Honeywell Aerospace has committed to delivering all 16 engines for the HTT-40 trainer aircraft to Hindustan Aeronautics Limited (HAL) by the first half of 2027. The company also aims to complete the technology transfer by the 2029 deadline, according to Matt Milas, president of defence and space at Honeywell Aerospace. After initial delays due to supply chain issues, Honeywell delivered three turboprop engines to HAL in June 2026, with a fourth engine handed over shortly after. The company plans to double the number of engines delivered by the end of 2026, with four more engines scheduled for delivery.
The contract, signed in 2022 and valued at approximately $100 million, includes the supply and manufacture of 88 TPE331-12B engines and kits, along with maintenance and support services. Under the agreement, Honeywell will supply 16 engines directly, while HAL will manufacture the remaining units following the technology transfer. Honeywell has emphasized its close collaboration with HAL, noting significant work done in India for customization and new engine controllers for the latest version of the TPE engine used in the IAF trainer.
Despite earlier delays caused by supply chain disruptions, including a catastrophic fire at a supplier's facility, Honeywell has addressed these issues and established replacement supply arrangements. The company has diversified its supply sources globally and made investments to strengthen its supply base. Honeywell also plans to expand its presence in India's defence and aerospace sectors, exploring opportunities in resilient navigation, counter-drone systems, and other technologies.
