2015-10-15 Mahan Air Boeing 747-300 engine falls apart near Tehran


During climb-out parts of the high pressure turbine of an engine seperated and fell down into a Tehran suburb. The 747 managed to return to land.

The 29 year old 747 just took off from Mehrabad Airport (runway 29R) when its right inner engine #3 (Type: CF6-50E2) partly disintegrated during climb.

The entire lower pressure tubine –  just aft of the engine cowlings – section broke loose and fell to the ground in a western suburb of the city. Fortunately no person on the ground was harmed.

Energetic engine debris hit the lower fuselage resulting in substantial damage. Shrapnel also damaged many parts of the wing, flap canoe, and lower fuselage of the aircraft.

The pilots discontinued their climb. After receiving a warning message from engine #3 and an oil pressure warning from engine #4, both right wing engine s were shut down.

The pilots made a safe landed back at Mehrabad Airport on the remaining two portside engines about 10 minutes later.
