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.
