In a First-In-Asia, GMR Aero Technic Adopts an Inflatable Hangar

Hyderabad | 23 February, 2021

Hyderabad, February 23, 2021 : The GMR Group has been a pioneer in implementing various innovative solutions across the airports it operates. GMR led Delhi and Hyderabad airports, have been leveraging the best of technologies: E-boarding, Face Recognition trials, Contact – less Self Check-in Kiosks, Self-Bag Drops, Contactless Information Desk etc. to name a few. In continuum with this streak, GMR Aero Technic (GAT), the MRO (Maintenance, Repair and Overhaul) division of GMR Air Cargo and Aerospace Engineering Ltd. (GACAEL), has taken a giant leap in terms of aircraft maintenance and service in Asia, by adopting a new innovative technology in the form of an Inflatable Hangar. GAT is the only MRO in the Asia region to have installed such a hangar. The Inflatable Hangar may be used for multiple purposes including scheduled and unscheduled maintenance, engine or landing gear replacement.

The one bay narrow body Inflatable Hangar is sufficient to take one B737 or A320 series aircraft which will add one additional bay to GAT’s already existing 7 bay capacity. With this additional line, GAT would be able handle additionally 15 to 20 smaller base maintenance checks or 4 to 5 end of lease checks per year.


It takes considerable amount of time to source an available hangar to undertake the unscheduled repairs. On the contrary, an Inflatable Hangar is cost-effective, reduces downtime to a minimum and saves time and money as compared to building a conventional hangar, at the same time catering for all the functionality, safety features and structural stability of the conventional hangar.

The life of an Inflatable Hangar is 10-15 years. It is available in various sizes and made to order. Whereas the construction of a conventional hangar takes more than 18 months, the Inflatable Hangar can be constructed in 3-4 months. The Inflatable Hangar is also portable. It takes just 1-2 months to disassembly and assembly at other location. It is by far the most cost effective & quickest way to add additional capacity as compared to building a conventional hangar or taking similar facility on rent/lease.

The Inflatable Hangar is formed by low pressure tubes aligned parallel to each other forming a "rib-cage" structure. This woven polyester base cloth with PVC coating hangar is both fire-retardant and water-proof. An Automatic Control System will be installed in the hangar, to continuously monitor and control operative parameters. The hangar is designed to withstand wind speeds up to 158.4 km/hr and can handle temperatures from -30 degree Celsius to +70 degree Celsius which makes it a perfect alternative for conventional solid metal hangars which are both expensive and time consuming to build.

Mr. Ashok Gopinath, CEO, GMR Aero Technic, said, “The latest addition of this Inflatable Hangar to our MRO will help us take additional business and support our customers in meeting their timelines and commitments of aircraft operations and redeliveries. Such hangars are used as a proper alternative to conventional hangars by MROs in Europe and GCC for many years now. In the long term, we are looking at adding a couple of more hangars aimed at upgrading to include wide body aircraft capability including painting, certain critical components workshops and military MRO business. GAT has been very proactive in constantly looking at new technologies and adopting them to enhance business needs.”

The Inflatable Hangar will serve as a dedicated base maintenance facility complementing existing facility in GMR Aero Technic, Hyderabad and help in optimizing the already available resources in terms of manpower, tooling, support workshop etc. The Inflatable Hangar is equipped with doors, lighting, fire detection & extinguishing and ventilation system with centralized computer-based monitoring system including remote diagnostics. It is designed and built for regular continuous usage.
