The Cozy Mark IV is a 4-seat, single engine, homebuilt light aircraft designed by Nat Puffer, with parts and plans supplied by Aircraft Spruce & Specialty Co. The aircraft is built from plans using basic raw materials. It is not a kit aircraft, though many small parts are available prefabricated. The Cozy is similar in design and construction to the 2-seat Rutan Long-EZ, from which it is derived,[2][3] with approval from Burt Rutan.
The Cozy Mark IV utilizes foam and fiberglass sandwich construction, with foam suited to the usage, fiberglass oriented for the stresses, and epoxy to bond them together.[3]
Nat Puffer designed the aircraft as a high speed cross-country visual flight rules (VFR) aircraft, although many builders equip their planes with instrument flight rules (IFR) capabilities.[4]
