Piper Main Landing Gear Axle

• Can this part be used on aircraft with the PA-32R-301T designation?

  Yes. PA-32R-301T (the turbocharged Saratoga SP) is listed on the FAA-PMA supplement as an eligible aircraft for MC67184-000.

• Does installing MC67184-000 require special tooling?

  Yes, the installation and match drilling requires special tooling, capabilities, and treatments. The complete installation procedure is detailed in the Instructions for Continued Airworthiness (ICA) under the MC67184-000 documents tab.

• Is the McFarlane axle eligible for use on the PA-34-200T (turbocharged Seneca)?

  Yes. Both the PA-34-200 and PA-34-200T are listed as eligible aircraft for MC67184-000.

• What hardware is used to secure the axle to the strut?

  The axle is secured with an AN4-31A bolt, NAS1149F0432P washer, and MS21042-4 nut.

• What OEM part number does MC67184-000 replace?

  MC67184-000 directly replaces Piper P/N 67184-000. This axle is a sub-component of the Piper axle assembly P/N 67183-000, which is itself a sub-component of strut assemblies P/N 67307-004 and P/N 67037-006.

• What should I look for when inspecting the axle?

  Signs that the axle may need replacement include visible cracks or separation from the strut, a wheel that is tilted or not perpendicular to the gear leg, and surface discoloration, rust streaks, or hairline cracks. If any of these conditions are present, remove the axle for magnetic particle inspection.

• Why can't I just order the axle from Piper?

  Piper does not sell P/N 67184-000 as a standalone part. The only path through the OEM is to purchase the complete main landing gear strut assembly, which includes numerous components beyond the axle and represents a significant unnecessary expense when the axle alone is the problem. MC67184-000 is designed specifically to solve this.
