In short
- CEMILAC is the certification authority for military airworthiness in India, responsible for design and type approval of military aircraft, systems and stores.
- DGAQA is the quality-assurance authority that inspects and assures conformance during production, provides inspectorate sign-off and clears stores for acceptance.
- The two roles are complementary: CEMILAC certifies that an approved design is airworthy, while DGAQA assures that what you actually manufacture conforms to that certified design.
- Approval rests on documentary evidence: design and configuration records, process and inspection records, concession and deviation histories, and full material traceability.
- A configured ERP that holds configuration, traceability, inspection and concession records makes inspectorate sign-off and audits routine rather than a documentation hunt.
Two authorities, two distinct jobs
Indian defence aerospace suppliers operate under a regulatory framework that often confuses newcomers because two bodies are involved, each with a different mandate. Understanding the division of labour is the first step to navigating approval efficiently. The Centre for Military Airworthiness and Certification, known as CEMILAC, is the certification authority for military airworthiness. The Directorate General of Aeronautical Quality Assurance, known as DGAQA, is the quality-assurance authority. Both operate under the Ministry of Defence, and both must be satisfied for flight hardware to reach service.
The simplest way to hold the distinction is this. CEMILAC answers the question, is this design airworthy and fit to fly. DGAQA answers the question, does the item you actually built conform to that certified design and to the required quality. One is about the design and its type certification; the other is about production conformance and acceptance. A supplier needs to satisfy both, and the evidence each demands overlaps but is not identical.
For a Bangalore supplier feeding HAL, DRDO laboratories, BEL or a defence programme directly, these approvals are not optional paperwork. They are the gate through which parts and systems pass into military use. Getting the documentation discipline right early is what turns a slow, correction-heavy approval into a predictable one. Our DGAQA and CEMILAC compliance software guide maps these requirements to concrete workflows.
CEMILAC: certifying airworthiness
CEMILAC's role centres on airworthiness certification. When a new military aircraft, aero-engine, system, or store is designed or when an existing one is significantly modified, CEMILAC evaluates the design against airworthiness requirements and, when satisfied, issues certification. This is fundamentally a design-assurance activity. It looks at whether the design is sound, whether it has been substantiated by analysis and test, and whether it can be safely operated in service.
For a component or sub-system supplier, involvement with CEMILAC typically comes through the design authority or the prime, but the supplier still carries obligations. You must build to the certified design standard, control any changes through the proper channels, and provide the substantiation data for the parts and processes you are responsible for. When a deviation from the certified design is unavoidable, it cannot simply be absorbed on the shop floor; it must be raised, assessed and formally dispositioned so the airworthiness of the whole is not quietly compromised.
This makes configuration management the beating heart of CEMILAC compliance. Every part must be tied to the exact approved design standard, every change must be traceable to an authorisation, and the as-built configuration must be reconcilable against the certified as-designed configuration. When these threads are managed in disconnected documents, reconciliation becomes a manual ordeal. When they live in a configured system, the as-built to as-designed comparison is a report. Our aerospace traceability software is built to hold exactly this genealogy.
DGAQA: assuring quality and clearing stores
Where CEMILAC certifies the design, DGAQA assures the production. DGAQA is responsible for quality assurance of military aeronautical stores, from raw material through manufacture to final acceptance. It operates through resident and visiting inspectorate staff who review quality systems, witness key inspections and tests, evaluate documentation, and ultimately provide the sign-off that clears stores for acceptance into service.
For the supplier, DGAQA involvement is continuous and practical rather than occasional. The inspectorate expects a functioning quality system, controlled processes, and complete, retrievable records for every item offered. When an item is presented for acceptance, the supporting evidence must be ready: the inspection records, the process records for any special processes, the material certificates, the calibration status of the equipment used, and the disposition of any non-conformances or concessions. The inspectorate sign-off is granted against this documentary package, not against assurances.
DGAQA approval is therefore an ongoing discipline of evidence readiness. Suppliers who keep this evidence in binders and spreadsheets find every acceptance an anxious search; suppliers whose aerospace QMS software holds it find the package assembles itself. This is also where a strong non-conformance and concession process matters, because the inspectorate scrutinises how deviations were identified, assessed and cleared before accepting the store.
