Shortly thereafter, the aircraft received clearance from the controllers to climb to 23,000 feet (6,900 meters). The plane continued its straight flight for a while. TK981 was scheduled to fly from Istanbul to London Heathrow, with a stop in Paris Orly airport. McCormick managed to solve this problem by making his turns primarily with the engines, using differential thrust to adjust their heading, while holding the ailerons just far enough left to keep the wings level. Mr. Carlo Alberto Fontana, 38, married, one child, engineer An Airworthiness Directive was immediately issued by the Federal Aviation Administration (FFA),[3] calling for strengthening the load floor and control cables. Known as the "Ermenonville air disaster", from the forest where the aircraft crashed, the accident resulted in the deaths of all 346 on board. DC-10-10, a miracle in jet aviation, was the second widebody jet developed . This makes it particularly important that the locking mechanisms be secure. J. When Turkish Airlines Flight 981 arrived in Paris from Istanbul, many passengers scheduled to fly on British European Airways transferred to 981 for its final leg to London. The DC-10 plowed through the trees for the better part of a kilometer, disintegrating utterly as it went, carving out a hellish trail of shattered pine trees, riven soil, and pulverized metal. And Turkish Airlines seemed like the easiest place to begin. choose Qatar Airways, which departs at 09:25 The last flight for this route is Vueling, Turkish Airlines, departing at 22:40 Zagreb Airport . . It would have been tempting to immediately try to return to the airport, but with the plane no longer in danger of spiraling into the ground, McCormick decided to first take stock of the situation. Mr. Mark Dunsford Dottridge, 31, writer Baggage handler Mohammed Mahmoudi was assigned to deal with the rear cargo door, but after waiting for some time, he was told that no bags would be placed there and that he should close the door. Mr. Masaki Imazeki, 23, bank management trainee However, while the FAA agreed that the locking and electrical systems should be upgraded, it also agreed with McDonnell-Douglas that the additional venting would be too expensive to implement, and did not demand that this change be made. Delegation is necessary to some extent because the FAA lacks enough staff to certify every part of every new airplane. This was especially problematic given that the mechanism was extremely weak, and the torque tube would bend under as little as 80 pounds (355 Newtons) of force, well within the capability of the average human. To solve these recurring problems, in 1972 McDonnell Douglas devised a more robust wire which would mitigate the voltage drops, and issued a service bulletin encouraging DC-10 operators to install it. As the plane climbed, the pressure acting on the door was transmitted through the hinges and into the latch actuator bolts, until the bolts sheared off under the strain at 11,750 feet, causing the cargo door to depart the airplane. Facing these twin pressures, Turkish Airlines agreed to buy the planes on three conditions: that the cargo doors be made safe; that McDonnell Douglas provide extensive technical support; and that the planes be ready to fly in time for the Christmas travel rush. After Flight 96, McDonnell-Douglas added a small peephole that allowed the baggage handlers to visually inspect the pins, confirming they were in the correct position, and placards to show the correct and incorrect positions of the pins. McDonnell Douglass response to this serious failure in testing was to make a few minor changes to the design of the door. But, with the gift of hindsight, it is possible to say that being the first was both a blessing and a curse. A McDonnell Douglas DC-10, flying as American Airlines Flight 96, had experienced an explosive decompression in the aft cargo hold in June 1972. No one, not even the experienced police captain, could have been prepared for what they actually found. There was nothing actually wrong with Applegates argument, he wrote in his official reply the possibility of failure was real, as was the likelihood that Convair would be held liable in the event of a crash. Mr. Francis Michael Hope, 35, married, one child, journalist But McDonnell Douglas never wavered from its belief that human error was the only cause of cargo door failures, as the company blamed the Windsor incident on ground agent William Eggert, and even attempted initially to pin the Turkish airlines disaster on the illiterate baggage handler Mohammed Mahmoudi, who hadnt even deviated from proper procedure (Mahmoudi also pointed out that he was in fact literate in three languages, thank you very much!). Mr. Robert Briggs Savidge, 20, assistant farm manager During the rush to get people onto flights, record-keeping at the Turkish Airlines gate had been spotty, and rescuers were initially given a figure of 185, which would in itself have made this the deadliest plane crash ever at the time. The design that they came up with worked something like this. You can reach the final report of that accident via the official report link. Mr. Christopher Mather Kendall, 31, married, two children, company director It should be noted, however, that a view port was provided so that there could be a visual check of the engagement of the lock pins. Turkish Airlines flight 981 was a scheduled flight of the Turkish airline Turkish Airlines from Istanbul to London Heathrow with a stopover at Paris-Orly Airport.The wide-body aircraft of the type McDonnell Douglas DC-10 with the aircraft registration TC-JAV and the name Ankara took off on Sunday, March 3, 1974 around noon from Paris-Orly. Mr. Thomas William Addis, 71, widower, four children, retired driver Flight 981's captain was Nejat Berkz, age 44, with 7,000 flying hours. The first aircraft accident in which 200 or more people died occurred on March 3, 1974, when 346 died in the crash of Turkish Airlines Flight 981.As of April 2020, there have been 33 aviation incidents in which 200 or more people died.. [2] The plane, owned by Mitsui, was originally to be purchased by All Nippon Airways, but the Japanese airline declined the aircraft in favor of the Lockheed L-1011 TriStar. The door, along with the coffin and the other contents of the rear cargo hold, had fallen to earth near the city of Windsor, Ontario, and was found in relatively good condition. But when the job got out of machine control and depended on human attention, major accidents also became inevitable. Also, a support plate for the handle linkage had not been installed, although manufacturer documents showed this