Quiet Technology Aerospace (QTA) has been awarded FAA STC for its permanent solution to the plaguing problem of thrust reverser corrosion for the family of aircraft powered by the HTF7000 engine. The QTA corrosion solution is the market’s only permanent way to eliminate corrosion. It is not a repair.

The STC approves installation of the QTA upgrade on super mid-size jets, including: the Bombardier Challenger 300/350/3500; the Gulfstream G280; the Embraer Legacy 450/500 and Praetor 500/600. The Textron Longitude 700 will be added later.

There is a significant and recurring corrosion problem with thrust reverser doors and aft body assemblies on the thrust reversers installed on the family of aircraft utilising the Honeywell HTF7000 engine. Until now, an operator’s only remedy was to replace a TR door with factory new and, if the side beams are out of limit, a new aft body assembly, both at tremendous cost. Quiet Technology Aerospace expects its thrust reverser permanent solution that eliminates corrosion to be available imminently to global operators.

QTA has engineered a permanent solution that is unique in re-manufacturing the original doors, a one-piece forging in 7075, replacing the aluminium in the corroded area with a new titanium aft section. The aft body side beams are protected by a new titanium skin. QTA’s terminating solution maintains the same inner mould line and exit area as a new original TR.

The TR door and aft body permanent solution comes with a lifetime structural warranty that automatically transfers with the aircraft regardless of future sales of the airframe. Details of the introductory programme cost and replacement times are available from QTA representatives at EBACE Booth i51. QTA has received FAA certification for all the existing TR hardware and is able to supply the marketplace with hardware independent of TR upgrades. All QTA hardware will come with 8130-3 approval from QTA’s DMIR.

Barry Fine, CEO of Quiet Technology Aerospace, says: “It is just fantastic to now be able to provide operators with this solution. QTA has been engineering as hard and as smart as ever to bring to market our permanent corrosion solutions that make operating safer and far less expensive than the typical corrosion ‘repair’ that merely replaces corroded parts with factory new ones that are guaranteed to fail again. We look forward to seeing everyone again in Geneva and Las Vegas and proudly presenting our products.”
