First TPE331-12B Engine for HTT-40 Trainer Aircraft

Issue: 06-2026

Honeywell has delivered 3 TPE331-12B engines to Hindustan Aeronautics Limited’s (HAL) HTT-40 basic trainer aircraft for the Indian Air Force.

The TPE331-12B engine’s selection for the HTT-40 brings a proven propulsion system to India’s newest trainer aircraft. The HTT-40, HAL’s indigenously developed basic trainer aircraft, is now in production for the Indian Defence Forces and is powered by Honeywell’s TPE331-12B engines. Honeywell will supply the first 16 engines for the fleet, after which HAL will begin local engine assembly and expand in-country repair and overhaul capabilities. Over the coming years, more than 80 engines are planned to support the HTT-40 programme, further building India’s expertise in engine sustainment.
