To detect possible interference between the mid-cabin galley door and the emergency escape slide girt bar, accomplish the following: A. Within the next 300 flight hours time-in-service after the effective date of this AD or prior to January 1, 1979, whichever occurs first, unless accomplished within the last 1200 flight hours time-in-service, inspect the mid-cabin galley door for interference with the girt bar in accordance with Boeing Alert Service Bulletin 727-25-A247. B. Doors with interference are to be reworked prior to further passenger flight in accordance with Boeing Alert Service Bulletin 727-25-A247. C. Repeat the inspections, described in paragraph A, at intervals not to exceed 1,500 flight hours time-in-service or one (1) year from the last inspection, whichever comes first, unless the galley door is modified as described in Boeing Service Bulletin 727-25-A247, Revision 2, paragraph III, part II, or later FAA approved revisions, or in a manner approved by the Chief, Engineering and Manufacturing Branch, FAA Northwest Region. This modification is terminating action for this AD. D. Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Northwest Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator.
