A Nav Air Charter Mitsubishi MU-2B-36 crashed into trees shortly after takeoff from Terrace Airport on a courier flight to Vancouver. The left engine failed due to a fatigue crack, and both pilots were killed.

Accident Overview and Immediate Sequence of Events On 1834 Pacific standard time, a Nav Air Charter Inc. Mitsubishi MU-2B-36 aircraft, registration C-FTWO and serial number 672, departed Runway 15 at Terrace Airport for a courier flight to Vancouver, British Columbia. Shortly after takeoff, the left engine lost power. The aircraft descended with a slight left bank and struck trees approximately 1,600 feet east of the departure end of Runway 15 while on a heading of 072° magnetic. The impact and subsequent post-crash fire destroyed the aircraft, resulting in the fatal injuries of the two pilots on board.

Probable cause

The left engine combustion chamber plenum split open due to a fatigue crack, causing the engine to flame out. The crew did not feather the left engine or retract the flaps, and the aircraft entered a moderate left-hand turn after take-off; the resulting drag caused the aircraft to descend until it contacted trees.
