## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2021-11-25, which applies to certain Airbus Helicopters (type certificate previously held by Eurocopter France) Model AS350B3 and EC130T2 helicopters. AD 2021-11-25 requires revising the existing rotorcraft flight manual (RFM) for your helicopter by inserting a new procedure (temporary). Since the FAA issued AD 2021-11-25, the manufacturer has identified an additional affected full authority digital engine control (FADEC) part number and developed an optional modification for the affected FADECs. This proposed AD would require revising the existing RFM for your helicopter by inserting a new procedure (temporary). This proposed AD would also require, for helicopters on which an optional terminating action (installation of serviceable FADECs) is done, removing the applicable temporary procedure from the existing RFM for your helicopter. In addition, this proposed AD would also add helicopters to the applicability. Furthermore, this proposed AD would prohibit the installation of an affected FADEC. The FAA is proposing this AD to address the unsafe condition on these products.