work as completed. By the following year, most of the obvious kinks had been ironed out, and the DC-10 entered passenger service with American Airlines in August 1971. The 747 had a small plug-type vent door within the cargo door, which was driven closed by the lock tube itself; if the lock tube did not fully extend, the vent door would not close, indicating that the door was not locked. Mr. Tsukuru Yoshitake, 22, trading company management trainee, Mr. Penn Boyd Blair, 29, married, one child, machine company vice-president Mr. Gary Ray Chard, 36, married, four children, airline sales manager Miss Prudence Hedley Pratt, 30, fashion model Finally, the latching had been performed by a baggage handler who did not speak Turkish or English, the only languages provided on a warning notice about the cargo door's design flaws and the methods of compensating for them. At Orly airport, 50 passengers are scheduled to disembark. We hope that our visitors will appreciate and we help them to increase their aviation culture. Mr. Richard Tomlin Coult, 22, civil engineer Dirt and dust blasted upward into McCormicks face, temporarily blinding him. To lock the door, a ground handler pushes down on a handle on the outside of the door. But as he held down the button to drive the latch actuator, the voltage dropped and the actuator stopped before the hinges could move over-center. On 3 March, 1974, the McDonnell Douglas DC-10[1] operating the flight suffered an explosive decompression and crashed into the Ermenonville Forest, shortly after it had left Paris. Mr. Arthur Lawrence Cornish, 39, married, one child, printer Turkish Airlines Flight 981Infrastructural Failure of a DC-10. In fact, most of the DC-10 fuselage had vents like these; only the rearmost hold lacked them. But the worst did not come. In order to raise capital, both manufacturers courted orders from Americas largest airlines, and the battle lines were drawn: TWA and Eastern chose the L-1011, while American and United opted for the DC-10. This relatively small airline had only recently made the upgrade to jet aircraft and was by no means ready to buy something as large and complex as the DC-10. Mr. Peter Frederick Warnett, 36, married, one child, technical services representative Mr. Yasunori Takashima, 23, bank management trainee Flight 981 took on over 100 amateur English rugby players, a group of Spanish models, and several dozen Japanese trainee bank managers. Mr. Takeo Shinmi, 22, bank management trainee Five minutes after the crash, local police Captain Jacques Lannier was having lunch with his family at the Officers Club in the nearby village of Senlis when he received a phone call from his personal assistant: apparently a plane had gone down in the Ermenonville Forest. This was the worst air accident until 1977, when two 747's collided on a runway, killing 583 people. It moved into place normally, the vent door closed, and the warning light went out in the cockpit. The deal was closed in late September 1972, leaving very little time to get the planes and the airline ready by Christmas. Quite simply, the extra weight of passengers caused the cabin floor to fail more completely than in the Windsor incident, when no passengers were seated in the area above the rear cargo hold. A holding company in Japan had purchased six DC-10s with the expectation that they could up-sell them to All Nippon Airways; but due to some kind of backroom deal, that airline decided to buy the Lockheed L-1011 instead. His serious reservations about the integrity of the DC-10's cargo latching mechanism are a classic case in engineering ethics. (981 kilometers). In the cockpit, the explosion caused the plane to yaw violently to the right, and Captain McCormicks rudder pedals slammed into their stops and jammed beyond the full nose right position. Plane Spotting. On 3 March, 1974, the McDonnell Douglas DC-10 [1] operating the flight suffered an explosive decompression and crashed into the Ermenonville Forest, shortly after it had left Paris. The first leg of the Istanbul-Paris-London flight of Turkish Airlines with flight number 981 was completed without any problems. So was it THY that mis-rigged the cargo door after the Americans went home? Despite these failures, the pilots were able to save their plane using the ailerons, wing engines, and the right elevator. Any force transmitted through the latches themselves will attempt to push the hinge even farther over-center, which is rendered impossible by a metal stop that limits the movement of the hinge. On 3 March 1974, the McDonnell Douglas DC-10 operating the flight crashed into the Ermenonville Forest, outside Paris, killing all 346 people on board. 216 new passengers, many of whom were supposed to fly on Air France, BEA, Pan Am or TWA, boarded TK 981 in Paris. Certainly her crew, consisting of Captain Bryce McCormick, First Officer Peter Whitney, and Flight Engineer Clayton Burke, could not have expected that their brand new plane, flying in perfect weather, was about to throw them into a terrifying fight for survival. [2] The aircraft's original pitch angle was negative 20 degrees, resulting in the aircraft accumulating a massive amount of airspeed during its quick descent. The concept of over-centering is found most commonly in a household light switch: once the switch is pushed past the center point, it will slip into the opposite detent, and only a new force equal to the original force will push it back. Mr. Yasuhiro Tominaga, 44, married, two children, company manager It was proven by tests that the door subsequently yielded to about 15psi (100kPa) of pressure, in contrast to the 300psi (2,100kPa) that it had been designed to withstand.[11]. An improper adjustment had been made to the locking pin and warning light mechanism, however, causing the locking pin travel to be reduced. Mr. Stuart Frank King, 19, salesman (Although most Turks are Muslim, the government heavily subsidized travel costs for Turkish migrant workers in Europe who used the Christmas holiday to come home to Turkey, and THY was eager to cash in.). The overspeed warning began to blare as the plane accelerated through 362 knots. The pilots tried to save their crippled plane, but the pitch controls had been destroyed, sending the plane into an irrecoverable dive, and the jet crashed less than two minutes later in the Ermenonville Forest, killing all 346 passengers and crew.

Mr. John Anthony Law-Wright, 33, married, two children, engineer and his wife Susan Vanessa, 28 Mr. Martin Robert Perry, 26, married, insurance agent TK981 was scheduled to fly from Istanbul to London Heathrow, with a stop in Paris Orly airport.
