The Indian Directorate General of Civil Aviation (DGCA) has suspended the licence for Air India's Boeing simulator training centre in Mumbai over an unspecified regulatory lapse, the PTI news agency has reported.

While the details of the shortcoming were not disclosed, sources said a routine DGCA audit revealed discrepancies in the certification of instructors who operate the simulators. All training, including recurrence checks, at the facility have since been halted.

Air India did not respond to ch-aviation's request for comment.

The Mumbai training centre is the smaller of two simulator facilities owned by Air India, with the larger one being the Central Training Establishment (CTE) in Hyderabad.

The ch-aviation fleets module shows the airline's Boeing fleet comprises seven B777-200(LR)s, fourteen B777-300(ER)s, and twenty-seven B787-8s while Air India Express (IX, Delhi International) operates twenty-six B737-800s. The carrier has 140 B737-8s, fifty B737-10s, ten B777-9s, and twenty B787-9s on order from the US manufacturer.
