A recent Indian defence committee has recommended increasing private sector participation in military aircraft manufacturing to enhance the Indian Air Force’s capabilities. The committee, led by the defence ministry’s top bureaucrat, submitted its report to Defence Minister Rajnath Singh, who has directed that the recommendations be implemented promptly. The report emphasises the need for private companies to work alongside Defence Public Sector Undertakings (DPSUs) and the Defence Research and Development Organisation (DRDO) to achieve self-reliance in aerospace manufacturing. It suggests implementing short-, medium–, and long-term measures to expedite the production of Light Combat Aircraft (LCA) variants, including Mk-1, Mk-1A, and Mk-2, to address delays and strengthen the IAF’s operational readiness.

India’s aerospace and defence sector has undergone significant transformation in recent decades, evolving from a predominantly state-controlled domain to increasingly embracing private sector participation. Fighter jet production, a critical component of national defence, has traditionally been the preserve of public sector undertakings (PSUs) like Hindustan Aeronautics Limited (HAL). However, with the government’s push for indigenisation, self-reliance, and modernisation under initiatives like “Make in India,” the private sector is emerging as a vital player in this high-stakes industry. This article examines the intricacies of how private companies contribute to India’s defence capabilities and what lies ahead for this evolving partnership.

Historical Context

India’s journey into fighter jet production began in the mid-20th century, heavily reliant on foreign technology and licensing agreements. The 1960s saw HAL commence production of the Soviet-designed MiG-21 under license, marking the start of India’s aircraft manufacturing journey. Over the years, HAL expanded its portfolio, producing aircraft like the Jaguar, Mirage 2000, and Su-30 MKI, all under similar arrangements with foreign OEMs. These efforts established HAL as the cornerstone of India’s defence aviation industry, supported by other PSUs and the Defence Research and Development Organisation (DRDO).

The push for Indigenous fighter jet development gained momentum with the HF-24 Marut, designed by German engineer Kurt Tank in the 1960s. However, the Light Combat Aircraft (LCA) Tejas program, initiated in the 1980s by the Aeronautical Development Agency (ADA) with HAL as the production partner, represented a significant leap towards self-reliance. The Tejas, inducted into the Indian Air Force (IAF) in 2016, showcased India’s ability to design and build a modern fighter jet, albeit with substantial reliance on imported components.

Historically, private sector involvement in fighter jet production was minimal. The defence sector’s strategic importance, high capital requirements and restricted access to advanced technology confined manufacturing to PSUs. While effective in establishing a foundational aerospace industry, this PSU-centric model faced limitations in scalability, innovation, and meeting the IAF’s growing demands, setting the stage for private sector inclusion.

Policy Changes Enabling Private Sector Participation

A series of progressive policy reforms have driven the shift towards private sector involvement in defence manufacturing, including fighter jets. Launched in 2014, the “Make in India” initiative sought to bolster domestic manufacturing and reduce import dependency, with defence identified as a priority sector. This program encouraged private companies to participate in defence production by fostering a conducive business environment and promoting collaborations with global players.

A pivotal policy change was the liberalisation of Foreign Direct Investment (FDI) in defence. Previously capped at 26%, the FDI limit was raised to 74% under the automatic route in 2020, with provisions for up to 100% on a case-by-case basis for critical technologies. This opened doors for foreign OEMs to invest in India, often in partnership with private Indian firms, facilitating technology transfer and capacity building.

The Strategic Partnership (SP) Model, introduced in the 2017 Defence Procurement Procedure (DPP), marked another milestone. Designed to foster long-term collaborations between private Indian companies and foreign OEMs, the SP Model identifies private firms as Strategic Partners in manufacturing major defence platforms, including fighter aircraft. The selection process emphasises financial stability, technical expertise, and manufacturing capabilities to create a robust domestic defence industrial base.

