The Piper 66074‑000 Push‑Pull Control Assembly is a flexible cable style control used in Piper aircraft to link cockpit controls to mechanical systems such as throttle, mixture, propeller governor, carb heat, alternate air, or similar linkages. These assemblies are designed to transmit linear motion (push and pull) smoothly and reliably under engine vibration, temperature changes, and long routing paths, enabling precise control inputs from the pilot.

Push‑pull control assemblies typically feature:

Flexible inner cable with low friction liner for smooth action. 
Metal end fittings and swivel joints for proper alignment and reduced wear. 
Durable outer conduit to protect the cable and maintain responsiveness. 
These assemblies are critical in aircraft control systems where rigid rods cannot be used due to firewall, panel, or engine compartment routing constraints. Certified FAA‑PMA replacements from suppliers like Univair or McFarlane are often used where Piper OEM parts are obsolete or hard to source.
