           Accomplishment of Requirement 4 satisfies the inspections and test requirements in Requirements 1 & 2.

           Note: FAA AD 2000-01-05 Amendment 39-11502 refers which supersedes FAA AD 99-18-03 amendment 39-11269 (the FAA AD that caused the original AD/B747/214 to be raised).

Compliance: For Requirement 1: Unless previously accomplished, within 90 days from 4 October
2001.

                        For Requirement 2: At intervals not to exceed 18 months time in service until requirement 4 is accomplished.

           For Requirement 3: (a)  Prior to further flight.

                        (b) Prior to further flight.

           For Requirement 4: Within 36 months from 4 October 2001.

           For Requirement 6: At intervals not to exceed 3000 flight hours. For Requirement 7: (a)              Prior to further flight.

           This Amendment becomes effective on 11 July 2002.

           Background: The original and Amendment 1 issue of this Directive was raised to ensure the integrity of the fail safe features of the thrust reverser system were maintained by preventing possible failure modes which could result in inadvertent deployment of a thrust reverser during flight. Amendment 2 was issued to reflect the latest issue of Boeing SB 747-78-2156 but did not add aircraft or require more work on aircraft changed in accordance with the original issue of the service bulletin. This amendment has been issued to include minor editorial changes and to transfer Note 1 into a positive terminating action paragraph.

           The original issue of this Airworthiness Directive became effective on 2 December 1999.

           Amendment 1 of this Airworthiness Directive became effective on 13 July 2000. Amendment 2 of this Airworthiness Directive became effective on 4 Oct 2000.
