Probable cause
The pilot did not maintain directional control while landing on a snow-contaminated runway.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
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.
Factual narrative
The pilot reported that he made a normal touchdown in the tailwheel equipped airplane onto the centerline of the snow packed runway. Approximately halfway down the runway, the pilot reversed thrust in an effort to slow the airplane down. Shortly after entering reverse, the airplane veered approximately 5 degrees to the right. The pilot applied left brake and rudder to correct the turn; however, there was limited braking action on the runway surface and the airplane continued to the right. About three quarters 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.