The approval path in practice
While every programme differs, the approval path for a defence supplier follows a recognisable sequence. Understanding it helps you prepare the right evidence at the right time rather than reacting to inspectorate requests. The table below outlines the typical stages and where each authority is involved.
| Stage | Primary authority | Supplier focus |
|---|---|---|
| Design and type certification | CEMILAC | Build to certified design standard, provide substantiation data for your scope |
| Quality-system assessment | DGAQA | Demonstrate a functioning, controlled quality system and process capability |
| Production and process control | DGAQA | Capture inspection, special-process and traceability records continuously |
| Concession and deviation handling | DGAQA with CEMILAC where design is affected | Raise, assess and formally disposition every deviation with evidence |
| Inspectorate acceptance and sign-off | DGAQA | Present a complete documentary package for each item offered |
| In-service and modification | CEMILAC and DGAQA | Control changes and maintain configuration and traceability over life |
The through-line is documentation. At every stage, approval rests on the ability to produce complete, consistent, retrievable records that tie the physical item back to its certified design and prove how it was made and inspected. A supplier that treats records as a live output of its production system moves through these stages far more predictably than one that assembles evidence reactively. Our ERP for defence PSU suppliers is configured around this exact flow.
The records DGAQA and CEMILAC expect you to hold
Both authorities ultimately assess you on documentary evidence, so it is worth being explicit about what that evidence comprises. A defence supplier should be able to produce, on demand and without reconstruction, a defined set of records for any item. When these are fragmented across people and spreadsheets, gaps appear precisely when scrutiny is highest. The core record streams are:
- Configuration records tying each part to its certified design standard and revision, with the as-built configuration reconcilable to the as-designed.
- Material traceability linking every batch to its raw-material certificates and its onward genealogy into finished stores.
- Process records for manufacturing and special processes, proving controlled parameters and qualified operators and equipment.
- Inspection and test records including first article results, in-process checks and final acceptance data.
- Calibration records proving all measuring equipment used was in control and in date.
- Concession, deviation and non-conformance records showing how every departure from the standard was identified, assessed, authorised and cleared.
- Change and modification history so the authority can trace every authorised change through the item's life.
The demand is not just that these records exist but that they are consistent with one another and instantly retrievable. An inspectorate that finds an inspection record referencing an obsolete drawing, or a shipped item whose concession cannot be located, will withhold sign-off. This integrity between records is exactly what a single configured platform enforces, and where disconnected documents fail. Our first article inspection software and calibration and gauge management capabilities keep two of these streams provably current.
Where suppliers commonly stumble
Certain difficulties recur across defence suppliers preparing for DGAQA and CEMILAC approval, and most trace back to record management rather than manufacturing capability. Recognising them early saves months. The most common is a broken configuration thread: parts built to a superseded standard because a design change did not propagate to the shop floor, discovered only when as-built and as-designed configurations are reconciled at acceptance. The fix is not more diligence but a system where the released standard is the only one available to work against.
A second recurring stumble is concession sprawl. Deviations get handled informally to keep production moving, and the formal disposition trail is thin or missing. When the inspectorate asks how a departure was authorised, the answer is uncomfortable. A disciplined, system-enforced non-conformance and concession workflow, where nothing ships without a recorded disposition, closes this gap. A third is calibration and record lapses that surface only under inspectorate scrutiny, the same discipline problem that afflicts special-process shops.
The unifying insight is that these are evidence-integrity problems, not effort problems. Suppliers do the work; they struggle to prove it consistently. That is precisely the problem a configured ERP solves, and why building approval readiness on a system of record pays back across every acceptance and audit. Elite Tech configures this discipline for defence suppliers across Karnataka through our aerospace ERP implementation services.
How an ERP holds the evidence both authorities demand
Elite Tech Corporation is a Bengaluru-based Zoho Advanced Partner that configures Zoho and builds custom apps on AWS. We do not sell our own ERP; we implement a platform shaped around the specific evidence DGAQA and CEMILAC expect, so that inspectorate sign-off and airworthiness reviews draw on records the system already holds. The aim is simple: make the compliance record a by-product of running the factory, not a separate documentation exercise.
A platform configured for defence airworthiness ties every part to its certified design standard for configuration control, and reconciles as-built against as-designed automatically. It links finished stores back through operations, operators and equipment to raw-material certificates for full traceability. It routes concessions, deviations and non-conformances through assessment, authorisation and verified closure, so no item ships without a recorded disposition. It manages calibration schedules and holds inspection and first article records. And it timestamps approvals so the audit trail shows who cleared what and when. For suppliers running broader operations, our aerospace and defence ERP in Bangalore brings all of this into one system.
