BUSINESS EXPLAINERAUTHOR REVIEW COPY · 19 SEP 2026
The Indian companies that build, supply and keep aircraft flying
Research date: 19 September 2026
Disclosure: This article is for education and research only. It is not investment advice or a recommendation to buy or sell any security.
When we see an aircraft, we usually notice the airline name on its body. But the airline is only one part of the story.
Behind that aircraft are businesses making special metals, engine parts, wings, electrical systems and software. Other businesses bring these systems together. Maintenance companies then support the aircraft throughout its working life.
As a research analyst, my starting question is simple: What does the company actually do, and where does its work fit into the aircraft?
In this article, I will explain that chain using Indian listed companies, private businesses and India-based joint ventures. We will cover the main stages, from materials to maintenance. This is a broad map with selected verified companies, not a census of every Indian supplier.
Concept illustration created for this article. It does not depict a particular company's products or a technical assembly drawing.
1. First, separate the aircraft business from the airline business
An airline sells travel and cargo capacity. An aircraft manufacturer builds and supports aircraft. A component supplier makes something that goes into an aircraft or its systems.
These are different businesses.
A company can supply a small but important engine part without manufacturing the complete engine. Another can develop aircraft software without owning a factory that builds planes.
Our focus here is aircraft manufacturing and support, covering civil and military programmes. Most examples concern fixed-wing aircraft. A helicopter example is identified where relevant. Airports, airline stocks, space-launch vehicles, missiles and drones are outside this article's main scope.
Two terms will help:
OEM: original equipment manufacturer. In this context, the company responsible for an aircraft, engine or major system.
- MRO: maintenance, repair and overhaul. This means inspecting, maintaining and repairing aircraft, engines and components.
2. Where does India fit into the global aircraft industry?
India participates at several levels: aircraft programmes, component production, engineering and maintenance.
For one indication of that participation, Airbus said on 6 March 2026 that its annual sourcing from India had increased from US$500 million in 2019 to over US$1.5 billion. It also referred to more than 100 Indian suppliers supporting its programmes. This is Airbus's own sourcing disclosure, including components and services—not the size of India's entire aircraft industry. 1
The useful question is therefore more specific than “Is aviation growing?”
Which part of the work is happening in India, which entity performs it, and what stage has that programme reached?
3. How the aircraft value chain works
The following map is a way to organise the industry. Companies often work across more than one stage. The examples do not form one shared supply chain or all supply the same aircraft.
An explanatory map based on the company sources in this article. Engineering supports several stages rather than occurring only once.
A. Aircraft manufacture and final assembly
Hindustan Aeronautics Limited — listed
HAL works across aircraft manufacture, engines, avionics, repair and overhaul. Its role includes building and supporting aircraft, rather than supplying only one type of part. Its business is military-led; it should not be described as an Indian equivalent of a large commercial-airliner manufacturer. 2
Tata Advanced Systems Limited — unlisted, Tata Sons subsidiary
TASL is the Indian contractor for the Airbus C295 military transport programme. Its responsibilities cover parts, structures, final assembly, testing and fleet support. Final assembly means bringing the major sections and systems together and checking the finished aircraft. TASL's published programme scope includes 40 aircraft to be manufactured and assembled in India; that is not a statement that 40 have already been delivered. TASL is not Tata Motors or another listed Tata company. 3 4
B. Special metals and engine components
Before an engine part is machined, the right material has to be produced. Superalloys are specialised metal alloys used where heat and other operating demands are severe. Casting forms a part by pouring molten metal into a mould. Machining removes material to reach the required shape and dimensions.
Mishra Dhatu Nigam Limited (MIDHANI) — listed
MIDHANI supplies specialist materials. Its FY2025–26 operating update reports superalloy and titanium-alloy supplies for indigenous aero-engine programmes. It therefore belongs near the beginning of the chain: supplying material from which finished components can be made. Its business also serves other industries, so all MIDHANI sales should not be treated as aircraft sales. 5
PTC Industries → Aerolloy Technologies — listed parent, operating subsidiary
Aerolloy is PTC Industries' aerospace-materials subsidiary. Its work includes titanium, superalloys and investment castings. These support engine and structural applications. The entity distinction matters: PTC is the listed company; Aerolloy is the operating subsidiary. 6
There is also a stage distinction. PTC's Q1FY2027 release describes its new Airbus agreement in terms of development, qualification, industrialisation and future supply. It should not be presented as proof that every part under that agreement is already in regular production. 7
Azad Engineering — listed
Azad makes precision components for aircraft systems and aero-engines. Its FY2025–26 report describes aircraft-system work including auxiliary power, actuation, hydraulic and structural components. An auxiliary power unit supplies onboard power separately from the main propulsion engines. 8
Existing business and new programmes need to be read separately. The same report describes the Rolls-Royce programme as still under qualification, with first shipments expected during FY2027. Qualification means demonstrating that the product and process meet the customer's requirements. An expected shipment is not an achieved shipment.
