   Note 1:  For the purposes of this Directive, a general visual inspection 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 ensure visual access to all surfaces in the inspection area.  This level of inspection is made under normal available lighting conditions such as daylight, hangar
