Lessors of 20 aircraft to the bankrupt airline Go First have asked the aviation regulator DGCA to deregister them, paving the way for their return. The Directorate General of Civil Aviation (DGCA) has published the details of the lessors and their request 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, according to experts familiar with the process. It is not known whether Go First plans a legal challenge on this.
