Aircraft involved

Probable cause & findings

The pilot’s failure to ensure that the runway was clear of any obstacles before departure, which resulted in the airplane impacting a snowdrift.

Factual narrative

The pilot of a tailwheel-equipped airplane reported that during takeoff from a remote airstrip, the airplane impacted a snowdrift and was "launched" into the air. Subsequently, he heard something break. He added that the airplane appeared to be fine with no indications of a problem other than the left tire "looked a little off". The pilot returned to his original departure airport without further incident. During a post-accident examination, his mechanic discovered that the tubing in the bottom of the fuselage where the olio strut attached to the main landing gear was broken. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. As a safety recommendation, the pilot added that walking the runway prior to takeoff might have revealed the snowdrift.
