These areas are usually the result of prevailing installation procedures and are of no significance. A wing bolt should not be rejected because of cadmium plating deterioration.\n\n(c) the increase of the compliance time for Requirement 3 in the AD from 15 years to 20 years after the first installation of a new zero-time wing bolt.\n\n> Note All other requirements and compliance times stated in the AD remain unchanged.\n\n(2) In this section:\n\n> relevant aircraft means an aircraft to which the AD applies that is operated only in private operations.\n\n> Note private operation is defined in Part 1 of the CASR Dictionary.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
