Stage 3 Helicopter Noise Certification Standards
This rulemaking proposes to adopt more stringent noise certification standards for helicopters that are certificated in the United States (U.S.). This rule would apply to applications for a new helicopter type design and for a supplemental type certificate for those new type designs. A helicopter type certificated under this standard would be designated as a Stage 3 helicopter. This rule proposes to adopt the same noise certification standards for helicopters that exist in the standards of the International Civil Aviation Organization (ICAO). The proposal of these more stringent noise certification standards into U.S. regulations is consistent with the FAA's goal of harmonizing U.S. regulations with international standards.
