Comp Air Series for Sale — Buy or Sell Aerocomp Turboprop Homebuilt Aircraft
The Comp Air Series — produced by Aerocomp Inc. (formerly Comp Air Inc.) of Merritt Island, Florida — represents one of the most ambitious and capable lines of homebuilt aircraft ever offered to the amateur-built market. Designed to bring genuine turboprop performance to the Experimental/Amateur-Built category, Comp Air aircraft are large, high-performance machines capable of carrying multiple passengers at speeds and altitudes that rival small certificated turboprop transports. Whether powered by piston or turboprop powerplants, Comp Air Series aircraft offer a level of capability and utility that is unique in the homebuilt world. On Airplane Trade, completed Comp Air Series aircraft are listed for serious buyers who demand exceptional performance from their homebuilt investment.
About Aerocomp / Comp Air Inc.
Comp Air Inc. was founded in the 1990s with the goal of designing large, high-performance composite kit aircraft that could be powered by turboprop engines — a category essentially unavailable to homebuilders at the time. The company's founders recognized that Experimental/Amateur-Built regulations allowed builders to construct aircraft of virtually any size or performance level, limited only by materials, design, and the builder's skill. The result was the Comp Air line — a series of composite aircraft ranging from four-seat singles to eight-passenger turboprop transports, all built from fiberglass and foam composite materials using the company's detailed construction manuals and prefabricated kit components. The company later reorganized as Aerocomp Inc., continuing to support existing builders and develop new designs.
Key Models in the Comp Air Series
- Comp Air 4 — Four-seat high-performance piston or turboprop single; designed for speeds up to 200+ mph on piston power; ideal entry point into the Comp Air lineup
- Comp Air 6 — Six-passenger turboprop-capable design; generous cabin, retractable gear, pressurization capability on some variants; outstanding utility aircraft
- Comp Air 7 — Seven-seat turboprop design; one of the most capable homebuilt utility aircraft available; used for backcountry operations, personal transport, and aerial photography
- Comp Air 8 — Eight-passenger turboprop; the largest Comp Air design; approaching light twin transport capability in a homebuilt framework
- Comp Air 10 — Ten-passenger configuration; one of the largest homebuilt designs ever certificated under E-AB rules
Powerplant Options
One of the defining characteristics of the Comp Air Series is its flexibility with powerplants. Builders have equipped Comp Air aircraft with a wide range of engines:
- Piston options — Lycoming IO-540, Continental IO-520/IO-550, and turbocharged variants for high-altitude performance
- Turboprop options — Walter M601 (Czech-manufactured turboprop, 700+ shp), Pratt & Whitney PT6A series (the gold standard of turboprop reliability), and the Allison 250 series adapted for fixed-wing use
- Jet options — Some ambitious builders have fitted small turbofan engines to Comp Air airframes for true jet performance in an experimental package
Turboprop-powered Comp Air aircraft offer cruise speeds of 250–300+ mph, service ceilings above 25,000 feet, and useful loads exceeding 2,000 lbs in larger configurations — numbers that would be at home in a certificated regional transport.
Construction Materials and Methods
Comp Air aircraft are built from fiberglass/foam composite sandwich construction, producing strong, lightweight structures that are resistant to corrosion and can be fabricated in a home workshop with basic tools and materials. The composite construction allows complex aerodynamic shapes that would be prohibitively expensive in metal construction, and the resulting surfaces are smooth and aerodynamically efficient. Builders work from detailed plans and prefabricated fiberglass shells, skins, and bulkheads supplied by the manufacturer.
Buying a Comp Air Series Aircraft: Key Considerations
- Airworthiness certification — Verify the E-AB airworthiness certificate and associated operating limitations document
- Turbine engine records — Turboprop engines have specific overhaul, inspection, and hot section requirements; verify all records are complete and current
- Composite structure inspection — Engage an A&P or composite specialist to inspect for delamination, impact damage, and moisture intrusion in the fiberglass structure
- Avionics suite — Comp Air aircraft are often equipped with sophisticated glass cockpit avionics; verify calibration, database currency, and proper installation
- Pressurization system — If equipped, pressurization system must be inspected for seal integrity and controller function
