             For Requirement 5:  By 30 December 2005, except for engines with less than 4000 hours time-since-new (TSN) on 30 December 2005 when replacement must be carried out before reaching 4000 hours TSN.

             For TAY 611-8 and 651-54 series engines:

             For Requirement 1:  For engines with less than 4000 hours TSN the initial inspection must be carried out before reaching 4000 hours TSN after the effective date of this Directive.  For engines with more than 4000 hours TSN the initial inspection must be accomplished before further flight.

             For Requirement 2:  At intervals not to exceed 1000 hours TIS since last carrying out the inspection required by Requirement 1.

             For Requirement 3:  Within 1000 flight hours after the effective date of this Directive.

             For Requirement 4:  At intervals not to exceed 1000 TIS since last carrying out the inspection required by Requirement 3.

             For Requirement 5:  By 30 December 2005, except for engines with less than 4000 hours TSN on 30 December 2005 when replacement must be carried out before reaching 4000 hours TSN.
             This Amendment becomes effective on 4 August 2005.
Background:  In-service experience of the worldwide TAY 650 fleet has shown the possibility of fuel leakage from the engine low pressure fuel tube connected to the fuel flowmeter and high pressure pump.  Originally, AD/F100/57 was raised following a partial disconnect of the fuel tube causing a massive fuel leak which resulted in an in-flight double engine flame-out due to fuel starvation.  This Directive cancelled AD/F100/57 and raised a new Directive extending applicability to other RR TAY model/series engines.

             This amendment now includes inspection requirements for low pressure fuel tube P/N JR26955, reduces the repetitive inspection interval from 2000 to 1000 hours, and increases the period for replacement of the tubes from 30 June 2005 to 31 December 2005.

   Amendment 1 of this Directive included an additional fuel tube that is required to be replaced.  The compliance times did not change for both the inspection and replacement of the tubes.

   Amendment 1 of this Directive became effective 8 July 2004.

   The original issue of this Airworthiness Directive became effective on 16 July 2003.