Revisions to the DPP further supported this shift. The DPP 2016 introduced the “Buy (Indian-IDDM)” category—Indigenously Designed, Developed, and Manufactured—prioritising equipment with at least 40% Indigenous content. Offset clauses in defence contracts, mandating foreign vendors to invest a percentage of the contract value in India, have also incentivised partnerships with private companies. These policies collectively signal a departure from the PSU monopoly, inviting private sector innovation and investment.

Aviation Maintenance, Repair, and Overhaul (MRO) India

India’s aviation sector is expanding remarkably, positioning the country as one of the largest aviation markets in the world. With rising air travel demand, the MRO industry is expected to witness significant growth, projected to reach a value of around $1 billion by 2025. The increasing number of domestic and international flights, the rise of low-cost carriers, and the burgeoning middle class are major contributors to this growth. Airlines are prioritising maintenance and repair services to ensure operational efficiency and safety.

Key Indian Players. Several key players dominate the Indian MRO industry, each contributing to its development. Air India Engineering Services Limited (AIESL), a subsidiary of Air India, provides comprehensive MRO services for both Air India and third-party airlines, offering airframe maintenance and component support. The Indira Gandhi Institute of Aeronautics (IGIA) plays a crucial role in workforce training through its partnerships with airlines and MRO providers. GMR Aero Technic, a part of the GMR Group, operates from Hyderabad and offers maintenance, repair, and overhaul services. Hindustan Aeronautics Limited (HAL), a state-owned entity, specialises in aircraft maintenance, particularly for military aircraft. The TATA Group has entered the MRO sector through TATA Advanced Systems, focusing on military and commercial aircraft maintenance.

Challenges Faced by the MRO Industry in India. Despite its promising growth, the Indian MRO sector faces several challenges. Infrastructure development remains a significant issue, as many MRO facilities require upgrades to meet global standards. The industry also suffers from a shortage of skilled technicians and engineers, necessitating targeted efforts to attract and train talent. High import duties on aircraft spare parts increase costs for MRO providers, making it challenging to source necessary materials at competitive rates. Additionally, navigating complex regulatory compliance requirements can be resource-intensive for MRO operators. The following factors collectively hamper the growth of an indigenous MRO industry, making Indian airlines reliant on foreign facilities for maintenance.

- OEM Aftermarket Monopoly. Original Equipment Manufacturers (OEMs) dominate the aftermarket, restricting independent MRO players through intellectual property (IP) control, high consultancy fees, and restrictions on direct part sales. OEMs also use pricing strategies and exclusive contracts to limit competition.

- Contractual & Offset Clause Issues – Airlines and OEMs impose conditions in aircraft purchase/leasing deals, such as mandatory maintenance at designated (often foreign) MRO facilities. Offset clauses, especially in defence aviation, usually remain unimplemented, limiting local MRO capabilities.

- Infrastructure Shortcomings. Limited land allocation for airport MRO hangars increases logistics costs. Training infrastructure is also inadequate, with many institutes lacking access to aircraft for hands-on learning.

- Lack of Access to Credit. MRO is capital-intensive, and post-pandemic financial strains have made credit access difficult. High collateral demands further restrict expansion.

- Post-pandemic Demand-Supply Mismatch. While India anticipated MRO growth, post-2021 tax reforms, oversupply due to global pandemic disruptions, and supply chain constraints had hindered expected expansion.

- Taxation & Duty Issues. Despite the reduction of GST on MRO services, high tax rates on spare parts deter growth. Complex customs classifications also result in excessive duties, while the inverted duty structure discourages local manufacturing. Additionally, Indian airports charge royalties on MRO revenue, increasing operational costs.

Emerging Trends. Several emerging trends are shaping the future of the Indian MRO industry. The government has proactively supported this sector through initiatives like the National Civil Aviation Policy and the “Make in India” campaign, which encourage domestic manufacturing and services. Digital transformation is another key trend, with MRO providers increasingly leveraging data analytics and IoT to improve operational efficiency and predictive maintenance. Indian companies are also forming partnerships with global MRO players, gaining access to advanced expertise, technology, and best practices to enhance service quality.

