The airworthiness directive
71-25-06 BOEING: Amdt. 39-1357. Applies to Model 707/720 airplanes certified in all categories. Compliance required within the next 300 hours time in service after effective date of this AD, unless already accomplished. To assure that water will not accumulate forward of the station 360 bulkhead on all Boeing Model 707/720 airplanes, accomplish one of the following: (1) Inspect the airplane per Boeing Service Bulletin 3027, dated 23 November 1971, or later FAA approved revisions. If the station 360 bulkhead drains are blocked or do not exist modify the station 360 bulkhead, bulkhead blanket and floor mat as described in the above service bulletin to provide the required drains. (2) Perform an equivalent inspection and (if required as a result of the inspection finding) modification approved by the Chief, Aircraft Engineering Division, FAA, Western Region. This amendment becomes effective December 13, 1971.
