Air India Begins Construction of a New MRO Facility in Delhi
Air India has launched construction of a new aircraft maintenance facility at Indira Gandhi International Airport (IGIA), marking a further step in its efforts to strengthen engineering capabilities and improve operational efficiency.
Announced on 22 October 2026, the project will cover nine acres at the airline’s largest hub. The facility is designed to accommodate one widebody aircraft and one narrowbody aircraft at the same time, allowing Air India to bring several important maintenance functions together at a single location.
The development is expected to improve control over inspections, aircraft defect rectification and cabin maintenance. By integrating these activities, the airline aims to reduce avoidable delays and return aircraft to service more efficiently.
The project also supports Air India’s broader effort to develop greater in-house maintenance capabilities and strengthen operational self-reliance.
How the New Hangar Will Reduce Aircraft Ground Time
Aircraft ground time refers to the period an aircraft remains on the ground rather than operating scheduled flights. Although some downtime is essential for inspections and repairs, delays can increase when maintenance teams, spare parts and technical facilities operate across separate locations.
Air India’s new Delhi hangar is designed to address these operational challenges through three major improvements.
1. Centralised Engineering and Maintenance Operations
The facility will bring key engineering offices and maintenance activities together. This arrangement can improve coordination between technical teams, reduce fragmented workflows and support quicker decisions when aircraft require inspections or repairs.
Centralised operations can be particularly valuable at a major airline hub, where aircraft availability directly affects flight scheduling and network planning.
2. On-Site Spare-Parts Warehouse
The hangar will include a dedicated warehouse for spare parts, providing maintenance teams with more direct access to components needed for repairs.
When a technical issue requires a replacement component, delays in locating, moving or issuing the part can extend the time an aircraft remains grounded. Keeping relevant inventory close to engineering teams can help reduce these delays, subject to parts availability and maintenance requirements.
The arrangement is also expected to improve parts-handling efficiency and reduce associated logistics costs.
3. Dedicated Cabin Maintenance Unit
Air India plans to include a dedicated Cabin Shop for aircraft interior repairs.
Cabin maintenance can involve repairing seats, interior fittings and other cabin-related components. A specialised unit will allow the airline to manage more of this work internally, potentially reducing dependence on third-party vendors and speeding up the resolution of cabin defects.
Together, these improvements are intended to support faster maintenance turnaround and better aircraft availability.
Hangar Designed for Widebody and Narrowbody Aircraft
The new MRO facility will be designed with a 25-metre clear internal height and large column-free spans. These features will provide the space required to accommodate different aircraft configurations and support evolving maintenance requirements.
Its ability to house one widebody and one narrowbody aircraft simultaneously is a notable feature of the project. Widebody aircraft are generally used on long-haul and high-capacity routes, while narrowbody aircraft commonly operate domestic and short- to medium-haul services.
Accommodating both aircraft types within the same facility will give Air India greater flexibility in planning maintenance activities at Delhi.
However, the hangar’s simultaneous aircraft capacity should not be confused with its total maintenance throughput. The number of aircraft it can service over time will depend on maintenance scope, staffing, equipment, spare-parts availability and aircraft scheduling.
Safety and Sustainability Built Into the Project
Aircraft maintenance facilities require stringent safety controls because they handle complex aircraft systems, technical equipment and potentially hazardous materials.
Air India says the new hangar will incorporate advanced fire protection systems and follow strict safety standards.
The project will also follow Indian Green Building Council (IGBC) green-building norms, including provisions for energy and water conservation. These measures align with the airline’s stated environmental, social and governance (ESG) commitments.
For aviation infrastructure, sustainable building practices can help manage resource consumption while supporting long-term facility operations.
What the Project Means for India’s Aviation and Logistics Sector
Air India’s investment has implications beyond aircraft maintenance. Efficient MRO operations are an important part of the wider aviation supply chain, connecting airlines with component manufacturers, spare-parts distributors, engineering teams, technical service providers and airport infrastructure operators.
Better Fleet Availability and Operational Resilience
When aircraft remain grounded longer than expected, airlines may face aircraft substitutions, schedule adjustments and disruptions to connecting services.
A well-integrated maintenance facility can help shorten certain repair and inspection processes, giving airline operations teams more flexibility when managing technical issues.
The actual improvement will depend on how effectively the facility operates after commissioning. Air India has not announced a quantified reduction in ground time or a completion date in its available project announcement.
Stronger Maintenance Supply Chains
The on-site warehouse will make inventory management an important part of the facility’s operating model. Effective spare-parts planning can help reduce maintenance delays, while accurate inventory records can improve visibility into component availability.
As aviation maintenance becomes more data-driven, digital inventory management, predictive maintenance and integrated engineering systems can further support planning and operational control. These are broader industry opportunities, rather than confirmed features of the new Delhi hangar announcement.
Opportunities for India’s MRO Ecosystem
Greater investment in domestic aircraft maintenance infrastructure can support the development of specialised engineering capabilities and aviation support services in India.
For suppliers and logistics providers, maintenance expansion can create demand for aircraft components, inventory management, specialised transportation and time-sensitive parts distribution. The scale of these opportunities will depend on the facility’s eventual operations and procurement requirements.
Air India’s Long-Term Maintenance Strategy
The Delhi project forms part of Air India’s wider effort to strengthen its operational capabilities as it transforms its airline business.
Developing in-house maintenance infrastructure can give an airline greater direct oversight of selected technical activities. It can also help coordinate engineering resources and spare-parts availability more closely with fleet requirements.
The new hangar complements the airline’s broader investment in aviation infrastructure and maintenance capabilities. However, it is important to distinguish the project’s announced objectives from outcomes that have yet to be measured: lower aircraft ground time, reduced maintenance costs and improved fleet reliability will need to be assessed once the facility becomes operational.
Conclusion
Air India’s nine-acre MRO hangar at Delhi Airport represents a significant addition to the airline’s planned maintenance infrastructure. By combining engineering offices, spare-parts storage and cabin repair capabilities, the facility aims to improve maintenance coordination and reduce aircraft downtime.
For India’s aviation and logistics sectors, the project highlights the importance of integrated maintenance infrastructure, inventory availability and operational efficiency. Its longer-term impact will depend on the facility’s commissioning, maintenance capacity and ability to deliver measurable improvements in fleet availability.
As Air India continues to develop its engineering capabilities, the Delhi hangar could become an important part of its strategy to build a more resilient and efficient aviation operation.
