Indian Airlines Flight 171 was a scheduled domestic passenger flight that crashed while attempting an emergency landing at Bombay Airport (now Chhatrapati Shivaji Maharaj International Airport) on 12 October 1976 after suffering an uncontained engine failure, killing all 95 people on board. Metal fatigue in the No. 2 engine's 10th stage high-pressure compressor disk had caused it to disintegrate, the resulting fragments severed fuel lines causing fuel to leak into the engine and ignite causing an uncontrolled fire that eventually affected control surfaces leading to a loss of control.

 Accident

Flight 171 was a scheduled domestic passenger flight from Bombay (now Mumbai) to Madras (now Chennai). A Boeing aircraft was originally supposed to make the flight but it developed engine trouble and was replaced with a Sud Aviation Caravelle. Shortly after takeoff from runway 27, Flight 171 suffered a No. 2 engine failure. The crew of Flight 171 immediately turned back to attempt an emergency landing on Bombay Airport's runway 09. With its undercarriage down approximately 1،000 ياردة (3،000 ft; 910 m) from the end of the runway and while at an altitude of 300 أقدام (91 m), the aircraft suffered a loss of control and plummeted into the ground. Everyone on board Flight 171 perished in the accident.

 Cause

A fatigue crack in the tenth stage compressor disc caused a power plant failure which was followed by the bursting of the compressor casing and the cutting of fuel lines that spanned the structure. This caused an intense in-flight fire in the engine bay. It is believed the fire consumed the Caravelle's supply of hydraulic fluid and this was the cause of the aircraft going out of control.
