Hindustan Aeronautics Limited (HAL) achieved a major milestone today with the successful maiden flight of the first series production HTT-40 Basic Trainer Aircraft, designated TH-4001, marking a key moment in India’s drive toward self-reliance in defence aviation.
The flight, conducted at HAL’s Bengaluru facility, signifies the transition of the HTT-40 program from prototype development to operational production. The indigenously designed and developed aircraft is set to bolster the Indian Air Force’s (IAF) primary pilot training fleet by replacing ageing trainers.
Powered by a Honeywell TPE331-12B turboprop engine, the HTT-40 features modern avionics, advanced safety systems, and fully aerobatic capability. With an indigenous content level of 56%—expected to rise above 60%, the platform stands as a testament to India’s “Make in India” initiative in the aerospace sector.
The IAF has placed an initial order for 70 HTT-40 aircraft worth ₹6,838 crore, with HAL expected to deliver the first unit by January 2026 and 11 more by March 2026. The aircraft will be produced across HAL’s Bengaluru and Nashik facilities, with the newly inaugurated Nashik line capable of producing eight aircraft per year.
Developed through HAL’s internal funding since 2013, the HTT-40 has accumulated over 900 flight-test hours and is fully compliant with US FAR-23 certification standards. It supports instrument and night flying, ensuring that it meets global benchmarks for pilot training.
The milestone follows the recent inauguration of new production lines for both the Tejas Mk-1A and HTT-40 at HAL Nashik, expanding India’s defence manufacturing ecosystem and creating new employment opportunities.
With the HTT-40 entering the production phase, it is poised to become the backbone of India’s basic flying training program, reinforcing HAL’s reputation as the cornerstone of India’s indigenous defence aerospace capabilities.
