Noise Certification Standards for Tiltrotors
This rulemaking would establish noise certification standards for issuing type and airworthiness certificates for a new civil, hybrid airplane-rotorcraft known as the tiltrotor. This rule proposes to adopt the same recommended guidelines for noise certification found in the International Civil Aviation Organization (ICAO) Annex 16, Volume 1, Chapter 13, Attachment F (Amendment 7) for tiltrotors certificated in the United States (U.S.). The ICAO recommended practices are already harmonized internationally, and the adoption as standards into our regulations would be consistent with the Federal Aviation Administration's (FAA) goal of harmonizing U.S. regulations with international standards. The proposed standards would apply to the issuance of the original type certificate, changes to the type certificate, and standard airworthiness certificates for tiltrotors.
