Accident Details
A charter flight departed Jakarta-Halim Perdanakusuma Airport bound for Singapore, transporting expatriates leaving Indonesia due to political unrest. The aircraft was on approach to Singapore-Seletar Airport when the copilot performed the landing checklist but did not arm the lift dumper. This prevented the antiskid system from being used.
Sequence of Events
After touching down on a wet runway, the crew initiated braking. However, the braking action was insufficient. The captain then applied the emergency brakes, a procedure not recommended when hydroplaning is suspected. Unable to stop within the remaining runway distance, the aircraft overran the end of the runway.
Damage and Occupants
The overrun resulted in the separation of the left wing and left main landing gear before the aircraft came to rest. All 80 occupants exited without injury. The aircraft was deemed a write-off.
