OVERVIEW
Visible deformation of or damage to any aircraft skin warrants a complete
inspection of the underlying parts or structures. If all damaged parts are replaced in
accordance with the Kit Assembly Instructions KAI no consultation of the manufacturer
is necessary.
Small patch repairs to skins as outlined in AC 43.13 are allowed without consulting the
aircraft manufacturer if the total patch area does not exceed 60 square inches. Repair to
interior structural parts of the airframe or skin repairs (other than replacement of the
entire skin or patches to skins) of more than 60 square inches are not allowed without
consulting with the airplane manufacturer and receiving approval of the planned method
of repair. Note: Integral stringers formed on the edge of skins are considered interior
structure.
