SQS Repair Moving Island Acutators Signed

SOURCE PRE-QUALIFICATION REQUIREMENTS

RMSC C: The part requires engineering source approval by the design control activity in order to maintain the quality of the part. Existing unique engineering skills, and repair knowledge by the qualified source(s) require repair of the part by the approved source(s). The approved source(s) retain repair knowledge, or technical data that are not economically available to the government, and the data or knowledge is essential to maintaining the quality of the part. An alternate source must qualify in accordance with the design control activity's procedures, as approved by the cognizant government engineering activity, AFLCMC/WLSEAB (C-5 Galaxy Division).

SECTION B: JUSTIFICATION FOR ESTABLISHING A QUALIFICATION

REQUIREMENT

The C-5 moving island actuators position the slat moving islands over the engine pylons in tandem with extension and retraction.
C-5 moving island actuators repair requires strict control of processes to ensure proper functioning and full design life on aircraft. Special equipment is required to perform this repair. Failure of C-5 Flap moving island actuators could place the aircraft and crew in an extremely hazardous situation due to restrictions in slat movement as well as damage to critical components in the surrounding area. This could lead to asymmetrical conditions between slats or dramatically reduced operating envelope. Flight safety histories indicate that aircrew task saturation as a result of component failures dramatically increases the risk of an aircraft mishap if they occur in critical phases of flight. If this failure occurs under these conditions there is a risk of loss of life and/or aircraft.
