The flight was carrying 26 passengers and 4 crew. Among the passengers were 7 French nationals, 2 Lebanese and a German. Shortly after takeoff from Libreville the crew reported problems with the aircraft. A failure of the oil pressure on the No.2 engine occurred, causing the crew to turn back.
While returning the crew tried to extend the aircraft's landing gear, however it did not do so, due to problems with the hydraulics. Witnesses on the ground stated that the aircraft was operating with only one engine. Flight 221 then nose-dived into the sea .
