Scheduled Revenue Flight

On final approach to Nyagan Airport, the crew realized he was not properly aligned with the runway but decided to continue. Upon touchdown, the right wing struck the runway surface. The aircraft rolled left and right for about 800 metres then veered off runway and came to rest in a ravine. All 15 occupants were injured, six seriously.

After takeoff from runway 01 at Medellín-Enrique Olaya Herrera Airport, the aircraft encountered difficulties to gain sufficient height. About three minutes after liftoff, the aircraft struck the slope of Mt Padre Amaya located 8 km from the airport. The wreckage was found 30 metres below the summit. A passenger was found alive while 14 other occupants were killed.

Ethiopian Airlines flight ET961 had taken off from Addis Ababa, Ethiopia, at 08:09 hours UTC for a scheduled flight to Abidjan, Ivory Coast via Nairobi, Kenya; Brazzaville, Congo; and Lagos, Nigeria. Twenty minutes after takeoff, at about 08:29 UTC, one passenger stood up from his seat and ran up the aisle to the cockpit, and two other passengers followed him heading for the cockpit. While rushing to the cockpit one of the men said "Everybody should be seated, I have a bomb!". Then they opened the cockpit door and stormed in. They declared to the pilots that there were eleven hijackers on board and beat the First Officer and forced him out of the cockpit. They then grabbed the fire axe and fire extinguisher bottle from their respective stowages and ordered the pilot-in-command to change direction and fly to Australia. The pilot-in-command explained to the hijackers that he had not enough fuel to reach Australia and demanded to make a refueling stop at Mombasa. The hijackers refused the refueling stop and continued arguing with the pilot-in-command. They insisted that they had learned from the inflight magazine that the B767 could fly 11 hours without refueling. After passing Dar es Salaam one of the hijackers ordered him to fly away from the coast, head to Australia and indicating to the altimeter not to descend below FL390. The pilot-in-command turned left towards the Comoros Island. The lead hijacker was sitting in the first officer's seat and was fiddling with the aircraft's controls, kicking the rudder, whilst also drinking whisky. The pilot-in-command kept on telling them that he was running short of fuel pointing to the fuel quantity indicators, but the hijackers did not listen. The leader continued fiddling with the controls, trying to turn the aileron and pulling the reverse thrust lever at random. As the flight came over the Comoros Islands the pilot-in-command saw the Moroni International Airport runway and circled 15-20 nm south of the field. Then the LOW FUEL CAUTION came on. The pilot-in-command pleaded to land because of low fuel. The hijackers were unconcerned and only insisted that the pilot not descend below FL390. At about 11:41 UTC the right engine ran down to wind milling speed. The pilot-in-command showed the red warning message for the right engine on the EICAS to the hijacker. At this moment, the hijacker left the right seat and went to the cabin door to discuss with the other two hijackers. This gave the captain the opportunity to pick up his microphone and address the passengers: "....ladies and gentlemen this is your pilot, we have run out of fuel and we are losing one engine this time, and we are expecting crash landing and that is all I have to say. we have lost already one engine, and I ask all passengers to react ..... to the hijackers ....". The hijacker then came back to the cockpit and hit the microphone out of the pilot's hand. After the right engine failed, the pilot started to descend the aircraft in order to increase speed, but the hijacker again interfered and violently played with the controls which resulted in improper control inputs. As a result the autopilot was disconnected and the flight became erratic with the airspeed varying between 216 and 336 kts. As the pilot regained control of the aircraft, the left engine went dead. The hijacker kept on instructing the pilot not to descend and again went to the cabin. Upon returning to the cockpit he saw that the altitude was decreasing, and angrily shouted at the pilot not to go any lower. The pilot said that the fuel was already finished and that the engines were without power. This time the hijacker instructed the captain not to touch the controls, and threatened to kill him. The captain said, "I am already dead because I am flying an airplane without engine power." The first officer, who had earlier been forced out to the First Class cabin, got up and, via the right aisle, went to the rear of the aircraft where he saw that a lot of economy class passengers had their life jackets on and that some had already inflated them. The first officer, along with the cabin crew members, helped the passengers to deflate the life jackets and showed them how the jackets should be re-inflated and how to assume the brace position during impact. While returning to the front of the aircraft, they repeated the same instructions as many times as they could. About less than 2 minutes before the ditching, the co-pilot forced his way to the cockpit shouting "let me help the pilot ...". After adjusting his seat and seat belts the pilot asked him for help since the controls were heavy. The hijackers still kept on struggling with the controls. By now, the aircraft was descending into the Indian Ocean over the Comoros Islands. The aircraft now had only standby instruments and RAT (Ram Air Turbine). The altimeter was indicating 150 feet and the airspeed was 200 kts. By this time the flight crew had been left alone to assume control. They turned the aircraft to the left in order to parallel the waves. However, the aircraft brushed the water in a left-wing-low attitude. It was then held straight and level after which it broke into four sections and came to rest in the sheltered waters 500 metres off Le Galawa Beach. Of the 175 occupants, 6 crew members and 119 passengers were fatally injured in the accident. Six crew members and 38 passengers sustained serious injuries, 2 passengers sustained minor injuries and 4 passengers received no injury.

The aircraft was damaged beyond repair when it veered off runway and the crew tried to get back on the runway without help. The aircraft went out of control, crossed the runway and hit the mast of a powerline and a parapet with more than 3.5 g, suffering structural damage. All 5 crew members and 22 passengers (19 of them illegal ones) escaped unhurt.

