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 Carson Air Ltd. Beech 1900D (C-FBTR/CRN511) from Kelowna, BC (CYLW) to Prince George, BC (CYXS) experienced an issue with its landing gear while on approach to CYXS. The pilot decided to return to CYLW. The aircraft landed at CYLW at 1759Z without issue, with the Aircraft Rescue and Fire Fighting (ARFF) unit on standby. The pilot did not declare an emergency.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. On approach into Prince George, BC (CYXS), the flight crew of CRN511 had no green "gear down" annunciation. Once the crew had established that the landing gear was down and locked, they chose to return to Kelowna, BC (CYLW), where maintenance could address the issue. Maintenance found that the landing gear green annunciators were unlatched and would only show green when pushed in and held. Once the annunciators were manually reset, they functioned normally. The flight crew had inadvertently unlatched the annunciators during flight, which caused the indication to be lost. The flight crew have been briefed on annunciator operation.
