The Beechcraft Model 17 Staggerwing is an American biplane with an atypical negative wing stagger (the lower wing is farther forward than the upper wing). It first flew in 1932. Development At the height of the Great Depression, aircraft executive Walter H. Beech and airplane designer Ted A. Wells joined forces to collaborate on a project to produce a large, powerful, and fast cabin biplane built specifically for the business executive. The Beechcraft Model 17, popularly known as the "Staggerwing", was first flown on November 4, 1932. During its heyday, it was used as an executive aircraft, much as the private jet is now, and its primary competition were the Waco Custom Cabin and Waco Standard Cabin series of biplanes. The Model 17's unusual negative stagger wing configuration (the upper wing staggered behind the lower) and unique shape maximized pilot visibility and was intended to reduce interference drag between the wings (although it was later found to have negligible effect). The fabric-covered fuselage was faired with wood formers and stringers over a welded, steel tube frame. Construction was complex and took many man-hours to complete. The Staggerwing's retractable conventional landing gear, uncommon at that time, combined with careful streamlining, light weight, and a powerful radial engine, helped it perform well. In the mid-1930s, Beech undertook a major redesign of the aircraft, to create the Model D17 Staggerwing. The D17 featured a lengthened fuselage that improved the aircraft's handling characteristics by increasing control leverage, and the ailerons were relocated to the upper wings, eliminating interference with the flaps. Braking was improved with a foot-operated brake linked to the rudder pedals. Between April 1936 through May 1940 there were six Model 17 fatal accidents involving midair breakups that were attributed to weather conditions and structural failures, later determined to be caused by flutter of the ailerons and wings. The CAA Bureau of Safety Regulation initially issued an edict to restrict maximum airspeed and instrument flight, which was later replaced by a safety bulletin requiring lead balance weights to be added to the ailerons and flaps, and plywood panels to the outboard portion of the wings to increase torsional stiffness of the wing tip section. Operational history Sales began slowly. The first Staggerwings' high price tag (between US$14,000 and $17,000, depending on engine size) scared off potential buyers in an already depressed civil aircraft market. Only 18 Model 17s were sold during 1933,
