All appropriate parties were advised and the aircraft arrived safety with no operational impact.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. Prior to entering the extended range twin-engine operations (ETOPS) portion of the flight, #1 engine oil filter bypass indication was annunciated. The crew carried out Quick Reference Handbook (QRH) procedures and the engine shut down un-commanded. The crew returned to Vancouver, BC (CYVR) and carried out an uneventful single engine landing. CYVR maintenance found the Transfer Gear Box (TGB) screen oil filter and the Oil Debris Monitor System (ODMS) sensor heavily contaminated with metal and heat damage on the fan frame strut panel that houses the radial drive shaft, indicating a potential radial drive shaft (RDS) bearing failure. A subsequent borescope inspection of the RDS bearing showed significant damage and material loss. The #1 engine oil smelled of hydraulic fluid, oil samples were taken and sent for analysis. The #1 hydraulic engine-driven pump (EDP) did not show signs of overheating/distress and the drive pad did not show signs of hydraulic fluid leaking. The engine was replaced. Service Difficulty Report (SDR) 20211213009 was filed, and an investigation with CFM and General Electric (GE) was ongoing.
UPDATE: TSB Report #A21F0224: C-GAMQ, a WestJet Boeing 737 MAX 8, was conducting flight WS1862 from Vancouver Intl, BC (CYVR) to Honolulu/Daniel K. Inouye Intl, HI (PHNL).

Incident at In the vicinity of: YELLOWKNIFE NT (CYZF)

At 0030Z, an Air Tindi Ltd. de Havilland DHC-6-300 (TIN606) from Whati, NT (CEM3) to Yellowknife, NT (CYZF), inbound, declared "PAN PAN" due to a loss of hydraulic pressure. At 0040Z, TIN606 landed safely on Runway 10. TIN606 shut down on Taxiway C and was towed in by the company. A foreign object debris (FOD) check was completed at 0047Z, with nothing found. No further impact to operations.
UPDATE: TSB Report #A21W0069: C-FATW, an Air Tindi de Havilland DHC-6-300 Twin Otter, was conducting flight TIN606 from Whati, NT (CEM3) to Yellowknife, NT (CYZF). While enroute, the flight crew identified that the flaps had not fully retracted. The hydraulic pressure was indicating 0 and the flaps were retracted manually. The flight crew declared an emergency on approach to CYZF and conducted a successful flapless landing on Runway 10. The aircraft was shut down on the taxiway and towed to the ramp.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. After departing from Whati, NT, the flight crew noticed that the flaps did not fully retract and the main hydraulic pressure gauge was showing zero pressure. The DHC-6 Emergency Procedures Quick Reference Handbook was called for and completed, which resulted in the flaps being retracted by use of the hand pump. The flight continued to Yellowknife, NT. Prior to landing, the hand pump was used again to re-pressurize the main hydraulic system, and a flapless landing was conducted. The aircraft landed without further incident and was able to taxi off the runway and shut down on the taxiway. Company maintenance inspected the aircraft hydraulic system and found the hydraulic pressure switch to be intermittent. This was causing the hydraulic pump relay to not turn the hydraulic pump on to maintain system hydraulic pressure. The hydraulic pressure switch was replaced and a function check of the hydraulic system was completed by testing the flaps and steering systems, with no further failure produced. The aircraft was returned to service and there have been no further reported incidents.

