STRUCTURES
Visually inspect all weldments and related components. It is important to inspect the fasteners that
connect the components.
WELDMENTS
To inspect weldments:
1. Visually inspect all weldments for abnormal wear, abrasion or deformation that could cause
interference between moving parts.
2. Inspect the welds on the structural components. The area to be inspected should be clean and
free of dirt and grease.
3. Look for visible cracks in the welds and at the weld to parent material joints. A bright light may
be used to provide adequate visibility of the inspection area.
4. Pay close attention to welds in areas where changes in cross section takes place near the at-
tachment points of highly loaded components.
FASTENERS
To inspect the fasteners:
1. Visually inspect all fasteners to see that none are missing or loose.
2. Inspect all of the bolts, nuts, rollpins, collars, and snap rings. They should all be present, tight, and
not damaged in any way.
UPPER CONTROL STATION
Inspect the platform and upper controls only if all functions operated properly from the lower controls.
