A. Inspections
(1) Zonal Inspection
(a) A collective term comprising selected general visual inspections and visual checks that is applied to each zone, defined by access area, to check system and power plant installations and structure for security and general condition.
(2) General Visual Inspection (GVI)
(a) 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.
(3) Detailed Visual Inspection (DVI)
(a) An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirrors, magnifying lenses, etc. may be necessary. Surface cleaning and elaborate access procedures may be required.
(4) Special Detailed Inspection (SDI)
(a) An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity. The examination is likely to make extensive use of specialized inspection techniques and/or equipment. Specialized cleaning and substantial access or disassembly procedures may be required.

B. Checks
(1) Operational Check
(a) An operational check is a task to determine that an item is fulfilling its intended purpose. This type of check does not require quantitative tolerances. This a failure finding task.
(2) Visual Check
(a) A visual check is an observation to determine that an item is fulfilling its intended purpose. This type of check does not require quantitative tolerances. This is a failure finding task.
(3) Functional Check
(a) A quantitative check to determine if one or more functions of an item performs within specified limits.
