Hollywood, Florida-based Quiet Technology Aerospace (QTA; Booth I51) has obtained an FAA supplemental type certificate (STC) for its permanent solution to thrust reverser corrosion on Honeywell HTF7000 turbofans. According to QTA, the STC will enable a repair of the corrosion problem at a considerably reduced cost versus replacing entire units.

Affected Honeywell engines power several super-midsize jets: the Bombardier Challenger 300/350/3500, Gulfstream G280, Embraer Legacy 450/500 and Praetor 500/600, and Cessna Citation Longitude. The STC applies to all models apart from the Longitude, although this will be added later.
