Beech 18 (Turbo)

Twin Turboprop· 3 globally registered

The Beechcraft Model 18, affectionately known as the Twin Beech, stands as one of general aviation's most enduring success stories. First flown in 1937, this twin-engine workhorse remained in continuous production for an astonishing 32 years until 1970, with over 9,000 airframes built across dozens of variants. The B18T designation indicates a turbocharged variant, typically modified from earlier E18S or H18S models with aftermarket turbocharging systems that significantly improved high-altitude performance and hot-and-high operations compared to the naturally aspirated originals. While Beechcraft never factory-produced a B18T model per se, the designation became common shorthand for turbocharged conversions that extended the type's utility well into the jet age. The Twin Beech served virtually every aviation role imaginable: corporate transport, cargo hauler, air ambulance, aerial survey platform, flight trainer, and bush aircraft. Its rugged construction, reliable Pratt & Whitney R-985 radial engines (or Continental variants in later models), and excellent short-field performance made it a favorite in remote operations from Alaska to the Australian outback. The type's spacious cabin and relatively high cruise speed of 200-220 knots made it competitive with early turboprops for regional work through the 1970s. Though largely retired from commercial service today, the Twin Beech remains a sought-after warbird and vintage transport, with several hundred still flying worldwide.
