14 CFR Part 39

[Docket No. FAA-2020-0909; Project Identifier 2019-SW-118-AD; Amendment 
39-21458; AD 2021-05-15]

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 
helicopters. This AD was prompted by a report that the cabin lateral 
sliding plug door failed its emergency jettisoning test; subsequent 
investigation revealed that the jettison handle cable interfered with 
the cable clamps. This AD requires modifying the release system of each 
cabin lateral sliding plug door, or modifying the design of the 
jettison system of each cabin lateral sliding plug door, as specified 
in a European Union Aviation Safety Agency (EASA) AD, which is 
incorporated by reference. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective May 7, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 7, 2021.

SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0064R1, dated December 19, 2019 
(EASA AD 2019-0064R1) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and 
AS332L1 helicopters.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus 
Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. The 
NPRM published in the Federal Register on October 7, 2020 (85 FR 
63238). The NPRM was prompted by a report that the cabin lateral 
sliding plug door failed its emergency jettisoning test; subsequent 
investigation revealed that the jettison handle cable interfered with 
the cable clamps. The NPRM proposed to require modifying the release 
system of each cabin lateral sliding plug door, or modifying the design 
of the jettison system of each cabin lateral sliding plug door, as 
specified in EASA AD 2019-0064R1, which is incorporated by reference.
    The FAA is issuing this AD to address this condition, which could 
lead to jamming of the door jettisoning mechanism, preventing the 
jettisoning of the affected door in an emergency situation, and 
possibly obstructing occupant evacuation. See the MCAI for additional 
background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comment 
received. The commenter indicated support for the NPRM.

[[Page 17291]]

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0064R1 describes, among other things, procedures for 
modifying the release system of each cabin lateral sliding plug door, 
or modifying the design of the jettison system of each cabin lateral 
sliding plug door.
    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

Differences Between This AD and the MCAI

    EASA AD 2019-0064R1 specifies inspections of the jettisoning 
mechanism of the cabin lateral sliding plug doors and corrective 
actions. This AD does not include those actions. AD 2019-09-03, 
Amendment 39-19637 (84 FR 22693, May 20, 2019) (AD 2019-09-03) already 
requires those actions. The FAA has determined that this AD will only 
require the modification specified in EASA AD 2019-0064R1, which would 
then terminate the requirements of AD 2019-09-03.

Costs of Compliance

    The FAA estimates that this AD affects 19 helicopters of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per product         Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 214 work-hours x $85 per hour =               $ *   Up to $18,190.............  Up to $345,610.
 Up to $18,190.
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency to provide parts cost estimates for the
  actions specified in this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: General requirements. 
Under that section, Congress charges the FAA with promoting safe flight 
of civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
