Incident at SASKATOON / JOHN G. DIEFENBAKER INTL SK (CYXE)
2005-01-14: UPDATE TSB reported that when the WestJet Boeing 737-281, C-FTWJ, arrived in Winnipeg, MB the No. 1 engine (Pratt & Whitney JT8D-17A) produced an unusual sound on shutdown. Maintenance personnel inspected the engine, conducted a power run, with no fault found. Consequently, the aircraft was released to complete a scheduled flight to Calgary, AB. In cruise at FL 310 approximately one hour and fifteen minutes into that flight, the No. 1 engine emitted a loud bang accompanied by a reduction in engine pressure ratio (EPR) indication. Additionally, there was a smell of exhaust fumes in the cockpit. The crew completed the items for the Engine Limit/Surge/Stall QRC, declared an emergency, and diverted to Saskatoon, SK. When the thrust lever for the No. 1 engine was retarded to idle in accordance with the QRC, the engine ran smoothly and the exhaust fumes dissipated. For electrical and pneumatic requirements, the engine was maintained at idle and the aircraft landed uneventfully at Saskatoon. Again no faults were evident after maintenance personnel completed additional inspections and power runs. The aircraft was subsequently re-positioned to Calgary, with essential crew only, for further inspection. The engine is being replaced due to suspected stator vane damage.
2005-01-11: WJA 96, a B737-200, was 80 miles south of Saskatoon at FL 310 on a flight from Winnipeg to Calgary when the crew advised that they had shut down the #1 engine. The crew declared an emergency and diverted to Saskatoon, where emergency services responded. The aircraft landed safely on Runway 27 at 2220Z. TSB will contact the company.
