| Comments | NEW ARRIVAL! Factory Built, Beautifully Equipped Speedster! |
AirplanesUSA proudly presents one of the fastest normally aspirated fixed-gear airplanes in the world: the Columbia 300. Laminar-flow wing, composite structure. Powered by the 310-horsepower Continental IO-550, it's a true speed demon — nearly 200-knot cruise, and outruns a Cirrus SR22 by about 10 knots. Descended from a line of kit-built speedsters, this factory built certified normal category aircraft is rare on the ramp and turns heads. It has room comfortably for four. This comfy cockpit is 46-inches wide, has generous headroom, dual gullwing doors, and airy visibility. The design features no drag-inducing rivets or overlapping seams, with a finish smooth as silk. Custom laminar-flow wing and all-composite fiber build with a honeycomb fiberglass sandwich construction is complimented by 98 gallons usable fuel — six and a half hours at a high-speed cruise — a true cross-country machine.
This is a factory-built aircraft by Lancair - Not an Experimental Aircraft.
Updated panel — a true IFR platform. With the GTN 650Xi and the Aspen, it flies coupled WAAS approaches elegantly on autopilot - turns onto course, tracks final approach courses, altitude capture, the whole works.
Very well maintained: all ADs and optional SBs in compliance. Full logbooks in immaculate shape.
Export and Worldwide Delivery Available.
All Trades Considered.
