Air France Flight 030, a Boeing 747-128, F-BPVD, was a scheduled passenger flight which originated at Chicago's 0'Hare International Airport at 1820 e.d.t., on August 17, 1970. Its destination was Orly Airport, Paris, France, with an intermediate scheduled stop at Montreal, P.Q., Canada. At departure from Montreal, 174 revenue passengers, two infants, and a crew of 17 were aboard the flight.
The flight from Chicago to Montreal was nomal in every respect. The takeoff from Montreal at 2226 was routine; however, approximately 9 minutes after takeoff, at 2235 at an altitude of 5,600 feet m.s.l., a separation of the second-stage turbine disk rim of the No. 3 engine occurred,and pieces penetrated and ruptured the high-pressure turbine case and associated engine cowling . The separation of the turbine disk rim resulted in a localized fire in the upper forward portions of No. 3 engine.
A fire warning, which came on simultaneously with the turbine failure, terminated after both containers of fire extinguishing agent were discharged. The No. 3 engine was shut down and the flight diverted to John F. Kennedy International Airport, Nev York, where it landed safely at 0004 (August 18). There were no injuries to passengers, crew, or persons on the ground.
