## Probable cause

THE TOTAL FAILURE OF THE LANDING GEAR TAIL WHEEL LOCK ON LANDING ROLL OUT, RESULTING IN AN ON GROUND LOSS OF CONTROL (GROUND LOOP) AND COLLAPSE OF THE LEFT MAIN LANDING GEAR.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Main gear collapsed, landing - roll
  - landing gear,tailwheel lock - failure,total (cause)
  - directional control - not possible, pilot in command
  - ground loop/swerve - encountered, pilot in command
  - landing gear,main gear shock absorbing strut - overload

## Analysis

THE PRIVATE PILOT WAS ON LANDING ROLL OUT WHEN THE AIRPLANE STARTED TURNING TO THE RIGHT. THE PILOT APPLIED LEFT RUDDER WITH NEGATIVE RESULTS. THE LEFT MAIN LANDING GEAR COLLAPSED AND THE AIRPLANE SUSTAINED SUBSTANTIAL DAMAGE. THE PILOT WAS NOT INJURED. EXAMINATION OF THE AIRPLANE BY AN A&P MECHANIC WITH INSPECTION AUTHORITY REVEALED THE TAIL WHEEL LOCK PAWL HAD FAILED.
