NTSB GAA18CA488 · 2018-08-12 · Brooks Range, AK
Docket — crew, injuries and powerplant
Summary
The pilot in the tailwheel-equipped airplane reported that he took off from an off-airport unimproved, gravel surface. He recalled that the airplane climbed to about 300 ft before it encountered a "severe downdraft." The airplane subsequently descended and impacted a creek bed, and the main landing gear separated from the airframe. The airplane sustained substantial damage to the foremost fuselage bulkhead and stringers. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that the wind at the accident site was from 230° at 25 knots, gusting to 30 knots and that he was landing to the southwest.
