120-102A Incorporation of Electrical Wiring Interconnection Systems Instructions for Continued Airworthiness into an Operator’s Maintenance Program (Including Change 1)

 On November 8, 2007, the Federal Aviation Administration (FAA) published the Enhanced Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS/FTS) final rule. The intent of the rule is to help ensure the continued safety of commercial airplanes by improving the design, installation, and maintenance of electrical wiring systems. Title 14 of the Code of Federal Regulations (14 CFR) part 121, § 121.1111, and part 129, § 129.111 include requirements for operators to revise their maintenance programs to include instructions for continued airworthiness (ICA), which include inspections and procedures for the electrical wiring interconnection systems (EWIS). This advisory circular (AC) only addresses the EWIS requirements and provides guidance accordingly. The current edition of AC 120-97, Incorporation of Fuel Tank System Instructions for Continued Airworthiness into Operator Maintenance or Inspection Programs, provides guidance for operators to comply with the fuel tank safety (FTS) requirements in the EAPAS/FTS rule.
