The listed crash cause is human factor. 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.
