           Background: This amendment to the Directive includes numerous editorial changes that include changes to the structure of the requirements and compliance sections. These changes have no affect on the original technical requirements of this Directive. However, it should be noted that the MEL relief provisions have been modified to better amplify the requirements in this regard.

           The actions specified in this amendment, and the original Directive, are intended to prevent possible discrepancies in the thrust reverser system that can result in an inadvertent in- flight deployment.

           Previous amendments to this Directive were made to:

                 * include reference to "maintenance action" for compliance with Requirement 1;

                 * mandate the incorporation of thrust reverser synch-locks; and

                 * introduce repetitive tests of the synch-lock system

 AD/B767/63 Amdt 4 (continued)

           The repetitive function tests required after the thrust reverser additional locking system has been incorporated, as required by this Directive, is the subject of AD/B767/89 Amdt 1. This action separates the requirements for the thrust reverser in order to provide ease of maintenance control.

           The original issue of this Airworthiness Directive became effective 2 April 1992. Amendment 2 of this Airworthiness Directive became effective 8 December 1995. Amendment 3 of this Airworthiness Directive became effective 18 July 1996.
