Military airworthiness type certification

Every military aircraft that flies in India must first pass through a single gate. No indigenous fighter, helicopter, or transport can reach production or deployment until an authority signs that it is safe to fly. Only a handful of nations operate such an authority for their own complex combat aircraft.

India is one of them. The Centre for Military Airworthiness and Certification (CEMILAC), a DRDO laboratory, is the country's regulatory authority for military airworthiness, operating through Regional Centres of Military Airworthiness co-located at development and production sites. It joins the United States, United Kingdom, France, Russia, Germany, China, and Japan among nations with this capability.

The difficulty is exhaustive. Every system, line replaceable unit, component, material, and software element on an airborne platform must be individually certified against the armed forces' performance, reliability, and life requirements before a type certificate is issued. This is not a formality — it is thousands of separate judgements, each with lives attached.

CEMILAC has demonstrated it can carry a full programme through. It granted Initial Operational Clearance to the LCA Tejas in January 2011 and Final Operational Clearance in February 2019 — an independent certification of a supersonic fighter with quadruplex fly-by-wire controls, composite structures, and digital avionics. In January 2019, HAL received permission to begin FOC-standard Tejas production, completing the passage from certification to manufacturing. The capability extends to subsystems: MIDHANI's indigenous superalloys for AL-31FP engines were cleared in January 2024, and blended bio-jet fuel for the AN-32 in January 2019. In July 2025, CEMILAC worked with the DGCA on a unified UAV certification framework built on Indian Military Technical Airworthiness Requirements V2.0.

Two structural constraints keep the gate narrow. First, capacity: CEMILAC shares wind tunnels and fatigue rigs with the National Aerospace Laboratories, reports staff shortages in critical certification roles with manpower sanctions pending, and lacks specialised facilities for emerging technologies like AI-integrated avionics and additive manufacturing. Delays follow — the Tejas FOC and the ALH Dhruv engine integration, which ran three years past its December 2006 target, illustrate the pattern.

Second, the framework. Certification runs under DDPMAS-2002, which lacks the procedural documents — comparable to FAA Order 8110.46 or CAR-21 — that define delegated authorities to approved design and production houses, creating uncertainty for Strategic Partner and "Make in India" models.

Closing the gap means deeper testing capacity, a maturing Design Assurance System across industry — over 30 organisations are now registered under DOAS — and procedural frameworks that let certification scale with the programmes waiting on it.
