The Only Solution for Terminating Engine Inlet Cowl Barrel Corrosion – Program’s 7th STC Approval valid for:
EMB545-LEGACY 450/PRAETOR 500
EMB550-LEGACY 500/PRAETOR 600
Quiet Technology Aerospace (QTA) has received STC (Supplemental Type Certificate) # ST04464AT approval for its seventh airframe specific carbon fiber engine inlet replacement barrel. This STC offers a terminating solution for Embraer Legacy 450/500 and Praetor 500/600 operators over the plaguing issue of engine Inlet Cowl inner barrel corrosion on the Honeywell HTF7500 engine inlets. This represents QTA’s third inner barrel STC for aircraft powered by the HTF 7000 series engine.
Combating an expensive and time-consuming problem of aluminum inner-barrel corrosion and acoustic screen degradation on the 130 Embraer EMB545/550 series aircraft in service, QTA replaces the aluminum based inner barrel with a lighter weight state-of-the-art Carbon Graphite Composite Barrel which terminates the root cause of the corrosion issue; and comes with a lifetime warranty that remains with the aircraft’s serial number and transfers to any future owner. It is the only permanent solution available today.
When installed, the inlets appearance is better than originally manufactured. This is not a repair to the original aluminum inlet which will certainly fail again, potentially causing engine damage in flight. It is a permanent and terminating solution to the corrosion issue.
The latest QTA program STC is valid for Embraer Legacy 450/500 series aircraft as well as to the next gen Embraer Praetor 500/600 aircraft. The Embraer aircraft part number replaced is WBE7160E101-045.
The Embraer Legacy solution is QTA’s seventh approved STC in their carbon fiber engine inlet solution program that began in 2015. Other inner barrel corrosion affected airframes benefitting from QTA’s state of the art engineering and carbon fiber manufacturing are the Lear 60, Gulfstream G200 & G280, Hawker 1000, Falcon 2000LX/EX and Challenger 300/350 series.
In its 35 year history, exactly zero QTA’s inlet upgrades have failed on aircraft operating over 20 years. The company’s first inlet upgrade was for the Douglas DC-8 in 1986.
Additionally, QTA offers a low-cost inlet “exchange program” that keeps aircraft free from extended AOG conditions. QTA can provide either Exchange inlets or upgrade a complete set of Inlet Cowls in three weeks, greatly reducing operator downtime compared to alternative corrosion repairs.
As mentioned, QTA’s carbon graphite composite inner barrel comes with a lifetime warranty, assigned to the aircraft’s serial number that automatically transfers to any future owner. The QTA upgraded inlet cowls have life time Product Liability Insurance placed via Lloyds of London. The combined Product Warranty and Liability Insurance provides owner confidence for total coverage over the life of the aircraft.
Since the carbon fiber inner barrel replacement program began in 2015, operators of affected aircraft have shown enthusiastic support of QTA’s technology and the manufacturing quality of their product. QTA has installed 125+ carbon fiber inlet barrels on 70 aircraft around the globe. Operators are both relieved from the corrosion problem that has plagued their engines inlets and impressed with the quality and reasonably priced QTA solution.
Barry Fine, CEO of Quiet Technology Aerospace; “With our seventh STC approval finalized for the Embraer EMB 545/550 series aircraft, QTA now has a permanent and terminating corrosion fix for over 2100 aircraft around the world. That represents a large amount of time and money saved to operators that have been continuously troubled by expensive and time consuming inner barrel corrosion on their original OEM Inlet Cowls, not to mention the already documented danger of engines ingesting corroded aluminum while operating. The carbon fiber inlet program insures QTA customers a safe, simple and quick experience when upgrading that is most of all, cost efficient and final. Ours is the industry’s only permanent solution.”
Fine continues, “Of important note to operators considering QTA’s permanent solution versus a ‘repair’ that is 100% guaranteed to fail again…our warranty program is for the life of the aircraft and is transferable to future owners. The warranty stays with the aircraft, period. There are companies promoting a repair to the corrosion problem that comes with a ‘lifetime warranty’…but be aware of the fine print. There are a myriad of conditions and operator maintenance practices that must be followed to the letter in order for the warranty to remain in effect and not denied. A repair to the corrosion problem is only a temporary fix and it will fail again.”
QTA’s other STCs for Inlet Upgrades cover the following aircraft types:
- Bombardier Challenger 300 and 350
- Bombardier Learjet 60 and 60XR
- Dassault Falcon Jet 2000LX-EX
- Gulfstream G200 & G280
- Hawker 1000
Quiet Technology Aerospace will be exhibiting at the 2019 NBAA Convention in Las Vegas, Nevada / Booth #C8340.
