Cruising comfortably at about 225mph (TAS@21,000ft), with a useful load of up to 2500 lbs, a turbine-powered Comp Air 8 will carry up to 6 adults (plus 2 children or lots of baggage) in comfort and style. Individual bucket seats are provided for six adults, with ample leg and head room. If desired, a bench seat can also be installed to provide seating for 2 children. The 31-1/2 ft. long Comp Air 8 is 2 feet longer than the popular Comp Air 7, and is designed to take full advantage of the Walter 601 turboprop engine’s outstanding load-carrying capability. With 237 sq. feet of wing area, the Comp Air 8 can easily accommodate a 4800 lb. gross weight (approximately 2000 to 2500 lbs. useful, depending on powerplant, options, and interior detailing). For real heavy haulers, optional 5200 lb. or 5600 lb. gross weight reinforcements are available. Tapered wings for faster cruise are included as a standard feature on the Comp Air 8. Because the CA8 is intended as a high performance, fast-flying load-carrying utility airplane, specially reinforced (carbon fiber) fuselage and tail group members are also included as standard features. Like all of Comp Air's  unique airplanes, optional floats are available for the Comp Air 8 Turbine.

The Comp Air 8 boasts a 46" wide cabi(up to 52" optional), sports 100% mass-balanced controls for high cruise speeds, has specially reinforced (carbon fiber) over-size tail surfaces for stability and control, includes an aerodynamically efficient and optically corrected windshield, and includes flush-mounted landing gear and flush-fit thermopane doors. Total fuel capacity is determined by the builder, who has the option of installing fuel tanks capable of carrying up to 180 gallons.

Owners of this impressive performance/utility airplane enjoy a useable range of 500 to 700 miles (with reserves), while carrying up to 6 adults at speeds well over 200 mph.
