PURPOSE AND REQUIREMENT DESCRIPTION
The Government is conducting market research to identify potential sources that possess the repair data, expertise, capabilities, and experience necessary to meet qualification requirements for C-5 Moving Island Actuators. C-5 Moving Island Actuators are part of the aircraft secondary flight-control system and control the moving-island section of the slats. The moving islands provide aerodynamic sealing when the slats are retracted and move out of the way when the slats are extended. The C-5 Moving Island Actuators position the slat moving islands over the engine pylons in tandem with slat extension and retraction. The items are critical to the function of the C-5 aircraft slat system. Repair and overhaul require strict control of processes to ensure proper functioning and full design life on the aircraft. Special equipment and tooling identified in the applicable USAF overhaul manual are required to perform this repair. Failure of C-5 Moving Island Actuators could place the aircraft and crew in an extremely hazardous situation due to restrictions in slat movement and damage to critical surrounding components. Such failure could result in asymmetrical slat conditions or a significantly reduced operating envelope. Component failures during critical phases of flight may increase aircrew task saturation and the risk of aircraft mishap. Failure under these conditions could result in loss of life and/or aircraft.
