Airbus helicopters must replace a critical part after a ball joint failed

The US aviation regulator wants to force Airbus helicopter operators to replace a specific part on several models. This change comes after a ball joint failed, which could cause a helicopter to crash.

Helicopter parts fail. When they do, regulators often issue airworthiness directives. This one is specific: it targets a known failure point in a critical assembly. Operators will have to pay for the replacement, which means higher maintenance costs for these specific Airbus models.
