​
The Durand Mk V was a two-seat sports biplane aircraft developed in the United States in the 1970s and marketed for home building. The design was distinctive due to a large negative stagger on the wings, but was otherwise conventional. The single-bay wings were braced with I-struts, and while both upper and lower wings were equipped with full-span flaps, lateral control was by spoilers on the lower wing rather than ailerons. Flight testing revealed that the aircraft was impossible to stall. The pilot and single passenger sat side by side beneath an expansive canopy, and the undercarriage was of fixed, tricycle type.

Durand sold 75 sets of plans by 1987, and by that time, at least five aircraft (including the prototype) were known to be flying.
