Narrative:
A Pacific Coastal Airlines Beech 1900C, was conducting flight PCO866 from Port Hardy airport (CYZT), BC to Vancouver Int'l airport (CYVR), BC 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 aircraft's RH engine, a PT6A-65B (S/N: PCE32157), was indicating a significant reduction in torque and an increased interstage 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 monitoring declared an emergency (MAYDAY) and made the request to return to CYZT. The aircraft landed without further incident.
Subsequent maintenance actions revealed the engine's compressor turbine disk had experienced a blade failure, leading to other blades on the disk to fail. The operator's 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 engine's 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.
