Abuja

The airplane departed Abuja-Nnamdi Azikiwe Airport at 1941LT on a charter flight (IB500) to Ibadan, carrying seven passengers and three crew members. At 2013LT, the crew was cleared to land on runway 22 and continued the approach. On short final, the airplane impacted the first row of approach lights on the approach path, then touched down first with the right main landing gear, about 220 metres short of the threshold of the runway, and in the grass verge, followed shortly by the left main and nose landing gears respectively. The aircraft continued towards the paved area of the runway, impacting several other rows of approach lights along its path. A total of six impact points were observed. Subsequently, the aircraft entered the paved area and veered right of the centerline, runway 22. At about 156 metres from the threshold, the aircraft crossed the right runway shoulder and continued into the grass verge for a distance of about 184 metres before coming to a stop, partially impeded by vegetation. Number one tyre was found deflated and the nose landing gear collapsed. All 10 occupants disembarked safely.
The below preliminary report was quickly published by NSIB.

After takeoff from Abuja-Nnamdi Azikiwe Airport, while climbing, the crew informed ATC about an engine failure and was cleared for an immediate return. On final approach to runway 22, the aircraft went out of control and crashed in an open field, bursting into flames. The aircraft was destroyed and all 7 occupants were killed, among them two pilots, four ATOS specialists (Airborne Tactical Observation System) and one technician.

On 25th January 2018 at 14:28 h, a Gulfstream 200 (G200) aircraft with nationality and registration marks 5N-BTF operated by Nestoil Plc, departed Murtala Mohammed International Airport, Lagos (DNMM) as a charter flight to Nnamdi Azikiwe International Airport, Abuja (DNAA) on an Instrument Flight Rules (IFR) flight plan. Onboard were four passengers and three flight crew members. The Pilot in command (PIC) was the Pilot Monitoring (PM) and the Co-pilot was the Pilot Flying (PF). The departure, cruise and approach to Nnamdi Azikiwe International Airport were normal. At 14:45 h, 5N-BTF contacted Abuja radar and was subsequently cleared for Radar vectors ILS approach Runway 22. Abuja Airport Automatic Terminal Information Service (ATIS) Papa for time 14:20 h was monitored as follows; “Main landing runway 22, wind 110/07 kt, Visibility 3,500 m in Haze, No Significant Clouds, Temperature/Dew point 33/- 01°C, QNH 1010 hPa, Trend No Significant Change, End of Information Papa”. At 15:17 h, 5N-BTF reported 4 NM on Instrument approach (ILS) and was requested to report 2 NM because there was a preceding aircraft (Gulfstream 5) on landing roll. Thereafter, 5N-BTF was cleared to land runway 22 with reported wind of 070°/07 kt. At 15:18 h, the aircraft touched down slightly left of the runway centre line. According to the PF, in the process of controlling the aircraft to the centre line, the aircraft skidded left and right and eventually went partly off the runway to the right where it came to a stop. In his report, the PM stated that on touchdown, he noticed the aircraft oscillating left and right as brakes were applied. The oscillation continued to increase and [the aircraft] eventually went off the runway to the right where the aircraft came to a stop, partially on the runway. During the post-crash inspection, the investigation determined that the skid marks on the runway indicated that the aircraft steered in an S-pattern continuously with increasing amplitude, down the runway. On the last right turn, the aircraft exited the right shoulderof the runway, the right main wheel went into the grass and on the final left turn, the right main landing gear strut detached from its main attachment point after which the aircraft finally came to a complete stop on a magnetic heading of 160°. The ATC immediately notified the Aircraft Rescue and Fire Fighting Services (ARFFS), Approach Radar Control, and other relevant agencies about the occurrence. All persons on board disembarked with no injuries. Instrument Meteorological Conditions (IMC) prevailed at the time of the occurrence. The serious incident occcurred in daylight.

Shortly after takeoff from the Kaduna Military Airfield, while climbing, the aircraft went out of control and crashed into a house located in the Ribadu Cantonment, bursting into flames. All seven occupants (two pilots, two engineers and three passengers) were killed.

