American Champion Aircraft 8GCBC N242BC accident near Unalakleet, Alaska

Probable cause

The pilots encounter with an obstructed dip in the landing surface during the landing roll out on a remote airstrip, which resulted in a noseover.

NTSB analysis

The pilot landed a tailwheelequipped airplane on a remote airstrip. During the landing rollout, while reducing engine power and holding the control stick fully aft, the airplane encountered an obstructed dip in the airstrip surface. As the airplane rolled through the dip, the pilot was unable to arrest the resulting nosedown pitch. The airplane subsequently nosed over and came to rest inverted, sustaining substantial damage to the rudder and left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions that would have precluded normal operation of the airplane.
