About the Beech 18

The Beechcraft Model 18, universally known as the Twin Beech, stands as one of aviation's most enduring designs: a twin-engine piston workhorse that flew from 1937 through 1970 in continuous production, longer than any other American aircraft. Originally conceived as a six-to-nine-passenger business transport, the type became a military training staple during World War II (as the C-45 Expeditor and AT-11 Kansan) with over 4,500 built for the armed forces, then transitioned smoothly into postwar civilian roles ranging from corporate shuttle to cargo hauler to aerial survey platform. Its rugged all-metal construction, reliable Pratt & Whitney R-985 radial engines, and docile handling made it a favorite among bush operators, commuter airlines, and charter services across North America and beyond.

The Twin Beech's distinctive tapered fuselage, art-deco lines, and throaty radial rumble remain iconic at airshows and vintage fly-ins today. With a cruise speed around 175 knots, service ceiling near 20,000 feet, and range exceeding 1,200 nautical miles, the Model 18 offered genuine twin-engine capability in an era when most light twins were far less capable. Thousands were built across dozens of variants, from the early A18 through the Super 18 and pressurized conversions, and many remain airworthy eight decades later, testament to Beech's engineering.
