Airworthiness Directives; Airbus Helicopters Type Certificate Previously Held by Eurocopter France and Eurocopter France Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is superseding Airworthiness Directive AD 200208
16 for certain Eurocopter France SA341G, SA342J, and SA360C
helicopters. AD 20020816 required removing certain main rotor head torsion tie bars tie bars from service and revising the limitations section of the existing maintenance manual for your helicopter by adding life limits for certain other tie bars. This AD was prompted by the determination that another part-numbered tie bar is affected by the same unsafe condition.
This AD continues to require removing certain tie bars from service and establishing a life limit for certain other tie bars. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background The FAA issued a supplemental notice of proposed rulemaking SNPRM
to amend 14 CFR part 39 to supersede AD 20020816 67 FR 19640, April 23, 2002 AD 20020816. AD 200208
16 applied to Eurocopter France Model SA341G, SA342J, and SA360C
helicopters with a tie bar part number P/N 341A31490400, 01, 02, 03;
341A31493300, 01; or 360A31
109702, 03, installed. The SNPRM
published in the Federal Register on May 20, 2021 86 FR 27323. The FAA
preceded the SNPRM with a notice of proposed rulemaking NPRM that published in the Federal Register on May 10, 2006 71 FR 27215. The SNPRM proposed to continue to require removing tie bar P/Ns 341A31490400, 01, 02, and 03; and 360A31109702
and 03 from service. The SNPRM also proposed to prohibit installing those part-numbered tie bars on any helicopter. The SNPRM proposed to initially require removing tie bar P/Ns 341A31493300 and 01; and 704A33
633270 from service if they have accumulated or exceeded the specified life limit, and thereafter removing those part-numbered tie bars from service

before accumulating the specified life limit.
The SNPRM was prompted by a significant amount of time that had elapsed since issuance of the NPRM that required the FAA to reopen the comment period to allow the public a chance to comment on the proposed actions. Additional review also revealed necessary changes to address the unsafe condition. The SNPRM proposed to clarify that the compliance times of requirements continued from AD 2002
0816 are effective after the effective date of AD 20020816, clarify instances of life limits specified in calendar time that they are since initial installation of the tie bar on any helicopter, clarify one instance of a life limit that it is total hours time-in-service TIS or calendar timewhichever occurs first, and add parts installation prohibitions. The SNPRM also updated the AD format. As a result, paragraph identifiers changed, editorial changes were made to meet current publishing requirements, and the proposed requirements were revised by removing unnecessary information.
The NPRM was prompted by DGAC
AD 2001587041A R2, dated January 8, 2003 DGAC AD 2001587041A
R2, issued by the DGAC, which was the Technical Agent for France, to correct an unsafe condition for Model SA 341/
342 helicopters. The DGAC advised of another affected tie-bar P/N 704A33
633270 and additional flight restrictions for the newly-affected tie bar. This condition, if not addressed, could result in failure of a tie bar and subsequent loss of control of the helicopter. Accordingly, DGAC AD
2001587041A R2, along with DGAC
AD 2001588047A R1, dated December 26, 2001 DGAC AD 2001
588047A R1, for Model SA 360
helicopters, require removing certain part-numbered tie bars from service and a life limit for certain other partnumbered tie bars.
Discussion of Final Airworthiness Directive Comments The FAA received no comments on the SNPRM or on the determination of the costs.
Conclusion These helicopters have been approved by the European Union Aviation Safety
