## Sequence of events

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

- Airframe/component/system failure/malfunction, standing - engine(s) operating
  - landing gear,emergency brake system - inoperative (cause)
  - landing gear,normal brake system - worn (cause)
- On ground/water collision with object, taxi
  - fuel system,cap - loose (contributing factor)
  - aircraft preflight - inadequate, pilot in command (contributing factor)
  - aircraft unattended/engine(s) running - intentional, pilot in command (cause)

## Analysis

THE PILOT WAS PREPARING TO TAXI WHEN HE NOTICED A LOOSE FUEL CAP ON THE ACFT'S LEFT WING. HE SET THE PARKING BRAKE, EXITED THE ACFT WITH BOTH ENGINES OPERATING, PLACED A CHOCK ON THE RIGHT WHEEL AND WAS SECURING THE LOOSE FUEL CAP WHEN THE ACFT STARTED TO MOVE. HE TRIED TO HOLD THE ACFT BY THE WING BUT IT CONTINUED TO TURN AND STRUCK A PARKED COMMANDER 690C, N155WP. THE PILOT STATED THAT PRIOR TO EXITING THE COCKPIT HE ASKED THE FRONT SEAT PASSENGER TO HOLD THE BRAKES IN CASE THE ACFT MOVED. THE PASSENGER WAS FAMILIAR WITH THE BRAKES. THE PASSENGERS ATTEMPTS TO STOP THE ACFT WERE NOT SUCCESSFUL. POST ACCIDENT EXAMINATION DISCLOSED THAT THE PARKING BRAKE VALVE DID NOT HOLD PRESSURE AND THE LEFT BRAKE LININGS WERE AT MINIMUM THICKNESS.
