During the final approach to Moroni-Hahaya Airport following an uneventful flight from Dar es-Salaam, the crew failed to realize that his altitude was insufficient. On short final, the right wing struck approach lights. The captain increased engine power in an attempt to make a go-around when the airplane went to an excessive nose-up attitude, stalled and crashed into the sea near to the shore. None of the 16 occupants survived the crash.

Brand new, the aircraft was took over by ASA crew to be delivered to Atlanta, Georgia. He was cleared by the São José Tower controller to follow the 010° radial to the SJC VOR, and cross the VOR at 5,000 feet. Some time after takeoff São José Tower instructed the flight to climb to FL280 out of 5,000 feet and intercept the 352 radial of the SJC VOR. The flight crew failed to follow the instructions and continued at an altitude of 5,000 feet. In limited visibility due to low clouds, the airplane struck the slope of a mountain located in the Mantiqueira Mountain Range. The wreckage was found 700 feet below the summit. All five occupants were killed.

Embraer EMB-120 Brasília
Following an uneventful flight from Brussels, the crew contacted Bordeaux Approach at 15:01 and was vectored for an ILS approach to runway 23. Visibility was poor with low clouds at 100 feet and a runway visual range (RVR) of between 650 and 350 metres. Flight 1919 crossed the KERAG beacon, the initial approach fix (IAF) at an altitude of FL144, at 15:04:40. Cloud base was still around 100 feet so the crew requested to enter a holding pattern to the south of the airport. The weather conditions slightly improved during the next few minutes and Bordeaux Approach reported a cloud base at 160 feet. Flight 1919 had not reached the holding pattern yet and the pilot decided to attempt to rejoin the ILS. At 15:06:38 the flight was cleared direct to the BD beacon and to descend down to 2000 feet. At the BD beacon, the flight was cleared for final approach and instructed to contact Bordeaux Tower. The airplane had overshot the centreline and was slightly right on the glidepath. Bordeaux Tower then instructed the flight to report over the Outer Marker, which was acknowledged by the captain. After crossing the Outer Marker, the airplane was still not properly established on the ILS. The airplane descended below the glideslope with the crew hurriedly deploying flaps and landing gear. The captain did not contact Bordeaux Tower as requested. Instead he took over control of the airplane, attempting to continue the approach. Both crew members had very little time to adapt to their new roles as the airplane was descending below the glide slope. The descent continued until the aircraft struck tree tops and crashed in the Eysines forrest, about 5 km short of runway. The aircraft was totally destroyed and all 16 occupants were killed.

Witnesses reported that the airplane suddenly turned or rolled left until the wings were perpendicular to the ground. The airplane then fell in a nose-down attitude. Examination of the left propeller components indicated a blade angle of about 3°, while the left propeller control unit (pcu) ballscrew position was consistent with a commanded blade angle of 79.2°. Extreme wear on the pcu quill spline teeth, which normally engaged the titanium-nitrided splines of the propeller transfer tube, was found. The titanium-nitrided surface was much harder and rougher than the nitrided surface of the quill. Therefore, the transfer tube splines acted like a file and caused abnormal wear of the gear teeth on the quill. Wear of the quill was not considered during the certification of the propeller system. The aircraft was totally destroyed upon impact and all 23 occupants were killed, among them John Goodwin Tower, Senator of Texas and the astronaut Manley Sonny Carter.
