QTA can take a thrust reverser door that has corrosion beyond the OEM limits and remanufacture the door to an upgraded standard. The same is true for side beams.
The Permanent Solution replaces the aluminum in the corroded area with new titanium parts and the side beams are protected by a new titanium cap. This eliminates the need replace a thrust reverser door and side beams with factory new.
QTA’s Permanent Solution has been under FAA review for an STC. According to the QTA, STC approval appears imminent.
Specifically, the STC QTA is working to receive is for four airframe types:
- Challenger 300/350
- Gulfstream G280
- Embraer Legacy 450/500; Embraer Praetor 500/600
- Textron Longitude
When completed, the QTA thrust reverser door corrosion Permanent Solution provides the owner with a lifetime structural warranty, which is assigned to the aircraft’s serial number and transferrable throughout the life of the aircraft.
The new QTA titanium parts are hot formed in CP70 titanium.
Attachment of the new titanium part to the existing structure is conventional using Hi-Loks. The internal contour and exit area of the thrust reversers is kept exactly as the original so there is no impact on engine performance.
While QTA does expect STC approval prior to the end of 2022, it can offer operators who cannot wait, an FAA-approved interim and immediate "life extension" repair to corroded thrust reverser doors. The life extension applies even if thrust reverser doors or side beams are beyond economical repair (BER). Owners choosing the life extension repair will earn significant credit toward the Permanent Solution in the future if they choose.
