The DGCA’s review also included an analysis of recent operational data, with a focus on Air India’s wide-body operations, particularly the Boeing 787 aircraft.

DGCA advised the Tata-owned airline to strengthen internal coordination across its engineering, operations, and ground handling units, and to ensure the adequate availability of spare parts to reduce passenger delays.Air India has cancelled 66 flights to be operated with Boeing 787 between June 12 and June 17, the civil aviation regulator said.The statements come days after a London-bound Air India flight crashed within a minute of take-off from Ahmedabad. All but one passenger on board was killed, along with about 30 people on the ground and DNA testing continues to identify victims before the bodies are handed to over to their families.
