Incident Overview
After departing from Addis Ababa-Bole Airport, the flight crew encountered difficulties with the landing gear during the initial climb. The undercarriage could not be retracted, prompting the decision to return to the airport for a precautionary landing. The subsequent touchdown was uneventful, but the aircraft was unable to stop within the remaining runway distance due to a malfunction of the hydraulic systems.
Sequence of Events
As the aircraft rolled down the runway, the loss of hydraulic function prevented normal braking and steering. The airplane overran the end of the runway, collapsing the landing gear and coming to rest off the paved surface. All on board were accounted for, and emergency crews responded to the scene.
Evacuation and Injuries
All 76 occupants successfully evacuated the aircraft. Six passengers sustained minor injuries during the evacuation. No serious injuries or fatalities were reported.
Damage
The aircraft sustained substantial damage and was declared beyond economical repair.
Probable Cause
Official investigation findings attributed the accident to a failure of the hydraulic systems for unknown reasons.
