Airport OOA
N334SL has since been reassigned. It is now registered to a different aircraft (AMOR FATI INDUSTRIES INC ARGO), which was not involved in this event.
Aircraft involved
Probable cause & findings
The student pilot's failure to maintain directional control during landing with a left quartering tailwind, which resulted in a runway excursion, impact with a snowbank, and a nose-over.
Factual narrative
The solo student pilot reported that during the landing roll, while reaching for the flap levers, the airplane veered left, exited the runway to the left, struck a snowbank, and nosed over. The airplane sustained substantial damage to the vertical stabilizer. The student 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 15 minutes after the accident, the wind was from 170° at 11 knots. The airplane landed on runway 31.
