## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

FROM THE PILOT: THE LANDING WAS A NORMAL CENTERLINE WHEEL LANDING. AFTER THE TAILWHEEL SETTLED THE AIRCRAFT STARTED TRACKING LEFT. I APPLIED INCREASING RIGHT RUDDER ATTEMPTING TO ARREST THE LEFT TRACK. FULL RUDDER HAD NO EFFECT, I THEN APPLIED RIGHT DIFFERENTIAL STEERING AND CORRECTED THE LEFT TRACK, AS AIRCRAFT MOVED TO CENTERLINE, I ATTEMPTED TO ARREST THE RIGHT TRACK WITH FULL LEFT RUDDER AND THEN BY APPLYING FULL LEFT BRAKE. THE AIRCRAFT SKIDDED 75?TO 100? ON THE CENTERLINE BEFORE VEERING TO THE RIGHT. APPROXIMATELY 15 FT FROM THE RUNWAY EDGE THE LEFT GEAR COLLAPSED FROM THE SIDE LOADING THE INERTIA COMPLETED THE GROUND LOOP.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
