The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Boeing 727 Series Aeroplanes
AD/B727/203  Mid-Cabin Galley Doorway Upper  7/2006
             and Lower Hinge Cutouts

Applicability:  Model 727, 727C, 727-100, and 727-100C aircraft.
Requirement:    Action in accordance with the technical requirements of FAA AD 2006-09-03 Amdt 39-14573.

                Note:  Boeing Alert Service Bulletin 727-53A0228 original issue, or later FAA approved revision, refers.

                6 July 2006.
                This Airworthiness Directive becomes effective on 6 July 2006.
Background:     The FAA received reports of skin and bear strap cracking at the upper and lower hinge cutout and along the upper fastener row of the stringer 14R lap splice, and cracking in the doorstop fitting adjacent to the upper hinge cutout.  There were also reports of cracking on aircraft previously modified in production.  Such fatigue cracking of the fuselage could result in reduced structural integrity and possible rapid decompression of the aircraft.
