A final rule published last Friday harmonizes FAR Part 36 light, propeller-driven airplane noise certification standards with international standards and provides uniform noise certification requirements for airplanes certified in the U.S. and Europe, according to the FAA. This amendment will also simplify airworthiness approvals for import and export purposes, it added.

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.

A group of airports, local governments and residents has requested that Congress order the complete phase-out of all Stage 1 and Stage 2 aircraft regardless of weight. Sen. Frank Lautenberg (D-N.J.) has submitted such legislation.

Business aircraft crews and passengers are generally aware of the danger of prolonged exposure to noise in terms of hearing loss. Now there is a growing body of evidence that prolonged exposure to a combination of high-intensity and low-frequency noise may pose far more serious health threats.

New designs for small business turboprop singles could be included in proposed changes to FAR Part 36 noise-certification rules. The more stringent levels are aimed primarily at reducing noise from newly designed primary training aircraft, but new turboprop singles certified under Part 23 would also be covered. The FAA said the more stringent requirements are intended to keep limits within the capability of current technology.

The FAA is reviewing an FAR Part 150 noise-compatibility proposal for Little Rock National Airport, Ark., and expects to approve or disapprove the plan no later than July 21. The agency has already approved noise-exposure maps required under Part 150. A public comment period ends March 23. For more information, contact the FAA’s Tim Tandy at (817) 222-5635.

Few sounds are louder than a jet aircraft at takeoff.

The decibel level of a climbing jet engine at full power can be higher (140 dB) than that of a chain saw (110 dB) or ambulance siren (120 dB), according to the National Institute for Occupational Safety and Health.

But relief may be a toggle away, if recent university research finds its way into aircraft cockpits.

The FAA is reviewing a proposed noise-compatibility program for Lincoln Airport, Neb., and is expected to issue its findings no later than June 4. The program is being submitted under the guidelines of FAR Part 150, and comments can be submitted until February 9. For more information, call the FAA at (816) 329-2645.

Imperial Transport, flying a Citation 501, and US Smokeless Tobacco Brands, operating two Challenger 601s, received the “Spirit of Noise Abatement” awards for last year for achieving the lowest average sound level for a single jet and a fleet operation, respectively, at Westchester County Airport (HPN), White Plains, N.Y.

Even though noise wasn’t a factor in the accident, February’s Challenger overrun at Teterboro has inevitably resurrected local residents’ complaints about aircraft noise. It doesn’t take much, as we all know, to reinvigorate the anti-noise folks.
