Circumstances:
Mohawk Airlines flight 411, while en route to Glenn Falls from Albany, New York, crashed about 2020LT in mountainous terrain approximately 9 nautical miles north of the Warren County Airport, Glenn Falls. The flight had been cleared for a VOR approach to runway 19, since the surface wind was from 150° at 12 knots with gusts to 20 knots. The ceiling at Glenn Falls was given as 2,100 feet overcast, and the visibility was 7 miles in light rain. The flight overflew Glenn Falls at 3,000 feet and proceeded north for about 1 minute and 15 seconds at which time a left turn was initiated preparatory to return to the airport to land on runway 19. During the last portion of this turn, the aircraft contacted trees and the northwest slope of the Pilot Knob Mountain on a heading of about 180°, approximately one nautical mile east of Katsskill Bay, New York. It then impacted the face of a rock cliff, after which it dropped approximately 38 feet, became lodged between trees and the side of the mountain, and burned. The elevation of the initial impact with the rock face of Pilot Knob Mountain was approximately 1,960 feet. The three crew members and 11 passengers received fatal injuries, and the aircraft was destroyed.
Probable cause:
The probable cause of this accident was that the captain, while conducting an approach, exceeded his clearance limits and, thereafter, flew the aircraft into a severe 'lee of the mountain downdraft' at an altitude insufficient for recovery. No evidence was found to explain why this particular approach was attempted.

Circumstances:
On a flight from Sverdlovsk to Tashkent when the crew committed errors in handling trim tabs and autopilot, the aircraft entered a dive while flying at a height of 8,400 metres. Control was recovered by the crew at a height of some 6,600 metres. The crew managed to land safely, but the aircraft suffered structural damage during the dive with up to 2.7 g forces. Reported at LED 12SEP70 but can this be correct ? SOC 20MAY71 due to its poor technical condition.
Probable cause:
Loss of control caused by a mishandling of the trim tabs and autopilot system on part of the crew.

Circumstances:
While approaching Timmins Airport, the crew realized that weather conditions were marginal and decided to return to Winisk. This was not possible as the weather worsened at Winisk as well so the crew returned to Timmins and initiated a second approach despite the visibility was below minima. On final, the aircraft was too low and crashed three km short of runway threshold. Both pilots and two passengers were killed while four others were injured. The aircraft was destroyed.
Probable cause:
The pilot made inadequate pre flight preparations for a flight into known marginal weather. The pilot descended below the minimum altitude. The pilot exposed himself and his crew to the effects of fatigue by attempting a flight after a long period of duty.

Circumstances:
The airplane arrived in Kazalinsk at 1020LT and 12 passengers embarked. The aircraft was fully booked and ready for departure when the captain accepted, against retribution, that 12 additional passengers (11 adults and one infant) embarked as well. Some 120 kilos of cargo and 120 kilos of additional baggage were also loaded. After takeoff, while climbing to a height of 200 meters, the airplane adopted a high angle of attack when the tail stalled. Out of control, the airplane crashed 65 meters to the left of the main runway. 25 passengers were injured while one child was killed. A day later, two passengers died from their injuries and two other passengers died few days later. The aircraft was destroyed upon impact.
Probable cause:
The decision of the captain to embark 12 additional passengers was criminal and against all published procedures. Neither the copilot nor the Airport Manager complained about this decision. At the time of the accident, the total weight of the aircraft was 6,484 kilos, some 1,234 kilos above the MTOW, taking into consideration the actual flying conditions. Also, the CofG was far aft and well outside the envelope, which caused the airplane to stall from the tail during initial climb. All additional passengers did not have safety belt.

Circumstances:
On final approach to Barrow, an engine failed. The crew reduced his altitude and attempted an emergency landing. The airplane crash landed and slid for dozen yards before coming to rest few hundred yards short of runway threshold. All 10 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
Engine failure on final approach. The following factors and findings were reported:
- Improper maintenance on part of the maintenance personnel,
- Anti-icing, de-icing system,
- Icing conditions including sleet and freezing rain,
- Engine icing,
- The crew failed to use or incorrectly used the miscellaneous equipment,
- Ice on propeller,
- Airframe ice,
- Complete engine failure,
- Hot air lines to intake air duct loose.

Circumstances:
The airplane landed too far down on a wet runway and was unable to stop within the remaining distance. It overran and lost its undercarriage before coming to rest 132 meters further. All 53 occupants escaped uninjured while the aircraft was written off.
Probable cause:
Wrong approach configuration on part of the flying crew who landed too far down the runway, reducing the landing distance available. At the time of the accident, the runway was wet and the aircraft also suffered aquaplaning.

Circumstances:
The crew started the approach to Nizhnevartovsk Airport by night and marginal weather conditions. Due to erroneous calculations, the aircraft was not properly aligned on the approach path and the captain decided to make a go-around. Six minutes later, he initiated a second approach. On short final, ATC asked the pilot if he has the runway in sight. As the answer was positive, the crew was cleared to land. Less than a minute later, the airplane struck tree tops, stalled and crashed in flames in a wooded area located 1,092 meters short of runway threshold. 32 occupants were injured while 24 others were killed, among them the copilot and a flight attendant.
Probable cause:
It was determined that the propellers went inadvertently into reverse when the crew activated the engine de-icing system. It was later discovered during investigations that there was a conception error on this type of aircraft between the de-icing systems and the thrust reversal systems that could activate simultaneously. Nevertheless, when control was lost, the flaps were deployed in an angle of 17° instead of 38° as prescribed, which was considered as a contributing factor.
