A subsequent investigation by the manufacturer revealed that the float bags may contain inflation valves produced by two different manufacturers. These valves have different gas flow characteristics, and as a result, a combination of the two could result in an unequal float inflation if the system is actuated, with risk of overturn. Amendment 1 is issued to include Agusta Bell models in AD Applicability in response to the issue of the relevant RAI AD.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
