Compliance required at each annual inspection.
(1) Inspect plywood butt plates for separation from wing spar ends. Remove only if loose and inspect spar end for rot which requires repair or replacement. Separation of spar laminations does not require replacement if the glue joints between spar webs and caps are sound. Glue new butt plates to spar ends working glue into any cracks between laminations.
(2) Cut a total of sixteen 1/2-inch diameter inspection holes in wing lower skin. These should be centered at the front edges of both spars at four approximately equally spaced sparwise stations in each outer panel. Use caution to avoid cutting the spars and ribs. Inspect spars for rot and separation of the plywood webs from the caps. Deteriorated parts should be scrapped or repaired. Dope fabric patches over holes.
(3) Provides 1/4-inch drain holes in lower skin with centers not more than 1/4 inch from front face of spars and from outer edge of each rib wherever holes are missing or have greater spacing. Clean out all dirt built up above edges of holes to insure complete drainage. Install seaplane grommets at all drain holes in areas splashed by water from landing wheels.
