Piper Shimmy Dampener Repair Kit

Restoring your shimmy damper effectiveness

One of the most neglected components on Piper aircraft is the shimmy damper. The shimmy damper aids nose wheel steering by reducing the shimmy of the nose wheel during takeoff and landing, and during high-speed taxiing. Even minor shimmying can lead to serious damage to the nose gear and engine mount and affect the airworthiness of the aircraft. The shimmy damper is a sealed unit that, until now, could not be serviced and required costly replacement.

The STC and accompanying servicing kit allows your existing MAECO shimmy damper to be modified and serviced, restoring the shimmy damper to like-new condition and enabling it to perform as originally designed! The servicing kit installs in less than an hour by any A&P mechanic. Once modified, if the shimmy damper ever needs servicing again, the owner can service it with hydraulic fluid.

Our Shimmy Damper STC Kit is for the MAECO Shimmy Damper only and is non-refundable. Please check your shimmy damper for proper operation before ordering as there are many issues, other than a dry/empty shimmy damper can cause a shimmy in the nose gear. Please see the Piper MAECO Inspection Guide to help you determine if you need the servicing kit before ordering.
