Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, AS-365N2, AS 
365 N3, SA-365N, SA-365N1, EC 155B, and EC155B1 helicopters. This AD 
was prompted by investigation results from an engine compartment fire, 
which determined some of the internal parts of the engine upper fixed 
cowling (engine cowling) were painted with finish paint on top of the 
primer layer. This AD requires a one-time inspection of certain part-
numbered engine cowlings, and corrective actions if necessary, 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 July 13, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 13, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0265, dated November 23, 2021 
(EASA AD 2021-0265), to correct an unsafe condition for Airbus 
Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale, 
Sud Aviation, Model SA 365 N, SA 365 N1, AS 365 N2, AS 365 N3, EC 155 
B, EC 155 B1, AS 355 E, AS 355 F, AS 355F 1 and AS 355 F2 helicopters, 
all serial numbers.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus Helicopters 
Model AS355E, AS355F, AS355F1, AS355F2, AS-365N2, AS 365 N3, SA-365N, 
SA-365N1, EC 155B, and EC155B1 helicopters. The NPRM published in the 
Federal Register on March 29, 2022 (87 FR 17955). The NPRM was prompted 
by investigation results from an engine compartment fire, which 
determined some of the internal parts of the engine cowling were 
painted with finish paint on top of the primer layer. The NPRM proposed 
to require a one-time inspection of certain part-numbered engine 
cowlings, and corrective actions if necessary, as specified in EASA AD 
2021-0265.
    The FAA is issuing this AD to detect finish paint inside the duct 
of the engine cowling. The unsafe condition, if not addressed, could 
result in fire

[[Page 34771]]

propagation in case of exposure to high temperature, damage to the 
helicopter, and injury to the occupants. See EASA AD 2021-0265 for 
additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA reviewed the relevant 
data and determined that air safety requires adopting this AD as 
proposed, except for minor editorial changes. Accordingly, the FAA is 
issuing this AD to address the unsafe condition on these helicopters.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0265 requires a one-time inspection of certain part-
numbered engine cowlings (e.g., an affected part as defined in EASA AD 
2021-0265) for finish paint and depending on the inspection results, 
accomplishment of applicable corrective actions. EASA AD 2021-0265 also 
allows an affected part to be installed on any helicopter, provided it 
is a serviceable part as defined in EASA AD 2021-0265. Corrective 
actions include repainting the affected part and replacing the affected 
part.
    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.

Other Related Service Information

    The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB) 
No. AS355-53.00.38, ASB No. AS365-53.00.65, and ASB No. EC155-53A040, 
all Revision 0, and all dated October 27, 2021, which specify 
procedures for inspecting the inside of the duct of the engine cowling 
for finish paint and corrective actions.

Differences Between This AD and EASA AD 2021-0265

    Service information referenced in EASA AD 2021-0265 specifies 
recording compliance with the applicable ASBs, whereas this AD does 
not.

Costs of Compliance

    The FAA estimates that this AD affects 93 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Inspecting each engine cowling takes about 1 work-hour for an 
estimated cost of $85 per helicopter and $7,905 for the U.S. fleet.
    Repainting each engine cowling with primer takes about 8 work-hours 
for an estimated cost of $680 per helicopter.
    Replacing an engine cowling with a ``serviceable part'' as defined 
in EASA AD 2021-0265 takes about 4 work-hours and parts cost up to 
$7,800 for an estimated cost of up to $8,140 per replacement.

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.
