This October 2008 accident report is provided by the National Transportation Safety Board. Published as an educational tool, it is intended to help pilots learn from the misfortunes of others.
Aircraft: Aviat Aircraft Inc. A-1B. Injuries: None. Location: Mooresville, N.C. Aircraft damage: Substantial.
What reportedly happened: According to the pilot, during a landing attempt the airplane touched down hard enough to bounce, then drifted to the right. The pilot attempted to regain control of the airplane by applying left rudder and aileron. The tailwheel touched down and abruptly swung to the right. The right main gear collapsed and the right wing hit the ground.
The post-accident examination found damage to the tailwheel. The accident inspector theorized that the first bounce had damaged the tailwheel, and when it touched down the second time, it caused the airplane to ground loop.
Probable cause: The pilot’s improper flare while landing.
