summary: The FAA proposes to supersede Airworthiness Directive (AD) 2022-01-01, which
  applies to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3,
  AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, AS 365 N2, AS 365 N3,
  EC130B4, EC130T2, SA 365 C1, SA 365 C2, SA 365 N, and SA 365 N1 helicopters. AD
  2022-01-01 requires the application of alignment markings on, and repetitive inspections
  of, the main rotor (MR) pitch rod upper links and, depending on findings, the accomplishment
  of applicable corrective actions. Since the FAA issued AD 2022-01-01, the manufacturer
  designed a new pitch rod lever axis attachment screw and issued applicable modification
  material as an alternative option. This proposed AD would retain all the actions
  of AD 2022-01-01 and would allow the modification as a terminating action to the
  repetitive inspections and corrective actions. This proposed AD would also prohibit
  installing a certain affected pitch rod lever axis attachment screws unless certain
  requirements are met. The FAA is proposing this AD to address the unsafe condition
  on these products.
