The Turner T-40B is basically the same as the T-40A, but with tricycle landing gear and other improvements. Development of the prototype began in 1966 and the first flight was made in 1969. Originally an 85-hp engine was used, but it was replaced by a 125-hp Lycoming in order to improve high altitude performance. Other refinements on the basic T-40A frame are: a bubble canopy, hydraulically operated double-slotted flaps, and a fixed leading-edge droop.
