Airbus H160-B helicopters must now be inspected for cracks in their main gearbox supports
What happened
The US aviation regulator now requires repetitive inspections for cracks in the main gearbox supports of all Airbus H160-B helicopters. This means operators must check these parts regularly and fix them if cracks are found, or replace certain assemblies entirely.
Why it matters
This rule directly addresses a known safety issue with a specific helicopter model. It shifts the burden of identifying and fixing this problem from a potential accident investigation to mandatory, preventative maintenance. This kind of directive is how aviation regulators ensure that known design flaws are systematically addressed across an entire fleet, preventing future failures.
The signal
Watch for any reports of H160-B main gearbox failures after these inspections become mandatory, which would indicate the inspections are not sufficient.
