Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Helicopters Model EC155B1 helicopters. This proposed 
AD was prompted by a report of difficulties when jettisoning the co-
pilot door during non-scheduled maintenance. This proposed AD would 
require 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 proposed for incorporation 
by reference (IBR). The FAA is proposing this AD to address the unsafe 
condition on these products.

Discussion

    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.
    This proposed AD was prompted by a report of difficulties when 
jettisoning the co-pilot door during non-scheduled maintenance. The FAA 
is proposing 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.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2015-0157 describes 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD after evaluating all the 
relevant information and determining the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2015-0157, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2015-0157 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2015-0157 in its 
entirety, through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this proposed AD. 
Using common terms that are the same as the heading of a particular 
section in the EASA AD does not mean that operators need comply only 
with that section. For example, where the AD requirement refers to 
``all required actions and compliance times,'' compliance with this AD 
requirement is not limited to the section titled ``Required Action(s) 
and Compliance Time(s)'' in the EASA AD. Service information specified 
in EASA AD 2015-0157 that is required for compliance with EASA AD 2015-
0157 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2021-0314 after the FAA 
final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 14 helicopters of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed 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
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85......              $0              $85
------------------------------------------------------------------------

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
