Circumstances:
Following an uneventful flight from Paris-Orly, the crew was cleared to descend to FL070 at 2049LT then to FL060 at 2055LT. Then the crew was instructed to turn right to 178° to the VOR of Vienne but after passing VNE VOR, he followed a wrong track off 155°. At 2058LT, the crew was transferred from Lyon-Satolas Approach to Valence Approach with whom the radio contact was established 30 seconds later. The crew was cleared to descend to 3,500 feet for a specified arrival route Vienne - Valence. A right turn to 200° was initiated when, at a speed of 187 knots, the aircraft struck the vertical cliff of 'Pierre Chauve' (1,260 meters high) located near Léoncel. The aircraft disintegrated on impact and all 22 occupants were killed.
Probable cause:
The accident is the direct result of a navigational error. This error had the direct causes:
- The display and use the VOR LSA (Lyon-Satolas) instead of VNE (Vienne),
- An insufficiency in the mental representation of the path of the aircraft despite other available information.
Moreover, the lack of rigor in the division of work in their execution and in the mutual control are contributing factors.
The Committee also noted that the following facts have facilitated the development of a critical situation:
- Documentation of the crew used for navigation and organization of the dashboard of the plane could be sources of error,
- The organization of the airspace in the region of Valence did not allow optimal use of existing radar,
- The tasks of the crew were not defined by the operator,
- The copilot had a moderate but significant blood alcohol level.

Circumstances:
Following a night takeoff at Montluçon-Guéret Airport, while in initial climb, the aircraft nosed down and struck the ground 600 meters past the runway end. It slid for few dozen meters, collided with bushes and eventually came to rest, bursting into flames. All four occupants were killed. It appears that the Stall Avoidance System (SAS) had activated, resulting in the stick pusher activation at a critical altitude. The Metro's SAS system, as well as the SAS system on this particular aircraft, had a history of problems. These problems resulted in several NTSB Safety Recommendations (A-84-66, A-88-154). The copilot was at controls at the time of the accident.
Crew:
Gérard Van Der Veecken, pilot,
Christian Rémondon, copilot.
Passengers:
Robert Aupetit,
Patrick Desdoit.
Probable cause:
The accident resulted from a reduction in the attitude of the airplane causing a downward trajectory in the moments that followed the takeoff. It is likely that this decrease in attitude is due to an untimely triggering of the stick pusher. The absence of a recorder and the complete destruction of the SAS (apart from angle of attack vane and its transmitter) did not prove this hypothesis. With or without inadvertent triggering of the stick pusher, the imprecision of the right horizon and the absence of external visual references played an important role in this accident.

Circumstances:
Following an uneventful flight from Nancy-Essey Airport, the crew started the descent to Paris-Orly Airport and was cleared to reduce his altitude to 6,000 feet. At that time, weather conditions were marginal with poor visibility due to fog. Suddenly, the aircraft pitched down and entered an uncontrolled descent with a rate of 16,000 feet per minute during the last 20 seconds. Out of control, the aircraft struck the metallic pylon of a high voltage powerline and eventually crashed at an excessive speed of 630 km/h in an open field located in Machault, about 46 km southeast of Paris-Orly Airport. The aircraft disintegrated on impact and all 24 occupants were killed.
Probable cause:
It was determined that the electrical system failed in flight while the crew was flying under IFR mode in IMC conditions. Technical analysis and investigations were unable to determine with certainty the exact cause of the loss of control and the fatal descent. After eliminating various assumptions invalidated by the established facts and findings and after reviewing the results of flight tests conducted at its request, the commission assigned higher probability to the hypothesis that the electrical fault caused a loss of attitude reference and autopilot disconnect which would have occurred while the aircraft was configured 'out of trim' in a nose down attitude. In the absence of independent standby horizon, the crew had no usable attitude reference immediately available while the aircraft was in a high-speed dive.
The following findings were reported:
- The loss of control occurred in icing conditions,
- A third person (non crew) aged 18 was seating in the cockpit at the time of the accident,
- The aircraft's speed upon impact was 100 km/h above the max allowable speed certification.

Circumstances:
During the takeoff roll on runway 36L at Toulouse-Blagnac Airport, at a speed of 110 knots, the captain started the rotation while the engine n°4 was not running properly. After liftoff, the aircraft banked right, causing the right wing tip to struck the runway surface. Out of control, the aircraft stalled and crashed 136 meters to the right of the runway. It broke in two and burst into flames. All four occupants were injured.
Probable cause:
It was determined that the accident was the consequence of a loss of control at rotation during a takeoff carried out according to an unsuitable procedure. The loss of control was caused by the huge drag created by the engine n°4 propeller that was running in idle position, leading to a minimum air control speed greater than the takeoff speed. The progressive deterioration of the weather conditions preoccupied the crew and focused his attention, at the expense of the problem on engine n°4. The decision to take off on three engines was announced during taxi only and the improvised takeoff procedure was not analysed by the crew prior to departure.

