Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, after departure, he flew south along a river for about 5 miles. He then turned east toward his destination airport and 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.
