The Brunner-Winkle Bird was a three-seat taxi and joy-riding aircraft produced in the US from 1928 to 1931.
Design and operation
The Model A version was powered by the ubiquitous Curtiss OX-5, and featured a welded steel-tube truss fuselage with metal and fabric skinning. The wings, constructed of Spruce and plywood were also covered with metal and fabric skinning. The Model A had a reasonable performance for an OX-5 powered aircraft. The Model A's ease of handling led to its entry into the 1929 Guggenheim Safety Airplane contest, where it was awarded the highest ratings for a standard production aircraft.{{cite web |title=The Brunner Winkle Bird at the Cradle of Aviation Museum |url=http://www.cradleofaviation.org/history/history/aircraft/brunner_winkle_bird.html |first=Talmage |last=John |website=www.cradleofaviation.org |accessdate=21 September 2018}}
The Model A was awarded Group 2 approval no 2-33 in January 1929 for the first nine aircraft serial no. 1000 to 1008. Aircraft serial no. 1009 upwards were manufactured under Air Transport Certificate no. 101.{{cite book |last1=Juptner |first1=Joseph J. |title=U.S. civil aircraft series:Vol.2 |date=1 May 1993 |publisher=TAB AERO |isbn=978-0830643677 |page= 9 |url=https://archive.org/details/uscivilaircraft0002jupt |url-access=registration }}
The Model B followed on from the initial Bird design and was fitted with the uncowled Kinner radial engine. Production aircraft were designated BK.
