Plain English Summary

2/10 complexity

This AD requires owners of Bombardier DHC‑8 Series 100 and 300 aircraft to correct incorrect wiring in engine fire‑suppression systems per updated manufacturer procedures. It updates technical references and adds safeguards for maintenance to prevent future miswiring.

It affects all operators of these models and matters because proper wiring ensures extinguishing agents go to the burning engine, not the healthy one.
