The Driggers D1-A is an American-built light high-wing single-seat sporting monoplane of the late 1920s.
Design and development
[edit]Willard A. Driggers of Washington, DC and Willow Grove, Pennsylvania designed and built the D1-A in 1929. It is a parasol high-wing monoplane with the aerofoil braced from the upper fuselage and lower fuselage. A fixed tailwheel undercarriage is fitted. The tailplane is set high on the rear fuselage and is braced. The rounded fin has a large rudder area. The 60 h.p. Lawrance L-4 engine is fitted within an elegant curved cowling with the cylinder heads protruding to allow air cooling. The D1-A has manufacturers number 1 and is registered N891H.[1] Driggers went on to design and build the two-seat Driggers D2-A in 1933.[2]
Operational history
[edit]The builder and owner flew the D1-A from 1929 until 1936, when it was damaged in a ground loop. It was named Sunshine Girl III. The aircraft was stored until 1968 when an Experimental Aircraft Association group rebuilt it for static exhibition.[3] It is currently displayed at the EAA museum at Oshkosh Wisconsin.[4]
