Circumstances:
The twin engine aircraft departed San José-Tobías Bolaños Airport in relative good weather conditions. While climbing to an altitude of 6,000 feet, the aircraft struck the slope of the White Peak (2,438 meters high) located about 20 km southeast of the airport. The wreckage was found about 600 meters from the summit and all 23 occupants were killed. At the time of the accident, the visibility was good but some atmospheric turbulences were reported in the vicinity of the mountains.
Probable cause:
Loss of control caused by atmospheric turbulences. At the time of the accident, the crew was tired which was considered as a contributing factor as well as the fact that the operator failed to issue a valid flight safety program.

Circumstances:
En route from Tyumen to Ufa, while cruising at an altitude of 10,600 meters, the fire warning light came on, indicating smoke in the rear cargo compartment. The presence of smoke on board was confirmed but the crew was unable to identify the source of fire. The crew was cleared to initiate an emergency descent and to divert to Pervouralsk Airport. On final approach, the situation deteriorated on board and as the captain realized he could not reach the airport, he attempted an emergency landing in a snow covered area. Upon landing, the aircraft bounced twice, struck an irrigation equipment, went out of control and crashed 3 km from the Pervouralsk Airport. Four crew members and 23 passengers were killed while all other occupants were rescued.
Probable cause:
A short-circuit occured in an electrical installation located in the rear compartment of the aircraft, due to the overheating of a cable with faulty isolation.

Circumstances:
On approach to Villa Gesell Airport, the crew decided to abandon the approach, followed a circuit and eventually decided to land on the opposite runway. After takeoff on the wet runway 10, the aircraft was unable to stop within the remaining distance. It overran, lost its nose gear and right main gear and came to rest few dozen meters further, bursting into flames. All 90 occupants were quickly evacuated before the aircraft would be completely destroyed by fire.
Probable cause:
Improper use of controls on part of the crew caused the aircraft to overrun after landing. Marginal weather conditions were considered as a contributing factor.

Circumstances:
While approaching Port Vila following an uneventful flight from Lenakel, all three engines failed due to fuel exhaustion. The pilot attempted an emergency landing when the aircraft struck coconut trees and crashed in a pasture. The aircraft was damaged beyond repair and all occupants were rescued.
Probable cause:
Engine failure caused by fuel exhaustion. It is believed that the fuel selector was positioned on the main fuel tanks which were empty at the time of the accident while fuel remained in the auxiliary tanks.

Circumstances:
En route from Palembang to Jakarta, while cruising at an altitude of 9,500 feet, the right engine failed. As the crew was unable to maintain the assigned altitude, luggages and cargos were jettisoned but the aircraft continued to descent. Eventually, the crew was forced to ditch the aircraft that crashed in the Banten Bay, few km offshore. Seven people were rescued while nine others including both pilots were killed.
Probable cause:
It is understood that the takeoff weight on departure from Palembang was 18,192 lb, which was over the 16,160 lb maximum takeoff weight. The weight of two ground fire extinguishers and a GPU which were carried on board as cargo were probably underestimated.

Circumstances:
During approach, a fire erupted in the wheel well of the 22-year old airplane. The fire burned thru the hydraulic lines rendering the a, b, and standby hydraulic systems inoperative. The crew landed the airplane using the emergency manual reversion flight control system. However, the airplane was unable to stop on the runway because of the previous failures of the check valves in the backup hydraulic accumulator pressure systems for the #2 thrust reverser and the inboard pair of wheel brakes. During the 2 minutes rollout, the airplane traversed 14,000 feet, overran the runway end, and collided with a concrete structure which collapsed the nose gear. The airplane had recently undergone a 'C' check during which the operator's mechanics failed to observe and repair an electric wire which had been chafing against a hydraulic line. On the accident flight the energized wire arced, punctured the line, and ignited the escaping hydraulic fluid. The hydraulic check valves had failed earlier due to mechanical wear.
Probable cause:
Failure of the operator's maintenance personnel to detect an electrical wire which had chafed against a hydraulic line and which eventually arced causing a leak in the hydraulic line and subsequent fire and hydraulic system failure. In addition, previous wear of check valves in the backup hydraulic systems prevented the airplane from stopping on the runway. A contributing factor was the airplane manufacturer's inadequate guidance for maintaining the hydraulic components.

All 70 occupants were rescued, 40 of them were injured, 21 seriously. For unknown reasons, the spoilers were not deployed after touchdown.

Circumstances:
During arrival for an ILS runway 21R approach, the aircraft encountered icing conditions for about 9-1/2 minutes. As the aircraft was vectored for the approach, the Seattle ARTCC controller used an expanded radar range and did not provide precise positioning of the aircraft to the final approach course. The flight crew attempted to continue on a steep, unstabilized approach for a landing. Recorded radar data showed that the aircraft was well to the right of the ILS course line and well above the glide slope as it passed the outer marker/final approach fix (faf). It did not intercept the localizer course until it was about 1.5 mile inside the faf. Also, it was still well above the ILS glide slope were recorded altitude data was lost when the aircraft was abt 2.5 miles from the airport. The tower had closed, but the controller saw the aircraft in a higher than normal rate of descent in a wings level attitude. Before reaching the runway, the aircraft nosed over and crashed in a steep descent. There was evidence that ice had accumulated on the airframe, including the horizontal stabilizers, which may have resulted in a tail plane stall. All six occupants were killed.
Probable cause:
The flightcrew's decision to continue an unstabilized instrument landing system (ILS) approach that led to a stall, most likely of the horizontal stabilizer, and loss of control at low altitude. Contributing to the accident was the air traffic controller's improper vectors that positioned the airplane inside the outer marker while it was still well above the glideslope. Contributing to the stall and loss of control was the accumulation of airframe ice that degraded the aerodynamic performance of the airplane.
