6、 and is a Five-Year Review and update of this specification. 1. SCOPE 1.1 Purpose This specification details requirements and procedures for the detection of defects in aircraft and engine components during maintenance and overhaul operations. 1.1.1 This specification contains three appendices which
7、 provide additional guidance designed to supplement the information contained in the main body of the document. Because the guidance contained in the appendices is either subjective in nature or may have alternative acceptable approaches, it is not intended to be binding unless specifically invoked
8、by the Cognizant Engineering Organization (CEO), an Original Equipment Manufacturer (OEM), or other contractual agreement. Personnel performing inspections to this specification should be familiar with the guidance and exercise good judgment if variance from this guidance is necessary. The following
9、 appendices are included: 1.1.1.1 Appendix A - Guidelines for Design, Procurement and/or Fabrication of Penetrant Systems 1.1.1.2 Appendix B - Guidelines for Assessment of Background Fluorescence 1.1.1.3 Appendix C - Processing and Inspection of Drum Rotors/Deep Well Spools and Other Complex Parts w
10、/Limited Accessibility 1.2 Processing of parts and interpretation and evaluation of indications revealed by this inspection process shall be accomplished by qualified personnel having experience with fluorescent penetrant inspection. Qualification of personnel shall be in accordance with ATA 105, NA
11、S 410, EN 4179, or ASNT SNT-TC-1A. 1.3 Basis of Application This process has been used typically by maintenance and overhaul facilities to inspect aircraft and engine components and associated accessories when fluorescent penetrant inspection is specified, but usage is not limited to such applicatio
12、ns. SAE INTERNATIONAL AMS2647F Page 2 of 42 1.3.1 There are areas in this document that may require specific direction from the OEM or CEO. This direction shall be provided in the part material specification for each part in the following areas: 1.3.1.1 Etching Requirements If not specified, etching
13、 will not be performed (see 3.3.6). 1.3.1.2 Cleaning Requirements If not specified, solvent cleaning using Alcohol, Acetone or Methyl Ethyl Ketone (where locally approved) (see 3.4) or an approved QPL-AMS-2644 solvent cleaner/remover is acceptable. 1.3.1.3 Surface Coating Removal If not specified, p
14、arts may be inspected with the surface coating intact (see 3.3.4, 3.3.4.1 and 3.3.4.2). 1.3.1.4 Penetrant Sensitivity Level If not specified, Sensitivity Level 3 penetrants shall be used on all airframe hardware and components and Sensitivity Level 4 penetrants shall be used on all Major Rotating co
15、mponents of engines and Auxiliary Power Units. 1.3.1.5 Penetrant Method If not specified, Type I, Methods A, C, or D may be used except for major rotating engine hardware which shall only be inspected using Type I, Methods C or D. 1.3.1.6 Drying If not specified, air-circulating oven drying shall be
16、 used. If other heat-assisted drying methods are used, they shall be approved by the CEO. 1.3.1.7 Developer If not specified, dry developer (Form a) shall be used. 1.3.1.8 Inspection Coverage If not specified, the areas described in 3.4.12.1 shall be inspected. If inspection of areas requiring speci
17、al equipment or techniques (i.e., UV-A borescopes or light sources, special material application or removal devices, part handling fixtures, part masking, etc.) is necessary, detailed instructions shall be provided by the OEM part or material specification. When specific areas of parts require inten
18、sified inspection scrutiny, due to either their critical nature or past history of failure, this information shall be included in the repair or inspection manual or document. 1.3.1.9 Post-Inspection Cleaning If not specified, parts shall be cleaned and dried after inspection to remove inspection res
19、idue which may be detrimental to subsequent operations or impair the structural or functional integrity of the part. 1.3.1.10 Processing Parameters Shall be as specified within this document. If approved by the OEM, different processing parameters, other than those specified herein, may be used. 1.3
20、.1.11 Acceptance Criteria This specification does not provide accept/reject criteria for specific components. Where no accept/reject criteria are specified by the CEO, all relevant indications shall be regarded as suspect and shall not be accepted without review by the CEO. SAE INTERNATIONAL AMS2647
