1966 Beechcraft B55 BaronMulti-Engine Piston Aircraft

This 1966 Beechcraft B55 Baron (N50780) is a distinctive warbird-configured twin with a notable military heritage, having been one of only 65 Barons originally purchased by the U.S. Army Aviation School. The aircraft underwent a Cole Mill President 600 conversion, boosting its combined engine output to 600hp through its twin Continental IO520E2BN engines (300hp each), with 1,570 hours SMOH on the left engine and 1,186 SMOH on the right—both below their 2,000-hour TBO. The airframe shows 10,280 total hours and has been stored in a heated Denver hangar since its last annual inspection in 2017.

Equipped with Hartzell props (both at 2 hours since new), the Baron retains its military-inspired restoration, complete with de-ice boots, alcohol-prop systems, built-in oxygen, and ADS-B compliance. The avionics suite includes Collins VHF/UHF radios, ADF, full co-pilot instruments, and a Davtron voltage standby inverter. While the exterior and interior are rated 6/10, the aircraft comes with complete military and civilian logs. Its 136-gallon fuel capacity and warbird pedigree make it a candidate for airshow or specialty operations, though prospective buyers should account for its storage period and pending annual inspection.
