New Noise-Reduction System Receives FAA Approval

Aftermarket modification company Aviation Fleet Solutions tells Aero-News the company has teamed with Pratt & Whitney to develop and certify a new noise-reduction system, that reduces cumulative noise from the JT8D-200-powered MD-80 aircraft by as much as six decibels.

The new system, QuietEagle, is a Pratt & Whitney design that has been exclusively licensed to AFS for the MD-80.  It meets all the requirements of FAR Part 36 Stage 4 and ICAO Annex 16 Chapter 4 noise standards, which became effective January 1, 2006. The system has recently received certification by the FAA. First units will be ready to ship to airline customers in May 2006.

"This fairly simple modification will significantly extend the productive life of the MD-80 fleet, particularly in Europe where operators face expensive penalties for operating noisier aircraft," said Kevin Bartelson, president of Aviation Fleet Solutions.

"It is also a tremendous hedge against potential future penalties, restrictions and phase-outs" said Kimberley Sullivan, JT8D program manager with Pratt & Whitney.

The QuietEagle (shown above) includes an improved front fan case, a 16-lobe mixer, a muffler and a tabbed nozzle. The new technology hardware replaces older hardware components. Installation can be completed on-wing, in about 160 man-hours. With proper planning, Aviation Fleet Solutions expects that experienced mechanics will be able to install the kit within 24 hours.
