Aircraft Accident/Incident Report
Yellow Pine, Idaho 83677
Tuesady, February 14, 2012 12:30 MST
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that he made a normal touchdown in the tailwheel-equipped airplane onto the centerline of the snow packed runway. He said that about halfway down the runway, he applied reverse thrust in an effort to slow the airplane. Shortly after entering reverse, the airplane veered about 5 degrees to the right. The pilot applied left brake and rudder to correct the turn; however, the airplane continued to the right due to the limited braking action on the runway surface. About three-quarters of the way down the runway, the airplane struck an ice chunk and the right main landing gear collapsed. The airplane’s right wing was substantially damaged. The pilot reported no mechanical failures or malfunctions that would have precluded normal operations.
NTSB Probable Cause Narrative
The pilot did not maintain directional control while landing on a snow-contaminated runway.
