compliance with the equivalent requirements of this AD.

   Note 1:  Refer to FAA AD 2009-02-03 Amdt 39-15793 dated 13 January 2009, which supersedes FAA AD 2008-08-14.

   Note 2:  A special flight permit may be issued to reposition aircraft for compliance with Requirement 1 following a specified check of the servo plug by the pilot in command. No special flight permit can be issued for compliance with other requirements of this AD.

Compliance:  For Requirement 1:

                  (a) before further flight after 23 February 2009, unless previously accomplished; and

                  (b) until the P/N 365533 gasket is replaced with a P/N 2577258 gasket, repeat the inspection at the earlier of the following:

                     (i) every engine oil change;

                     (ii) every 50 flight hours.

             For Requirement 2 - before further flight.

             For Requirement 3 - by 31 December 2009.

             For Requirement 4 - after 23 February 2009.
             The effective date of this AD is 18 October 2013.
Background:  Servo plug gaskets, P/N 365533, are identified as being made of either a paper or fibre material, impregnated with synthetic rubber. They are relatively flexible and have a rough surface.

             Servo plug gaskets, P/N 2577258, are identified as being made of metal with a coating of synthetic rubber. They are relatively rigid and have a smooth surface.

             The FAA received 18 reports of fuel injection servo plugs, P/N 383493, that had loosened or completely backed out of the threaded plug hole on the regulator cover of the fuel injection servo.

             AD/FSM/31, which became effective on 14 March 2008, was intended to prevent a lean running engine, which could result in a substantial loss of engine power and subsequent loss of control of the aeroplane.

             AD/FSM/31 Amdt 1, which became effective on 9 May 2008, included an alternative means of compliance and terminating action as detailed in Precision Airmotive Service Bulletin PRS-107. The service bulletin provided for different inspection intervals and also a terminating action to the repeat inspection intervals.

             AD/FSM/31 Amdt 2, which became effective on 23 February 2009, made changes to the applicability section to clarify Teledyne Continental engine models and to include Bendix RSA-5 and RSA-10 servos. Replacement and fitment requirements associated with gasket P/N 365533 were also added.

   This AD, AD/FSM/31 Amdt 3, makes an editorial correction to the associated FAA AD references and other editorial changes. There is no technical change to the requirements and no change to the compliance from the previous amendment. Compliance with the previous amendment of this AD constitutes compliance with this amendment.
