Airbus helicopters get a permanent fix for a fan blade problem, ending repeated inspections

US aviation regulators propose a new rule that would require Airbus SA330J helicopter owners to install an improved main gearbox fan bearing assembly. This new part would eliminate the need for repeated inspections of the fan blades, which were previously required due to a known defect. The change means helicopter operators will replace a part once instead of performing ongoing checks.

For years, operators of these helicopters had to repeatedly check a specific part for a known flaw. This new rule means they can install a permanent fix. This shifts the burden from ongoing maintenance checks to a one-time upgrade, potentially reducing operational costs and downtime for these aircraft.
