Circumstances:
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.
Probable cause:
The accident was the consequence of a black hole effect disorientation causing low-level manoeuvre into grass verge.
The following contributing factors were identified:
- Most of the runway 21 right edge lights were unserviceable at landing time.
- Inadequate Crew Resource Management during approach.

Circumstances:
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.
Probable cause:
The accident resulted as the crew was not updated on the information available on the reduced runway length.
The following contributing factors were identified:
1. Lack of briefing by Saudia dispatcher during pre-flight.
2. Runway status was missing from Abuja ATIS information.
3. Ineffective communication between crew and ATC on short finals.
4. The runway markings and lighting not depicting the displaced threshold.
5. The entire runway lighting was ON beyond the displaced threshold.

Circumstances:
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.
Probable cause:
Probable Causal Factors:
1. Engine number 1 lost power seventeen minutes into the flight, and thereafter on final approach, Engine number 2 lost power and failed to respond to throttle movement on demand for increased power to sustain the aircraft in its flight configuration.
2. The inappropriate omission of the use of the Checklist, and the crew’s inability to appreciate the severity of the power-related problem, and their subsequent failure to land at the nearest suitable airfield.
3. Lack of situation awareness, inappropriate decision making, and poor airmanship.

Tear down of the engines showed that the no.1 engine was overhauled in the U.S in August 2011 and was not in compliance with Service Bulletin SB 6452. Both engines had primary and secondary fuel manifold assemblies fractured, cracked, bent, twisted or pinched which led to fuel leaks, fuel discharge to bypass duct, loss of engine thrust and obvious failure of engine responding to
throttle movement. This condition was similar to the no.1 engine of a different Dana Air MD-80, 5N-SAI, that was involved in an incident in October 2013 when the aircraft returned to the departure airport with the engine not responding th throttle movements. This engine also was not in compliance with Service Bulletin SB 6452. This bulletin was issued in 2003 and called for the installation of new secondary fuel manifold assemblies, incorporating tubes fabricated from new material which has a fatigue life that was approximately 2 times greater than the previous tube material.

Circumstances:
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.
Probable cause:
Causal Factor:
The pilot’s decision to take-off in known adverse weather conditions and failure to execute the proper windshear recovery procedure resulted in operating the aircraft outside the safe flight regime, causing the aircraft to stall very close to the ground from which recovery was not possible.
Contributory Factors:
1) Inability of the flight crew to apply windshear recovery procedures and the use of inappropriate equipment for windshear recovery procedure during simulator recurrency. Lack of company Standard Operating Procedures (SOP) for flight operations in adverse weather conditions.
2) The coordination of responsibilities between the pilot-flying (PF) and pilot not flying(PNF) during their encounter with adverse weather situation was inconsistent with Standard Operating Procedures (SOP) for the duties of the pilot-flying (PF) and pilot not flying(PNF) resulting in the inadequate control of the aircraft.

Circumstances:
The aircraft with call sign OSL 1 145 which departed Abuja at 1225 hrs UTC (1.25 pm local time) with endurance of 2 hours 40 minutes was on a scheduled passenger flight enroute Port Harcourt with 110 Persons on Board (103 Passengers and 7 Crew) and the flight continued normally. At 1241 hours UTC, the aircraft cruising at FL240 (24,000ft) Above Sea Level (ASL) got in contact with Port Harcourt Approach Control. The Approach control gave the OSL 1145 in - bound clearance to expect no delay on ILS Approach to runway 21, QNH of 1008 and temperature of 33° C. At about 1242 hours UTC (1.42pm local), the Approach controller passed the 1230 hours UTC weather report to the aircraft as follows: Wind - 260° /02kts Visibility - 12km Weather - Nil Cloud - BKN 420m, few CB (N-SE) at 690m QNH - 1008HPA Temperature - 33° C. About 1250 hours UTC (1.50 pm local), the aircraft, which was 90 nautical miles to the station, contacted Approach Control for initial descent clearance and was cleared down to FL 160. The aircraft continued its descent until about 1300 hours UTC (2.00 pm local) when the crew asked Approach Control whether it was raining over the station to which the controller reported negative rain but scattered CB and the crew acknowledged. At 1304 hours UTC, the crew reported established on the glide and the localizer at 8 nautical miles to touch down. Then the Approach controller informed the aircraft of precipitation approaching the station from the direction of runway 21 and passed the aircraft to Tower for landing instructions. At 1305 hours UTC, the aircraft contacted Tower and reported established on glide and localizer at 6 nautical miles to touch down. The controller then cleared the airplane to land on runway 21 but to exercise caution as the runway surface was slightly wet and the pilot acknowledged. At about 1308 hours UTC, the aircraft made impact with the grass strip between runway 21 and taxiway i.e. 70m to the left of the runway edge, and 540m from the runway 21 threshold. At about 60m from the first impact, the aircraft tail section impacted heavily with a concrete drainage culvert. The airplane then disintegrated and caught fire along its path spanning over 790m. The cockpit section and the forward fuselage were found at about 330m from the rest of the wreckage further down on the taxiway creating a total wreckage trail of 1 120m. Fire and rescue operations were carried out after which 7 survivors and 103 bodies were recovered. Five of the survivors died later in the hospital. The accident occurred in `Instrument Meteorological Conditions' (IMC) during the day.
Probable cause:
The probable cause of the accident was the crew's decision to continue the approach beyond the Decision Altitude without having the runway and/or airport in sight.
The contributory factors were:
- The crew's delayed decision to carry out a missed approach and the application of improper procedure while executing the go-around.
- The aircraft encountered adverse weather conditions with the ingredients of wind shear activity on approach.
- The reducing visibility in thunderstorm and rain as at the time the aircraft came in to land was also a contributory factor to the accident. And the fact the airfield lightings were not on may also have impaired the pilot from sighting the runway.
- Another contributory factor was the fact that the aircraft had an impact with the exposed drainage concrete culvert which led to its disintegration and subsequent tire outbreak.
