Boeing 737-200

The Boeing 737 completed a flight from Lagos (LOS) through Abuja (ABV) to Kaduna (KAD) and was parked for over an hour. At 14:45 UTC, the Chief Pilot of Chanchangi Airline approached the Air Traffic Controller stating that he would like to fly around the circuit for a training flight. He was told that the visibility was 600 meters which was below the landing minima and was then advised against it. The pilot then suggested that he would carry out a "Rejected Takeoff" training. Additional persons boarded the flight to witness the exercise. At 15:37 UTC the pilot requested a take off clearance which was granted, and was directed to proceed to the holding point of runway 05. The prevailing visibility was 600 meters and the wind was 090 at 10 knots. Four rejected take off training runs were carried out within an interval of twelve minutes. In the conditions at Kaduna, a single exercise of a rejected take off would have required a cooling period of at least ten minutes. At the end of the fourth run, the left main landing gear number 2 brake unit had started to burn. The pilot steered the airplane off the runway into the last taxiway. Fifty meters from the runway 05 threshold the left inner wheel failed and leaving a molten rubber footprint on the taxiway and at the same time the hydraulic fluid of the brake units started to spill tracing an oily track along. Pieces of broken wheel rim were randomly shed for a distance of 150 meters when the rims appeared to undergo a major collapse. The footprint of the two left wheels became more pronounced for a distance of 120 meters when there was a positive turn to the left indicating a total failure in roll from the left wheel assembly. The zigzag motion continued for about 699 meters until the aircraft could no longer be easily moved and the pilot called for the fire trucks. The aircraft burnt to ashes on the spot.

During the takeoff roll from Najran Airport runway 06/24, at a speed of 95 knots, the right engine thrust suddenly increased. Few seconds later, at a speed of 120 knots, the exhaust gas temperature warning came on in the cockpit panel. The captain decided to abort and initiated an emergency landing procedure. Speed brakes were deployed but the thrust reversers could not be activated. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage and right engine before coming to rest. All 85 occupants evacuated safely.

During the takeoff roll on runway 23 at Douala Airport, at a speed of 110 knots, the crew noted a loud bang and decided to abort. The crew initiated an emergency braking procedure but the aircraft was unable to stop within the remaining distance. It overran, lost its undercarriage and both engines before coming to rest 130 metres further, bursting into flames. All 114 occupants were evacuated, among them 20 were slightly injured. The aircraft was destroyed.

The aircraft departed Belém-Val de Cans Airport on a flight to Brasília with intermediate stops in Marabá and Carajás, carrying 48 passengers and a crew of six. The approach to Carajás-Parauapebas Airport was completed in poor weather conditions with rain falls, clouds down to 120 metres and a limited visibility due to rain and fog. On final the aircraft was unstable and landed hard on runway 10. On touchdown, the right main gear was torn off and the aircraft went out of control. It veered off runway to the right, collided with trees and eventually came to rest in a wooded area. The copilot was killed as the right side of the cockpit was destroyed upon impact. Ten other people were injured and 43 escaped unhurt. The aircraft was destroyed.

During the takeoff roll, the captain noted a difference in the engine N1 readings. He decided to abandon the takeoff procedure and initiated an emergency braking manoeuvre. Unable to stop within the remaining distance, the aircraft overran, lost its nose gear and came to rest 40 metres further. All 106 occupants escaped uninjured and the aircraft was damaged beyond repair.

A United States Air Force Boeing T-43A (USAF designation for the Boeing 737-200) was destroyed after impacting a hillside during an NDB approach to Dubrovnik Airport, Croatia. All 35 on board were killed. The aircraft was engaged in a mission to fly United States Secretary of Commerce Ron Brown and a delegation of industry executives around the region for visits. The party was to be flown from Zagreb to Tuzla and Dubrovnik before returning to Zagreb. Operating with a call sign of IFO21, the accident aircraft departed Zagreb at 06:24 hours. The crew landed at Tuzla at 07:15 after an uneventful flight. The passengers deplaned, and the aircraft was then repositioned to Split because of insufficient ramp space at Tuzla to park the aircraft for the duration of the visit. At 12:47, the aircraft landed at Tuzla, where the passengers reboarded. The accident flight departed Tuzla for Dubrovnik at 13:55. After crossing Split at 14:34 the flight was cleared to descend from FL210 to FL140. Further descent clearance was given to FL100. After the aircraft reached FL100 at 14:45, south of Split VOR, Zagreb Center transferred control to Dubrovnik Approach/Tower. The controller cleared IFO21 direct to the Kolocep (KLP) NDB. After opposite-direction traffic had been cleared, IFO21 was cleared to descend to 5000 feet. At 14:52, the crew told Dubrovnik Approach/Tower that they were 16 NM from the airport. They were cleared to descend to 4,000 feet and told to report crossing the KLP beacon. At 14:53, the aircraft crossed KLP, which was the Final Approach Fix (FAF), at 4100 feet and began the approach without approach clearance from Dubrovnik Tower. At that point the aircraft was slightly high and fast and not completely configured for the approach, as it should have been. At 14:54, the copilot of IFO21 called Dubrovnik Approach/Tower and said, "We’re inside the locator, inbound." IFO21 was then cleared for the NDB approach to runway 12. The aircraft tracked a course of 110 degrees after crossing KLP, instead of tracking the published course of 119 degrees. The aircraft maintained this track from KLP to the point of impact. The accident aircraft descended to 2200 feet which was consistent with the published minimum descent altitude of 2,150 feet. At 14:57, the aircraft impacted a rocky mountainside approximately 1.7 NM to the left (northeast) of the extended runway centerline and 1.8 NM north of the approach end of runway 12 at Dubrovnik Airport.

The approach to Arequipa-Rodríguez Ballón Airport was completed by night and poor weather conditions with heavy rain falls. On final approach, the crew failed to realize his altitude was insufficient when the aircraft struck a hill and crashed 6,3 km from runway 09 threshold. The aircraft disintegrated on impact and all 123 occupants were killed.
