Description
Detailed Description Great airplane. Hurts to have to sell it. Will get you where you're going at 170 KTS TAS at 12000 feet on 11 GPH fuel burn. 72 usable gallons of fuel can give you 7 hours of endurance at economy cruise. Service ceiling with the turbo is 24,000 ft will get you above a lot of the weather but its sweet spot for performance is 10000 to 16000 ft. Turbocharger and 4 place fixed Oxygen system will let you climb high. Precise Flight speed brakes will help you get down without shock cooling your engine. Read below for details on avionics and check out that new paint and interior!! Annual completed May 31 2026 This is a fantastic airplane. I get compliments on it wherever I go. Yes, it is at TBO, but it runs great and I think smart buyers would prefer to select their own shop when the overhaul is needed. Great IFR platform especially with the Garmin GFC 500 Autopilot. Coupled approaches on GPS and NAV. Annual completed May 31. Altimeter and Transponder check due 03/2027 All Logbooks, as far as I know it's always been hangered.
