Probable cause

The pilot's failure to maintain directional control of the airplane during landing in gusting wind conditions, which resulted in a ground loop.

Findings · 4

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 of the tailwheel equipped airplane stated that during landing, the airplane did not want to "settle" to the runway due to gusting winds. He further stated that upon touchdown the airplane ground looped to the left. The airplane sustained substantial damage to the fuselage, right wing, and right wing lift strut. The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A review of local weather from an automated weather observation station located about 10 miles to the northwest, showed that about 15 minutes before the accident the wind was variable at 6 knots, visibility 10 statute miles, and few clouds at 4700 feet above ground level. However, the pilot reported the wind at the accident site as 170 degrees true, 8 knots, gusts to 20 knots, and he was landing runway 18.
