## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - weather condition - crosswind (contributing factor)
  - landing gear,tailwheel assembly - jammed (cause)
  - directional control - not maintained, pilot in command
  - ground loop/swerve - uncontrolled, pilot in command

## Analysis

THE PLT STATED THAT DURING A WHEEL LANDING, THE ACFT BOUNCED, BUT NOT HARD. HE REPORTED THAT HE APPLIED SUFFICIENT POWER TO RECOVER & MADE A SMOOTH, 3-POINT TOUCHDOWN, THEN THE ACFT BEGAN A GRADUAL SKIDDING TURN TO THE RIGHT. THE PLT CORRECTED WITH LEFT RUDDER, BUT IT HAD NO EFFECT. HE SAID THAT HE THEN APPLIED HARD LEFT RUDDER & BRAKE; HOWEVER, THE ACFT CONTINUED THE RIGHT SWERVE & THE LEFT MAIN GEAR COLLAPSED. AN EXAM OF THE ACFT REVEALED THE LEFT TAILWHEEL STEERING CABLE HAD COME OFF OF A PULLEY & HAD JAMMED BETWEEN THE PULLEY & A BRACKET. THERE WAS EVIDENCE THAT THE CABLE MAY HAVE BEEN LOOSE OR OUT-OF-RIG. HOWEVER, THE REASON FOR THE CABLE TO COME OFF OF THE PULLEY WAS NOT VERIFIED.
