Policy for Repair and Alteration of Rotating Turbine Engine Life Limited Parts

摘要

The Federal Aviation Administration (FAA) announces the availability of proposed policy for the repair and alteration of rotating turbine engine-life limited parts (RTE-LLPs). This proposed policy establishes that the FAA will treat all repairs and alterations of RTE-LLPs as major repairs and major alterations. We are also proposing that all RTE-LLP repair and alteration data must include a methodology to assess the life of the repaired or altered part and the continued operational safety of the repaired product. This proposed policy provides guidance for: (1) Technical substantiation for repair or alteration of RTE-LLPs; and (2) Aircraft Certification Offices (ACOs) and Designated Engineering Representatives to evaluate and approve repair and alteration data.
