3-8. Welding on Aircraft. Welding will not be
accomplished on operational aircraft until the following
precautions have been observed:
Place a fire extinguisher in immediate area and
observe all fire precautions.
Isolate area to be welded from all parts or
members which might be injured by contact with
Insulate area to be welded using fire retardent
materials to prevent heat distortion or damage to
