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.
