Action
Notice of proposed rulemaking (NPRM).
Summary
This document proposes to require that the maintenance or inspection programs for all airplanes operated under part 121 of Title 14, Code of Federal Regulations, all U.S.-registered multiengine airplanes operated in common carriage by foreign air carriers or foreign persons under 14 CFR part 129, and all multiengine airplanes used in scheduled operations under 14 CFR part 135 include FAA-approved corrosion prevention and control programs. Such programs are needed because existing maintenance and inspection programs may not provide comprehensive, systematic measures to prevent and control corrosion. These proposals form a part of the FAA's response to legislation emanating from the Aging Aircraft Safety Act of 1991. These actions are intended to control the detrimental effects of corrosion and the resulting airplane structural material loss.
