Compliance with the requirements of Requirement 4 of this Directive is terminating action for the tests/inspections specified in Requirement 1.

Note: FAA AD 94-16-03 Amdt 39-8993 refers and supersedes FAA AD 92-03-03.

For Requirement 2: At intervals not exceeding 3,000 flight hours since last test/inspection.

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

For Requirement 3 (c): Within 10 days after thrust reverser deactivation. For Requirement 3 (d) and (e): Prior to further flight.

This Airworthiness Directive becomes effective on 31 October 2002.

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
