48-44-02   CURTISS-WRIGHT  Applies to all C-46 Series aircraft. 

	Compliance required at original certification and at every 7,500 hours of operation thereafter, or at the approved airframe overhaul period for air carriers. 

	Check the center wing-to-fuselage attachment bolts, P/N AN 8-23A, AN 8-25A, and AN 8-31A, to determine that they are properly torqued. The proper torque value for these bolts is between 480 to 690 inch-pounds as per Curtiss-Wright Drawing No. 20-230-1000. 

	For access to the 30 percent spar fitting, a 1 1/2-inch diameter hole can be cut in the wing center section lower skin beneath the fitting, just forward of the beam, and far enough inboard so that the resultant opening will be completely covered upon reinstallation of the wing foot fairing. 

	This supersedes AD 47-51-06.