Aviation Incident Report #16698: A MAG Canada Aero Commander 500S (C-GJLO/BRDG159) from Muskoka, ON (CYQA) to Muskoka, ON (CYQA) and 3 de Havilland DHC 6 Twin Otters (Tanker 844, Tanker 846 and Tanker 847) were dispatched to a 1.1 hectare forest fire located 40 miles southeast of CYQA (Latitude 44 44.69 Longitude 78 27.25). The forest fire was visible from 30 miles and had a plume of smoke about 1000 feet high. While approaching the fire, BRDG159 made an initial radio call at 30 miles, using large lakes to describe the location of the fire. Shortly afterward, the pilot of an Ornge Global Air Agusta AW139 on a flight to Peterborough, ON (CYPQ) issued a position report, stating they were in the Haliburton-Peterborough corridor. At 10 miles, BRDG159 announced they were taking over the airspace over the fire and stated the intentions and the altitudes of all four aircraft. BRDG159 established the birddog over the fire at 3000 feet above sea level (ASL), while Tanker 844, Tanker 846, and Tanker 847 conducted an inspection of a lake 3 miles west of the fire. While inspecting the lake, one of the Tanker pilots reported that the Agusta AW139 was within 1 mile or less of the fire, at a low level. Likely due to the orbit of the birddog and the position of the helicopter, it was not seen from the birddog. Contact was not established with the Agusta AW139. During their debrief, the three Tanker pilots stated that the helicopter was at a low level and in their circuit pattern for the fire. If they had started bombing the fire, there would have been a serious risk of collision with the helicopter.
UPDATE: Correction of aircraft information for Tanker 844, Tanker 846, and Tanker 847. Narrative modified to read as follows: "A MAG Canada Aero Commander 500S (C-GJLO/BRDG159) from Muskoka, ON (CYQA) to Muskoka, ON (CYQA) and a Province of Ontario, Ministry of Natural Resources de Havilland DHC-2 MK. III (Tanker 844), a Province of Ontario, Ministry of Natural Resources de Havilland DHC-2 MK. III (Tanker 846), and a Province of Ontario, Ministry of Natural Resources de Havilland DHC-2 MK.

Accident at SASKATOON / JOHN G. DIEFENBAKER INTL SK (CYXE)

After landing, the landing gear of a Millennium Aviation Ltd. Piper PA 30 (C-FMIR) from Saskatoon, SK (CYXE) to Saskatoon, SK (CYXE) collapsed on Runway 27 at 2248Z. The Airport Rescue and Fire Fighting unit responded. Subsequent aircraft used Runway 33. C-FMIR was removed from the runway at 0019Z.
UPDATE: TSB Report #A20C0088: C-FMIR, a Piper PA-30 Twin Comanche operated by Millennium Aviation, was returning to Saskatoon/John G. Diefenbaker Intl, SK (CYXE) from a local training flight. Prior to landing, the pilots observed the main gear landing indicator light flicker. On final approach to landing, the main gear indicator light indicated that the landing gear was down and locked, the nose gear was confirmed visually down and locked, and there were no further abnormal indications or warnings. Upon touchdown on Runway 27 at CYXE, the left wing of the aircraft dropped and the aircraft skidded to a stop. The pilots exited the aircraft and observed that the left landing gear was not extended. Emergency crews responded. There were no injuries, but a NOTAM was issued to close Runway 27 for approximately 1.5 hours until the aircraft could be removed. A subsequent inspection by the operators maintenance revealed a damaged landing gear Teleflex cable.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The Millennium pilot reported that this was the 3rd flight of the day for the Piper Twin Comanche PA-30 (C-FMIR) (engines on at 2027Z). There were no issues identified during the pre-flight inspection. This was a training flight for the issue of a Multi-Engine Rating. Air exercises, including several gear extensions and retractions, were conducted, and no system issues were observed. The student pilot properly completed the downwind pre-landing checks, including verifying in the left engine mirror that the nose gear was down. This was then re-verified on final approach. After closing the throttles for landing, there were no warning lights or audible alarm (which would normally happen below 12" if there was a gear issue). Once established in a landing flair, the aircrafts left side dropped, and the student corrected for what they assumed was a sudden crosswind. After levelling off, the aircraft dropped to the runway as the landing gear collapsed. When the aircraft came to a full stop, the engines were secured with the checklist (2145Z). The tower was advised of the incident. The Millennium Person Responsible for Maintenance (PRM) reported that, upon an inspection by maintenance personnel, it was found that the cable controlling the left landing gear had broken apart. Repairs were deemed to be economically unfeasible.
