Airbus Helicopters (Type Certificate Previously Held by Eurocopter France) Helicopters
This AD applies to Airbus Helicopters (type certificate previously held by Eurocopter France) Model AS350B3 and EC130T2 helicopters, certificated in any category, with an ARRIEL 2D engine and with THALES full authority digital engine control (FADEC) part number (P/N) C13165DA00 without amendment A, P/N C13165DA00PC00 without amendment A, or P/N C13165FA00 without amendment B, that has a serial number below 1736, installed.
Note 1 to paragraph (c): Helicopters with a Model AS350B3e designation are Model AS350B3 helicopters.
The FAA is superseding Airworthiness Directive (AD) 2021-11- 25, which applied to certain Airbus Helicopters (type certificate previously held by Eurocopter France) Model AS350B3 and EC130T2 helicopters. AD 2021-11-25 required 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 identified an additional affected full authority digital engine control (FADEC) part number and developed an optional modification for the affected FADECs. This AD requires revising the existing RFM for your helicopter by inserting a new procedure (temporary). This AD also requires, for helicopter on which an optional terminating action (installation of serviceable FADECs) was done, removing the applicable temporary procedure from the existing RFM for your helicopter. In addition, this AD also adds helicopters to the applicability. Furthermore, this AD prohibits the installation of an affected FADEC. The FAA is issuing this AD to address the unsafe condition on these products.
For helicopters with FADEC P/N C13165DA00 without amendment A or P/N C13165FA00 without amendment B installed:
(1) Within 25 hours time-in-service after July 29, 2021 (the effective date of AD 2021-11-25), revise the Emergency Procedures of the existing RFM for your helicopter by inserting Appendix 4. of Airbus Helicopters Alert Service Bulletin (ASB) No. AS350-01.00.67 or ASB No. EC130-04A004, each Revision 2 and dated February 17, 2014 (ASB AS350-01.00.67 or ASB EC130-04A004), as applicable to your helicopter model. Inserting a different document with information identical to that in Appendix 4. of ASB AS350-01.00.67 or ASB EC130-04A004, as applicable to your helicopter model, is acceptable for compliance with the requirement of this paragraph.

Inserting a different document with information identical to that in Appendix 4. of ASB AS350-01.00.67 or ASB EC130-04A004, as applicable to your helicopter model, is acceptable for compliance with the requirement of this paragraph.
