REGULATORY TEXT:  
77-03-02 R2 BOEING: Amendment 39-2826 as amended by Amendment 39-2852 is further amended by Amendment 39-4572. Applies to Boeing Model 727 Series airplanes certificated in all categories that have engine forward fuel feed hose assemblies which have accumulated 5 years or more or 12,000 hours or more time in service whichever occurs first. Compliance required as indicated.
To prevent rupture of the engine fuel feed hose assemblies, accomplish the following:
A. Within the next 60 days, unless already accomplished within the past six months, inspect and replace as required with a like part or an equivalent hose assembly approved by the Manager, Seattle Aircraft Certification Branch, FAA, Northwest Mountain Region, the No. 1 and No. 2 and No. 3 engine forward fuel feed hose assemblies in accordance with Boeing S.B. 727-28-51, Figure 3, pages 26 and 27, Steps 1, 2, 3, and 4 issued 11/12/76, or later FAA approved revision.
B. Within 3,000 hours time in service, install hose clamps on Engine No. 1 and Engine No. 3 forward fuel feed hose assemblies in accordance with Boeing Service Bulletin 727-28-51, Figure 4, pages 28 and 29, steps 1, 2, and 4 issued November 12, 1976, or later FAA approved revision.
C. Annually reinspect all hose assemblies not replaced per paragraph A above or at an interval that is compatible with the airlines' inspection schedules and approved by the assigned FAA Principal Maintenance Inspector with prior approval of the Manager, Seattle Aircraft Certification Branch, FAA Northwest Mountain Region.
D. If all hose assemblies are replaced per paragraph A., above, with corrosion resistant steel (CRES) braided hoses, the repetitive inspections required by paragraph C., above, may be discontinued as the installation of CRES braided hoses is considered terminating action for this AD.
The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).
All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to the Boeing Commercial Airplane Company, P.O. Box 3707, Seattle, Washington 98124. These documents may also be examined at FAA, Northwest Mountain Region, 9010 East Marginal Way South, Seattle, Washington.
