3. ACCOMPLISHMENT INSTRUCTIONS

NOTE: 1) For the purpose of this Service Bulletin, a General Visual Inspection (GVI) is: “A

visual examination of an interior or exterior area, installation or assembly to

detect obvious damage, failure or irregularity. This level of inspection is made

from within touching distance, unless otherwise specified. A mirror may be

necessary to enhance visual access to all exposed surfaces in the inspection

area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight or drop-light and may require

removal or opening of access panels or doors. Stands, ladders or platforms may

be required to gain proximity to the area being checked.”

2) Obey all of the WARNINGS and CAUTIONS included in the referenced manuals

and procedures.