On 11th June, 2015, at about 18:25 h, an HS-125-800XP aircraft with nationality and registration marks N497AG, operated by SWAT Technology Limited departed Nnamdi Azikiwe International Airport, Abuja (DNAA) for Port Harcourt International Airport (DNPO) as a charter flight on an Instrument Flight Rule (IFR) flight plan. There were five persons on board inclusive of three flight crew and two passengers. The Captain was the Pilot Flying while the Co-pilot was the Pilot Monitoring. At 18:48 h, N497AG established contact with Lagos and Port Harcourt Air Traffic Control (ATC) units cruising at Flight Level (FL) 280. At 18:55 h, the aircraft was released by Lagos to continue with Port Harcourt. Port Harcourt cleared N497AG for descent to FL210. At 19:13 h, the crew reported field in sight at 6 nautical miles to touch down to the Tower Controller (TC). TC then cleared the aircraft to land with caution “runway surface wet”. The crew experienced light rain at about 1.3 nautical miles to touch down with runway lights ON for the ILS approach. At about 1,000 ft after the extension of landing gears, the PM remarked ‘Okay...I got a little rain on the windshield’ and the PF responded, ‘We don’t have wipers sir... (Laugh) Na wa o (Na wa o – local parlance, - pidgin, for expression of surprise). From the CVR, at Decision Height, the PM called out ‘minimums’ while the PF called back ‘landing’ as his intention. The PM reported that the runway edge lights were visible on the left side. On the right side, it was missing to a large extent and only appeared for about a quarter of the way from the runway 03 end. The PM observed that the aircraft was slightly to the left of the “centreline” and pointed out “right, right, more right.” The PM further stated that at 50 ft, the PF retarded power and turned to the left. At 40 ft, the PM cautioned the PF to ‘keep light in sight don’t go to the left’. At 20 ft, the PM again said, ‘keep on the right’. PF replied, ‘Are you sure that’s not the centre line?’. At 19:16 h, the aircraft touched down with left main wheel in the grass and the right main wheel on the runway but was steered back onto the runway. The PF stated, “...but just on touchdown the right-hand lights were out, and in a bid to line up with the lights we veered off the runway to the left”. The nose wheel landing gear collapsed, and the aircraft stopped on the runway. The engines were shut down and all persons on board disembarked without any injury. From the CVR recordings, the PF told the PM that he mistook the brightly illuminated left runway edge lights for the runway centreline and apologized for the error of judgement for which the PM responded ‘I told you’. The aircraft was towed out of the runway and parked at GAT Apron at 21:50 h. The accident occurred at night in light rain.

Following an uneventful cargo flight from Jeddah, the crew completed the approach and landing procedures on runway 04 at Abuja-Nnamdi Azikiwe Airport. During the landing roll, the aircraft overran the displaced threshold then veered to the right and veered off runway. While contacting a grassy area, the aircraft collided with several parked excavator equipment and trucks. The aircraft came to a halt and was severely damaged to both wings and engines. All six occupants escaped uninjured while the aircraft was damaged beyond repair.

On 3rd June, 2012 at about 1545:00hrs, 5N-RAM, a Boeing MD-83, a domestic scheduled commercial flight, operated by Dana Airlines (Nig.) Limited as flight 0992 (DANACO 0992), crashed into a densely populated area of Iju-Ishaga, a suburb of Lagos, following engine number 1 loss of power seventeen minutes into the flight and engine number 2 loss of power while on final approach to Murtala Muhammed Airport Lagos, Nigeria. Visual Meteorological Conditions prevailed at the time and the airplane was on an instrument flight plan. All 153 persons onboard the airplane, including the six crew were fatally injured. There were also six confirmed ground fatalities. The airplane was destroyed. There was post impact fire. The flight originated at Abuja (ABV) and the destination was Lagos (LOS). The airplane was on the fourth flight segment of the day, consisting of two round-trips between Lagos and Abuja. The accident occurred during the return leg of the second trip. DANACO 0992 was on final approach to runway 18R at LOS when the crew declared a Mayday call “Dual Engine Failure – negative response from the throttles.” According to records, the flight arrived ABV as Dana Air flight 0993 at about 1350:00hrs and routine turn-around activities were carried out. DANACO 0992 initiated engine start up at 1436:00hrs. Abuja Control Tower cleared the aircraft to taxi to the holding point of runway 04. En-route ATC clearance was passed on to DANACO 0992 on approaching holding point of runway 04. According to the ATC ground recorder transcript, the aircraft was cleared to line-up on runway 04 and wait, but the crew requested for some time before lining-up. DANACO 0992 was airborne at 1458:00hrs after reporting a fuel endurance of 3 hours 30 minutes. The aircraft made contact with Lagos Area Control Centre at 1518:00hrs and reported 1545:00hrs as the estimated time of arrival at LOS at cruising altitude of 26,000 ft. The Cockpit Voice Recorder (CVR) retained about 30 minutes 53 seconds of the flight and started recording at 1513:44hrs by which time the Captain and First Officer (F/O) were in a discussion of a non-normal condition regarding the correlation between the engine throttle setting and an engine power indication. However, they did not voice concerns then that the condition would affect the continuation of the flight. The flight crew continued to monitor the condition and became increasingly concerned as the flight transitioned through the initial descent from cruise altitude at 1522:00hrs and the subsequent approach phase. DANACO 0992 reported passing 18,100ft and 7,700ft, at 1530:00hrs and 1540:00hrs respectively. After receiving radar vectors in heading and altitude from the Controller, the aircraft was issued the final heading to intercept the final approach course for runway 18R. According to CVR transcript, at 1527:30hrs the F/O advised the Captain to use runway 18R for landing and the request was made at 1531:49hrs and subsequently approved by the Radar Controller. The crew accordingly changed the decision height to correspond with runway 18R. At 1531:12hrs, the crew confirmed that there was no throttle response on the left engine and subsequently the Captain took over control as Pilot Flying (PF) at 1531:27hrs. The flight was however continued towards Lagos with no declaration of any distress message. With the confirmation of throttle response on the right engine, the engine anti-ice, ignition and bleed-air were all switched off. At 1532:05hrs, the crew observed the loss of thrust in No.1 Engine of the aircraft. During the period between 1537:00hrs and 1541:00hrs, the flight crew engaged in prelanding tasks including deployment of the slats, and extension of the flaps and landing gears. At 1541:46hrs the First Officer inquired, "both engines coming up?" and the Captain replied “negative” at 1541:48hrs. The flight crew subsequently discussed and agreed to declare an emergency. At 1542:10hrs, DANACO 0992 radioed an emergency distress call indicating "dual engine failure . . . negative response from throttle." At 1542:35hrs, the flight crew lowered the flaps further and continued with the approach and discussed landing alternatively on runway 18L. At 1542:45hrs, the Captain reported the runway in sight and instructed the F/O to retract the flaps and four seconds later to retract the landing gears. At 1543:27hrs, the Captain informed the F/O, "we just lost everything, we lost an engine. I lost both engines". During the next 25 seconds until the end of the CVR recording, the flight crew attempted to recover engine power without reference to any Checklist. The airplane crashed into a densely populated residential area about 5.8 miles north of LOS. The airplane wreckage was approximately on the extended centreline of runway 18R, with the main wreckage concentrated at N 06o 40.310’ E 003o 18.837' coordinates, with elevation of 177ft. During the impact sequence, the airplane struck an uncompleted building, two trees and three other buildings. The wreckage was confined in a small area, with the separated tail section and engines located at the beginning of the debris trail. The airplane was mostly consumed by post crash fire. The tail section, both engines and portions of both wings representing only about 15% of the airplane, were recovered from the accident site for further examination.

