The Beechcraft XT-36 (company designation Model 46, intended production designation T-36A) was an American twin-engine trainer-transport aircraft project of the early 1950s by the Beech Aircraft Company. The project was initiated by the United States Air Force on an expedited basis to address expected wartime aircrew training needs, but changing requirements led to delays, design difficulties, and spiraling development costs. The aircraft was ultimately deemed unnecessary and canceled before the prototypes flew.
