Beechcraft D18s

Twin Piston

The Beechcraft Model 18, universally known as the Twin Beech, stands as one of aviation's most enduring designs, with a production run spanning from 1937 to 1970 that yielded over 9,000 airframes. Originally conceived as a six-to-eight-seat business transport, the type became a workhorse across military, airline, and corporate roles throughout the mid-20th century, serving as everything from a World War II navigator trainer (the AT-7 and AT-11 variants trained tens of thousands of Allied aircrew) to a rugged bush freighter in Alaska and Canada. Its distinctive art-deco lines, all-metal construction, and twin Pratt & Whitney R-985 radial engines made it both reliable and repairable in remote operations, qualities that kept many examples flying decades beyond their intended service life. The D18S variant (the most common postwar civil model) featured upgraded engines, increased gross weight to 9,900 pounds, and improved cabin appointments that made it a favorite among corporate flight departments and small regional carriers in the 1950s and 1960s. While the type's performance envelope is modest by modern standards (cruise around 160-180 knots, service ceiling near 20,000 feet), its sturdy construction and straightforward systems have earned it a devoted following among warbird collectors and vintage aircraft operators. Today the Twin Beech remains a prized classic, with several hundred still on civil registries worldwide, many meticulously restored and flown at airshows or operated by enthusiasts who appreciate its blend of 1930s elegance and practical utility.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
