93-11-10 CORPORATE JETS, LIMITED, (FORMERLY BRITISH AEROSPACE): Amendment 39-8602. Docket 93-NM-40-AD.

Applicability: Model BAe 125-1000A series airplanes, as listed in Corporate Jets, Limited, Alert Service Bulletin S.B. 71-A43, dated February 9, 1993; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To ensure the fireproof integrity of the engine fan duct material, which will reduce the hazards associated with an engine fire, accomplish the following:

(a) Within 7 days after the effective date of this AD, conduct a detailed visual inspection along the longitudinal seams of the outside surface of the outer fan duct on the right and left engines to detect fluid contamination or disbonding at the edges of the seams, in accordance with Corporate Jets, Limited, Alert Service Bulletin S.B. 71-A43, dated February 9, 1993.

(b) If no fluid contamination or disbonding is detected, accomplish paragraphs (b)(1) and (b)(2) of this AD.

(1) Thereafter repeat the visual inspection required by paragraph (a) of this AD at intervals not to exceed 14 days until the modification required by paragraph (b)(2) of this AD is accomplished.

(2) Within 300 hours time-in-service after the effective date of this AD, modify the longitudinal seams of the outside surface of the outer fan duct on the right and left engines, in accordance with Corporate Jets, Limited, Service Bulletin SB.71-43-3644A, dated February 8, 1993. Accomplishment of this modification constitutes terminating action for the repetitive inspections required by paragraph (b)(1) of this AD.

(c) If fluid contamination only is detected, accomplish paragraphs (c)(1) and (c)(2) of this AD.

(1) Repeat the detailed visual inspection required by paragraph (a) of this AD prior to the first flight of each day until the modification required by paragraph (c)(2) of this AD is accomplished.

(2) Within 50 hours time-in-service after the effective date of this AD, modify the longitudinal seams of the outside surface of the outer fan ducts on the right and left engines, in accordance with Corporate Jets, Limited, Service Bulletin SB.71-43-3644A, dated February 8, 1993. Accomplishment of this modification constitutes terminating action for the repetitive inspections required by paragraph (c)(1) of this AD.

(d) If disbonding is detected at the longitudinal seams, prior to further flight, modify the longitudinal seams of the outside surface of the outer fan duct on the right and left engines, in accordance with Corporate Jets, Limited, Service Bulletin SB.71-43-3644A, dated February 8, 1993.

(e) 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.

(f) 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.

(g) The inspection shall be done in accordance with Corporate Jets, Limited, Alert Service Bulletin S.B. 71-A43, dated February 9, 1993. The modification shall be done in accordance with Corporate Jets, Limited, Service Bulletin SB.71-43-3644A, dated February 8, 1993.
