FAA/JAA Helicopter Noise Standards Harmonized

 - April 2, 2007, 10:31 AM

Manufacturers of newly designed helicopters will have to meet slightly revised U.S. noise standards, effective with applications for new designs or major design changes submitted after June 1. The FAA revised FAR Part 36 to harmonize helicopter noise standards with those of the JAA and ICAO. Helicopter manufacturers requested this action to minimize their costs for demonstrating compliance, as well as facilitating exports and international trade. “This final rule does not substantively alter the prescribed noise limits or change the relative stringency of the regulations, such as the relationship between the noise level limits and the measured noise level of a given helicopter,” the agency said. “The FAA has determined that the changes will not substantively alter the noise certification levels or the finding of compliance for helicopters currently certified under Part 36.”
