Title: ●Water and Hail Ingestion Standards
Abstract: This action proposes changes to the water and hail ingestion standards for aircraft turbine engines. This proposal addresses an engine power-loss instability phenomena attributed to operation in extreme rain or hail that is not adequately addressed by current requirements. This proposal also harmonizes with requirements being drafted by the Joint Aviation Authorities (JAA). The proposed changes, if adopted, will establish one set of common requirements, thereby reducing the hardship on the United States and worldwide aviation industry, by eliminating the need for manufacturers to comply with different sets of standards when seeking validation from the FAA and JAA.
