The U.S. Army Aviation and Missile Command awarded a single-award IDIQ to Honeywell International Inc. on September 28, 2020, for T55-GA-714A aircraft engine overhaul services with a ceiling of $258,664,388.20. The contract carries no set-aside designation and was limited in the solicitation to Honeywell International Inc. and Columbia Helicopters.

Work is performed at Honeywell's Aerospace - Phoenix Division facility in Phoenix, Arizona. The IDIQ requires depot-level labor, facilities, tooling, test equipment, and materials to maintain and overhaul T55-GA-714A engines. The originating solicitation specified a minimum of 40 engines and maximum of 380 engines over the five-year base period, including 40 engines for foreign military sales. The contract runs through September 28, 2025.

Recent task-order activity reflects sustained demand across the CH-47F Modernized Cargo Helicopter (Block II) program and general rotorcraft sustainment. Honeywell has issued multiple delivery orders valued between $455,252 and $44.1 million for engine overhaul, inspection, and T55-GA-714A engine delivery work.
