REGULATORY TEXT:  
92-06-16 BOEING: Amendment 39-8196. Docket No. 91-NM-191-AD.

Applicability: Model 757 series airplanes, listed in Boeing Alert Service Bulletin 757- 53A0060, dated August 8, 1991, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To prevent side-of-body floor panels from breaking away from the floor beams during a 9g forward load event, accomplish the following:

(a) Within the next 24 months after the effective date of this AD, examine the identification placards of each side-of-body floor panel to determine the manufacturer and date of manufacture of the panel, as specified in Figure 1 of Boeing Alert Service Bulletin 757-53A0060, dated August 8, 1991.

(1) If the panel was manufactured by Hexcel before January 7, 1991: Prior to further flight, repair all one-piece inserts in the panel or replace the panel, in accordance with Boeing Alert Service Bulletin 757-53A0060, dated August 8, 1991.

(2) If the panel was manufactured by Hexcel panel on or after January 7, 1991, or if the panel was not manufactured by Hexcel: No further action is required.

(b) An alternative method of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, Transport Airplane Directorate.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Seattle ACO.

(c) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base where the requirements of this AD can be accomplished.

(d) The inspection shall be done in accordance with Boeing Alert Service Bulletin 757-53A0060, dated August 8, 1991. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies may be obtained from Boeing Commercial Airplane Group, P.O. Box 3707, Seattle, Washington 98124. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue SW., Renton, Washington; or at the Office of the Federal Register, 1100 L Street NW., Room 8401, Washington, DC.

(e) This amendment becomes effective on April 28, 1992.
