Cozy Mark IV

These figures describe a typical build. Each aircraft of this design was built by its owner, and the one you are looking at may differ.

The Cozy Mark IV is Nat Puffer's four-seat development of the Long-EZ idea: a plans-built composite canard pusher with a 28 ft main wing, side-by-side front seats, two seats behind and a 180 hp Lycoming O-360, with a manually retracting nosewheel. The design's support site gives 2,050 lb gross, 1,050 lb empty and 220 mph maximum; the maker publishes no 75 %-power cruise or range figure.

It does a Bonanza's trip on an O-360's fuel, and the price for that is the canard's peculiarities and the plans-built reality. There is no conventional stall but there is a long, flat, nose-high approach at 80 knots or more, a pusher propeller that is vulnerable to everything the nosewheel throws, and a narrow centre-of-gravity range that makes loading a discipline; transition training with a canard pilot is expected by insurers. Every Cozy was laid up by hand by its builder, and foam-and-glass quality, the engine chosen, the empty weight achieved and any deviations from the plans (there are many, and the support site tracks them) matter more than the type figures; read the aircraft's own weight-and-balance and builder log. Owner maintenance and an A&P condition inspection apply. No current asking price was found.

  6. Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
