Plain English Summary

1/10 complexity

What this does: This document officially cancels a previous safety rule (Airworthiness Directive AD/BELL 412/25) that required owners of Bell 412 helicopters to inspect bolts in the main rotor flight control system every 24 months.

Who it affects: Operators and owners of Bell Helicopter Textron 412 series helicopters.

What it means for you: If you own or operate one of these helicopters, you no longer need to perform these specific bolt inspections. The Civil Aviation Safety Authority has removed this requirement because there have been no reports of safety problems related to these bolts, meaning the mandatory inspections are no longer considered necessary.

Key date: The cancellation took effect on 19 November 2009.
