Incident
at TERRACE BC (CYXT)
A North Cariboo Flying Service Ltd. British Aerospace Avro 146 (C-GSUI/NCB1512) from Calgary, AB (CYYC) to Terrace, BC (CYXT) experienced an engine failure on short final for Runway 33. The engine was shut down during the roll out. No impact to operations.
UPDATE: TSB Report #A22P0002: C-GSUI, a North Cariboo Flying Service Ltd. British Aerospace Avro 146 Series RJ100, was operating as flight NCB1512 from Calgary Int’l, AB (CYYC) to Terrace, BC (CYXT) with 4 crew and 77 passengers on board. On short final for an ILS approach, at approximately 400 feet above ground level, the aircraft encountered wind shear, causing an aerodynamic performance degradation and deviation from the glide slope. The aircraft auto-throttle system compensated for the performance change and enabled the crew to regain the glide slope. The crew then observed a GEN 4 caution light for the No. 4 engine (Avco Lycoming, LF-507-1F) and noted the engine continued to produce power based on the associated gas producer speed (N1) indication. The crew proceeded with the landing and touched down without further incident. Once on the ground, the crew found the No.4 engine was now indicating a decrease in N1 with an exceedance in the exhaust gas temperature (EGT) limitation. The No. 4 engine was shut down on the taxiway, with no additional indications or warnings. There were no reported injuries or damage to the aircraft. Following arrival, the crew inspected the engine and no damage or leakage was found. When weather permits, the aircraft will be ferried on the 3 remaining engines to CYYC for completion of the required maintenance actions.
