14 CFR Part 39

[Docket No. FAA-2020-0905; Project Identifier 2019-SW-102-AD; Amendment 
39-21384; AD 2021-02-01]

Airworthiness Directives; Airbus Helicopters

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2015-26-
01, which applied to certain Airbus Helicopters Model AS332C1, AS332L1, 
AS332L2, EC225LP, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters 
with an energy-absorbing seat. AD 2015-26-01 required inspecting for 
the presence of labels (placards) that prohibit stowing anything under 
the seat, and if a label (placard) is missing or not clearly visible to 
each occupant, installing a label (placard). This AD retains all of the 
requirements of AD 2015-26-01, and also adds helicopters to the 
applicability and requires a modification (installing new labels 
(placards)). This AD was prompted by the determination that additional 
helicopters are affected by the unsafe condition, and that new labels 
(placards) are required for all affected helicopters. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective April 6, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 6, 
2021.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of January 
26, 2016 (80 FR 79466, December 22, 2015).

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2015-26-01, Amendment 39-18349 (80 FR 
79466, December 22, 2015) (AD 2015-26-01). AD 2015-26-01 applied to 
certain Airbus Helicopters Model AS332C1, AS332L1, AS332L2, EC225LP, 
AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters with an energy-
absorbing seat. The NPRM published in the Federal Register on October 
7, 2020 (85 FR 63240). The NPRM was prompted by the discovery that 
required labels (placards) prohibiting stowage of any object under an 
energy-absorbing seat had not been systematically installed and the 
determination that additional helicopters are affected by the unsafe 
condition, and that new labels (placards) are required for all affected 
helicopters. The NPRM proposed to continue to require inspecting for 
the presence of labels (placards) that prohibit stowing anything under 
the seat, and if a label (placard) is missing or not clearly visible to 
each occupant, installing a label (placard), and also proposed to add 
helicopters to the applicability and require a modification (installing 
new labels (placards)). The FAA is issuing this AD to address any 
object stowed under an energy-absorbing seat, which could reduce the 
efficiency of the energy-absorbing function of the seat,

[[Page 12087]]

resulting in injury to the seat occupants during an accident. See the 
MCAI for additional background information.
    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2019-0088R1, dated November 8, 2019 (EASA AD 2019-0088R1) (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, AS332L1, AS332L2, EC225LP, 
AS-365N2, AS 365 N3, EC 155B and EC155B1 helicopters with an energy-
absorbing seat. EASA advised that during certification of an energy-
absorbing seat with a new part number, the labels (placards) that 
require keeping the space under the seat free of any object were not 
systematically installed. EASA stated that this condition, if not 
corrected, could prompt occupants to stow objects under an energy-
absorbing seat, which would reduce the effectiveness of the seat and 
the occupants' chance of surviving an accident. EASA consequently 
issued AD 2014-0204, dated September 11, 2014; corrected September 12, 
2014 (which corresponds to FAA AD 2015-26-01) to require a one-time 
inspection for the presence of labels (placards) and, if they were 
missing or unreadable, making and installing labels (placards) 
prohibiting the placing of an object under an energy absorbing seat. 
EASA later advised, in EASA AD 2017-0226, dated November 17, 2017 (EASA 
AD 2017-0226), which superseded EASA AD 2014-0204, that additional new 
labels (placards) were required and that additional helicopters were 
affected by the unsafe condition. In this MCAI, which supersedes EASA 
AD 2017-0226, EASA advised that additional extended compliance times 
were necessary for certain helicopters.
    You may examine the MCAI in the AD docket on the internet at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-0905.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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

    The FAA determined that 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.
