Quiet Aviation, LLC (QA) is a Central Florida based company that specializes in experimental aircraft, powerplant, design, research and manufacturing with facilities at Deland Municipal and Orlando-Apopka Airports. 

The founders of Quiet Aviation have been in aviation some 50 years from Helicopters to Aerospace.

Deland Airport DED and Orlando Apopka Airport X04

The visionaries of QA are Al Aden and Fred Clark.

Al Aden was an Aerospace and Flight Test engineer with McDonnell Douglas participating in the F4 Phantom, F15 Eagle, and their Space programs.  His specialty was Data Acquisition and Analysis.  He holds Commercial, SEII, and Advanced Ground Instructor ratings.

Fred Clark has owned and operated OHA since 1964 specializing in helicopter projects that are a growth from the Sikorsky line.  Notable programs include the Orlando 18 passenger airliner and the Helicamper.  Fred is a high time pilot with SE, ME, Type, and Rotary ratings.  In recent years he had a Curtis Robin and CabinAire fully restored.  His last classic was a scratch-built Travel Air 2000 from factory plans that is discussed under Programs.

We do stand behind our products and will assist you personally, by phone, email, or on site answering and solving application and installation problems. We are retired and can give you the time, so go ahead and get some help. 

Enjoy our experimental Quiet Technology "QT430" powerplant, a 430 hp Chevrolet Corvette LS3 V8 engine package including a 25-year proven gear box, full electronics with an 8" LCD color monitor and diagnostics, and a ground adjustable propeller to match your mission. LET'S REDUCE YOUR FUEL COSTS TO 35¢ ON THE $1!

We offer the Travel Air as a plans or kit built airplane from factory plans using either the GM V8 or the 9-cylinder AI-14 260 hp radial. You will find certification of the Cessna 172 with the QT430 engine in progress with the STC expectations this fall. ANd there are several very interesting products or projects in work that you will find on the "Programs" page.

Quiet Aviation is a spirited business sparked by a couple of retirees fostering ideas and ambitions that have grown over years.  Now you get the benefit of those years and the developments all in one source.

QA is staffed with a broad group of very talented and specialized individuals, devoted to aviation, that have created a dynamic business that is now to be recognized.
