Aircraft flight hours:

Circumstances:
The purpose of the flight was for the second pilot to perform an evaluation of the first pilot, who was recently designated by the operator as a backup pilot. Following several successful flights with and without passengers, the pilots discussed single engine operations, and the first pilot reduced the right engine's power to flight idle and feathered the propeller. During the final leg of the approach to landing, the airplane crossed over a fence near the runway threshold, and the first pilot pitched the airplane downward. The nose landing gear contacted the runway "hard," and the airplane began to bounce. After several bounces, the first pilot elected to abort the landing, increased power on the left engine to "full." As the first pilot pitched the airplane upward, it yawed to the right, "stalled," and impacted the ground.
Probable cause:
The pilot's improper flare and recovery from a bounced landing, which resulted in a stall and subsequent impact with the ground.

The North-Wright Airways Ltd. DHC-6 Twin Otter, registration C-FMOL, was departing from an approximately 1,500 foot long gravel strip at Mile 222 of the Canol Road (near the Tsichu River), Canada. The takeoff was initiated to the north and into wind. Immediately after becoming airborne, the aircraft encountered a strong right cross-wind and settled back onto the strip. The left wheel contacted willows that had overgrown the edge of the strip. The aircraft veered left into the willows at about 60 knots, and began to decelerate. Prior to flying speed being regained, the aircraft rolled off the end of the strip and come to rest in a shallow creek. The right wing partially separated from the fuselage at impact and the forward fuselage, nose gear and right main gear sustained substantial damage. The pilot and first officer were uninjured. The purpose of the trip was to move hunting gear and outfitter supplies back to an airstrip at Mile 170 of the Canol Road (Godlin Lake). The aircraft was at or near gross weight at the time of the occurrence.