Future Prospects. Looking ahead, the future of the Indian MRO industry appears promising. The continuous rise in air traffic is expected to drive sustained demand for maintenance services, creating new opportunities for existing players and new entrants. Investment opportunities abound in MRO facilities, workforce development, and advanced technologies. As India continues to cement its position as a key player in the global aviation market, strategic initiatives from government and private sector investments will likely shape a more robust and competitive MRO industry.

Recommendations for Strengthening India’s MRO Sector. Key challenges must be addressed to enhance India’s Maintenance, Repair, and Overhaul (MRO) industry and make it competitive globally. The sector needs investment, regulatory support, and improved infrastructure. The following short-term and long-term measures are recommended.

- Establish a Nodal Agency for MRO Regulation. A dedicated regulatory body should oversee policies, manage inter-ministerial coordination, and implement industry reforms. The agency should promote technological innovation (AI, predictive analytics, drones) and encourage R&D for indigenous technology. Offset management must ensure foreign investments contribute to capacity and technology development. Efforts should be made to expand India’s global MRO outreach and foster strategic partnerships with OEMs. Strengthen human resource development through industry-academia collaborations and international exchange programs.

- Leverage low-IP-control areas as Entry Points. Indian MRO should focus on line maintenance, structural repair, avionics, and electrical work before progressing to high-IP areas like engine maintenance. Partnering with Tier-I global MROs can expand expertise and market reach.

- Develop Infrastructure and Encourage OEM Collaborations. Self-sufficiency in spare parts manufacturing is crucial, as spares constitute 55% of component MRO and 80% of engine MRO costs. Government support through Production Linked Incentives (PLI) and joint ventures with FAA/EASA-certified MROs can boost domestic production.

- Address OEM Monopoly and Strengthen Alternatives. OEMs dominate aircraft maintenance through restrictive contracts and data control. India should promote alternatives like Surplus Parts (Used Serviceable Materials), Designated Engineering Representatives (DER) Repairs, and Parts Manufacture Approval (PMA). India should seek bilateral agreements to promote global acceptance of DGCA certifications.

- Introduce Capital Investment Incentives. The government should offer tax credits on capital expenditures, PLI incentives for components and spares, lower duties/taxes on Indian-made aviation parts, and state-level incentives for electricity and amenities to attract foreign MRO investments.

- Adopt a Public-Private Partnership (PPP) Model. MRO facilities require high capital investment and long break-even periods. Government-owned, Privately Operated (GOPO) models can optimise public MRO capacities like AIESL and HAL.

- Civil-Defence MRO Convergence. Leverage underutilised defence MRO capacity (e.g., HAL) to support civil aviation needs. Absorb skilled defence personnel into the civil MRO workforce.

- Rationalise Customs Duty, GST, and Land Rentals. Reduce high GST and customs duty on aircraft parts to match competitors like Malaysia and Singapore. Extend duty exemptions to MRO-imported aircraft parts. Lower AAI land lease rentals to make MRO operations cost-effective.

- Enhance Human Capital Development. Establish industry-linked aviation training programs. Government-supported scholarships and exchange programs can create a skilled workforce.

- Recognise MRO as Infrastructure. Including MRO services in India’s Harmonized Master List of Infrastructure Sub-sectors will enable tax benefits, foreign investment, and financial incentives.

Conclusion

India’s aviation MRO market is poised for significant expansion, driven by rising air traffic, government initiatives, and cost advantages. However, challenges such as high taxation, regulatory complexities, and infrastructure gaps hinder its full potential. India must streamline policies, enhance local capabilities, and attract global investments to capitalise on opportunities. Strengthening the domestic supply chain and fostering skilled labour will further boost competitiveness. With strategic reforms and industry collaboration, India can emerge as a global MRO hub, reducing dependence on foreign facilities and fostering self-reliance. The sector’s growth is vital for the broader aviation ecosystem, supporting economic development and technological advancement.
