Airbus helicopters must get more frequent inspections for metal particles in their gearboxes

The US aviation regulator now requires more frequent inspections for certain Airbus helicopters. This means mechanics must check the main gearbox for metal particles more often, and some gearboxes cannot be installed unless they meet new requirements.

Helicopter gearboxes are complex and critical components. Small metal particles can indicate wear or damage that could lead to catastrophic failure. This rule means operators must now proactively detect potential problems before they become serious, increasing the operational cost of these specific helicopter models.
