Incident Overview
The aircraft was en route to Madras when the primary hydraulic system failed. The flight crew did not correctly identify the nature of the failure. After touchdown at Madras Airport, the brake systems were found to be partially inoperative.
Sequence of Events
Unable to stop within the remaining runway distance, the airplane overran the end of the runway. During the overrun, it struck obstacles, which caused the loss of the undercarriage. The aircraft eventually came to a halt. All 31 occupants on board evacuated the aircraft safely.
Damage Assessment
The aircraft sustained structural damage that rendered it beyond economical repair. It was subsequently considered as damaged beyond repair.
Probable Cause
The official investigation determined the probable cause to be failure of the primary hydraulic system in flight due to an incorrectly installed gasket.
