An Embraer jet used by VVIPs including Home Minister Rajnath Singh, BJP president Amit Shah and Congress president Rahul Gandhi has been found by NDTV to have been stripped down for a "major routine overhaul" in a Maharashtra town, allegedly without the regulator's permission.
Taking note of the NDTV investigation, DGCA Director of Airworthiness Pavan Kumar has summoned the executives of Air One, which has been making do with a hangar in Gondia, at an airport which, the national auditor said in 2016, handles no flights even though it is developed.
The Directorate General of Civil Aviation (DGCA) has found that Air One did not have qualified workforce and advanced tools which are required to take apart and reassemble the Brazilian-made Embraer Lineage jet for maintenance.
Gondia, some 1,000 kilometres from Mumbai, does not figure in the Brazilian plane-maker's list of authorised service centres.
Air One has stopped maintenance work on its Embraer for now, people with direct knowledge of the matter said. The DGCA said it will send a team to the Gondia hangar to see whether aviation safety guidelines have been flouted by the air charter firm.

For a comparison of how these fancy planes with bedrooms and luxe lounges on board are maintained by other owners, one only has to look toward the Indian Air Force (IAF), which has a number of these aircraft.
NDTV has learnt that for a third-line inspection - a term used for stripping aircraft - that is needed every 96 months (or 4800 hours), the conditions have to be so sanitised that the IAF flies the aircraft to Brazil.
Industry insiders didn't want to comment but they say it is very unlikely that Air One or any Indian company has the ability or the tools for a third-line inspection, which, according to the manual, involves the "removal of over 400 panels and external items, ailerons, flaps and rudder, inspections, aft tank functionality checks and the replacement of the aft tank bladder along with replacing the flight control cables." It all requires at least a dust-proof environment, which, pictures show, Gondia doesn't provide.

However, NDTV has learnt that work on this very sensitive specialised aircraft started in January, before the DGCA certificate, and the plane was taken there on December 26. While Mr Sharma acknowledges it, he says it took them a month to get the approval.
