After the airplane left the runway surface, the airplane hit a bump and "ground-looped." The pilot added that this accident could have been avoided by executing a crosswind landing with greater proficiency. The pilot further reported that there were no mechanical malfunctions or failures with the airplane. ## Factual narrative While performing a landing in gusty crosswinds, the student pilot lost directional control of the tail-wheeled airplane and veered off the 4,000-foot by 75-foot runway.
