1972 Andes Flight Disaster - The Crash

The Crash

On 13 October 1972, a Uruguayan Air Force twin turboprop Fairchild FH-227D was flying over the Andes carrying Old Christians Club rugby union team from Montevideo, Uruguay, to play a match in Santiago, Chile. The trip had begun the day before, when the Fairchild departed from Carrasco International Airport, but inclement mountain weather forced an overnight stop in Mendoza, Argentina. At the Fairchild's ceiling of 9,000 metres (30,000 ft), the plane could not fly directly from Mendoza, over the Andes, to Santiago, in large part because of the weather. Instead, the pilots had to fly south from Mendoza parallel to the Andes, then turn west towards the mountains, fly through a low pass (Planchon), cross the mountains and emerge on the Chilean side of the Andes south of Curico before finally turning north and initiating descent to Santiago after passing Curico.

After resuming the flight on the afternoon of Friday 13, October, the plane was soon flying through the pass in the mountains. The pilot then notified air controllers in Santiago that he was over Curicó, Chile, and was cleared to descend. That proved to be a fatal error. Since the pass was covered by the clouds, the pilots had to rely on the usual time required to cross the pass (dead reckoning). However, they failed to take into account strong headwinds that slowed the plane and increased the time required to complete the crossing. They were not as far west as they thought they were and, as a result, the turn and descent were initiated too soon, before the plane had passed through the mountains, leading to a controlled flight into terrain.

Dipping into the cloud cover while still over the mountains, the Fairchild soon crashed on an unnamed peak (later called Cerro Seler, also known as Glaciar de las Lágrimas or Glacier of Tears), located between Cerro Sosneado and Volcán Tinguiririca, straddling the remote mountainous border between Chile and Argentina. The plane clipped the peak at 4,200 metres (13,800 ft), neatly severing the right wing, which was thrown back with such force that it cut off the vertical stabilizer, leaving a gaping hole in the rear of the fuselage. The plane then clipped a second peak which severed the left wing and left the plane as just a fuselage flying through the air. One of the propellers sliced through the fuselage as the wing it was attached to was severed. The fuselage hit the ground and slid down a steep mountain slope before finally coming to rest in a snow bank. The location of the crash site is 34°45′54″S 70°17′11″W / 34.765°S 70.28639°W / -34.765; -70.28639, in the Argentine municipality of Malargüe (Malargüe Department, Mendoza Province).
