Piston Pawn® (M18, M14 and M12)
Piston Pawn® (M18, M14 and M12)
For the convenience of drop in protection of the uppers while your plugs are out for maintenance or magneto checks.
For YOU, the maintainer, the “PISTON PAWN ® “ is designed to fit M18 (Lycoming, Continental), M14 eMag Adapter and M12 (Rotax) spark plug holes. Made for your convenience, the non-threaded, “drop in” pawn is used during standard practice maintenance to prevent debris from accidentally entering open ports and creating foreign object damage (FOD). Designed and distributed in the USA by Swearingen 3D works of Marion IOWA, the "PISTON PAWN ™" was tested by our A&P staff at C17, and now in use by the fleet. Made to order, they are now prepared just for you and your bird.
The non-threaded,“Drop in plug” is undersized relative to the hole threads.
