GRUMMAN ACFT ENG COR-SCHWEIZER G 164A near Bakersfield, CA — 2015-06-09

Probable cause

The pilot's failure to maintain directional control during the landing roll, resulting in a runway excursion, and a collision with terrain.

NTSB narrative

The pilot reported that during the landing roll, a right quartering tailwind pushed the tail to the left, the airplane exited the dirt strip to the right, where the lower right wing of the bi-plane struck an embankment. The airplane collided with a ditch and nosed over, sustaining substantial damage to both the upper and lower left wings. The pilot reported no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
