92-10-12 BEECH AIRCRAFT CORPORATION: Amendment 39-8246. Docket No. 91-CE-96-AD. Supersedes AD 91-18-11; Amendment 39-8014. Applicability: The following model and serial number airplanes, certificated in any category: Model Serial Numbers 200 and B200 BB-2 and BB-6 through BB-1404 200C and B200C BL-1 through BL-72 and BL-124 through BL-137 200CT and B200CT BN-1 through BN-4 200T and B200T BT-1 through BT-33 A100-1 (U-21J) BB-3, BB-4, and BB-5 A200 (C-12A) BC-1 through BC-75 A200 (C-12C) BD-1 through BD-30 A200C (UC-12B) BJ-1 through BJ-66 A200CT (C-12D) BP-1, BP-22, and BP-24 through BP-51 A200CT (FWC-12D) BP-7 through BP-11 A200CT (RC-12D) GR-1 through GR-13 A200CT (C-12F) BP-52 through BP-71 A200CT (RC-12G) FC-1, FC-2, and FC-3 A200CT (RC-12H) GR-14 through GR-19 B200C (C-12F) BL-73 through BL-112 and BL-118 through BL-123 B200C (UC-12F) BU-1 through BU-10 B200C (RC-12F) BU-11 and BU-12 B200C (UC-12M) FC-1, FC-2, and FC-3 B200C (RC-12M) BV-11 and BV-12 Compliance: Required within the next 50 hours time-in-service after the effective date of this AD, unless already accomplished (superseded AD 91-18-11). To prevent separation of the aft cowling doors, which could result in occupant injury if decompression or structural damage occurs, accomplish the following: (a) Inspect and modify the aft engine cowling doors of both engine nacelles in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Beech Mandatory Service Bulletin (SB) No. 2416, Revision I, dated December 1991. (b) If the aft engine cowling doors of both nacelles have been inspected and modified in accordance with the original issue of Beech SB No. 2416, dated July 1991, (as required by superseded AD 91-18-11), then no further action is required by this AD. NOTE 1: The configuration of certain early model airplanes made compliance with the original issue of Beech SB No. 2416 impossible as required by superseded AD 91-18-11. Service (SVR) 025 was approved as an alternative method of compliance for portions of superseded AD 91-18-11 on some of the affected early model airplanes. (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 should be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita Aircraft Certification Office. NOTE 2: 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 inspections and modifications required by this AD shall be done in accordance with Beech Mandatory Service Bulletin No. 2416, Revision I, dated December 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 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, 1100 L Street, NW; Room 8401, Washington, DC. (f) This amendment (39-8246) supersedes AD 91-18-11, Amendment 39-8014. (g) This amendment (39-8246) becomes effective on June 12, 1992.
