Airbus helicopters must replace faulty main gearbox parts, cannot reuse old ones

The US aviation regulator is ordering specific Airbus helicopter models to replace certain parts in their main gearbox suspension. This means operators cannot simply reinstall old parts, even if they appear functional, and must use new ones.

This is a safety mandate for a specific helicopter model. It forces operators to spend money on new parts, rather than inspecting and reusing existing ones. This type of directive is common in aviation, where even small mechanical failures can have catastrophic consequences.
