Plain English Summary

3/10 complexity

This AD requires owners/operators and maintenance organisations of Beagle B121 series 1–3 aeroplanes with over 2,450 hours TIS to follow British Aerospace Service Bulletin B121/86: inspect the tailplane spar attachment area for cracks and carry out any corrective work. Inspections must begin within 50 hours after 8 June 1984 and repeat every 50 hours. It responds to in‑service rear fuselage cracking and shifts inspection/repair costs and downtime onto operators.
