Airbus helicopters get new parts to fix old design flaws
What happened
The US aviation regulator is forcing Airbus to replace specific parts on some of its older helicopters. This means certain main gearbox suspension bar fittings and bolts must be modified or replaced with newly designed ones.
Why it matters
Helicopter parts wear out, but some wear out faster than expected, creating an unsafe condition. This rule means operators cannot just keep replacing the old parts; they must install a new design. It shifts the burden from repeated maintenance to a one-time fix that should last longer.
The signal
Watch for any further airworthiness directives on these specific helicopter models, which would indicate if the new parts solve the underlying issue or if more problems emerge.
