Airport GTF
Aircraft involved
Probable cause & findings
The pilot’s failure to maintain lateral control of the airplane during takeoff in a quartering tailwind.
Factual narrative
The pilot of the tailwheel-equipped airplane reported that during takeoff, the right wing "came up quickly (lifted) and unexpectedly." He attempted to recover, but the left main landing gear sideloaded and collapsed. The left wing impacted the runway and the airplane rotated to the left 180° and came to rest on the runway. 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. The automated weather observation station located on the airport reported that, about 7 minutes before the accident, the wind was from 320° at 14 knots. The airplane was departing on runway 21.
