Flying a civilian Skymaster without prop spinner

[Learjetter]

Karl,
Sounds like you’ve got a conundrum.

A look at the A6CE type certificate lists prop spinners along with governors and blades. The FAA defines “airworthy” as “conforming to the type certificate AND in a condition for safe operation.”

You may not be able to qualify for a ferry permit if the FSDO determines the type certificate language means spinners must be installed.

Alternatively, they may be swayed by the Mil-version of the type cert as an example of “safe condition to operate.”

Good luck—let us know how it goes!
