Event Description
On an unspecified date, two airplanes were involved in a ground collision at an airport. The first airplane was parked with its pilot and co-pilot inside. After re-entering the aircraft and engaging in conversation, the pilot felt the airplane shake and heard a loud noise. Looking out the right window, he observed an aircraft with its propeller hitting the right wing of his airplane.
Pilot Reports
The pilot of the parked airplane reported no preaccident mechanical malfunctions or failures that would have precluded normal operation. Substantial damage occurred to the right wing.
The pilot of the second airplane reported that, following engine start and before taxi for takeoff, he was focused on his navigation communications and did not notice his airplane rolling forward. He stated that he believed the hand brake was fully engaged. The airplane rolled forward and collided with the parked airplane. The pilot also reported no preaccident mechanical malfunctions or failures. The second airplane sustained minor damage.
Conclusion
Neither pilot reported any mechanical issues. The pilot of the moving airplane attributed the collision to his distraction and incorrect assumption about the hand brake.
