Circumstances:
Following an uneventful flight from Kaduna, the crew started the approach to Lagos-Murtala Muhammed Airport in poor weather conditions with heavy rain falls and strong winds. On short final, the wind changed to a tail component and became stronger. This caused the aircraft to land too far down the runway, about 1,000 metres past the runway threshold. On a wet runway surface, the aircraft was unable to stop within the remaining distance, overran, struck the concrete structure of a drainage ditch and came to rest 147 metres further, bursting into flames. 65 people were rescued while 15 passengers were killed. The aircraft was destroyed.
Probable cause:
It was determined that the accident was the consequence of the following factors:
- Poor quality in the organization of the meteorological support at Lagos airport, as a result of which the crew did not receive reliable information about the actual direction and force of the wind during the approach and landing procedure, which caused the aircraft to land too far down the runway;
- The presence of a layer of water on the runway, about which the crew was not informed prior to landing, which caused the aircraft to enter an aquaplaning mode and the loss of braking action efficiency;
- The failure of the crew to initiate a go-around procedure after he encountered poor weather conditions during the final stage of the approach and an erroneous estimation of the actual remaining length of the runway for the safe completion of the landing in case of heavy rainfall;
- Violation on part of the cabin crew requirements for the number and placement of flight attendants at landing, which led to unnoticed penetration of 15 passengers into the rear trunk and toilets after the plane crashed and their death in the event of a fire;
- Unsatisfactory organization of rescue operations at Lagos Airport.

Circumstances:
On approach to Lagos-Murtala Muhammed Airport, the crew encountered poor weather conditions with heavy rain falls and strong winds. The copilot was in command and the airplane was too high on approach so the captain took over controls and steeped the approach. Nevertheless, the aircraft was still too high over runway 19L threshold when it encountered severe downdraft. It nosed down and struck the runway surface nose gear first. It bounced, veered off runway to the left, rolled to the apron and eventually collided with a parked Fokker F27 Friendship 200MP of the Nigerian Air Force registered NAF908. Both aircraft were destroyed and one of the pilot on board the Twin Otter was killed, all eight other occupants were injured.
Probable cause:
It was determined that the crew lost control of the airplane upon landing after the wind suddenly changed from 270° at 10 knots to 360° at 50 knots. Also, windshear was suspected.

Circumstances:
While descending to Abuja-Nnamdi Azikiwe Airport, the crew encountered poor weather conditions with low clouds, heavy rain falls and moderate to severe turbulences. As the ILS was out of calibration, the crew decided to perform a VOR/DME approach but following a misunderstanding of the VOR location, the crew started the final approach prematurely. Too low, the aircraft struck the slope of a mountain located 12,2 km short of runway 22. Two people survived while three others were killed.
Probable cause:
Wrong approach configuration on part of the crew who initiated the descent prematurely, causing the aircraft to descend too low too early. Poor weather conditions were considered as contributing factors.

The aircraft stalled, entered a nose down attitude and crashed in a swampy area near the airport. All 159 occupants were killed, among them military personnels from Nigeria, Ghana, Tanzania, Uganda and Zimbabwe. Civilians were also among the passengers.
Probable cause:
It is believed that the engine failed because the fuel was contaminated with water and bacteria.

