75-05-05 GOODYEAR AEROSPACE CORPORATION: Amendment 39-2101. Applies to main wheel assemblies P/N's 5000757-1 and -2 typically used on, but their use is not limited to, McDonnell-Douglas DC-10-30 and DC-10-40 series aircraft. \n\n\tCompliance is required at the next tire change or wheel re-assembly after the effective date of this Airworthiness Directive, unless already accomplished, and thereafter at each tire change or wheel re-assembly or during replacement of any wheel half attaching bolts in a tire/wheel assembly. New wheels or spare wheel assemblies with previously magnetic-particle inspected bolts are exempt only from the initial inspection. \n\n\tTo prevent failures of the MS 21250-10060 bolts attaching the wheel halves, accomplish the following: \n\n\t(a)\tPerform magnetic-particle inspection for cracks of all wheel-half attaching bolts, paying particular attention to the radius under the bolt head and to the threads. Replace cracked bolts and those having stripped, crossed ordamaged threads. No reworking of wheel bolts is permitted. Defective bolts shall be scrapped. \n\n\tThis amendment becomes effective March 26, 1975.
