Airbus helicopter parts must now be replaced more often, for more models

The US aviation regulator is tightening rules for certain Airbus helicopters. Operators must now replace specific main rotor gearbox parts more frequently, and the rule applies to more helicopter models than before.

Helicopter operators now face higher maintenance costs and more downtime for these specific models. This change means that a part previously thought to have a longer lifespan is now considered a recurring safety risk, forcing a shift in operational planning and budgets. It also expands the number of helicopters affected by these stricter safety checks.
