ACTION:

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.
