	The compliance times for Requirements 2 and 3 remain unchanged by this issue of the Directive.
	This Airworthiness Directive becomes effective on 5 July 2007.
Background:	The manufacturer required a mandatory inspection of the nose gear lower shock absorber for evidence of slippage at the intersection of the tube and fork assembly, and a dye check of the weld area on the fork assembly.Amendment 3 introduced a modification kit which, if fitted, removes the repetitive inspection requirement.Amendment 4 required the same inspection requirements by a different inspection method, but required incorporation of an improved nose landing gear fork kit anytime a crack is found; and added additional aircraft to applicability.Amendment 5 is issued to correct an error in Requirements 3, where Part III of the referenced Beech MSB should have been Part II. This error flowed from related FAA AD 2004-23-02.
