REGULATORY TEXT:  
93-17-01 BEECH AIRCRAFT CORPORATION: Amendment 39-8671. Docket No. 93-CE- 23-AD.

Applicability: Models B90, C90, and C90A airplanes (serial numbers LJ-489 through LJ-1318), certificated in any category.

Compliance: Required within the next 150 hours time-in-service after the effective date of this AD, unless already accomplished.

To prevent failure of the leading edge fuel cell nipples caused by cracking and fuel leaks, which, if not detected and corrected, could result in an airplane fire, accomplish the following:

(a) Inspect the inboard nipple on the leading edge fuel cell for cracks or fuel leaks in accordance with Part I of the ACCOMPLISHMENT INSTRUCTIONS section of Beech Service Bulletin (SB) No. 2475, dated February 1993. If cracks or fuel leaks are found, prior to further flight, repair the fuel cells in accordance with procedures specified in the applicable maintenance manual.

(b) Replace the fuel interconnect tube assembly in accordance with Part II of the ACCOMPLISHMENT INSTRUCTIONS section of Beech SB No. 2475, dated February 1993.

(c) 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.

(d) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office, FAA, 1801 Airport Road, Mid-Continent Airport, Wichita, Kansas 67209. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita Aircraft Certification Office.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita Aircraft Certification Office.

(e) The inspection and replacement required by this AD shall be done in accordance with Beech Service Bulletin No. 2475, dated February 1993. 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 the Beech Aircraft Corporation, P.O. Box 85, Wichita, Kansas 67201-0085. Copies may be inspected at the FAA, Central Region, Office of the Assistant Chief Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri, or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
