The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

The modification involves replacing the header panel assemblies of the number 3 left and right emergency exit doors (includes replacing the double hinged panels above the doors with new single panels), trimming the top portion of the door liner seal, and installing a new seal, retainer, and support angle. Accomplishment of the modification required by this paragraph terminates the requirements of AD 91-01-05, amendment 39-6850.
