Corrosion Relief For Bombardier Challenger 300/350 Operators

The FAA has awarded an STC to Quiet Technology Aerospace (QTA) for its fifth airframe specific carbon fiber engine inlet replacement barrel. This STC offers a terminating solution to the plaguing issue of engine inlet cowl inner barrel corrosion impacting operators of the Challenger 300/350. The QTA STC is applicable to the global fleet of 659 aircraft.

Combating an expensive and time consuming problem of aluminum inner-barrel engine inlet corrosion and acoustic screen degradation on the Challenger 300/350 engines’ inlet cowls, QTA now offers a lighter weight state-of-the-art Carbon Graphite Composite Barrel that terminates the issue; and comes with a lifetime warranty that remains with the aircraft’s serial number. When installed, the inlets’ appearance is unchanged from the original.

QTA can provide a complete set of inner barrel upgrades to customers’ inlets in 15 days on the Challenger series, greatly reducing operator downtime compared to alternative corrosion repairs.

Additionally, QTA has a low cost inlet “loaner and exchange program” that keeps aircraft free from extended AOG conditions. QTA’s carbon graphite composite inner barrel comes with a lifetime warranty, assigned to the aircraft’s serial number for transferability.

The Challenger 300/350 solution is QTA’s fifth approved STC in their carbon fiber engine inlet solution programs. Other inner barrel corrosion affected airframes benefitting from QTA’s state-of-the-art engineering and carbon fiber manufacturing are the Lear 60, Gulfstream G200, Hawker 1000 and Falcon 2000EX/LX. QTA is now working on the design and certification of a further three aircraft types which suffer from the same inlet cowl corrosion issues.

Since the carbon fiber inner barrel replacement program began in 2015, operators of affected aircraft have shown enthusiastic support of QTA’s technology and the manufacturing quality of their product. QTA has installed 58 carbon fiber inlet barrels on 41 aircraft around the globe. Operators are both relieved from the corrosion problem that has plagued their engines’ inlets and impressed with the quality and reasonably priced QTA solution.

"With our fifth STC approval finalized for the Challenger 300/350 series, QTA now has a permanent and terminating corrosion fix for over 2,500 aircraft around the world," said Barry Fine, CEO of Quiet Technology Aerospace. "That represents a very large amount of time and money saved to operators that have been continuously troubled by expensive and time consuming inner barrel corrosion issues on their factory supplied engine Inlet Cowls. Our carbon fiber inlet program insures QTA customers a very simple and quick experience when upgrading…that is most of all, cost efficient and final.”
