Last week Cirrus World Headquarters in Duluth, MN, hosted the Aviation Rulemaking Committee (ARC) for FAR 23 - flight into known icing. This was the fourth of five planned meetings of this committee in the past year. Forming of ARC's is common now to ensure that all the expertise in the industry and FAA is involved in creating new rules or guidance. This FAR 23 icing ARC follows the release of a notice of proposed rulemaking (NPRM) for FAR 25 - flight into known icing - earlier this year. The purpose of this ARC is to help formulate the icing regulations and advisory circulars for Part 23 airplanes and Part 33 engines. This ARC is composed of representatives from the FAA, airframe and engine manufacturers, and industry icing experts. Thirteen representatives were in attendance for this meeting.
Together committee members review the current regulations and advisory materials and proposed Part 25 regulations and advisory materials to determine what is appropriate for Part 23 airplanes. Following that review, the ARC will submit rule change recommendations and provide suggested wording for advisory materials to the FAA. The FAA is then expected to take these recommendations and formulate a NPRM for Part 23 airplanes in the next year or so.
