REGULATORY TEXT:   78-24-05 R1 BOEING: Amendment 39-3355 as amended by Amendment 39-3871. Applies to Boeing Model 727 and 727-100 series passenger airplanes, and Model 727-51C airplanes operating in the passenger mode.

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.

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.

All persons affected by this directive who have not already received these documents from the manufacturer, may obtain copies upon request to Boeing Commercial Airplane Company, P.O.
