The SAE Aerospace Information Report (AIR) is intended to be used as a process verification guide for evaluating implementation of key factors in bonded repair of fiber reinforced composite structure in a repair shop environment. The guide will be used in conjunction with a regulatory approved and substantiated repair, and is intended to promote consistency and reliability.

This guidebook will assist in the design and integration of composite commercial aircraft structures that exhibit improved durability, maintainability and repairability. For international use by composite aircraft component designers, this book identifies problems that have occurred with various composite components and provides potential problem-solving recommendations. Written primarily for composite design engineers, Design of Durable, Repairable, and Maintainable Aircraft Composites should also prove valuable to those in structural engineering, materials and processing, product support, advanced product development, systems engineering, technical services, and maintenance operations.

SAE CACRC has produced several standards, each representing the best-practice, recommended minimum training syllabus for the aforementioned target groups. The purpose of this document is to promote the use of these SAE standards, particularly for developing training programs for employee training, qualification in airlines and maintenance organizations, and as reference in regulatory guidance material. It summarizes, as a quick reference, the content of each training document and its relation to and interaction with other training documents. Thereby it allows users to select the appropriate training documents and syllabi to establish a comprehensive, sequential training program build-up customized to the specific needs of the aforementioned functions (see figure). This document does not intend to introduce new training content/syllabus.

To create Guidance on the essential information/data that is needed to correctly assess damage and document the damage. A guidance document is proposed as the initial step in which it is documented what essential information is required for a composite repair with the aim to reduce to number of back and forward communications, improve the documents to define damage such as mapping, damage descriptions, sketches, pictures. CACRC Procedures Task Group will be drafting the document.

Increased use of advanced composite structural materials on aircraft has resulted in the need to address the more demanding quality and non-destructive testing procedures. Accordingly, increased utilization of solid laminate composites is driving changes to airline NDT training requirements and greater emphasis on the application of accurate NDT methods. Modules, including an introduction to composite materials, composite NDI theory and practice, special cases and lessons learned, have been produced in addition to various hands-on NDT exercises. A set of proficiency specimens containing realistic composite structures and representative damage has been designed in order to reinforce teaching points of the course and “test” inspector’s proficiency. Extensive details of the course modules, hand-on exercises and the proficiency specimens are all presented in this report.

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 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.

It is recognized that the structural integrity of repaired composite structures depends upon the capabilities of the individuals who are responsible for performing the repairs. This document is intended to address repairs of composite structure regardless of the type of structure such as marine, wind turbine, automotive, aircraft, or other applications. This certification standard establishes the minimum requirements for training, examining, and certifying composite structure repair personnel. It establishes criteria for the certification of personnel requiring appropriate knowledge of the technical principles underlying the composite structural repairs they perform. Persons certified under this document may be eligible for licensing or certification/ qualification by an appropriate authority, in addition to this industry accepted basic composite repair technician certification.

This document provides general guidelines for showing compliance to the applicable certification requirements associated with the modification or alteration to type design of composite aircraft structure or installation of composite parts on metallic or composite airframes, of all aircraft product types. The types of modifications or alterations that this document is meant to address are: • Modification or alteration of metal or composite baseline structure, necessary to install a cargo or mission equipment pod, antenna, winglets, etc. • Installation of composite parts onto metallic or composite baseline structure, such as the pods, antennas, performance enhancing aerodynamic fairings, radomes, cowlings, interior components, etc.

This SAE Aerospace Information Report (AIR) gives guidelines for the design of local “controlled contamination area” (CCA) which can provide a particle-free zone in a hangar or field environment. These guidelines may be used when performing bonded repairs specified in an approved repair procedure or with the agreement of the Original Equipment Manufacturer (OEM) or regulatory authority.

Individuals who complete the applicable modules aligned with this training document will be able to define the type of damage, define the extent of damage, determine if further inspection is required, evaluate the damage against published allowable damage limits, and provide accurate documentation of the damage. The intended outcome of the training is increased safety such that no aircraft is released with unknown damage and that the aircraft meets continued airworthiness requirements. The goal is to change the culture from damage discovery to damage reporting while also reducing or eliminating flight delays due to incorrect or insufficient information. Teaching levels have been assigned to the curriculum to define the knowledge, skills, and abilities graduates will need. Minimum hours of instruction have been provided to ensure adequate coverage of all subject matter including lecture and practical exercise.
