The Directorate General of Civil Aviation (DGCA) has published the details of the lessors and their requests on its website.

By law, the DGCA has to start deregistering an aircraft in five working days once a lessor sends a request to do so and publish the details on its website, reports said. It is not known whether Go First plans a legal challenge on this.

In a statement on Tuesday, Go First Airline announced its decision to ground all flights and said it intends to return to the air soon once the problems are solved, specifically the matter of leased spare engines from US firm Pratt & Whitney.

Go First has alleged the US firm did not keep its word on supplying the engines, which forced the airline to ground 50 percent of its Airbus A320neo fleet and subsequently, all operations.
