NTSB Narrative Summary Released at Completion of Accident

THE CESSNA 150 HAD BEEN MODIFIED WITH A CUSTOM AIRCRAFT/TAILWHEEL CONVERSTION (STC SA-2846-SW) AND AN AERO-SKI CONVERSION (STC SA-672-GL). THE PILOT REPORTED THAT HE EXPERIENCED A 'SEVERE' TAIL WHEEL SHIMMY AND A LOSS OF DIRECTIONAL CONTROL AFTER TOUCHING DOWN ON A PAVED RUNWAY. THIS WAS THE FIRST PAVED RUNWAY LANDING AFTER AN ANNUAL INSPECTION WAS PERFORMED ON THE AIRPLANE. THE AIRPLANE GROUND LOOPED AND ITS LEFT MAIN LANDING GEAR COLLAPSED. BEFORE THE ANNUAL INSPECTION, THE PILOT REQUESTED THAT PROBLEMS WITH TAIL WHEEL STEERING BE CHECKED. IMPACT DAMAGE TO THE TAIL WHEEL ASSEMBLY PREVENTED A DETERMINATION OF THE EXISTENCE OF ANY PREIMPACT MALFUNCTION.

NTSB Probable Cause Narrative

LOSS OF THE TAIL WHEEL STEERING DUE TO UNDETERMINED REASON(S).
