Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Helicopters Model EC155B1 helicopters. This AD was 
prompted by a report of difficulties when jettisoning the co-pilot door 
during non-scheduled maintenance. This AD requires a functional check 
of the pilot and co-pilot door jettisoning system and corrective 
actions if necessary, as specified in a European 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 20, 2021.

    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 20, 
2021.

SUPPLEMENTARY INFORMATION:

Background

    The EASA (now European Union Aviation Safety Agency), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2015-0157, dated July 30, 2015 (EASA AD 2015-0157) (also 
referred to as the Mandatory Continuing Airworthiness Information, or 
the MCAI), to correct an unsafe condition for Airbus Helicopters Model 
EC 155 B1 helicopters, all serial numbers delivered after manufacturing 
before June 30, 2015, and equipped with a pilot or co-pilot door 
jettisoning system in accordance with Airbus Helicopters Modification 
POST MOD 0752C05, except helicopters on which Aircraft Maintenance 
Manual (AMM) Task 52-11-00-712 was accomplished on both pilot and co-
pilot doors since the last crew door installation.
    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 EC155B1 helicopters. The NPRM published in the 
Federal Register on April 22, 2021 (86 FR 21240). The NPRM was prompted 
by a report of difficulties when jettisoning the co-pilot door during 
non-scheduled maintenance. The NPRM proposed to require a functional 
check of the pilot and co-pilot door jettisoning system and corrective 
actions if necessary, as specified in an EASA AD.
    The FAA is issuing this AD to address jamming of the affected door 
jettisoning mechanism, which could reduce the ability of the flightcrew 
to evacuate in the event of an emergency situation. See the MCAI for 
additional background information.

Discussion of Final Airworthiness Directive

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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2015-0157 specifies procedures for doing a functional check 
of the pilot and co-pilot door jettisoning system and corrective 
actions. The corrective actions include greasing the tenons and 
restoring the jettison system. 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.

Costs of Compliance

    The FAA estimates that this AD affects 14 helicopters of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
8 work-hours x $85 per hour = $680...........................              $0             $680           $9,520
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
helicopters that might need this on-condition action:

                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                                  Labor cost                                       Parts cost        product
----------------------------------------------------------------------------------------------------------------

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.

accomplish those instructions, for this AD, the option is to repair 
the jettison system in accordance with FAA-approved procedures.
    (5) Where the service information referenced in EASA AD 2015-
0157 specifies to ``speak to Airbus Helicopters,'' this AD requires 
repairing the jettison system in accordance with FAA-approved