Because the same platform runs production, procurement and quality, evidence readiness becomes continuous. When an item is offered for acceptance, its documentary package assembles from live records rather than being hunted down. When the inspectorate or CEMILAC asks a question, the answer is a retrieval, not a search. For a defence supplier, that turns DGAQA and CEMILAC approval from a recurring ordeal into a routine your system sustains, letting your engineers focus on the hardware rather than the paperwork. You own the configuration and data throughout, with no lock-in to a proprietary product.
Key Takeaways
- CEMILAC certifies military airworthiness at the design and type level, while DGAQA assures production conformance and provides inspectorate sign-off for acceptance.
- The two authorities are complementary: one asks whether the design is airworthy, the other whether your built item conforms to that certified design.
- Configuration management is central; the as-built configuration must be reconcilable to the certified as-designed standard, with every change authorised.
- Approval rests on retrievable, mutually consistent records: configuration, traceability, process, inspection, calibration and concession histories.
- Most supplier difficulties are evidence-integrity problems, such as broken configuration threads and informal concessions, not manufacturing shortcomings.
- A configured ERP makes the documentary package for each item a live output of production, turning sign-off and audits into retrievals rather than searches.
Frequently Asked Questions
CEMILAC, the Centre for Military Airworthiness and Certification, is the Indian certification authority for military airworthiness. It evaluates the design of military aircraft, aero-engines, systems and stores against airworthiness requirements and, when satisfied, issues certification, making it fundamentally a design-assurance authority.
DGAQA, the Directorate General of Aeronautical Quality Assurance, is the Indian quality-assurance authority for military aeronautical stores. It inspects and assures conformance during production through its inspectorate and provides the sign-off that clears stores for acceptance into service.
CEMILAC certifies that a design is airworthy and fit to fly, which is a design-level activity. DGAQA assures that the item you actually manufacture conforms to that certified design and to required quality, which is a production-level activity. Suppliers must satisfy both.
In general, CEMILAC is concerned with the certified design standard your component must meet, while DGAQA assures and accepts your production against that standard. The exact involvement depends on the item and programme, but a supplier of flight hardware typically has obligations to both.
Because CEMILAC certifies a specific design standard, every part must be tied to that approved standard and every change authorised and traceable. The as-built configuration must be reconcilable to the certified as-designed configuration, or the airworthiness of the assembly cannot be assured.
Inspectorate sign-off is the DGAQA acceptance granted, through its resident or visiting inspectorate staff, when an item offered for acceptance is supported by a complete and consistent documentary package. It clears the store for acceptance into service and is granted against evidence, not assurances.
The core records include configuration records tying parts to the certified design, material traceability, process and special-process records, inspection and first article results, calibration records, and concession, deviation and non-conformance histories. All must be retrievable and consistent with one another.
A concession or deviation is a formally authorised departure from the certified design or specification. It cannot be absorbed informally on the shop floor; it must be raised, assessed for its effect on airworthiness, authorised through the proper channel and recorded, so acceptance is granted with full knowledge of the departure.
The most common problems are broken configuration threads, where parts are built to a superseded standard, and concession sprawl, where deviations are handled informally without a clear disposition trail. Both are evidence-integrity problems that a system-enforced workflow resolves.
A configured ERP ties parts to their certified design standard, reconciles as-built to as-designed, holds traceability, inspection, calibration and concession records, and enforces that nothing ships without a recorded disposition. It makes each item's documentary package a live output, turning sign-off and audits into retrievals.
No. Certification and inspectorate acceptance are granted by DGAQA and CEMILAC under the Ministry of Defence. Elite Tech configures Zoho and builds custom AWS apps that hold and organise the records these authorities require, so suppliers present a complete, consistent documentary package and go in prepared.
Yes. Elite Tech Corporation is a Bengaluru-based Zoho Advanced Partner serving aerospace and defence suppliers across Karnataka and India, including firms working with HAL, DRDO, ISRO and BEL. We configure and implement rather than sell a proprietary ERP, so you own your configuration and data.
Conclusion
For Indian defence aerospace suppliers, DGAQA and CEMILAC approval is less a test of manufacturing skill than of documentary discipline. CEMILAC needs assurance that the design is airworthy and that you build to it; DGAQA needs proof, item by item, that what you produced conforms and was made and inspected under control. Both rest on records that must be complete, consistent and instantly retrievable, and the suppliers who struggle almost always do so because their evidence is fragmented, not because their work is poor. Elite Tech Corporation closes that gap by configuring Zoho and building custom AWS apps around the exact records these authorities demand, so configuration, traceability, inspection, calibration and concession evidence flows from daily operations. Approval then becomes a routine your system sustains, freeing your team to focus on the hardware that keeps aircraft flying safely.
