Probable cause

The pilot's failure to compensate for the wind conditions during the takeoff roll, which resulted in a collision with a tree. A factor contributing to the accident was a crosswind.

Analysis

The commercial certificated pilot reported that he was departing a remote mountain ridge on a Title 14, CFR Part 135 cross-country air taxi flight. The takeoff area was about 500 feet long, and about 15 feet wide. The pilot said he departed downhill with a 10 mph quartering tailwind. About 250 feet from the starting point, the pilot said that the crosswind pushed the airplane to the right, and the right wing collided with a tree. The airplane veered to the right, and the left main landing gear collapsed. The airplane received structural damage to the right wing.
