Accra-Kotoka

On 29th July, 2017 at about 0905hrs, an Antonov aircraft Model AN-74TK-100, flight CVK7087, registration UR-CKC, owned by SWIFT SOLUTION FZC and operated by CAVOK Airlines LLC was departing Sao Tome International Airport to Kotoka International Airport, Accra, for positioning with six crew on board. The flight was on an Instrument Flight Rule (IFR) flight plan and Visual Meteorological Conditions prevailed. The aircraft exited runway 29 during a rejected take off. The Flight Navigator sustained an injury and the aircraft was destroyed. On 28th July, 2017 at 0225hrs the aircraft arrived Sao Tome International Airport from Stavanger (Norway), via Luxemburg and Ghardaia (Algeria) as a Cargo flight. On 29th July, 2017 at about 0800hrs, the crew of CVK 7087 comprising the Captain, the First Officer, the Flight Engineer, the Flight Navigator and 2 Maintenance Engineers arrived the airport and commenced the flight preparation; pre-flight inspection, determination of weight and balance, computation of performance and take-off speeds. The crew received flight briefing/weather information and refuelled the aircraft with an uplift of 5,700kg. At 0850hrs, the crew requested engine start-up clearance from Sao Tome Tower and it was approved. After completing the engine start procedures, engine parameter indications on both engines were normal. Appropriate checklist was completed and taxi clearance was requested by the crew. Sao Tome Tower initially cleared CVK 7087 to taxi on runway (RWY) 11 as favoured by the prevailing wind. However, the crew requested RWY 29 for departure. This request was approved by the Tower and the aircraft re-cleared to taxi to RWY 29 for departure. Sao Tome Tower did not provide the flight crew with the information about possible presence of birds at the aerodrome, in particular, on the runway. At 0905hrs, the aircraft began the take-off roll. The First Officer was the Pilot Flying (PF) while the Captain was the Pilot Monitoring (PM). The engines and systems parameters were reported to be normal. According to the Captain, "In the first half of the take-off run from the runway, from five to six eagles got off the ground of the runway and flew dangerously close to the aircraft". He then requested the Flight Engineer to check if the flood lights were ON and to monitor the engine parameters. The crew asserted that they observed a rising and narrowing runway as the aircarft accelerated to a speed of 180 km/hr. They stated further: "At a speed of 180 km/hr, ahead, a flock of eagles, which were not seen before this moment began to get off the ground from the runway." The Captain took control of the aircraft and decided, after assessing the situation within 4 seconds that the best option for the crew was to discontinue the take-off. At that moment, the crew heard a bang, which they suggested could be a bird strike. This was followed by aural and visual indications on the annunciator panel such as “Left Engine Failure”, “Dangerous Vibration”, and “Take-off is prohibited” and the Captain immediately initiated a rejected take-off and instructed the Flight Engineer to deploy thrust reversers. The rejected takeoff was initiated about 5 seconds after sighting the birds, at a speed of 220km/h. According to the Captain, his decision was necessitated by the consideration of losing multiple engines due to bird strike if the take-off continued. The Captain said he pressed the brake pedals completely immediately after initiating the rejected take-off, subsequently he assessed the braking action as not effective and he used the emergency braking at a speed of about 130 km/h. On realizing that the aircraft would not stop within the remaining available runway length (about 272.3m) coupled with the presence of a ravine at the end, the captain intentionally veered to the right in order to extend the runway stopping distance and also avoid the ravine. The aircraft exited the runway at a speed of approximately 76 km/h. As the aircraft’s speed decayed to 60 km/h and just before the aircraft exited the runway, the Captain instructed the Flight Engineer to close the fuel emergency shutoff cock. The aircraft travelled a distance of about 95m from the exit point before plunging into the ravine. In the process, the forward fuselage separated from the bulkhead located immediately after the cockpit section. The aircraft came to rest at a location with coordinates: N002° 2' 51'' and E006° 42' 07''. The accident occurred in daylight at about 0905hrs.

