The NTSB's narrative final · quoted from the NTSB record
The pilot reported that, after touchdown, the airplane immediately turned hard right and that he then applied engine power. The airplane subsequently exited the runway while still turning right and came to rest on its left side. A postaccident examination of the airplane and the braking system revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.
