Flight Details
A cargo aircraft departed Luanda for Menongue with four crew members and a load of fuel drums. While cruising, one of the engines failed. The crew managed to continue the flight and landed normally at Menongue Airport.
Subsequent Return Flight
After landing, the crew decided to fly the aircraft back to Luanda on three engines for maintenance, rather than waiting for a technical crew to arrive the next day. Shortly after takeoff from Menongue, while climbing, a second engine failed. The aircraft stalled and crashed.
Outcome
All four crew members were killed in the crash.
Probable Cause
The official investigation determined that the probable cause of the accident was engine failure, but the reason for the failure remains unknown.
