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 A: ITEM IDENTIFICATION

SECTION B: JUSTIFICATION FOR ESTABLISHING A QUALIFICATION

REQUIREMENT

The C-5M Flap Asymmetry brake is used when an asymmetrical condition in the flap system is detected to stop the system to prevent asymmetrical aerodynamic loads and prevent further damage to the system. The two flap asymmetry brakes are capable of preventing the entire flap system from moving. These parts are critical to the emergency shutdown of the flap system on the C-5M aircraft.

C-5M Flap Asymmetry brake repair requires strict control of processes to ensure adherence to quality control and testing requirements. Special tooling is required for the repair capability and special equipment is required for testing the flap asymmetry brake once repaired, consistent repair processes are needed to ensure that the flap asymmetry brake is repaired and will be operable and reliable in the event of an asymmetrical condition in the flap system in flight.

Failure of the flap asymmetry brake would either cause the flaps to become inoperable without having an asymmetrical condition, or would allow the flaps to continue operating under an asymmetrical condition which increases the risk of severe damage to the system and inequal aerodynamic loading across the wings, especially in times of flight with high flap usage, like takeoff and landing.
