Analysis
The student pilot of the tailwheel-equipped airplane reported that, during landing, the airplane ground looped, and the right main landing gear collapsed. He added that he believes he became complacent during the flight.
The airplane sustained substantial damage to the fuselage.
The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
A review of recorded data from the automated weather observation station located on the airport reported that, about 27 minutes before the accident, the wind was from 070° at 8 knots. The airplane landed on runway 31L.
