a ditch that runs parallel to and north of the runway. The aircraft came to rest facing in a near north direction. The aircraft was substantially damaged, but no injuries were reported. Post-accident inspection by maintenance found that there was little fuel remaining in the aircrafts fuel system.

A Helijet International Sikorsky S-76A (C-FZAA/JBA905) enroute from Vancouver/Harbour (Public), BC (Heli) (CBC7) to Nanaimo Harbour, BC (Heli) (CDH5) called PAN PAN with control issue. The aircraft diverted to Vancouver Intl, BC (CYVR) and landed at helipad Charlie. Aircraft Rescue and Fire Fighting (ARFF) responded.
Update TSB Report #A19P0168: C-FZAA, a Sikorsky S-76A helicopter operated by Helijet International, was conducting flight JBA905 from Vancouver Harbour Heliport (CBC7), BC to Nanaimo Harbour Heliport (CDH5), BC with 2 crew and 8 passengers on board. When the aircraft leveled off at 1000 feet ASL, the pilot flying (PF) felt binding in the cyclic (roll axis). Thinking it was an issue with the cyclic force trim, the PF attempted to clear the problem by engaging the R/H cyclic trim button several times and informed the pilot monitoring (PM) of the situation. The PM checked the pressure gauges and the caution system for abnormalities and found none. The PF passed rotorcraft control to the PM to confirm the binding and to check the force trim release on the L/H cyclic. After troubleshooting did not clear the binding in the cyclic, the crew decided to divert to Vancouver Intl (CYVR), BC and declared a PAN PAN requesting priority for a runway. In close proximity to the airport, the binding in the cyclic ceased and the crew chose to land on the helipad with the option of using the connected taxiway for a run on landing if necessary. The rotorcraft landed safely and taxied in. Upon inspection, Helijet maintenance found that the Magnetic Brake was sticking "on". They installed a serviceable Magnetic Brake assembly, conducted a satisfactory flight control freedom of movement inspection, and the aircraft was returned to service.
