ACTION: Final rule; request for comments. ––––––––––––––––––––––––––––––––––– SUMMARY: The FAA is revising Airworthiness Directive (AD) 2001-13-18, which applies to Raytheon Aircraft Corporation (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) airplanes. AD 2001-13-18 currently requires you to repetitively inspect the wing spar assembly for cracks and replace any wing spar assembly found cracked (unless the spar assembly has a crack indication in the filler strip where the direction of the crack is toward the outside edge of the filler strip). AD 2001-13-18 also requires you to report the results of the initial inspection and maintain the flight and operating restrictions required by AD 99-12-02 until the initial inspection is done. We approved alternative methods of compliance (AMOCs) to AD 2001-13-18. We have since determined that those AMOCs do not address all critical areas in the wing spar assemblies and should no longer be valid. We are issuing this revision to AD 2001-13-18 for the purpose of eliminating the AMOCs to AD 2001-13-18. The actions of this AD are intended to prevent wing spar failure caused by fatigue cracks in the wing spar assemblies and ensure the operational safety of the above- referenced airplanes. DATES: This AD becomes effective on March 15, 2004. On August 16, 2001 (66 FR 34802, July 2, 2001), the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation. We must receive any comments on this AD by April 26, 2004. ADDRESSES: Use one of the following to submit comments on this AD: • By mail: FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2000-CE-09-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. • By fax: (816) 329-3771. • By e-mail: 9-ACE-7-Docket@faa.gov. Comments sent electronically must contain ''Docket No. 2000-CE-09-AD'' in the subject line.
