What happened
During the initial climb phase following departure from Bata Airport, the crew of the aircraft declared an emergency and attempted to perform a return to the airfield. Air traffic control indicated that a runway landing was obstructed by another aircraft present on the strip at the time.
While attempting the return maneuver, the flight crew lost control of the aircraft type (unspecified model). The plane subsequently crashed into the ocean a few hundred meters away from the coast. Search efforts located the wreckage in shallow waters. There were 22 fatalities and no survivors among the occupants.
Findings
Preliminary observations indicate that the right engine failed during the initial climb, rendering it non-functional prior to the impact with the water.