After landing at Port Harcourt Airport, the aircraft skidded then veered off runway and came to rest. All 52 occupants were rescued, among them 10 were slightly injured. The aircraft was damaged beyond repair. All passengers were members of the intervention group taking part to a disaster response operation.

The B737-200 aircraft which night-stopped at Calabar on Saturday the 28th of October, 2006, departed for Lagos in the morning of the 29th of October, 2006, and landed in Lagos at 0825 hrs. While on ground in Lagos, it uplifted some fuel. There was only cabin crew change. The aircraft departed Lagos on scheduled passenger service as ADK 063 at 0929 hrs and landed in Abuja at 1020 hrs. The aircraft uplifted 5000 litres of fuel and had 11000kg fuel for departure as ADK 053, a scheduled service to Sokoto. After boarding, it started raining and this compelled the crew to close the aircraft doors. Shortly after the rain had subsided, the doors were opened for the ground personnel to disembark. The crew then requested for start-up clearance. At 1115 hrs the aircraft was given a start up clearance for Sokoto. At 1121 hrs, the aircraft was given taxi clearance to holding position Runway 22. The pilot immediately requested for the wind, which was given as “210 variable at 8 kts”. Shortly after, the Control Tower transmitted the wind as south-westerly at 15 kts. While taxiing, the control tower advised Flight ADK 053 of gusty wind. The wind was initially given as 35 kts and then changed to 28 kts within 1 minute. At 1125 hrs while the aircraft was at the holding point, the crew was again advised of South-Westerly wind at 15 kts. At this juncture, the pilot of Virgin Nigeria 042 was heard on the radio saying “it looks like 35 kts to me” and then stated that he was going to wait for improvement in the weather, which he did. Thereafter, the ADK 053 crew requested for takeoff clearance and was cleared with right turn-out on course. Flight ADK 053 was airborne at 1129 hrs and was transferred to the Approach Control on 119.8MHZ but there was no acknowledgement from the crew. After three unsuccessful attempts to contact the aircraft, the Tower advised the Approach Control to call ADK 053. Other aircraft on the apron (Virgin Nigeria 042 and Trade Wings 2401), which were on that frequency were also asked to assist in contacting the aircraft but all attempts were unsuccessful. Kano and Lagos Area Controls were requested to contact ADK 053, but there was no response from the aircraft. Abuja Flight Communication Centre was then advised to inform National Emergency Management Agency (NEMA) in Kano about the loss of contact with the aircraft. At 1138 hrs, Flight Communication Centre called the Control Tower that someone came from a nearby village (Tungar Madaki) near the radar site and reported that a plane had crashed in their village. A search party from the airport was dispatched and they found and confirmed that the plane had crashed shortly after takeoff. The accident resulted in 96 fatalities out of 105 persons on board (POB). The accident occured at latitude N 08 59.691’ longitude E 007 14.772’ on an elevation of 1123 ft (ASL). The time of the accident was 1130 hrs during daylight and in rain.

The twin engine aircraft departed Abuja on a flight to Obudu, carrying 15 passengers and a crew of three. The pilots started the descent in poor weather conditions when the aircraft impacted hilly terrain near Vande Ikya, about 29 km northwest of Obudu. Five occupants were injured while 13 others were killed, among them several high ranking officers who were flying to Obudu to proceed to an inspection of the military equipments. At the time of the accident, the visibility was poor due to low ceiling.