Godrej Aerospace — Godrej & Boyce's aerospace business
This business sits within Godrej & Boyce and the Godrej Enterprises Group. Its work includes aero-engine components and aircraft systems such as actuators and steering-related assemblies. An actuator converts a command into physical movement. This is a component-and-system role, not evidence that Godrej manufactures a complete certified aircraft engine. 9
It is not a separately listed “Godrej Aerospace” stock, and listed Godrej Industries should not be substituted for this business. The cited AMCA-related agreement concerns development work; it is not proof of serial deliveries for that future aircraft programme.
Bharat Forge — listed
Bharat Forge's aerospace business covers engine, structural and landing-gear components. Landing gear is the system that supports an aircraft on the ground and during take-off and landing. Its role extends beyond a generic association with defence. 10
Its FY2025–26 report also discusses future manufacturing additions. Those plans should be kept separate from facilities already operating and components already delivered.
C. Structures and precision manufacturing
The airframe is the aircraft's main structural framework. Wings, body sections and the upright tail structure are examples of structural work. A supplier may make an individual part, a subassembly or a larger integrated section.
Dynamatic Technologies — listed
Dynamatic makes aircraft structural parts and assemblies, including flap-track-beam assemblies. These assemblies form part of the wing's flap-support mechanism. It supplies structural work for aircraft programmes rather than manufacturing the entire aircraft. 11
Aequs Limited — listed
Aequs' aircraft portfolio includes precision components for engines, landing systems, wings, body structures and interiors. Its manufacturing ecosystem includes machining, forging, surface processing and assembly, with some capabilities organised through joint ventures. Its own business also extends beyond aerospace. 12
A naming update matters here: Aequs is listed in this 2026 map, with NSE symbol AEQUS. It should not be carried forward as an unlisted example from older articles. 13
Mahindra Aerostructures Private Limited — unlisted operating subsidiary
Mahindra Aerostructures makes aircraft parts, subassemblies and structures. Its existing work includes commercial-aircraft components for Airbus. It is a private operating company within the Mahindra group, not a separately traded aerostructures stock. 14 15
The group's 31 August 2026 announcement about new A320-family fuselage-skin work targets deliveries from 2028. A fuselage skin is an outer panel of the aircraft body. Existing supply and that future delivery programme must not be mixed together.
Tata Boeing Aerospace Limited — India-based joint venture
TBAL, the TASL–Boeing joint venture, makes Boeing 737 vertical-fin structures and Apache helicopter fuselages. A vertical fin is the upright tail structure; a fuselage is the main aircraft body. The 737 is a civil fixed-wing example, while Apache is a military helicopter example. TBAL does not manufacture the complete aircraft in either case. 16
Larsen & Toubro — listed parent; manufacturing business unit
L&T's Precision Engineering and Systems business handed over LCA Mk1A wing assemblies to HAL, as reported in its July 2025 presentation. This is an example of a major aircraft section being supplied to the final aircraft manufacturer. It is military-aircraft work inside the wider listed L&T group, not a separately listed “L&T Aerospace” company. 17
JK Maini Global Aerospace — Raymond's aerospace subsidiary
This business makes precision-machined aircraft components and assemblies, including work for engines, landing gear and structures. The current entity is JK Maini Global Aerospace; it contains the former aerospace business of Maini Precision Products following the 2025 restructuring. The listed parent is Raymond Limited, not Raymond Lifestyle or Raymond Realty. 18 19
D. Wiring, electronics and aircraft systems
The structure gives an aircraft its physical form. Electrical and electronic systems connect equipment, process information and help pilots monitor and control the aircraft. Avionics is the term used for aircraft electronic systems.
Rossell Techsys — listed
Rossell Techsys makes wiring and interconnect systems, electrical panels and related equipment for aerospace and defence customers. A wiring harness is an organised group of wires and connectors. These connect aircraft equipment and systems. 20
Use the correct entity: Rossell Techsys, not Rossell India. Its May 2026 presentation describes commercial-aerospace entry as an opportunity still being evaluated. The verified positioning here is mainly defence-aerospace wiring and systems.
