REGULATORY TEXT:  
80-02-02 R2 BOEING: Amendment 39-3660 as amended by Amendment 39-3863 is further amended by Amendment 39-3970. Applies to Model 737 series airplanes certificated in all categories which have an operative Boeing designed auxiliary body fuel system installed. Compliance required within 600 flight hours from the effective date of this AD unless this initial inspection and test has been previously accomplished within the past 300 flight hours. To prevent failure of the fuel system and unwanted fuel transfer to the auxiliary body fuel tanks, accomplish the following:

A. Inspect and test the auxiliary body fuel tank installation as required and as outlined in Boeing Service Bulletin 737-28A1032 or later FAA approved revisions. If the shrouds are found defective, replace with a serviceable Boeing part or deactivate the system prior to further flight.

B. Repeat the required inspections and tests every 1500 flight hours after the initial inspection unless the system has been deactivated. If shrouds are found defective, replace with a serviceable Boeing part, or deactivate the system prior to further flight.

The recurring inspection interval may be adjusted upon request of the operator. The FAA Maintenance Inspector, subject to prior approval by the Chief, Engineering and Manufacturing Branch, Northwest Region, may adjust the repetitive inspection interval specified in this AD if the request contains substantiating data to justify the increase.

C. Prior to reactivating a previously deactivated auxiliary body fuel system, whether deactivated voluntarily or due to defects found in the auxiliary tank fuel system through inspections and tests accomplished in paragraphs A. and B. above, the auxiliary body fuel system must be repaired as required and shown to meet the requirements of paragraph A. and must be reinspected on a recurring basis per paragraph B.

D. Installation of the following Boeing final design part numbered refuel and vent line shrouds for the corresponding original and or interim design Boeing Part Number refuel and vent line shrouds will relieve the operator from compliance with the inspection and test requirements outlined in Paragraphs A, B and C above. This constitutes terminating action for the AD.
