Aircraft model

AERONCA 0-58B

Everything here is true of every aircraft of the type, not of any one aircraft.

The O-58B is the Aeronca Grasshopper, later redesignated L-3B: a wartime liaison and artillery observation aircraft built on the prewar Tandem Trainer airframe with extensive greenhouse glazing behind the cabin for the observer. Thousands were built and surplus aircraft went onto the civil register after the war.

It is bought for the history and for the extraordinary visibility, and it is flown the way any 65 hp fabric taildragger is flown — slowly, locally, and on good days. The glazing is the distinguishing feature and also a maintenance item, because replacement panels are specialist items. Fabric is the dominant lifetime cost. Wartime airframes have military maintenance histories that need reading, and the conversion paperwork to civil standard category should be checked. Warbird-restored examples sell well above tidy flyable ones.

  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.
