São Paulo, Brazil: Shortly after takeoff from Viracopos-Campinas International Airport, Aerolíneas Argentinas Flight 322 , a De Havilland Comet, registration LV-AHR, crashed into some treetops past the end of the runway and exploded into flames. The plane was a De Havilland Comet 4, registration LV-AHR, that had just taken off on the second leg of an international flight that started in Buenos Aires and after São Paulo would continue on to Port of Spain (Trinidad and Tobago) before finishing in New York City.
The plane took off normally and climbed to 100 meters before falling slightly and clipping some trees, reducing speed until the plane fell to earth taking all 52 souls on board with it. There were no survivors. The weather service in Brazil noted that while the sky was completely overcast, weather did not play a part in the crash while the Argentinian government investigators discovered that the first officer was seated in the left side of the flight deck, which implied that the captain was training the first officer, coaching him from the first officer’s seat.
Argentina concluded that the plane came down due to inadequate training of the first officer using proper IFR (Instrument Flight Rules) flying procedures.
