Abstract
The FAA is superseding Airworthiness Directive (AD) 2018-07- 08, which applied to certain Leonardo S.p.A (type certificate previously held by Agusta S.p.A) Model A109E, A109K2, A109S, AW109SP, A119, and AW119 MKII helicopters. AD 2018-07-08 required reducing the life limit of the tail rotor blade retention bolt and an inspection of that bolt for cracking, and replacement of any cracked bolt. This AD continues to require reducing the life limit of the tail rotor blade retention bolt, inspecting that bolt for cracking, and replacing any cracked bolt. In addition, this AD requires repetitive inspections of the tail rotor blade retention bolt for cracking. The FAA is issuing this AD to address the unsafe condition on these products.
