View source for Drilled Yoke for A/P Interrupt or PTT switch

From time to time, the question of how to drill a hole in the yoke to accommodate a PTT switch.

As it turns out, American Aviation did this for the Century Autopilot's interrupt switch.

Here is a copy of the factory drawing, 5804014C, showing how they did it for AA5s, through early AA5Bs. This drawing was made inactive dated 5 June 1975.
