ACTION: Final rule; request for comments. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2000-18-09, which applied to certain Bell Helicopter Textron, Inc. (now Bell Textron Inc.), Model 412, 412CF, and 412EP helicopters. AD 2000-18-09 required repetitively inspecting the upper left-hand cap angle (cap angle) and adjacent structure for a crack and, depending on the results, replacing any cracked cap angle and repairing any crack in the adjacent structure. This AD was prompted by a report of a fatigue crack in a tail boom attachment cap angle. This AD retains the requirements of AD 2000-18-09, expands the applicability by adding models and an additional part-numbered cap angle, reduces the inspection intervals, and requires using updated procedures. This AD also updates the reporting requirement. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective September 4, 2024. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 4, 2024.
