The Linear Actuator, NSN: 1680-094-6453GA; PN: SYLC50114/NSN: 1680-00- 400-8271GA; PN: DL1326M164, is an electro-mechanical force input device used to direct air flow in the Air Management System (AMS) on the UH-1N. The Cylinder Assembly, NSN: 1650-01-421- 4776GA; PN: 212-076-005-109/NSN: 1650-01-421-4775GA; PN: 212-076-005-107, translates input
from the pilot/copilot's collective input into the swashplate and ultimately the main rotor blades on the UH-1N. The UH-1N helicopter functions primarily as a light-lift utility platform. It performs missions including airlift of emergency, security, and disaster response forces, emergency evacuation of Government officials, support for school training and testing, airlift for distinguished visitors and transport/security for Intercontinental Ballistic Missile (ICBM) support personnel. Other roles include airborne cable inspections, security surveillance of off-base nuclear weapons convoys, response to search and rescue operations, and medical evacuation and transport. The UH-1N can easily change mission packages to support this diverse set of functions. The capability of flight during inclement weather or nighttime conditions allows it to operate in most situations. The overhauls of the dynamic components are used on the USAF UH-1N helicopter. These components are commercial items and not a military unique application. The Original Equipment Manufacturer (OEM) is Bell Helicopter. The listed components are flight Critical Safety Items (CSI). The UH-1N is unique to the USAF but variants of the H-1 are used by other services, commercial entities, and foreign military customers. There are no other USAF applications. This service will only support the USAF UH-1N fleet.
