REGULATORY TEXT:  
87-06-11 BOEING: Amendment 39-5576. Applies to Model 747 convertible and freighter series airplanes listed in Boeing Alert Service Bulletin 747-53A2273, dated July 29, 1986, certificated in any category.

To prevent inadvertent in-flight movement of main deck cargo on freighter or convertible airplanes, accomplish the following, unless already accomplished:

A. Within 10 landings after the effective date of this AD, or immediately after the replacement or reinstallation of the restraint hardware, unless the requirements of paragraph B., for removal of placards, decals, or stencils, are accomplished, install suitable placards, decals, or stencils at all restraints along both left and right buttock lines (BL) 98.2, 9.8, and 1.8, between body stations (BS) 980 and 1500, that state the following:

"This restraint is inoperative. Cargo must be tied down per FAA-approved procedures."

B. Placards, decals, or stencils installed in accordance with the provisions of paragraph A., above, may be removed at each location where a determination is made in accordance with Boeing Service Bulletin 747-53A2273, dated July 29, 1986, or later FAA- approved revisions, that the restraint lip overlap meets or exceeds the minimum value specified therein, or if terminating action defined in paragraph C., below, is accomplished.

C. Terminating action for this amendment consists of the inspection of the seat track alignment and, if necessary, modification of the floor beams between body station 980 and 1480 in accordance with Section III., Part II of the Boeing Service Bulletin 747-53A2273, dated July 29, 1986, or later FAA-approved revisions.

D. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety and which has the concurrence of an FAA Principal Maintenance Inspector, may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

E. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD.

All persons affected by this directive who have not already received the applicable service bulletin from the manufacturer may obtain copies upon request to the Boeing Commercial Airplane Company, P.O. Box 3707, Seattle, Washington 98124-2207. This information may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

This Amendment becomes effective April 13, 1987.