Circumstances:
Following an uneventful cargo flight from Paris-Orly Airport, the crew started the descent to Douala Airport in marginal weather conditions. On short final, the airplane encountered low level windshear. Control was lost and the aircraft banked left, causing the left wing to struck the runway surface. Upon impact, the left main gear was torn off as well as both engines n°1 and 2. The aircraft veered off runway to the left, made a 270° turn then came to rest. All three crew members escaped with minor injuries while the aircraft was damaged beyond repair, the left wing being partially torn off.
Probable cause:
Loss of control on short final due to windshear.

Circumstances:
Flight KE902 departed Paris-Orly Airport at 1339LT on a flight to Seoul with an intermediate stop in Anchorage. After passing the North Magnetic Pole, while approaching Ellesmere Island, Canada, the airplane initiated a turn to the right by 150° instead continuing straight-in to North Canada and Alaska. This caused the airplane to fly to the southeast, over the Barents Sea and then into Soviet airspace, reaching the Soviet coast approximately three hours and 2,400 km after its right turn. The aircraft was intercepted by a Soviet Air Force Sukhoi SU-15TM and was forced to land. For reasons undetermined, the Korean crew did not respond to multiple requests and initiated a turn when the Soviet pilot was instructed to shoot down the Boeing 707. One of the air/air missile struck the left wing and four meters were torn off. The missile also punctured the fuselage, causing rapid decompression and jamming one of the plane's four turbines. From an altitude of 30,000 feet, the crew initiated a rapid descent and eventually completed an emergency landing on the frozen Korpijärvi Lake located in the region of Kem, Republic of Karelia. Two passengers were killed during the attack while all other occupants were evacuated, 13 were injured. Both pilots and the navigator were arrested but released on April 29.
Probable cause:
It is believed that the airplane deviated from the prescribed flight plan directly after it passed over the North Magnetic Pole, causing major disturbance of the aircraft's magnetic compass-based navigation systems. For the Soviet Authorities, the deviation was the consequence of a navigation error on part of the flying crew.

Circumstances:
On Sunday March 3, 1974 flight TK981 departed Istanbul for a flight to Paris and London. The DC-10 landed at Paris-Orly at 11:02 and taxied to stand A2. There were 167 passengers on board, of whom 50 disembarked. The aircraft was refueled and baggage was loaded onto the plane. The planned turnaround time of one hour was delayed by 30 minutes. An additional 216 passengers embarked. Most of the passengers were booked on this flight because of a strike at British Airways. The door of the aft cargo compartment on the left-hand side was closed at about 11:35. When all preparations were complete the flight received permission to taxi to runway 08 at 12:24. Four minutes later the crew were cleared to line up for departure and were cleared for departure route 181 and an initial climb to flight level 40. The aircraft took off at approximately 12:30 and was cleared by Orly Departure to climb to FL60, which was reached at 12:34. The North Area Control Centre then cleared TK981 further to FL230. Three or four seconds before 12:40:00 hours, the noise of decompression was heard and the co-pilot said: "the fuselage has burst" and the pressurization aural warning sounded. This was caused by the opening and separation of the aft left-hand cargo door. The pressure difference in the cargo bay and passenger cabin, the floor above the cargo door partly collapsed. Two occupied tripe seat units were ejected from the aircraft. All the horizontal stabilizer and elevator control cables routed beneath the floor of the DC-10 and were thus also severely disrupted. Also the no. 2 engine power was lost almost completely. The aircraft turned 9 deg to the left and pitched nose down. The nose-down attitude increased rapidly to -20 deg. Although the no. 1 and 3 engines were throttled back the speed increased to 360 kts. The pitch attitude then progressively increased to -4 degrees and the speed became steady at 430 kts (800 km/h). At a left bank of 17 degrees the DC-10 crashed into the forest of Ermenonville, 37 km NE of Paris. The aircraft disintegrated on impact and all 346 occupants were killed, among them 48 Japanese citizens and almost 250 British people.
Probable cause:
The accident was the result of the ejection in flight of the aft cargo door on the left-hand side: the sudden depressurization which followed led to the disruption of the floor structure, causing six passengers and parts of the aircraft to be ejected, rendering No.2 engine inoperative and impairing the flight controls (tail surfaces) so that it was impossible for the crew to regain control of the aircraft. The underlying factor in the sequence of events leading to the accident was the incorrect engagement of the door latching mechanism before take-off. The characteristics of the design of the mechanism made it possible for the vent door to be apparently closed and the cargo door apparently locked when in fact the latches were not fully closed and the lock pins were not in place. 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. This defective closing of the door resulted from a combination of various factors:
- Incomplete application of Service Bulletin 52-37;
- Incorrect modifications and adjustments which led, in particular, to insufficient protrusion of the lock pins and to the switching off of the flight deck visual warning light before the door was locked;
- The circumstances of the closure of the door during the stop at Orly, and, in particular, the absence of any visual inspection, through the viewport to verify that the lock pins were effectively engaged, although at the time of the accident inspection was rendered difficult by the inadequate diameter of the view port.
Finally, although there was apparent redundancy of the flight control systems, the fact that the pressure relief vents between the cargo compartment and the passenger cabin were inadequate and that all the flight control cables were routed beneath the floor placed the aircraft in grave danger in the case of any sudden depressurization causing substantial damage to that part of the structure. All these risks had already become evident, nineteen months earlier, at the time of the Windsor accident, but no efficacious corrective action had followed.
