Mooney M20A — Specifications

This document is a service instruction for the Mooney M20 series aircraft, specifically addressing the inspection of the Dukes landing gear actuator's rubber coupling. It outlines the procedures for inspecting and replacing the coupling to prevent potential landing gear collapse due to deterioration. The instructions are applicable to various models including M20C, M20E, M20F, M20G, and M20J, providing detailed steps for mechanics to follow during maintenance. The document emphasizes the importance of regular inspections and compliance with maintenance schedules to ensure safe operation of the aircraft's landing gear system.

• Inspect the Dukes rubber coupling every 200 hours or within the next 100 hours if not previously done.
• Use part number B100-06 for replacement of the rubber coupling if deterioration is found.
• Ensure the aircraft is on jacks before performing the inspection to keep landing gear off the ground.
• Follow the specific sequence of disassembly and reassembly to avoid damage to the actuator components.
• Document compliance in the logbook after completing the inspection and maintenance.
