Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening 
of comment period.

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

SUMMARY: The FAA is revising an earlier proposal to supersede 
Airworthiness Directive (AD) 2014-12-12, which applies to certain 
Airbus Helicopters Model EC120B and EC130B4 helicopters. This action 
revises the notice of proposed rulemaking (NPRM) by revising the 
compliance time, expanding the applicability, and providing improved 
procedures for modifying the sliding door star support as specified in 
a European Union Aviation Safety Agency (EASA) AD, which will be 
incorporated by reference. The FAA is proposing this AD to address the 
unsafe condition on these products. Since these actions would impose an 
additional burden over those in the NPRM, the FAA is reopening the 
comment period to allow the public the chance to comment on these 
changes.

DATES: The comment period for the NPRM published in the Federal 
Register on October 26, 2016 (81 FR 74362), is reopened.
    The FAA must receive comments on this SNPRM by November 6, 2020.

    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, as well 
as a report summarizing each substantive public contact with FAA 
personnel concerning this proposed rulemaking. Before acting on this 
proposal, the FAA will consider all comments received by the closing 
date for comments. The FAA will consider comments filed after the

[[Page 59455]]

comment period has closed if it is possible to do so without incurring 
expense or delay. The FAA may change this NPRM because of those 
comments.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to David 
Hatfield, Aviation Safety Engineer, Rotorcraft Standards Branch, FAA, 
10101 Hillwood Pkwy., Fort Worth, TX 76177; telephone 817-222-5116; 
email david.hatfield@faa.gov. Any commentary that the FAA receives 
which is not specifically designated as CBI will be placed in the 
public docket for this rulemaking.

Discussion

    The FAA issued AD 2014-12-12, Amendment 39-17873 (79 FR 36638, June 
30, 2014) (``AD 2014-12-12''). AD 2014-12-12 requires actions to 
address an unsafe condition on certain Airbus Helicopters Model EC120B 
and EC130B4 helicopters. AD 2014-12-12 requires inspecting the upper 
and lower locking pin control rod fittings for a bend, twist, or 
breakage and the star support pin for a crack; replacing control rod 
end fittings and star support pins if necessary; and reinforcing the 
sliding door star support stringer by installing three carbon fabric 
plies.
    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to 
supersede AD 2014-12-12 that would apply to certain Airbus Helicopters 
Model EC120B and EC130B4 helicopters. The NPRM published in the Federal 
Register on October 26, 2016 (81 FR 74362) (``the NPRM''). The NPRM was 
prompted by a report of passengers not being able to open a 
helicopter's left-hand door after landing. The NPRM proposed to require 
inspecting each upper and lower locking pin control rod end fitting and 
replacing it if necessary, cleaning and dye-penetrant inspecting the 
star support pin for cracking and replacing it if necessary, and 
reinforcing the sliding door star support stringer.

Actions Since Previous NPRM Was Issued

    Since the FAA issued the NPRM, there have been several incidents 
involving helicopter left-hand doors (both swinging and sliding) that 
revealed weaknesses in the locking mechanism. The FAA has determined 
the NPRM must be revised by revising the compliance time, expanding the 
applicability, and providing improved procedures for modifying the 
sliding door star support.
    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0095, dated April 29, 2020 
(``EASA AD 2020-0095'') (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Airbus Helicopters Model EC120B and 
EC130B4 helicopters. EASA advises that, after landing, the passengers 
on an Airbus Helicopters Model EC120B helicopter could not open the 
sliding door from inside. The passengers had to leave the helicopter 
through the other door. The results of the subsequent investigation 
revealed failure of a sliding door star axle support. This condition, 
if not corrected, could delay the evacuation from the helicopter in 
case of emergency, possibly resulting in injury to the occupants.
    EASA AD 2020-0095 superseded EASA AD 2015-0020, dated February 11, 
2015 (``EASA AD 2015-0020''), which corresponds to FAA NPRM, Docket No. 
FAA-2016-3343. EASA AD 2015-0020 superseded EASA AD 2013-0093, dated 
April 15, 2013; corrected April 17, 2013, which corresponds to FAA AD 
2014-12-12.
    EASA AD 2020-0095 revises the compliance time that was specified in 
EASA AD 2015-0020 and expands the applicability.
    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-2016-3343.
    This proposed AD was prompted by a report of passengers not being 
able to open a helicopter's left-hand door after landing. The FAA is 
proposing this AD to address failure of the sliding door star support, 
which could inhibit the operation of the sliding door from the inside, 
delaying the evacuation of passengers during an emergency. See the MCAI 
for additional background information.

Related Material Under 1 CFR Part 51

    EASA AD 2020-0095 describes improved procedures for modifying the 
door locking/unlocking mechanism (e.g. modifying the sliding door star 
support by installing a reinforcing bracket and replacing rod ends). 
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.

Comments

    The FAA gave the public the opportunity to participate in 
developing this proposed AD. The following presents the comment 
received on the NPRM and the FAA's response to that comment.

Request To Refer to Revised Service Information

    Airbus Helicopters proposed that the service information specified 
in the NPRM be revised because it was not the current revision level. 
The commenter stated that revising the service information to reflect 
the current revision level would prevent having to revise the final 
rule in the near future. The commenter explained that Airbus 
Helicopters Alert Service Bulletin EC120-52A018, Revision 01; and Alert 
Service Bulletin EC130-52A019, Revision 01, were released July 12, 
2016, and included improved procedures for replacing the rod ends and 
installing the reinforcements of the sliding door star support. The 
commenter noted that the revised service information also included 
additional helicopters in the effectivity.
    The FAA acknowledges the commenter's concern regarding the revision 
level of the service information specified in the proposed AD (in the 
NPRM). Since the FAA issued the NPRM, the AD format has changed and 
instead of specifying the required service information in paragraph 
(g), Requirements, of this proposed AD (SNPRM), operators would be 
required to comply with all required actions and compliance times 
specified in, and in accordance with, EASA AD 2020-0095, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD and except as discussed under ``Differences Between This 
Proposed AD and the MCAI.'' EASA AD 2020-0095 specifies that operators 
must use Airbus Helicopters Alert Service Bulletin EC120-52A018, 
Revision 01; and Alert Service Bulletin EC130-52A019, Revision 01, both 
dated July 12, 2016, as the required service information. The FAA has 
not changed

[[Page 59456]]

this proposed AD (SNPRM) in regard to this issue.

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 because the FAA 
evaluated all the relevant information and determined 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 2020-0095 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD and except as discussed under ``Differences 
Between this Proposed AD and the MCAI.''

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 2020-0095 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0095 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 2020-0095 that is required for compliance with EASA AD 2020-
0095 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2016-3343 after the FAA 
final rule is published.

Differences Between This Proposed AD and the MCAI

    EASA AD 2020-0095 specifies to do the modification within 24 
months. This proposed AD would require the modification be done within 
460 hours time-in-service (TIS), based on an average of 230 hours TIS 
per year. The FAA has determined this compliance time represents the 
maximum interval of time allowable for the affected helicopters to 
continue to safely operate before the modification is done.

Costs of Compliance

    The FAA estimates that this proposed AD affects 355 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
----------------------------------------------------------------------------------------------------------------
20 work-hours x $85 per hour = $1,700........................            $642           $2,342         $831,410
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators. The FAA does not control warranty 
coverage for affected operators. As a result, the FAA has included all 
known costs in the cost estimate.

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) 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.

List of Subjects in 14 CFR Part 39
