Circumstances:
During the takeoff roll, the crew failed to realize that the aircraft was not properly aligned when the left main gear struck the snow covered shoulder of the runway. The aircraft lost speed and the crew did not abandon the takeoff procedure so liftoff was completed too late. After rotation, the aircraft struck the ILS antenna, crash landed, hit a ditch and came to rest. All 65 occupants were evacuated safely while the aircraft was damaged beyond repair.

Circumstances:
The airplane was completing a charter flight and departed Buenos Aires-Aeroparque-Jorge Newbury Airport at 2253LT bound for San Carlos de Bariloche. While on a night ILS approach to runway 28, the crew encountered technical problems with the ILS reception and the captain decided to initiate a go-around procedure. Few minutes later, the crew started the descent prematurely with a rate of descent of 2,200 feet per minute instead of the required 750 feet per minute. This caused the aircraft to descend below the minimum descent altitude until it collided with ground about 21 km east of the airport. All five crew members and 41 passengers were killed while 33 other occupants were injured. The aircraft was destroyed.
Probable cause:
The accident was caused by the collision of the aircraft with the ground during the final approach to Bariloche runway after an improper and premature descent which was below safety limits. The accident can be attributed to a procedural error by the crew during the final approach in that they abandoned the ILS procedure, an action strongly and unduly influenced by the interruption of the VOR signal and also probably by the state of mind of the pilot-in-command.

Circumstances:
The twin engine airplane departed San Carlos de Bariloche Airport at 1534LT on a flight to Río Gallegos with intermediate stops in El Bolsón and Comodoro Rivadavia. It was carrying a crew of four and two passengers, Mr. Ulderico Carnaghi, Governor of the Santa Cruz Province and his wife who just attended the 7th Snow Festival in san Carlos de Bariloche and were flying back to Patagonia. While descending to El Bolsón Airport, the crew encountered poor weather conditions when the airplane struck the slope of Mt Paleta located 18 km north of El Bolsón. The wreckage was found four days later at an altitude of 1,995 meters. The aircraft was destroyed and all six occupants were killed.

Circumstances:
The airplane departed El Palomar Airbase in Buenos Aires on a flight to San Carlos de Bariloche, carrying 47 soldiers and their family members. There were also two Uruguayan citizens on board. While approaching San Carlos de Bariloche Airport in marginal weather conditions, the airplane struck the slope of Mt Lopez located about 34 km west of runway 11 threshold. The wreckage was found few hours later and none of the 52 occupants survived the crash.
Probable cause:
It is believed that the accident was the consequence of a controlled flight into terrain after the crew initiated the descent prematurely when he did not have sufficient ground assistance. It is possible that the crew was unaware of the strength of the wind in the area when the accident occurred, winds that caused the aircraft to divert from the prescribed approach path.

Circumstances:
The aircraft took off from Ezeiza Airport at 1554LT on a scheduled flight direct to San Carlos de Bariloche with Comodoro Rivadavia as alternate. Six crew and fifty-five passengers were aboard. Clearance was granted by the Regional Centre Control Area for an IFR flight outside airways, with 1 200 metres as safety height as far as Neuquén and 2 400 metres up to the destination aerodrome. The aircraft carried out routine communications with the airport control tower and with the approach control office until it reached Lobos, where it was authorized to use telegraphy. From that moment there was no further information available concerning the flight. It was later established that at 1645 hours the aircraft had crashed 25 km southeast of Bolivar. All occupants were killed and the aircraft was destroyed by the impact and the fire which broke out subsequently.
Probable cause:
The aircraft disintegrated in flight due to breakage of parts of the left wing followed by the falling off of the tail section when the equipment was subjected to stresses above those envisaged by the manufacturer. This was brought about as a direct result of the pilot's decision to attempt to cross a cold surface front under turbulent conditions of extreme severity. The following were contributing causes:
- The pilot's recklessness in descending on a track well below the minimum safety flight altitude established for this type of operation,
- The absence in the flight plan of a forecast showing the intensity of the meteorological phenomena encountered,
- Inadequate ope rational dispatch of the aircraft.
