The Driggers D1-A is an American-built light high-wing single-seat sporting monoplane of the late 1920s. Design and developmentWillard 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 historyThe 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] Specifications{{Aircraft specs |ref=Aerofiles |prime units?=imp |genhide= |crew=1 |capacity= |length m= |length ft=17 |length in=8 |length note= |span m= |span ft=22 |span in=9 |span note= |upper span m= |upper span ft= |upper span in= |upper span note= |mid span m= |mid span ft= |mid span in= |mid span note= |lower span m= |lower span ft= |lower span in= |lower span note= |swept m= |swept ft= |swept in= |swept note= |dia m= |dia ft= |dia in= |dia note= |width m= |width ft= |width in= |width note= |height m= |height ft= |height in= |height note= |wing area sqm= |wing area sqft= |wing area note= |swept area sqm= |swept area sqft= |swept area note= |volume m3= |volume ft3= |volume note= |aspect ratio= |airfoil= |empty weight kg= |empty weight lb= |empty weight note= |gross weight kg= |gross weight lb= |gross weight note= |max takeoff weight kg= |max takeoff weight lb= |max takeoff weight note= |fuel capacity= |lift kg= |lift lb= |lift note= |more general=
