in Appendix 2, after the effective date of this Directive. This Directive has effect from 02 January 1997.
           Background:  In-flight failures have been reported overseas, involving injuries. Inspection and replacement of windows will preclude failure with resultant injury to crew members and passengers. Amendment 1 revised the Directive to clarify Applicability and update the FAA AD reference.

           Amendment 2 was issued in response to a new FAA AD which shortened the repetitive inspection interval as a consequence of several acrylic window failures that occurred prior to the previously required inspection interval.

           Amendment 3 introduces a life limit for single pane cockpit side windows and a post installation inspection.

           Amendment 2 of this Airworthiness Directive became effective on 1 December 1993. Amendment 1 of this Airworthiness Directive became effective on 15 June 1989.
           The original issue of this Airworthiness Directive became effective on 26 January 1989.

At the effective date.   Inspect at 150 hours TIS after the effective date of this AD   Reinspect at intervals not to exceed 1,000 hours TIS or 12 calendar months, whichever occurs first, provided no cracks are found. Use applicable condition column entry to determine compliance times if cracks are found.

If cracks are found where the sum total of all cracks is less than                                                            Accomplish one of the following:                                                                                                                                                                                Accomplish the corresponding repetitive action:
4.3 inches in combined length, but where a crack meets or exceeds                                                                                                                                                                                                                                                                              1.  Reinspect initially between 10 and 20 hours TIS after replacing the window to ensure that no damage has occurred after installation, and thereafter at intervals not to exceed 1000 hours TIS or 12 calendar months, whichever occurs first, provided no cracks are found. Use applicable "Condition" column entry to determine compliance times if cracks are found.or
0.30 inches as specified in the Crack Limitations section of the service information referenced in paragraph 4. of this AD.   1. Prior to further fight, replace the window with a new approved window in accordance with the applicable maintenance manual.                                                                                  - - - - - - - - - - - - - - - - - -

Repeat the inspection specified in paragraph 2. of the AD at intervals not to exceed 25 hours TIS or 30 calendar days, whichever occurs first, provided the sum total of all cracks does not exceed 4.3 inches in combined length. Use the "If cracks are found where the sum total of all cracks meets or exceeds 4.3 inches in combined length" conditions column for replacement and inspection times if the cracks found are at that level.
