QTA’s experience in the application of advanced composites for noise attenuation and structures now combating the expensive and time-consuming problem of engine Inlet Cowl aluminum inner-barrel corrosion and acoustic screen degradation, QTA provides a lighter weight state-of-the-art Carbon Graphite Composite Inner Barrel that terminates the issue; and comes with a lifetime warranty that remains with the aircraft’s serial number. This is not a repair which will fail again, potentially causing engine damage, but a permanent solution to the issue. QTA also provides repair and is working on a permanent solution for the HTF 7000 Thrust Reversers which also suffer from corrosion.
