47-51-07   CURTISS-WRIGHT  Applies to all C-46 Series aircraft. 

	Compliance required not later than March 1, 1948, and each 1,000 hours of operation thereafter. 

	Inspect the landing gear drag strut support structure inside nacelle to determine if landing gear drag strut No. 20-720-1018 attaching bolts at the 70 percent spar have loosened and if angle assembly 20-720-1024-1 and bulkhead assemblies 20-720-1021-1 and 20-720-1023-6 are loose. All defective parts, loose or sheared attachment rivets should be replaced and loose bolts tightened. 

	To accomplish the above, it is necessary to remove one outer panel or provide an access door in order to gain access to the interior of the center panel. 

	(Curtiss-Wright Service Information Letter No. 735 dated August 20, 1947, covers an acceptable wing panel door installation.)