Bharat Electronics Limited (BEL) — listed
BEL's contracted Tejas Mk1A work includes airborne electronics such as flight-control computers, air-data computers and head-up displays. These systems support control, information processing and cockpit information. 21
The cited order was announced in December 2021 for execution over 2023–2028. It supports BEL's programme role, not a claim that every unit has been delivered. The release also credits the relevant government design agencies; manufacturing a system and owning every part of its design are different roles.
Hical Technologies Private Limited — unlisted
Hical works on electrical and electromechanical components, including motors and transformers, alongside precision mechanical assemblies and integration. Its official portfolio includes aircraft-interior applications. These are supporting components and assemblies rather than whole aircraft. Its broader website also covers space and other applications, which should not all be counted as aircraft activity. 22 23
Data Patterns (India) Limited — listed
Data Patterns' military-aircraft products include cockpit displays and radar-warning electronics. Its FY2025–26 report also describes a Mission Management and Display Computer developed for the LCA Air Force Mk2 programme. This is an aircraft-specific electronics role, but a development-programme product does not mean the aircraft has entered fleet service or that all units are in serial production. 33
E. Engineering and software
A physical component starts with drawings, calculations, software, testing and documentation. Engineering providers support that work. They may be paid for engineering effort, a project or an ongoing support arrangement, depending on the contract.
Cyient Limited — listed
Cyient's engineering portfolio covers aircraft structures, engines, avionics, software, interiors and aftermarket support. It helps customers design, test and support systems. This does not mean it builds a complete engine or aircraft. Cyient Limited and Cyient DLM are different listed entities; this entry concerns Cyient's engineering services. 24
L&T Technology Services (LTTS) — separately listed subsidiary of L&T
LTTS provides aircraft-system and structural engineering, wiring design, verification, testing and certification-support documentation. It supports the customer's engineering process; it is not the aviation regulator or final certifying authority. Keep this services business separate from L&T's wing-manufacturing example above. 25 26
F. Maintenance after the aircraft enters service
Building an aircraft is only part of the work. Aircraft in service require inspections, replacement parts, repairs and heavier maintenance. MRO businesses support availability and safe operation within their approved scope.
AI Engineering Services Limited (AIESL) — unlisted government company
AIESL provides aircraft and engine maintenance, including line maintenance and major maintenance for aircraft types such as Boeing, Airbus and ATR. Line maintenance concerns work around regular operations; heavier maintenance involves more extensive inspections and repairs. 27
AIESL belongs to AI Assets Holding Limited, the government holding company. It should not be described as a Tata-owned Air India subsidiary today. 28
GMR Aero Technic — an operating brand/division
The operating MRO division described in the FY2024–25 report belongs to GMR Air Cargo and Aerospace Engineering Limited. It provides aircraft maintenance, structural repairs, component work and painting. Its listed-group connection is indirect through the GMR Airports group. 29
This needs careful naming: the report separately identifies a similarly named GMR Aero Technic Limited subsidiary engaged mainly in MRO consultancy. A familiar brand name is not always the legal entity performing the work.
Air Works India (Engineering) Private Limited — unlisted operating company
Air Works provides line and heavy maintenance, painting and interior work for civil and defence aircraft. Its disclosed base-maintenance examples include Airbus A320, Boeing 737 and ATR aircraft. 30
Adani Enterprises' 11 March 2026 filing confirms that Adani Defence Systems & Technologies had completed increasing its stake in Air Works to 99.98%. The listed connection is therefore through Adani Enterprises; Air Works itself is not a separately listed stock. This completed transaction supersedes the older proposed-acquisition description. 31
G. Tools and infrastructure behind the production line and hangar
Some companies support aircraft without supplying a part that flies.
