result.
(2) Install web straps before lifting any load.
(3) When lifting a loaded M3 CROP using multipurpose provision rings located at front and rear
of M3 CROP, use a spreader bar if necessary to avoid damage to load.
c. Inspection of Installed Parts. Perform inspection with the item in its normally installed posi-
tion or condition, considering accessibility and visibility of the item being inspected. The purpose of the inspection
is to determine if the item is damaged or incomplete to the extent that it should be replaced/repaired.
(1) Inspect for loose, missing or damaged parts.
(2) Inspect parts for dents, holes, worn spots, scratches, marred finish, cracks, rust and corro-
sion.
(3) Look for loose or chipped paint, rust or gaps where parts are welded together. If a bad weld
is found, notify your supervisor.
