The Federal Aviation Administration is updating a mandatory safety rule (called an airworthiness directive) for Leonardo helicopters. The new rule requires operators to repeatedly check a specific structural joint for cracks and to install a manufacturer-approved modification that permanently stops the cracking. Once the modification is installed, the repetitive inspections are no longer required.

Why it matters: This rule changes maintenance schedules for helicopter operators. Instead of just checking for cracks indefinitely, owners must now install a specific fix that ends the inspection requirement. For most operators, this means a one-time modification cost followed by simpler paperwork, though the FAA notes the fix must be done on a set schedule. The economic impact on small businesses is considered minimal.

Who it affects

  • Operators and maintenance facilities for Leonardo S.p.A. helicopters, including the A109E and additional models added by this rule
