QTA Adds To Inner Barrel Corrosion Solution STC
Quiet Technology Aerospace says this latest STC, its seventh, applies to Embraer Legacy 450/500 and Praetor 500/600 business jets.

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.