After landing on runway 23 at Tamale Airport, the four engine aircraft failed to stop within the remaining distance. It went through a fence that was delimiting a work area as the runway was subject to an extension. Upon impact, the nose gear was torn off and the aircraft slid for few dozen metres before coming to rest. All 76 occupants escaped uninjured but the aircraft was damaged beyond repair. It was specified in a NOTAM that the runway 23 length was reduced to 1,860 meters and that works were in progress to extend runway 23, with the presence of men and equipment. So, caution was advised during landing and takeoff procedures.

Following an uneventful cargo flight from Lomé, the crew initiated the approach to Accra-Kotoka Airport. The visibility was reduced due to foggy conditions. After touchdown on runway 03, the aircraft became uncontrollable and veered off runway to the right. While contacting soft ground, it lost its undercarriage and its right engine before coming to rest in a grassy area. All three crew crew members escaped with minor injuries and the aircraft was destroyed.

On 2nd June, 2012 at 1828hrs Allied Air Ltd Flight DHV 111, a Boeing 727-221 Cargo aircraft, Registration: 5N-BJN, departed Murtala Muhammed International Airport, Ikeja, Lagos-Nigeria to Kotoka International Airport, estimating Accra, Ghana at 1904hrs, en-route to Abidjan. While taxiing for take-off, the Flight Engineer observed that the CSD amber light (caution) had illuminated on the panel. With the Captain’s permission, it was disconnected. The flight was cleared Flight Level 240 and to maintain by Accra Area Control on 130.9MHz. The Flight was operating under Instrument Flight Rules (IFR) conditions and the flight was turbulent, the aircraft was cruising at a speed of 280kts which is the recommended turbulence speed. On the descent into Accra, the aircraft was cleared by Accra Approach on 119.5MHz initially to Flight Level 50 and later cleared to 2000ft. It was again instructed to climb to 3000ft due to high ground. On arrival at Accra, the Captain flew an Instrument Landing System (ILS) coupled approach, until he saw the runway. He then disconnected the autopilot at 500ft and manually flew the aircraft. After disconnecting the auto-pilot, he came into heavy IMC conditions in rain. The aircraft experienced an unstable approach at a high speed of 167kts and landed with a wind of 050/15kts at 154 kts and about 5807 ft from Runway 21 in nil visibility. The crew deployed thrust reversers and applied the normal brakes as well as the emergency pneumatic brakes but these actions were ineffective to stop the aircraft. Normally deploying the thrust reversers or applying the brakes would bring the nose wheel down. However, the nose gear was kept up. The speed brakes were not deployed. The crew reported seeing red lights rushing towards them soon after the main wheels touched the ground for the landing run. The aircraft nose gear never touched the ground until the aircraft went over the fence wall. A Lufthansa Flight DLH 566 operated on behalf of Lufthansa (LH) by Private Air which had landed earlier at 1902hrs reported a wind of 050/15kts and visibility of 3800m in rain. From the 2nd intersection where DLH 566 had stopped, ready to backtrack Runway 21, the crew observed Allied Air appeared to have landed at very high speed when the aircraft went past and could not determine whether the aircraft was taking off. A Lufthansa ground engineer who was waiting at the intersection to receive DLH 566 indicated the approximate touchdown point of DHV 111. Both the controller at the Tower and the Marshaller in the “follow me” vehicle waiting at the 1st Intersection saw Allied Air land between the 1st and 2nd intersections. The FDR indicated that the aircraft landed 4000 ft to the end of Runway 21. The full length of Runway 21 is 3403 m (11,162ft for take-off) but available for landing is 2990 m (9,807 ft). The FDR readout showed that the aircraft landed at 150 kts, and at 1.6 G, 5807 ft from the beginning of Runway 21 and 4000ft from the threshold of the Runway 03. The runway surface condition for braking as described by DLH crew was good. Shortly after Turkish Airline (THY 629) had landed, DLH 566 also landed followed by DHV 111. The aircraft over-run the runway and destroyed the Threshold Lights and the Approach lights on Runway 03. It knocked out the ILS Localizer transmitter structure and mounts, broke through the airport perimeter wall. The aircraft crossed Giffard Road, collided with a passenger mini bus killing all ten (10) persons on board. It uprooted a tree by the road side before finally coming to a stop at an open space near El-Wak Sport Stadium. The Emergency Locator Transmitter (ELT) was triggered by the impact. The right side of a taxi cab on the road was grazed by flying debris from the localizer transmitter structures carried along by the right wing of the aircraft. The leading edge of the wing was extensively damaged. The aircraft came to a rest outside the airport perimeter wall 1171 ft (350m) from the Threshold of Runway 03, heading 215° southwest, coordinates 05 35 13.67N 000o 10 29.20W. The four (4) crew members sustained minor injuries. The aircraft and the mini bus were all destroyed. At 1910hrs, RFFS was alerted by the Tower Controller through the crash alarm bell. It took 9 minutes for the firemen to get to the crash site. The Airport was closed for 45minutes during which runway inspection was carried out. No pool of water was found anywhere on the runway. Approximately one hour after the aircraft had over-run the runway, the Airport was re-opened to traffic. Other airlines including KLM and British Airways, landed. Even though the Technical Log Book had no records of deferred defect, the Captain in an interview said the windshield wipers where switched on during the landing phase but were unable to clear the rain. It was observed during the investigation that the windshield wipers were rather ¾ switched on.

