Probable cause

The pilot's failure to maintain directional control of the airplane and the pilot's inadequate compensation for the crosswind which resulted in a ground loop and subsequent collision with a taxiway sign. Factors contributing to the accident include the crosswind and the taxiway sign.

Analysis

The pilot was landing the tailwheel aircraft on runway 27 (4,001 feet by 75 feet, asphalt) with a right-hand crosswind. The pilot stated that upon touchdown "contact came before alignment was complete" and the airplane turned to the right. The pilot reported that he "overcompensated and got into an oscillation" and the airplane ground looped. The airplane departed the right side of the runway and struck a taxiway sign. The pilot stated in his accident report that the accident could have been prevented by performing a go around. Wind conditions reported at an airport, located 15 nautical miles east of the accident site, were: 350 degrees at 8 knots.

Factual narrative

The airplane was substantially damaged when it ground looped and impacted a taxiway sign following a landing on runway 27 (4,001 feet by 75 feet, asphalt). The pilot reported that as he was on final he was crabbing into the wind to maintain the runway centerline. When he approached the runway, he applied aileron into the wind and left rudder "to align with the centerline and cancel drift." The pilot reported that he contacted the runway before the alignment was complete and the airplane turned to the right. The pilot reported that he "over-compensated and got into an oscillation" and the airplane ground looped. The airplane subsequently departed the right side of the runway and struck a taxiway sign. The pilot stated in his accident report that the accident could have been prevented by performing a go around.

Wind conditions reported at Bolton Field Airport, 15 nautical miles east of the accident site, near the time of the accident were: Wind 350 degrees at 8 knots.
