attachment and the upper and lower rear spar attachments.
                This Amendment becomes effective on 24 May 2013.
Background:     The original of this Directive was issued on 31 December 1981 because of service experience with corrosion and cracking of the wing spars, and outer wing attachment fittings and bolts.  It specified inspection in accordance with Beechcraft Service Instruction 0514-035 Rev 2.
                Amendment 1 became effective on 5 October 1989, and included inspection requirements for aircraft with the spar strap STC modification.
                Amendment 2 became effective on 9 August 1990 and incorporated the inspection method of the Beechcraft Structural Inspection and Repair Manual, which superseded SI 0514-035 Rev 2.
                Amendment 3 became effective on 10 August 2000, and was raised to reflect the amendment status of the Structural Inspection and Repair Manual, and to clarify the source and identity of the STC inspection document for modified aircraft.
                Subsequently, during a review of airframe ADs for the Beech heavy twins, it was realised that inspection of the wing attach nuts and bolts, which is a requirement of this AD, was duplicated by AD/BEECH 200/39 Amdt 4.  Amendment 4 consolidated the two ADs into one.  No additional requirements were introduced.
                Amendment 5 became effective on 20 November 2008 and was raised to reflect the amendment status of the Beechcraft Structural Inspection and Repair Manual.
                Amendment 6 is raised to correct the date of the requirement document and to allow the use of future revisions of the SIRM.