On the day of the accident, Flight DV110 routing was Abidjan – Accra - Lagos. It departed Abidjan at 1015 hrs for Lagos via Accra. The aircraft finally departed Accra for Lagos at 1145 hrs with a total declared cargo weight of 50014 lbs (22733 kgs). The aircraft contacted Lagos Area Control at 1242 hrs, while maintaining FL 210 (21, 000ft) and was given an in-bound clearance to Lagos VOR (LAG) for ILS approach on runway 18L. At 1252 hrs, Lagos Approach cleared it to FL050 (5,000 feet) and at 12 NM, it was further cleared down to 3500ft on QNH 1013 hpa, and finally to 2,200 feet and to report established on the ILS. At 4 NM to the runway, the aircraft reported fully established on the ILS and was handed over to Control Tower for landing instructions. At 1303 hrs and 2 NM to the runway, the aircraft was cleared to land on runway 18L but to exercise caution, as the runway surface was wet. The cloud was low; the Captain said in his statement that the cloud base was about 100 feet above minimum. Speci weather was also available to the crew. The pilot was advised to exercise caution due to the rain and the weather at that time. In spite of all the warnings the copilot was still allowed to proceed with the landing. At the point of touch down the captain observed that it was impossible to stop on the runway and he called for a go-around. The procedure was not properly executed and thus the aircraft overshot the runway 400m into the grass area. There was no fire outbreak and no injury was sustained by any of the crew members. There was serious damage to the aircraft.

The aircraft was completing a schedule service (flight GH200) from Tamale to Accra on behalf of the Ghana Air Force. On final approach to Accra-kotoka Airport, the crew encountered poor weather conditions with limited visibility due to heavy rain falls. In a nose down attitude, the aircraft landed hard on runway 21, nose first. Upon impact, the aircraft broke in two and came to rest. Seven passengers were killed while several others were injured, some seriously.

Crashed in unknown circumstances 13 km from Accra-Kotoka Airport. All five occupants were injured and the aircraft was damaged beyond repair.

Following an uneventful flight from Accra-Kotoka Airport, the crew started the descent to Abidjan-Félix Houphouët-Boigny Airport in poor weather conditions. Due to heavy rain falls, the horizontal visibility did not exceed 2 km and on final, the captain decided to initiate a go-around procedure. Few minutes later, the crew started a second approach to runway 21, established on the ILS but continued the approach above the glide. This caused the aircraft to land 900 metres past the runway threshold. On a wet runway surface, the aircraft skidded and veered off runway to the left. While contacting soft ground, the aircraft lost its undercarriage and came to rest 1,800 metres past the runway threshold. All 104 occupants were evacuated, among them three passengers were slightly injured. At the time of the accident, weather conditions were poor with heavy rain falls and wind from 110 gusting at 25 knots.

The approach to Monrovia-James Spriggs Payne Airport was completed in poor weather conditions with a visibility limited due to heavy rain falls. On final, the aircraft struck the ground short of runway threshold, causing the undercarriage to be torn off. The aircraft slid on its belly for about 500 metres before coming to rest on the runway. All 91 occupants evacuated safely and the aircraft was damaged beyond repair.

Crashed on landing for unknown reasons. There were no casualties.
