A commercial pilot on a Part 135 air taxi flight reported a collision with a tree during takeoff from a remote mountain ridge, resulting in right wing damage and left main landing gear collapse.

Introduction

A commercial certificated pilot was conducting a Title 14, CFR Part 135 cross-country air taxi flight from a remote mountain ridge. The takeoff area was approximately 500 feet long and 15 feet wide. The pilot reported that the departure was performed downhill with a 10 mph quartering tailwind.
