- What it does
The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these airplanes. This AD was prompted by a report of several missing or broken high pressure valve (HPV) butterfly clips found in a repair shop. This AD prohibits dispatching an airplane under certain dispatch provisions corresponding to master minimum equipment list (MMEL) items for the wing anti-ice system, wing anti ice pressure sensor, fan air valve (FAV), bleed air systems, engine bleed pressure regulating shutoff valve (PRSOV), HPV, and pack bleed air leak and overheat detection loop; and prohibits dispatching an airplane if certain crew alerting system (CAS) messages and associated info messages are displayed. The FAA is issuing this AD to address the unsafe condition on these products.
