Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel-equipped airplane reported that, during the three-point landing, almost immediately after touchdown, the airplane veered to the left, ground looped to the left, and the right main landing gear collapsed. He added that the airplane came to rest facing 180° opposite of the landing direction in the grass off the left side of the runway. The airplane sustained substantial damage to the right wing and right aileron. He further reported that when loading the airplane onto the trailer for recovery, he noticed there was a crack in the right gear leg just above the weld to the axle. He added that 2/3 of the brake showed fresh metal, and the other 1/3 was rusted and corroded. The automated weather observation system located at the accident airport reported that, about the time of the accident, the wind was from 230° at 9 knots, gusting to 16 knots. The pilot landed on runway 20.
