Plain English Summary

4/10 complexity

Owners/operators of Piaggio P.166 aircraft with serial numbers before 409 must immediately install independent circuit protection for the turn-and-bank, NK fire‑warning, and stall‑warning systems under a Civil Aviation Safety Authority airworthiness directive. Maintenance organisations and certifying engineers will perform and record the work, which imposes up‑front costs and downtime on operators but aims to reduce the risk that a single electrical fault disables multiple safety‑critical systems.
