SECTION IV
STRUCTURE
GENERAL
No structural repairs are recommended without contacting the manufacturer, however,
minor repairs such as patching the skin, etc., may be made in accordance with AC43-13-
XX for the airframe. It may be necessary to cut access holes to make skin repairs in some
areas of the aircraft.
Caution: Skin repairs must result in a surface which is as strong as, or stronger than, the
original skin. However, flexibility must be retained so that the surrounding areas will not
receive extra stress.
The rivets used on most parts are of the blind rivet type, reference #A4 (1/8” dia.) or A5
(5/32” dia.); to be set with the hand tool, reference #HP-A4-A5. Aircraft quality
aluminum “Cherry” rivets are an approved substitute. Standard MS20470 rivets may be
used where access is possible.
Repair Fiberglass parts with standard / typical Fiberglass type resin and woven Fiberglass
cloth. Using AC43-13-XX Chapter 3 is also acceptable.
When nylon locknuts are removed, the installation of new locknuts is highly
recommended.
Bolt torque valves are given in AC-43-13-1B Section 3
