FAA OKs QTA's Composite Inlet for Gulfstream G350/450
Quiet Technology Aerospace (QTA) carbon fiber engine inlet replacement barrel has been STC’d for the Gulfstream G350 and G450.

A carbon-fiber engine inlet replacement barrel from Quiet Technology Aerospace (QTA) has been STC’d for the Gulfstream G350 and G450, marking the eighth airframe to be FAA STC approved for its inlet corrosion solution. This STC offers the only terminating action currently available for aluminum engine inlet cowl inner barrel corrosion on the G350/450’s Rolls-Royce Tay 611-8C turbofans, the company said.

QTA’s solution replaces the aluminum inner barrel with a composite barrel that not only eliminates the root cause of the corrosion issue but also results in a weight savings of 30 pounds per inlet. It comes with a lifetime warranty that remains with the aircraft’s serial number and transfers to any future owner.
