This Aerospace Recommended Practice (ARP) describes methods of vacuum bagging, a process used to apply pressure in adhesive bonding and heat curing of thermosetting composite materials and metalbond for commercial aircraft parts. If this document is used for the vacuum bagging of other than thermosetting composite materials and metalbond, the fitness for this purpose must be determined by the user. The methods shall only be used when specified in an approved Repair Document or with the agreement of the Original Equipment Manufacturer (OEM).

AMS6885/2 gives specific information about the qualification program for unidirectional carbon fiber tape epoxy repair prepreg capable of curing under vacuum for repair of carbon fiber reinforced epoxy structures. The prepreg system shall include an epoxy film adhesive to be applied in a co-bonding process with the prepreg for solid laminate and sandwich bonding.

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.

This document establishes the minimum curriculum requirements for training, practical assessments, and certifying composite structure repair personnel and metalbond repair personnel. It establishes criteria for the certification of personnel requiring appropriate knowledge of the technical principles underlying the composite structural repairs and/or metalbond they perform. Persons certified under this document may be eligible for licensing/certification/qualification by an appropriate authority, in addition to this industry accepted technician certification. Teaching levels have been assigned to the curriculum to define the knowledge, skills, and abilities graduates will need to make repairs to composite or metalbond structure. Minimum hours of instruction have been provided to ensure adequate coverage of all subject matter including lecture and laboratory.

This is a general curriculum that has been developed to identify the minimum knowledge and skill requirements of a composite and/or metal bond repair technician/specialist. This revision changes the document from an all-inclusive curriculum into a modular set of curricula. Teaching levels have been assigned to the curriculum to define the knowledge, skills, and abilities graduates will need to make repairs to composite or metalbond structure. Minimum hours of instruction have been provided to ensure adequate coverage of all subject matter including lecture and laboratory. These minimums may be exceeded and may include an increase in the total number of training hours and/or increases in the teaching levels. Each curriculum is a subpart of this document. Part 1 is the General Composite Structure Bonded Repair curriculum, independent of the application. Part 2 is the Commercial Aircraft Composite Structure Bonded Repair curriculum.

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.

This document describes a life cycle cost model for commercial aircraft composite structure. The term life cycle cost used herein, refers to the airline costs for maintenance, spares support, fuel, repair material and labor associated with composites after introduction into service and throughout its useful life. This document contains the equations that can be programmed into software which is used to estimate the total cost of ownership aircraft, including structure. Modification costs and operating costs are estimated over a specified life (any period up to 30 years). Modification costs include spares holding, training, support equipment, and other system related costs. Annual operating costs include: Schedule interruption, fuel, spares, insurance, and maintenance. Maintenance costs are separated by scheduled maintenance or unscheduled damage, or can by grouped into the typical organizations of line, shop, and hangar maintenance.

This SAE Aerospace Information Report (AIR) provides information related to machining of composite materials, components and structures. This document is intended to supplement the machining processes and guidelines provided in OEM repair manuals and structural repair manuals. It is not intended to supersede the approved data provided in OEM repair documents.

This is a general curriculum that has been developed to identify the minimum knowledge and skill requirements of a composite and/or metal bond repair technician/specialist. This revision changes the document from an all-inclusive curriculum into a modular set of curricula. Teaching levels have been assigned to the curriculum to define the knowledge, skills and abilities graduates will need to make composite repairs. Minimum hours of instruction have been provided to ensure adequate coverage of all subject matter - lecture and laboratory. These minimums may be exceeded, and may include an increase in the total number of training hours and/or increases in the teaching levels. Each curriculum is a subpart of this document. Part 1 is the basic curriculum independent of product and is the companion to ARP6262 Part 2 is the aircraft specific curriculum and is currently under development and will be released in the next revision to this document.

This SAE Aerospace Recommended Practice (ARP) describes standard methods for restoring damaged core on commercial aircraft sandwich structures. 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. The repair materials shall be defined in the approved repairs referencing these methods.
