Cessna 170B N2629D accident near Columbia, California

Probable cause

The pilot's failure to maintain directional control during landing roll.

NTSB analysis

The pilot reported that after conducting a three-point landing on runway 17, the tailwheel-equipped airplane began to turn to the left. The pilot applied right rudder for correction and the airplane turned to the right. The pilot then immediately applied full power and left rudder with no result from either input. The aircraft continued to turn to the right and the left wingtip contacted the runway surface. The airplane exited the right side of the runway and nosed over, resulting in structural damage to the empennage and wings. The pilot reported that the wind at the time of the accident was from 160 degrees at 6 knots. Examination of the airplane by a Federal Aviation Administration (FAA) inspector revealed no mechanical anomalies with the engine or airframe that would have precluded normal operation.
