Plain English Summary

4/10 complexity

This directive requires immediate modification of DH 84 (Dragon) series aeroplanes’ fuel-control installation: secure and clamp the fuel-control cable housing at both ends and its wing-entry bend, and fit a pilot fuel‑lever lock that holds ON yet still allows rapid movement to OFF. It affects DH 84 owners/operators (who must fund and schedule the work), aims to reduce cable loosening and prevent delayed shut‑offs, and was issued by the Civil Aviation Safety Authority.
