This SAE Aerospace Recommended Practice (ARP) describes methods of masking and cleaning commercial aircraft, epoxy and polyester matrix, composite parts prior to their entry into the composites shop, masking and cleaning of on-wing repair areas in preparation for carrying out repairs and wipe cleaning during repair and prior to bonding. It this document is used for the masking or cleaning of materials other than epoxy and polyester matrix thermosetting composite materials, the fitness for this purpose must be determined by the user.

The methods of masking and cleaning described in this document have specific limited application and are not interchangeable. The methods shall only be used when specified in an approved repair procedure or with the agreement of the Original Equipment Manufacturer (OEM) or regulatory authority.

This Technical Specification gives information about technical requirements and qualification procedures of adhesive paste with or without thickening agent for core restoration of aircraft components.

AMS3970/4 specifies the batch release and delivery requirements for film adhesive used for repair. This specification is applicable only when the film adhesive is used as part of the prepreg system as defined in AMS3970 and AMS3970/1.

The PS, AMS3970/3, specifies the batch release and delivery requirements for carbon fiber fabric epoxy prepreg used for repair.

The PS, AMS3970/5, specifies the batch release and delivery requirements for the companion non-structural glass fiber fabric prepreg.
