REGULATORY TEXT:  
47-07-03 FAIRCHILD: (Was Service Note 4 of AD-724-2.) Applies to M-62 Series Aircraft.

Prior to original certification and at each periodic inspection thereafter, and as otherwise noted, make the following inspections:

(1) Inspect the wing center section bottom surface for cracks. This inspection should be made after each severe landing. Cracks extending into the spar flange area indicate cracked spar flanges and should be investigated very thoroughly.

(2) Inspect the butt ends of the spars to assure that the butt plates are in place and properly attached.

(3) Inspect the strap hinge fittings for looseness. Clearance between the spar webs and hinge plates is not critical as long as the plates are bolted tight to the bushings if the bushings protrude. If bushings are loose, replace.

(4) Inspect the plywood spar webs for checks or cracks. This inspection should always be made after any damage to the landing gear. Cracks other than those parallel to the face grain generally indicate serious damage to the spar web.

(5) Inspect the trailing edge of the wing center section and outer panel over flap area for deterioration due to accumulated moisture.

(6) Inspect the forward face of front spar and belly skin at engine cutout in wing center section for oil soaking and skin separation.

(These inspections and methods of repair are covered in greater detail in Fairchild Service Bulletin 47-62-1 dated January 24, 1947. Owners may obtain copies from Fairchild Personal Planes Division of Fairchild Engine and Airplane Corp., Hagerstown, Md.)
