Wood props are generally the less expensive choice.

Wood props must be sent back to the factory for overhaul.

After a metal prop strike, the engine should be disassembled and inspected.

In the event of a prop strike, the wooden propeller will itself be destroyed but in most cases not damage the crankshaft.

While metal props accumulate invisible flaws from vibrations and flexing, wood props are not affected.

Wood props are lighter and result in an increase in payload.

While wood propellers are not certified for many airplanes, for those for which they are certified there are some advantages:

The "DA" indicates the blade design.Ĭhoosing between a fixed pitch wood or a fixed pitch metal airplane propeller For example in the blade model 90DA-2 the propeller will have an 88 inch diameter (90 inches minus 2 equals 88 inches). The propeller diameter is a result of the difference between the first two digits and the dash number at the end of the blade model number. In addition to the Propeller Model number there is a blade model number for all McCauley Propellers.

The C1100 series - Garrett engine propellers - five bladed The C1000 series - Pratt and Whitney Turbine Engine Propellers - five bladed The C700 series - Pratt Whitney Turbine Engine Propellers - either three or four bladed The C600 series - Garrett Turbine Engine propellers - either three or four bladed The C500 series - three-bladed constant speed feathering propellers The C400 series - three-bladed constant speed non-feathering propellers The C300 series - two-bladed constant speed feathering propellers The C200 series - two-bladed constant speed threadless non-feathering propellers A Propeller Technician may refer to a McCauley Propeller as a C66 (threaded) or a C203 (threadless) - names which in "propeller speak" accurately identifies a McCauley Constant Speed Propeller Model. If there are three digits following the "C" the propeller will be a threadless blade design and is current production. If there is only two digits following the “C" the propeller will be a threaded propeller and an obsolete design. The most important designator in a McCauley Constant Speed Propeller Model will be the two or three digits following the "C" at the end of the model number. (This first constant will be followed by a two digit number value between 31 and 37 which reflects a particular McCauley design.) McCauley Constant Speed propeller model numbers have two important constants - one at the beginning that designates the number of blades and one at the end that specifically identifies the propeller model.Ī numerical value at the beginning of the model number in either the first or second position (i.e. B2 or 2A) indicates the number of blades.
