Cessna M337B
Everything here is true of every aircraft of the type, not of any one aircraft.
M337B is the civil designation carried by surplus Cessna O-2A Skymasters, the military forward-air-control version built 1967-70 with structural beef-ups, hard points and extra windows on a 337B-era airframe. Two 210 hp Continental IO-360s give 125 knots at 10,000 ft and about 920 nm; the military empty weight was 2,848 lb against a 5,400 lb wartime takeoff weight.
Aviation Consumer calls them possibly the least expensive warbirds available, and that is the trade: an airframe that was flown hard, often stored for decades, with a military fit of wiring, armour and window glazing that no civil parts catalogue covers, all on top of the ordinary 337 themes of rear-engine cooling, the hydraulic gear power pack and a spar inspection history. The civil gross weight and usable fuel depend on how each aircraft was conformed when it left the military, so read the aircraft's own paperwork rather than this row for weight-and-balance. A rating earned in a Skymaster carries a centreline-thrust limitation. No current listing was found, so the price is blank.

- 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.
