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

Summary

2003-03-04: UPDATE Maintenance and Manufacturing reported that the aircraft was on a test flight to determine the maximum operating altitude. The procedure is to advance the thrust lever rapidly at 2,000 foot altitude increments until the test engine flames out. At FL 430, one engine flamed out during this procedure. Thus, the maximum alitude has been declared at FL 410.
2003-02-28: The crew of C-GBOT, a Lear 25, was conducting a test flight filed Regina to Regina at FL 430. When the aircraft was approximately 15 NM north of Saskatoon, the crew advised that one engine had flamed out and they needed to descend to FL 250. The aircraft started a descent without a clearance and was able to re-light the engine prior to reaching FL 250. The aircraft returned to land at Regina without further incident at 2055Z.
2003-03-06: UPDATE TSB reported that the Learjet 25B operated by West Wind Aviation, was on a test flight to check the right engine performance (GE CJ610 S/N 240226A) following maintenance action. The engine performance was satisfactory at FL 410, but when the check was carried out at FL 430 the engine flamed out. The crew advised ATC of the flameout and that they needed to descend. Before the Controller could issue a descent clearance the crew commenced a descent. The engine was re-started during the descent and the aircraft returned to Regina without further incident. The aircraft was placarded as restricted to a maximum altitude of FL 410 and was returned to service.
