Aircraft involved

Probable cause & findings

The student pilot's failure to maintain directional control during landing in a left quartering headwind, which resulted in a ground loop.

Factual narrative

The student pilot reported that, during landing, shortly after touchdown, a "crosswind lifted the left wing" and the airplane veered left. He corrected with opposite aileron, but the airplane ground looped to the left and the right landing gear collapsed. The airplane sustained substantial damage to the lower right section of the fuselage. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located on the airport reported that, about 30 minutes before the accident, the wind was from 130° at 8 knots and about 15 minutes after the accident, the wind was from 100º at 9 knots. The airplane landed on runway 16R. The student pilot reported that, during landing, shortly after touchdown, a "crosswind…lifted the left wing," and the airplane "fishtailed." He said he and the instructor corrected by applying right aileron, but the airplane ground looped, and the right main landing gear collapsed. The airplane sustained substantial damage to the lower right section of the fuselage. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airport's automated weather observation station reported that, about 30 minutes before the accident, the wind was from 130° at 8 knots and that, about 15 minutes after the accident, the wind was from 100º at 9 knots.
