This number suffixed by the letter “T” indicates that the diameter has been obtained by telescoping the original blade model. Telescoped blades are eligible at the same rating and diameter limitations as cut-off blades. Blades of the basic model designation are of laminated mahogany and birch construction. A letter suffix added to the model designation denotes a change in material as follows: C-walnut and birch; B-birch; M-maple; MB-maple and birch.

The left hand version of an approved model propeller is eligible at the same rating and diameter limitations as listed for the right hand model. NOTE 6. Interchangeable Blades. A listing is given of those blades which are sufficiently similar to be considered aerodynamically interchangeable in the same diameter without a flight test. P-216A may replace P-206 or P-206A. Provided that they are of the same balance category and of the same diameter, a model P-206 may be assembled in the same hub with a model P-206A, or P-216A blade, or a model P- 206A may be assembled with a model P-216A blade.
