Requires inspection and replacement, as applicable, of the left- and right-hand cockpit side windows. Prompted by occurrences of premature cracks in the outer layer of windows with P/N NP-200402-7 or -8 caused by interference due to manufacturing tolerances. These cracks, if undetected, may subject the inner layer to unpredicted loads and may result in window failure and subsequent in-flight depressurization.
