Development of Transport Category Airplane Electrical Wiring Interconnection Systems Instructions for Continued Airworthiness Using and Enhanced Zonal Analysis Procedure
Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS/FTS)” rule. That rule requires design approval holders (DAHs) and applicants to develop instructions for continued airworthiness (ICA) consisting of maintenance and inspection tasks, intervals, and procedures for the representative airplane’s electrical wiring interconnection systems (EWIS) for each affected type design. The DAH must also review any fuel tank system ICA it has developed in compliance with Special Federal Aviation Regulation No. 88 (SFAR 88) in order to ensure compatibility with the EWIS ICA, including minimizing redundant requirements. The DAH must then submit the EWIS ICA to the Federal Aviation Administration (FAA) oversight office for review and approval.
This AC provides guidance for developing maintenance and inspection instructions for EWIS using an enhanced zonal analysis procedure (EZAP). For the purposes of this AC, the term “maintenance” encompasses both “maintenance” and “preventive maintenance,” as those terms are defined in Title 14, Code of Federal Regulations (14 CFR) 1.1. For airplane models whose maintenance programs already include a zonal inspection program, the logic described here provides guidance on improving those programs. For airplanes without a zonal inspection program, use of this logic will produce zonal inspections for wiring that can be added to the existing maintenance program. This AC contains information that can be used by operators to improve EWIS maintenance practices. It stresses the importance of inspecting EWIS and
promotes a philosophy of “protect and clean as you go” when performing maintenance, repair, or alterations on an airplane.
|120-93||ANM-100||Damage Tolerance Inspections for Repairs and Alterations This advisory circular (AC) provides guidance material for Type Certificate (TC) Holders, Supplemental Type Certificate (STC) Holders, and operators to comply with requirements in the Aging Airplane Safety Act to ensure the airworthiness of aging airplane parts and components. The Aging Airplane Safety Rule that supports the Act specifies incorporating damage tolerance-based inspections into an operator’s continuous airworthiness maintenance program. These inspections will help ensure the integrity of fatigue critical structure on transport category airplanes operated in air transportation. This guidance will provide persons who have developed repairs and alterations with a means to develop damage tolerance data to be used to determine damage tolerance inspections for repairs and alterations that affect fatigue critical structure. This AC will give guidance on developing compliance documents, schedules and plans that will assist in developing and incorporating damage tolerance inspections into maintenance programs of certain transport category airplanes with respect to repairs and alterations.||11-20-2007|
|120-73||ANM-100||Damage Tolerance Assessment of Repairs to Pressurized Fuselages Provides guidance to operators of certain transport category airplanes operated under 14 CFR Parts 91, 121, 125, and 129.

The means of compliance described is intended to provide guidance to supplement the engineering and operational judgment that must form the basis of any compliance findings relative to repair assessments for pressurized fuselages.||12-14-2000|

Statistical Analysis Considerations for Comparative Test and Analysis Based Compliance Findings for Turbine Engine and Auxiliary Power Unit Replacement, Redesign and Repaired Parts
a. This advisory circular (AC) describes acceptable statistical methods, but not the only methods, to help develop substantiating data for comparative test and analysis compliance findings. The findings support the Federal Aviation Administration (FAA) approval of turbine engine and auxiliary power unit (APU) replacement, redesign and repaired parts produced under:
(1) Parts manufacturer approval (PMA),
(2) Type Certificate (TC),
(3) Supplemental Type Certificate (STC), or
(4) Repair or alteration.
b. The AC describes statistical principles that can be used to help determine adequate sample sizes for a comparative showing of equivalency of parts from different design or manufacturing processes. The guidance in this AC is acceptable for determining sample sizes and/or populations of specimens. The resulting data may be used to support a showing of compliance to the airworthiness requirements of Title 14 of the Code of Federal Regulations (14 CFR) 21.303, 14 CFR part 33, 14 CFR part 43 and Technical Standard Order (TSO) C77.

Oxidation, Hot Corrosion, Thermal Fatigue, and Erosion Characteristics Testing to Support 14 CFR, Part 33, § 33.15, Compliancefor Turbine Engines
This advisory circular (AC) describes an acceptable method, but not the only method, to support certain comparative assessment compliance findings to Title 14 of the Code of Federal Regulations (14 CFR) part 33, § 33.15, Materials, for turbine engine projects. Comparative assessment of certain data is often necessary to show the required functional and durability equivalencies between engine combustor and turbine section parts from different design or manufacturing processes, e.g., parts manufacturer approvals (PMA) versus type design parts. These equivalencies relate to oxidation, hot corrosion, and thermal fatigue and erosion characteristics in the engine environment. This data is necessary to support overall FAA design approval of turbine engine and auxiliary power unit (APU) parts approved under PMA, type certificate (TC) design change, supplemental type certificate (STC), or repair or alteration authority.
