Primary finding

Probable cause

The pilot's failure to maintain adequate clearance from powerlines during the landing approach resulting in a collision.

Investigator assessment

Analysis narrative

The pilot stated that the purpose of the flight was to practice taxiing in his recently purchased airplane. While taxiing, the airplane unintentionally became airborne and the pilot decided that in an effort to not collide with an electric fence ahead, he would need to add full power and fly the airplane in a traffic pattern to come back and land. Despite being aware of a powerline in the area, the pilot collided with it during his third landing attempt. The pilot reported no preimpact mechanical malfunctions or failures that would have precluded normal operation.

Source record

Factual narrative

The pilot stated that the purpose of the flight was to practice taxiing in his recently purchased airplane. While taxiing, the airplane unintentionally became airborne which the pilot accredited to a combination of a weather inversion, vortex generators, and a three-blade propeller which produced enough lift at a slow groundspeed. The pilot decided that in an effort to not collide with an electric fence ahead, he would need to add full power and fly the airplane in a traffic pattern to come back and land. The pilot maneuvered to land on his grass strip and aborted the landing after assessing that the terrain would not be suitable. He maneuvered to an area about 0.5 miles away knowing that the terrain would be flat and adequate length. He was familiar with the area and knew that powerlines ran perpendicular to his flight path. During the approach, he again elected to go-around and configured the airplane for his third attempt to land. While on the final approach, the pilot reduced the power and the airplane rapidly lost altitude, resulting in a collision with the powerlines and collision with the ground. The pilot reported no pre impact mechanical malfunctions or failures that would have precluded normal operation.
