Airport B21

Aircraft involved

Probable cause & findings

The pilot’s failure to maintain clearance from trees while maneuvering at a low altitude.

Factual narrative

The pilot reported that after departure he flew south along a river for about five miles. He then turned east toward his destination airport, but needed to climb over a mountain ridge. During the climb, the landing gear impacted the top of trees; subsequently, the airplane nosed down and impacted terrain. The airplane sustained substantial damage to the fuselage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
