Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The passenger heard a loud mechanical noise from the tail of the aircraft during rollout from a touch-and-go landing. The pilot was unable to maintain directional control, the aircraft ground looped, the main landing gear collapsed, and the wings were substantially damaged. Chevron-shaped skid marks were left by the tail wheel. The pilot attributed the loss of control to an improperly seated tailwheel locking pin.
