Footnotes 

This listing is for reference only.  For specific application information, or if there is any doubt about an application, refer to the aircraft equipment list or contact the engine manufacturer.

The application should be verified by type certificate data, as many engine models may use more than one P/N servo in different airframe installations.

Representative image only, actual item features may vary.
