                   2. If the plug is found loose during the inspection detailed in Requirement 1, the registered operator must take all of the actions mentioned in paragraphs (a) to (j).

                     (a) Carefully cut and remove the safety wire that spans between the servo plug and regulator cover only.

        (b) Remove the servo plug and gasket, P/N 365533, that is behind the plug. The gasket may be slightly stuck to the regulator cover.

        (c) Examine the threads on the servo plug and regulator cover for damage. Threads should be smooth and consistent, with no burrs or chips. The servo plug outer diameter threads should also measure within 0.7419-0.7500 inch (18.84-19.05 mm).

        (d) If the threads on either the servo plug or the regulator cover are damaged, or do not measure within the limits in Requirement 2(c) of this AD, the servo must not be installed and must be replaced before further flight.

        (e) Replace the gasket, P/N 365533, with a new improved gasket, P/N 2577258.

        (f) While the hex plug is removed, stamp or scribe the letter "G" onto the face of the hex plug in accordance with Precision Airmotive LLC Mandatory Service Bulletin No. PRS-107 Revision 4, dated 16 July 2008 (the MSB).

        (g) When reassembling, do not install any servo plug or regulator cover that is not eligible for installation.  Install a new gasket, P/N 2577258, onto the servo plug and reassemble the servo plug to the regulator cover.

        (h) Torque the servo plug to a new, higher torque of 90‑100 in-lbs, to maintain the proper clamp-up force between the plug and cover.

        (i) Safety wire the servo plug to the regulator cover screws using wire with between 0.015 and 0.025 inch diameter in accordance with the MSB.

        (j) Inspect all other safety wires on the servo. Replace any that are damaged.

      3. The mandatory terminating action for the repetitive inspections required for compliance with Requirement 1, is that the registered operator must replace all servo plug gaskets, P/N 365533, that are installed on servos affected by this AD, with gasket, P/N 2577258, in accordance with the actions mentioned paragraphs (a) to (j) of Requirement 2.

      4. A person must not install a gasket, P/N 365533, onto any fuel injection servo.
   Later revisions of the MSB, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance to FAA AD 2009‑02‑03 are considered acceptable for compliance with the equivalent requirements of this AD.
