QTA - Carbon Graphite Engine Inlet Upgrade

Terminate corrosion and never look back

King Air
Backed by a Lifetime Structural Warranty
- Lifetime means Lifetime

Operators of QTA’s carbon graphite inner barrels sleep well at night knowing they are covered under a lifetime structural warranty.

QTA Carbon Graphite Composite Replacement Inlet Barrel

  • Will Never Corrode or Fail
  • Dependable, Permanent, Safe
  • Transferable Warranty Remains with the Aircraft Serial Number
  • Adds to aircraft value

Challenger owners will never be offered a lifetime warranty on a factory or third party ‘repair’ because…a corrosion ‘repair’ only delays the inevitable return of corrosion. That is guaranteed!

Quiet Technology Aerospace backs its Lifetime Warranty with substantial Product Liability Insurance formed and placed by Lloyds of London.

You’re covered.

The ONLY Permanent Solution
to inlet corrosion

- not a repair, a SOLUTION

Combating the expensive and time consuming problem of aluminum inner-barrel engine inlet cowl corrosion and acoustic screen degradation is a serious and uncontrollable recurring condition.

Corrosion has caused engine ingestion of corroded aluminum FOD during operation with major engine damage resulting.

Quotes Icon

“We first used a QTA Inlet Upgrade in 2016 on our Learjet model 60’s with great success. We were excited to learn QTA had developed and produced an engine inlet upgrade for our Challenger 300 aircraft which were experiencing repeated corrosion issues. The combination of eliminating corrosion worries, the Life Time warranty, and excellent build quality reduces risk and cost for our customers which is an excellent fit with our requirements as a major 135 Charter operation.”