Circumstances:
The Dornier 228 originated from Lagos (LOS) at 07:00 UTC. Destination was Eket. Enroute, the captain briefed his copilot that the wind was northerly at 2 knots. He decided to use runway 19. He also briefed that they would descend to the Minimum Descent Altitude (MDA) of 500 ft. and if they did not have the field in sight by then, they would carry out a missed approach, maintain runway heading and climb to 1,500 ft. From Lagos, they were cruising at 11,000 ft. and started the descent at about 77 nm from Port Harcourt, which was close to Eket. On clearance to 5000 ft by Port Harcourt Approach Control, the crew called Eket Control who descended them to 3,500 ft. At about 10 nm from Eket the NDB frequency was picked up and the crew informed Eket that they were leaving 3500ft for 1500. When the aircraft came overhead the NDB they shot the approach. On the outbound leg of 195 they turned 45° for a right procedure turn and still maintaining 1500ft. Flap 1 was selected with the speed lever set in the high RPM position. With the runway inbound on track 105 magnetic, the landing gear was selected in the down position and the aircraft was descended to 500ft. After 90 seconds into the final approach on runway 01, the co-pilot called out "runway-in-sight" but the captain thought the aircraft was high, so he announced he was overshooting, whereas, while giving evidence the co-pilot said she advised the overshoot when the ADF needle swung. Another approach was attempted. They came back to the same runway 01 to maintain the MDA and the runway was sighted from about 2 miles out at 400 feet height. The co-pilot thought the aeroplane was high and called for a missed approach. Then another landing attempt was made for runway 19. At about between 600 - 700 feet height above the approach path, the captain instructed his co-pilot "when you see the field, give me flaps 2, I am going to land". As soon as the co-pilot sighted the runway at about 2nm out, she selected flap 2. The captain descended for the field and while they came over the threshold, the speed was between 95 and 98 knots. Height above threshold was 300ft; the co-pilot felt that the aeroplane was high, but she thought that at flap 2 the aircraft was committed to land. This time the First Officer did not warn the captain though she felt that the aircraft was high. The captain said that he descended fast from 300ft with the target aim of touching down at about the 6th centre line marking from the threshold. After the touchdown, the captain applied reverse pitch but no effect of the deceleration was felt. He then moved the throttle levers to the maximum reverse position, yet there was no deceleration effect. The next action was to go on the brakes while the aircraft still had the rolling speed of about 80 knots. The captain felt that only the right brakes were effective because-the aeroplane skidded to the right; when there was no directional control, the captain said that he then used the opposite rudder for control. The commander was still fighting with the directional control when the aeroplane overran the end of the paved way at about 40 knots with the brakes still applied. The airplane sustained damage to the wheels and propellers. The fuselage was buckled just forward of the left wing leading-edge and at the fuselage/wing rear attachment point. Also the right hand side of the fuselage had bucklings at the forward section.
Probable cause:
The accident was probably caused by the failure of the crew to accord due considerations and proper planning to the prevailing weather conditions. This resulted in a long landing, which extended into the unsuccessful braking action. The contributory factor to the accident was the emergence of communication breakdown and non display of professional airmanship within the cockpit area. The crux of that discord is the company's recommendation to seat a trainee officer on the left seat for at least 100 flying hours. This decision was not verbally resisted by the senior trainee captain but the aura existed everywhere and this led to the animosity within the cockpit.

Circumstances:
En route from Lagos to Kano, the crew was informed that a landing at Kano Airport was impossible due to poor weather conditions. The crew diverted to Sokoto but weather was also poor over there so ATC instructed the crew to follow a holding pattern as the airport was closed to traffic. After few dozen minutes, the crew informed ATC about fuel shortage, reduced his altitude and attempted an emergency landing. The aircraft landed in an open field located 6 km east from Sokoto Airport, lost its undercarriage and slid for few dozen meters before coming to rest. Four passengers were killed, 24 people were injured and 25 others escaped uninjured. The aircraft was destroyed.

Circumstances:
During the takeoff roll on runway 19L, at a speed of about 100 knots, the aircraft deviated from the centerline to the right. The pilot-in-command corrected with rudder but finally, the aircraft struck the right shoulder of the runway then veered off runway. It rolled in a grassy area and came to rest few dozen meters further. All 52 occupants evacuated safely while the aircraft was damaged beyond repair due to structural damages to the fuselage.
Probable cause:
It was determined that the right engine was not running properly during the takeoff roll, creating an asymmetric thrust and the aircraft to deviate from the centerline to the right. Investigations reported that the aircraft was subject to maintenance the days prior to the accident and modification were made to the fuel pump but nothing was entered in the airplane logbook. It was determined that the fuel pump overspeed governor had been set too low and a low power output at high TGT.

Circumstances:
Okada Air Flight OKJ307 originated from Lagos (LOS), at about 17:10 hours UTC en-route to Port-Harcourt (PHC). By 17:40 hours, at FL250, the crew established contact with Port Harcourt Tower and was cleared to the "PR" Radio Beacon. The 1700 hours weather report was passed onto the crew with the assurance not to expect any delay for an ILS approach to runway 21. At 75 nm from Port Harcourt, the aircraft was cleared down to FL90 and the crew reviewed their approach briefings. The First Officer was still flying when the airplane was further cleared to 2000 feet with the instructions to report when established on the localizer. At 700 feet, the Commander had the field-in-sight but the flying pilot had not. Then the Commander took over control from the First Officer. The captain requested the tower to increase approach lights intensity because of drizzling rain. The BAC 111 passed an area of heavy downpour. It entered a high sink rate and made a hard landing. The airplane bounced and made the second touchdown on its nose-wheel. The right nose wheel shattered instantaneously while the second nose wheel fractured at the hub. It rolled for about 90 metres and crumbled under the weight of the aircraft. When both wheels of the nose gear had broken away, the wheel axle made contact with runway to cut grooves onto the runway surface for about 25 metres before the nose strut finally gave way. The aircraft now scooped forward on the nose fuselage section and continued off the runway on to the left shoulder. On the shoulder, the aircraft ran into the wide trench which was covered up with loose soil and the impact severed off the right main gear from the attachment point. The aircraft eventually came to a stop 735 meters after touchdown.
Probable cause:
The probable cause of this accident is the poor handling of the controls at the critical movement of final approach and landing phases, probably due to the sudden loss of azimuth in the heavy downpour of rain. The contributory factor to the accident is the excavation and improper refilling of the outrageous trenches of wide dimensions along the length of runway 03/21.
