Airbus helicopter parts must now be checked for wear, not just replaced on schedule

The US aviation regulator now requires specific helicopter parts to be inspected for wear, rather than replaced on a fixed schedule. This means operators must measure the wear on control rod and pitch link spherical bearings and report the results, taking action only if needed.

For years, many aircraft parts were replaced based on a set number of flight hours, regardless of their actual condition. This new rule shifts the maintenance approach for these critical helicopter components from time-based replacement to condition-based inspection. It means that parts might stay in service longer if they show no wear, or be replaced sooner if they do, potentially changing maintenance costs and schedules for operators.
