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 tailwheel equipped airplane veered to the left during the landing roll and nosed over when the pilot attempted to correct by utilizing the airplane’s brakes. The airplane sustained substantial damage to the fuselage and left wing. The right tailwheel spring was found disconnected. Subsequent inspection of the right tail-wheel spring revealed tooling marks, and that the attachment loop had been closed back towards its original radius. When asked about the tooling marks on the separated spring, the pilot/owner suggested they may have occurred during a previous annual inspection or “when it fell off a few years ago when I had a bad tailwheel shimmy.” At the time of the accident, the pilot was landing the airplane on runway 32 with wind from 250° at 5 knots.
