(1)HIRF means High Intensity Radiated Fields.
(2)HIRF/Lightning tasks in this section (AMM TASK 05-51-19-210-801 p201) are for scheduled maintenance.
(3)The purpose of the HIRF/Lightning inspections is to inspect wire bundle connectors for problems.
(4)The purpose of the HIRF/Lightning tasks is not to look along the lengths of the wire bundles.
(a) If you notice damage along the length of a wire bundle, make a note of the damage and do the necessary repairs after you complete the HIRF/Lightning inspection tasks.
(5)The inspections are applicable to the critical and essential systems and LRUs
NOTE:The emphasis of the HIRF/Lightning inspections is in the areas outside of the pressure vessel and in the Main Equipment Center. These areas are where HIRF/Lightning protection for systems is most important. If HIRF/Lightning protection problems exist, these are the areas where HIRF/Lightning protection will most likely be compromised. There may be systems listed in the following list which may not be inspected in any of the HIRF/Lightning inspections. This is because such systems may not have wire bundle connectors outside of the pressure vessel or in the Main Equipment Center.
