REGULATORY TEXT:  
92-21-01 BRITISH AEROSPACE: Amendment 39-8381. Docket No. 92-NM-51-AD.
Applicability: Model BAe 146-100A, -200A, and -300A series airplanes; as listed in British Aerospace BAe 146 Inspection Service Bulletin SB 28-18, dated March 12, 1991; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent fuel seepage into a passenger compartment, in the event of a wing center section fuel tank leak, which could result in fire or explosion, accomplish the following:

(a) Within 6 months after the effective date of this AD, perform a visual inspection of the polymer coating applied to frames 26 and 29 in the center section of the wing, to detect voids and excessive thickness of the polymer coating that will not permit a visual inspection of the underlying structure, in accordance with British Aerospace BAe 146 Inspection Service Bulletin SB 28-18, dated March 12, 1991.

(b) If no voids are found and if the polymer coating is of sufficient thickness so as to allow a visual inspection of underlying structure, no further action is necessary.

(c) If any voids are found, or if the polymer coating is found to be excessively thick: Within 12 months after the completion of the inspection required by paragraph (a) of this AD, perform a visual inspection of the polymer coating applied to the wing center section fuel tank and to frames 26 and 29, to detect additional voids or excessive thickness, in accordance with British Aerospace BAe 146 Inspection Service Bulletin SB 28-18, dated March 12, 1991.

(1) Prior to further flight, repair all voids detected, in accordance with paragraph 2.B.(3) of the Service Bulletin.

(2) Prior to further flight, repair all excessively thick polymer coating areas detected, in a manner approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

(d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113.

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

(f) The inspections shall be done in accordance with British Aerospace BAe 146 Inspection Service Bulletin SB 28-18, dated March 12, 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 British Aerospace, PLC, Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, DC 20041-0414. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

(g) This amendment becomes effective on November 24, 1992.
