Amateur-built PTUNDRADACTYL N357WE accident near Friday Creek, Alaska

Probable cause

The pilot's excessive brake application during landing on a short runway due to his lack of familiarity with the toe brakes, which resulted in a nose-over.

NTSB analysis

The pilot reported that, during a test flight, he landed on an 800-ft-long off-airport, sand-and-gravel surface, and the airplane nosed over. The airplane sustained substantial damage to the rudder and right wing. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot added that the accident could have been prevented by landing on a surface that "would not [have] require[d] the use of much braking until I more fully acclimated myself to the toe brake setup in this plane and to sort out any braking pressure issues a little more thoroughly."
