Quiet Technology Aerospace (QTA) has received an STC for a solution to engine inlet cowl inner barrel corrosion on Embraer Legacy 450/500 and Praetor 500/600 business jets. The STC covers replacing the aluminum inner barrel on Honeywell HTF7500 engine inlets with a lighter-weight carbon-graphite composite barrel that the Hollywood, Florida-based company said terminates the root cause of the “plaguing” corrosion issue.

 


A lifetime warranty on the composite barrel will remain with the aircraft’s serial number and transfer to any future owner, QTA said. This is the seventh STC QTA has received for a solution to inner barrel corrosion found on Learjet 60, Gulfstream G200 and G280, Hawker 1000, Falcon 2000LX/EX, and Challenger 300/350 series airframes.

 


“With our seventh STC approval finalized for the Embraer EMB 545/550 series aircraft, QTA now has a permanent and terminating corrosion fix for more than 2,100 aircraft around the world,” said QTA chief executive Barry Fine. “That represents a large amount of time and money saved to operators that have been continuously troubled by expensive and time-consuming inner barrel corrosion on their original OEM inlet cowls, not to mention the already documented danger of engines ingesting corroded aluminum while operating."
