a thrust reverser assembly that has the TRAS locks installed, reactivate the thrust reverser and functionally test in accordance with the appropriate approved maintenance data.
           Repair in accordance with the procedures specified in the appropriate approved maintenance data if any discrepancy is detected while carrying out the tests.

                               Terminating Action

           Accomplishment of the actions contained in Requirement 1(b) terminates the repetitive inspections required by Requirement 1(a) and 5 of this AD.

           Accomplishment of the installation specified in Boeing SB 747-78-2150, dated 20 March, 1997, terminates the requirement to comply with the installation contained in Requirement 1(b) of this AD.

           Note: FAA AD 2000-14-11 Amdt 39-11821 refers

Compliance: For Requirement 1(a) OR (b): Prior to the issue of a Certificate of Airworthiness.

           For Requirement 2: At intervals not exceeding 1,500 flight hours until accomplishment of Requirement 1(b).

           For Requirement 3: Within 3,000 flight hours after accomplishment of Requirement 1(b) modifications.

           For Requirement 4(a): At intervals not exceeding 3,000 flight hours. For Requirement 4(b) and (c): Prior to further flight.
           For Requirement 5: Prior to the issue of a Certificate of Airworthiness.

           For Requirement 6: At intervals not exceeding 18 months until accomplishment of Requirement 1(b).

           For Requirement 7(a) or (b): Prior to further flight.

           For Requirement 7(c): Within 10 days after thrust reverser deactivation in accordance with the provisions of Requirement 7(b).

This Airworthiness Directive becomes effective on 11 July 2002.

           Background: A study conducted by the manufacturer indicated that an uncommanded in- flight deployment of a thrust reverser could occur in climb at a high speed and engine power setting. Such a condition could result in a significant reduction in controllability of an aeroplane. The actions specified in this Directive are intended to ensure the integrity of the fail-safe features of the thrust reverser system by preventing possible failure modes, which could result in inadvertent deployment of a thrust reverser in- flight.