Unimech Aerospace and Manufacturing — listed
Unimech makes specialised tools used to manufacture and maintain aircraft engines and airframes, along with ground-support equipment and precision assemblies. A maintenance tool can be essential to work on an engine without becoming part of that engine. This tooling role should not be confused with manufacturing complete engines or aircraft. 34
Taneja Aerospace and Aviation — listed
Taneja's FY2025–26 report describes technical support and aviation infrastructure, including hangars and buildings leased to an MRO organisation. Its role illustrates the difference between providing maintenance infrastructure and performing the tenant's maintenance work. The report discusses further manufacturing and MRO opportunities, but those opportunities should not be presented as completed operations. 35
4. What “listed” and “unlisted” actually mean in this map
There are three distinct situations:
| Situation | Example | What the reader should understand |
|---|---|---|
| The operating company itself is listed | HAL, Dynamatic, Azad, Aequs, Rossell Techsys | The named company has its own listed equity. That does not mean all its revenue comes from aircraft. |
| Aircraft activity is inside a listed group | PTC–Aerolloy; Raymond–JK Maini; Adani Enterprises–Air Works | The operating subsidiary and the listed parent are different entities. Ownership, consolidation and business contribution need separate examination. |
| A private company, unlisted group business or JV does the work | TASL, TBAL, Godrej Aerospace, Hical | A familiar group name does not establish a direct listed-stock equivalent. |
LTTS is another useful distinction: it is a subsidiary of L&T and is itself separately listed.
This is why I begin with the legal entity and its actual work. A group logo alone is not enough.
5. An order is the beginning of a process, not the final result
A new aircraft contract can pass through several stages:
Agreement → development → qualification → production readiness → regular deliveries → customer payment
The path differs by product and contract. A signed agreement may involve several steps before repeat production.
The International Aerospace Quality Group's 9145 framework addresses product-quality planning and production-part approval. Its production-approval concept asks whether the process can consistently meet requirements at the customer's required production rate. In simple terms: can the supplier produce the right part repeatedly, at the required pace? 32
That is why words such as “selected”, “approved”, “qualified”, “commissioned” and “delivered” should not be used interchangeably.
Conceptual business model, not a timetable, forecast or accounting policy for any named company. Contract terms can include advances and milestone payments.
6. How do these businesses earn money—and where can cash get stuck?
The following is my analytical framework, not a forecast for a particular company.
| Business | What the customer pays for | Questions I would ask |
|---|---|---|
| Materials and castings | Qualified material or cast components | How much input material becomes an accepted product? How much is rejected or reworked? |
| Machined parts and structures | Components and assemblies meeting the specification | Is production repeatable? Are machines sufficiently used? Are deliveries accepted on time? |
| Electronics and systems | Hardware, integration, testing and support | What is the programme stage? Who owns the design? What support obligations remain? |
| Engineering | Design, development, testing or support work | How is the contract priced? Are skills available? Does the project require rework? |
| Aircraft manufacture | Aircraft and contracted life-cycle support | Are the major systems available? What approvals and customer milestones remain? |
| MRO | Inspections, labour, repairs, parts and maintenance packages | Are the right skills, parts and maintenance slots available? How long does the aircraft stay in the hangar? |
A simple hypothetical example shows the cash issue.
Suppose a supplier purchases metal and performs machining today. The customer accepts the parts later and pays after the agreed credit period. The supplier may have money tied up in raw material, unfinished parts and customer bills before it receives cash.
Working capital is the money needed to support that operating cycle. Receivables are amounts customers owe. A customer advance may reduce the funding need; delayed acceptance or payment may increase it.
The exact outcome depends on the contract. A growing order pipeline alone does not tell us whether cash generation will improve.
7. What would I watch as a research analyst?
I would organise the work around eight questions:
- What exactly is supplied? A material, a finished part, an assembly, engineering work or maintenance?
- Which legal entity does the work? The listed company, a subsidiary, a joint venture or an overseas operation?
- Which customer programme is involved? Civil aircraft, military aircraft, an engine programme or another application?
- What has actually happened? Agreement, qualification, first delivery or regular production?
- How concentrated is the business? What happens if one major customer slows production?
- How reliably can it deliver? Look at acceptance, quality, rework, delivery performance and the customer's required rate.
- How much cash and investment are needed? Examine equipment spending, inventory, receivables and customer advances.
- How material is aircraft work to the company? A diversified group can have a real aircraft business that is still a small part of its overall operations.
Programme delays, certification requirements, quality failures, specialised-material availability, currency movements and customer concentration can affect these businesses differently. Exposure to the same sector does not create identical economics.

8. What I want readers to take away
India's aircraft ecosystem includes far more than the company assembling the aircraft.
MIDHANI supplies materials. Component and structure manufacturers turn materials into approved parts and assemblies. Electronics and engineering businesses support the systems. HAL and TASL participate at the aircraft-programme level. MRO operators support aircraft after they enter service.
My approach is to follow that work step by step: what is made, who makes it, which programme uses it, and how the business converts that work into cash.
A sector map helps us understand businesses. Evaluating any investment requires separate company-level financial, risk and valuation work.
