Overview

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, which 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.

Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: What exactly is included this Piper Shimmy Damper servicing kit?

Servicing kit includes: FAA authorization to modify present shimmy dampener, drill with stop special servicing screw which retains hydraulic fluid, instructions

Q: We have a Piper Shimmy Damper P/N# PS-50152-6 (from a PA32R-00 aircraft). Does this kit apply?

The kit works with MAECO shimmy dampeners only. It will not work with the PS series.

Q: Does Piper shimmy dampener service kit support the pa-34-200t, 1977?

Yes, it does.

Q: Will this kit work on a PA-22 dampener?

No, the PA22 is not listed on the application guide.

Q: Does this kit only provide for an oil filler opening? Or does it allow for O-ring changes? In the latter case, the cylinder would need to be cut open and later closed again after installing the new O-rings.

The STC allows you to drill a hole for refilling the hydraulic fluid. There are no o-rings or seals inside the MAECO dampener, so nothing has to be replaced inside. Once the hole is drilled and the dampener is filled with fluid we supply a screw with a seal to close up the hole and then it is serviceable from there on out.