The Beechcraft 1900C, N87GL, was in its landing roll on runway 13, and the Beechcraft A90, N1127D, was in its takeoff roll on runway 04. The collision occurred at the intersection of the two runways. The flight crew of the Beechcraft 1900C had made appropriate efforts to coordinate the approach and landing through radio communications and visual monitoring; however they mistook a Cherokee pilot's transmission (that he was holding for departure on runway 04) as a response from the Beechcraft A90 to their request for the Beechcraft A90's intentions, and therefore mistakenly believed that the Beechcraft A90 was not planning to take off until after the Beechcraft 1900C had cleared the runway. The failure of the Beechcraft A90 pilot to announce over the common traffic advisory frequency his intention to take off created a potential for collision between the two airplanes.

While taxiing at Đà Nẵng Airport, the nose gear collapsed and apparently punctured the cockpit, injuring a crew member. The aircraft was considered as damaged beyond repair.

While parked at Most Pyssa for a short period of time (a 20 minutes stop), on a flight from Vazgort to Koslan, weather conditions deteriorated with snow falls. The crew failed to remove the snow from the aircraft prior to departure. After takeoff, while climbing, the crew initiated a turn to the left when the aircraft stalled and crashed in a wooded area, bursting into flames. The copilot survived while 14 other occupants were killed.

The Ilyushin II-76TD departed Shymkent Airport on a regular schedule service (flight KZA1907) to New Delhi-Indira Gandhi, carrying 27 passengers and 10 crew members. Following an uneventful flight, the crew was cleared to start the descent to New Delhi via route G452 and was instructed to maintain FL150. At 1833LT, a Boeing 747-168B operated by Saudi Arabian Airlines (Saudia) departed New Delhi-Indira Gandhi Airport on a flight to Jeddah (flight SV763) with an intermediate stop in Dhahran, carrying 289 passengers and 23 crew members. After takeoff, its crew was instructed to climb to FL140 via the same route G452. For unknown reasons, the Kazair crew continued the descent below FL150 until both aircraft faced each other and collided at 1840LT at FL140, seven minutes after the B747 takeoff. After the collision, both aircraft entered an uncontrolled descent and crashed in an open field located about 3 km Charkhi Dadri, some 80 km west of New Delhi-Indira Gandhi Airport. Both aircraft were destroyed by impact forces and a post crash fire and all 349 occupants in both aircraft were killed.

The aircraft departed New Delhi-Indira Gandhi Airport at 1833LT on a flight to Jeddah with an intermediate stop in Dhahran, carrying 289 passengers and 23 crew members. After takeoff, the crew was instructed to climb to FL140 via route G452. Seven minutes after takeoff, while cruising at an altitude of 14,000 feet, the aircraft collided with a Kazakhstan Airlines (Kazair) Ilyushin II-76TD that was descending to New Delhi Airport. Registered UN-76435, it was completing flight KZA1907 from Shymkent with 27 passengers and 10 crew members on board. After the collision, both aircraft entered an uncontrolled descent and crashed in an open field located about 3 km Charkhi Dadri, some 80 km west of New Delhi-Indira Gandhi Airport. Both aircraft were destroyed by impact forces and a post crash fire and all 349 occupants in both aircraft were killed.

After takeoff from Port Harcourt Airport, the crew was cleared to climb to FL240. At 15:47 the flight established initial contact with Lagos Approach Control, and was assigned a transponder code. At 15:54 the flight reported crossing SEPER point. After this position report, the flight appeared not to be maintaining a listening watch, as it gave no reply to two consecutive calls from Approach Control, and then after some time replied to a transmission not meant for it. At the same time a Triax Airlines Boeing 727 (Flight TIX185) had departed Lagos and was flying at FL160 towards Enugu. The Lagos controller had terminated contact with the Triax aircraft when the ADC crew requested to descend. The permission to descend was delayed to allow a corporate jet (5N-APN) to pass beneath the 727 at FL210. At 15:59 Lagos Approach Control then cleared the flight to FL160 and subsequently requested the flight to contact Lagos Radar. The flight was identified by Lagos Radar 41 miles south-east of the airport, and instructed it to fly the heading of 320° to avoid Triax flight 185, and to descend to FL50. At 16:02.50 Lagos Radar instructed the aircraft two times in succession to maintain heading 300. The captain then took over control from the copilot by stating: "I have it." At 16:03.08 the flight reported: "I have the traffic... and I continue my heading to 330 to avoid him". This was the last transmission. The records of the FDR show that flight 086 was maintaining a steady coordinated turn towards heading 330 for the first 10 seconds of the last 50 seconds of the flight. After 15 seconds, the airplane was put in bank angle of 43.2°. It maintained this configuration for 10 seconds before the bank angle increased to 68.8 degrees. This attitude was observed for 5.5 seconds before it was further increased to 83 degrees. The airplane must have suffered from high speed stall and gone into a roll with a nose down attitude. The aircraft appeared to be recovering just before it impacted the lagoon water because it succeeded in reducing the vertical acceleration from 8.44 to 2.1 G and the bank angle to 61.6°. But it did not have sufficient height to make a full recovery and crashed in the lagoon about 7,5 km west of Ejirin. The wreckage was found in the afternoon of the following day. The aircraft disintegrated on impact and all 144 occupants were killed.
