Plain English Summary

3/10 complexity

This AD requires owners/operators of Beagle B121 Series 1–3 aeroplanes to carry out Jetstream Aircraft Mandatory Service Bulletin B121/103, enforced via the Schedule of Airworthiness Directives, to address the risk of cracked brake torque‑tube assemblies.

It affects those owners/operators and their maintenance providers; inspections, repairs or replacements and any downtime are mandatory and paid by operators. The AD delegates technical detail (intervals, actions, parts) to the service bulletin, so exact costs and timing depend on that document.
