ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2002-08-16 for certain Eurocopter France SA341G, SA342J, and SA-360C helicopters. AD 2002-08-16 required removing certain main rotor head torsion tie bars (tie bars) from service and revising the limitations section of the existing maintenance manual for your helicopter by adding life limits for certain other tie bars. This AD was prompted by the determination that another part-numbered tie bar is affected by the same unsafe condition. This AD continues to require removing certain tie bars from service and establishing a life limit for certain other tie bars. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 10, 2021.
