Probable cause

The pilot's failure to maintain directional control during landing rollout in gusty crosswind conditions, which resulted in a ground loop and subsequent substantial damage to the airplane.

Findings · 4

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

According to the pilot, he overflew the runway, observed the windsock, and elected to perform a left quartering headwind landing. The approach and landing on runway 19 was "uneventful" and during the landing roll, the pilot applied left aileron and used both rudder pedals to maintain directional control. Then, the airplane began to veer to the left and "ground looped." The airplane sustained substantial damage to the rudder during the accident sequence. The pilot further reported that a mechanic indicated that the "tailwheel may be broken" which may have contributed to the ground loop. A postaccident examination revealed that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The winds reported at the airport about the time of the accident were from 120 degrees at 16 knots gusting to 23 knots.
