The failure was preceded by an ENG#2 stall warning, indications of high vibration, and exhaust gas temperature exceeding limits.
Crew Actions and Landing
In response to the engine malfunction, the flight crew performed an in-flight shutdown of the No. 2 engine. The aircraft executed an air turn back and subsequently made an uneventful landing at Mumbai Airport.

Investigation and Coordination
The government of India has notified the National Transportation Safety Board (NTSB) of the incident. As the state of manufacture of the engine, the NTSB has appointed a U.S. Accredited Representative to assist the government of India in their investigation under the provisions of ICAO Annex 13. All investigative information will be released by the government of India.
