NTSB narrative
ACCORDING TO THE PILOT, ONE SIDE OF THE BRACKET THAT HOLDS THE PARKING BRAKE HANDLE IN THE ON POSITION BROKE AND PARTLY RELEASED THE BRAKES. THE AIRPLANE TAXIED AWAY WHILE THE PILOT WAS PUTTING A COMPRESSED AIR TANK IN HIS TRUCK. THE AIRPLANE STRUCK A PARKED AIRPLANE BEFORE THE PILOT STOPPED THE TAXIING AIRPLANE WITH A ROPE. HE WAS NOT USING WHEEL CHOCKS.
Probable cause
THE PARKING BRAKE FAILURE DUE TO A BROKEN BRACKET; INTENTIONALLY LEAVING THE AIRPLANE UNATTENDED WITH THE ENGINE RUNNING BY THE PILOT-IN-COMMAND; AND THE IMPROPER PLANNING AND DECISION OF THE PILOT-IN-COMMAND BY NOT USING WHEEL CHOCKS.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
