Aircraft involved
Probable cause & findings
THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING THE LANDING ROLLOUT.
Factual narrative
THE PILOT REPORTED THAT HIS AIRPLANE HAD BEEN MODIFIED BY THE INSTALLATION OF A TAIL WHEEL ASSEMBLY. ACCORDING TO THE PILOT, HE LANDED ON RUNWAY 12 AND DURING ROLLOUT LOST DIRECTIONAL CONTROL. THEREAFTER, THE AIRPLANE GROUND LOOPED. AT THE TIME THE WIND WAS FROM 120 DEGREES AT 5 KNOTS. DURING THE POST-ACCIDENT EXAMINATION OF THE AIRPLANE NO EVIDENCE WAS FOUND OF ANY MECHANICAL MALFUNCTIONS. THE PILOT REPORTED HAVING 600 HOURS OF TAIL DRAGGER FLIGHT TIME.
