Circumstances:
The aircraft was on a ferry flight from Minsk, Belarus, to Bamako, Mali, with intermediate stops in Zagreb, Marseille, Oran and Tamanrasset. It was returning to its country following maintenance in Minsk factory. While cruising by night in poor weather conditions, the crew failed to realize that the airplane deviated from the prescribed flight path. Due to opposite traffic, the crew was instructed to make a 360° right turn but apparently did not understand this message. At an altitude of 10,000 feet, the airplane struck the slope of Mt L'Avalanche located about 1,500 meters west of Estenc, Alpes-Maritimes. The wreckage was found few hours later. The airplane was totally destroyed upon impact and all seven occupants, five crew members and two passengers (two mechanics) were killed. At the time of the accident, the airplane equipment was compliant but due to stormy weather and strong winds, a precise navigation was impossible due to the lack of a VOR receptor. On the route Genoa - Albenga - Nice, the airplane failed to follow the G7 Airway due to stormy weather and in accordance with ATC. The Russian pilot-in-command, speaking neither English nor French, could not converse directly with ground control. The co-pilot, speaking French but not Russian, could not converse directly with the captain or translate his orders from the ground. The navigator, in charge of the route in particular difficult conditions, could not correspond more with the pilot, if not by means of the radio. Only the radio could translate into Russian to the captain the indications provided in French by the ground control, which could ipso facto introduce a source of error of interpretation, and required a certain time of translation. The ICAO recommendation suggesting to the pilot-in-command the use of English or the language used by the ground station was not applied. The investigation established that the crew was unaware of wind and drift. Under the influence of a wind blowing from sector 210 to 100 km/h, the aircraft suffered a drift of about 20° towards the north, thus towards the mountain. Vertical to Nice, the airplane was already 25 kilometers north of the station and north of the G7 Airway. The diversion order did not have to be understood the first time since the crew requested repetition. The superposition of the orders of two simultaneous maneuvers, turn and descent, probably made the interpretation tricky and ambiguous. The order to make a 360° right turn, which means a circular turn, was erroneously understood as the order to take heading 360. Indeed, at least five kilometers prior to impact, the aircraft was following a straight path, in this case a heading oriented almost to magnetic north. Under the influence of one or more stormy areas northwest of Nice, the unstable indications of the radiocompas did not allow position's control and turbulences could create an additional difficulty. The aircraft approached the terrain as fast as it did to the north and the speed of the aircraft at that heading increased by about 100 km/h, representing the wind speed south-southeast. The point of impact was 2,440 meters, the level 80 towards which the aircraft was normally descending corresponding to an altitude of 2'380 meters.
Probable cause:
The commission of inquiry considers that the accident of the TZ-ABH is due to the accumulation of two main errors acting in the same direction. A navigational error due to the violence of an unknown or underestimated southern sector wind that caused a large uncorrected drift and caused the aircraft to crash. An error in the interpretation of a control order, due to a complexity of conversation exchanges. This error determined the pilot to take, from a position well north of the Airway, the 360​​° heading, which caused the aircraft to move further towards the terrain. This misinterpretation can itself be attributed to the fact that there is no international phraseology for the orders given by the control to the airplanes. These errors were aggravated by very bad weather conditions. These meteorological conditions: storms and very strong turbulences, could constitute aggravating causes by making difficult the work of the crew and in particular the navigation using the radiocompas medium frequency, the only radionavigation instruments the aircraft was equipped with. The fact that the aircraft was following an east-west route contrary to the flight plan forecast and that its altitude was too low given the route followed are still contributing factors.

Circumstances:
The pilot was conducting a ferry flight out from Memphis-Metropolitan Airport. While in cruising altitude, the airplane entered an uncontrolled descent. Due to overload failure, several parts of the airplane separated and it eventually crashed in an open field located near South Haven. The pilot, sole on board, was killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it is believed the loss of control was the result of a temporary pilot incapacitation.

Circumstances:
The crew obtained a special ferry permit and departed Goodyear-Litchfield Airport (five miles away) bound for Litchfield Park. On approach, smoke spread in the cockpit and after a normal touchdown, the crew vacated the runway via a taxiway and stopped the aircraft. While the crew evacuated safely, the airplane was totally destroyed by fire.
Probable cause:
Powerplant-fuel fed engine fire for undetermined reason. Fire pattern indicated started in accessory section.

Circumstances:
A Lear Jet Model 23, N804LJ, operated by the Lear Jet Corporation crashed eight miles east-northeast of Jackson, Michigan, at approximately 1935 e.s.t., on October 21, 1965. The pilot and copilot were killed. There were no passengers. The aircraft was destroyed by impact. The flight was operating in accordance with an Instrument Flight Rules flight plan from Detroit, Michigan to Wichita, Kansas, at an assigned altitude of Flight Level 250. The radar controller working the radar contact at 1933, and observed the target traveling in a southwest direction ". . . when the aircraft started a sharp turn to the right (i.e. north) (sic). As the aircraft passed through a northerly heading the beacon target disappeared from the radar." The aircraft was traversing an area of moderate to severe turbulence when it deviated from the assigned route.
Probable cause:
The Board determines that the probable cause of this accident was a loss of adequate attitude reference resulting from AC electrical power failure under night, turbulent conditions.

Circumstances:
The crew obtained a special ferry permit to fly to Ardmore Airport with one engine inoperative. After touchdown on a wet runway, the airplane encountered difficulties to stop within the remaining distance, overran and came to rest into a ditch. All three crew members were evacuated safely while the aircraft was damaged beyond repair. At the time of the accident, it was dark with a limited visibility due to fog. It was reported that between 1855LT and 0040LT, 0,61 inch of rain fell at Ardmore Airport.
Probable cause:
The airplane suffered hydroplaning on a wet runway and was unable to stop within the remaining distance. The following factors were considered as contributing:
- poorly planned approach,
- misused or failed to use flaps,
- thrust unable to reverse,
- low ceiling,
- rain falls,
- restricted vision due to a dirty windshield.
