Airwave flight 9806, a G-159 Gulfstream I, was flying IFR from Toronto (YYZ) to Montreal-Dorval (YUL). When it was on final for runway 06R, the pilot reported a problem with the landing gear. The crew recycled the gear and performed the emergency extension procedure unsuccessfully before trying various flight manoeuvres to free the gear. They then circled Montreal until minimum fuel was reached, declared an emergency and landed. On landing, the aircraft veered to the left and came to a halt 60 feet from the runway. Both pilots escaped uninjured and the aircraft was damaged beyond repair.

Probable cause:

Preliminary investigation revealed that an apprentice AME moved a line in the landing gear well prior to the flight. The work was neither scheduled nor required. The apprentice left the work unfinished when he went to do something else, then forgot that a fastener was not in place. There was no flag or note to inform the other technicians or the crew that the aircraft was not in an airworthy state. The apprentice has two years experience with this company. The management was satisfied with the quality of his work. Two other licensed AMEs were working in the hangar with the apprentice. He was the only apprentice they had to supervise. The apprentice attended a type training course for this aircraft.

Circumstances:

The airplane was in cruise flight at 16,000 feet, in instrument meteorological conditions. About two minutes after the crew ceased cross-feeding due to a fuel imbalance, the left engine experienced a total loss of power. About one minute later, the co-pilot indicated to the pilot-in-command (PIC) that the airplane was losing airspeed, and about 15 seconds later, the co-pilot remarked "keep it up, keep it up." Shortly thereafter, the airplane departed controlled flight and impacted terrain. The airplane was destroyed by fire and impact forces. Examination of the left engine revealed no evidence of any pre-impact failures that would have accounted for an uncommanded in-flight shut-down. A SIGMET for potential severe clear icing was effective for airplane's flight path; however, the flight crew did not report or discuss any weather related problems around the time of the accident. At the time of the accident, the airplane was above its single-engine service ceiling. The PIC had accumulated approximately 6,000 hours of total flight experience, of which, about 500 hours were as PIC in make and model. The co-pilot had approximately 600 hours of total fight experience, of which, 300 hours were in make and model.

Probable cause:

The pilot-in-command's failure to maintain minimum control airspeed, which resulted in a loss of control. Factors in this accident were clouds, and a loss of engine power for undetermined reasons, while in cruise flight above the airplane's single engine service ceiling.
