Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required."

             2. If any discrepancy is found during the Requirement 1 inspection, repair or replace any damaged wires or worn components; install protective sleeving over the wire bundles and relocate the wire bundle to provide adequate clearance in accordance with Figure 1 of the Accomplishment Instructions of either ASB 767- 24A0139 or ASB 767-24A0140 as applicable.
