Airworthiness Standards; Rain and Hail Ingestion Standards

This document proposes changes to the water and hail ingestion standards for aircraft turbine engines. This proposal addresses engine power-loss and instability phenomena attributed to operation in extreme rain or hail that are not adequately addressed by current requirements. This proposal also harmonizes these standards with rain and hail ingestion standards being amended by the Joint Aviation Authorities (JAA). The proposed changes, if adopted, would establish one set of common requirements, thereby reducing the regulatory hardship on the United States and worldwide aviation industry, by eliminating the need for manufactures to comply with different sets of standards when seeking type certification from the Federal Aviation Administration (FAA) and JAA.
