This SAE Aerospace Standard (AS) establishes the requirements for port preparation, installation, and removal procedure for AS5550 fitting assembly and AS5865 fitting reducer assembly, and is applicable when specified on engineering drawings, or in procurement documents.
Port preparation tooling consolidated into Table 3C. Addition of alternate tooling numbers in Tables 1B, 2B, and 3C. Correct Table 2A, Port Number 24 Installation Torque to 1900 through 2100 lbf.in. Add user definition requirement if torque values desired are other than those listed in Tables 1A or 2A. Update Section 5 to improve port cavity definition. Update 6.2.4 and 7.2.4 to recognize use of the sealants/primers and discourage use of Zinc Chromate primer. Update 6.2.5 and 7.2.5 for installation torque limits. Correction of references.
