Amateur-built RV4 N311SV accident near Milton, Florida

Probable cause

The pilot's failure to maintain directional control during a crosswind landing.

NTSB analysis

The pilot was landing the tailwheel-equipped airplane and reported that on final approach the wind increased from calm to a quartering left crosswind at 9 knots. During the landing roll, a gust of wind pushed the airplane to the left. The pilot applied rudder and brakes, but the airplane skidded sideways on the runway resulting in a ground loop. During the accident sequence the left main landing gear collapsed and the left wing impacted the runway. The airplane’s engine mount was also substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation.
