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, while en route in mountainous terrain at night at 6,500 ft, he encountered turbulence and downdrafts, during which time, he "felt a couple of impacts on the left side." He continued to the destination airport, where he noticed the ELT was transmitting over the radio. During the landing, the left main landing gear collapsed. The pilot reported that he initially thought the airplane had struck a bird, but postaccident examination revealed that the left wing had impacted a tree. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
