AAR Allen Services, Inc., a subsidiary of AAR Government Services Inc., was awarded a single-award Indefinite Delivery Contract by the U.S. Army Aviation and Missile Command on September 29, 2025, with a ceiling value of $25.1 million and ultimate completion date of September 30, 2030. The contract covers maintenance, repair, and overhaul services for CH-47 Chinook helicopter cylinder assemblies, specifically identified by National Stock Numbers 1650-01-496-6802 and 1650-01-548-6686. No small business set-aside was utilized for this award. AAR Allen Services will perform work at its facility in Garden City, New York. The original pre-solicitation notice, posted in February 2024, indicated the Army anticipated procuring between 20 and 504 cylinder assembly units over the five-year contract period under North American Industry Classification System code 336413 (Guided Missile and Space Vehicle Manufacturing).
Under this Indefinite Delivery Vehicle, a firm fixed-price delivery order was issued on September 29, 2025, in the amount of $941,238 for the overhaul of CH-47 Chinook cylinder assemblies supporting the CH-47F Block II Modernized Cargo Helicopter program, with completion required by October 31, 2026. This task order falls under the CH-47F Block II Major Defense Acquisition Program, a Category IC acquisition managed through the U.S. Army's Program Executive Office Aviation for modernization and sustainment of the Army's CH-47F Chinook heavy-lift cargo helicopter fleet. AAR Allen Services' established expertise in aerospace component maintenance, repair, and overhaul for military platforms, combined with its prior successful performance under a related $33.2 million CH-47 servo cylinder maintenance contract with the Army Aviation and Missile Command, positions the contractor as a critical supplier within the Army's helicopter sustainment infrastructure.
