Airworthiness Directives; Yabor[atilde] Ind[uacute]stria 
Aeron[aacute]utica S.A. (Type Certificate Previously Held by Embraer 
S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2018-19-28, which applies to certain Embraer S.A. Model ERJ 190-100 
STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW 
airplanes; and AD 2014-16-16, which applies to all of those airplane 
models. AD 2014-16-16 requires, for certain airplanes, retorquing and 
replacing the pylon lower link fittings, and for all airplanes, 
repetitively retorquing those fittings. AD 2018-19-28 requires 
modifying the attaching parts of the pylon lower link fittings. Since 
the FAA issued AD 2014-16-16 and AD 2018-19-28, the FAA finds it 
necessary to change the compliance time for the modification. This 
proposed AD would require an inspection of certain shear pins, 
replacement if necessary, and revised compliance times for the 
modification, as specified in an Ag[ecirc]ncia Nacional de 
Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for 
incorporation by reference. The FAA is proposing this AD to address the 
unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by October 8, 
2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    The FAA issued AD 2014-16-16, Amendment 39-17940 (79 FR 48018, 
August 15, 2014) (AD 2014-16-16), which applies to all Embraer S.A. 
Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, 
and -200 IGW airplanes. AD 2014-16-16 requires, for certain airplanes, 
retorquing and replacing the pylon outboard and inboard lower link 
fittings, and for all airplanes, that AD also requires repetitive 
retorquing of the pylon outboard and inboard lower link fittings. The 
FAA issued AD 2014-16-16 to prevent loss of a shear pin on the pylon 
outboard and inboard lower link fittings, which could result in failure 
of the fitting and consequent separation of the engine from the wing.
    The FAA also issued AD 2018-19-28, Amendment 39-19429 (83 FR 48935, 
September 28, 2018) (AD 2018-19-28), which applies to certain Embraer 
S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 
LR, and -200 IGW airplanes. AD 2018-19-28 requires modification of the 
attaching parts of the left-hand (LH) and right-hand (RH) pylon lower 
link fittings, inboard and outboard positions. The FAA issued AD 2018-
19-28 to prevent loss of integrity of the engine pylon lower link 
fittings, possibly resulting in separation of the engine from the wing. 
AD 2018-19-28 specified that accomplishing certain actions required by 
that AD terminated certain requirements of AD 2014-16-16.

Actions Since ADs 2014-16-16 and 2018-19-28 Were Issued

    Since the FAA issued ADs 2014-16-16 and 2018-19-28, cracked nuts 
and an external shear pin with damaged threads were found when the 
pylon outboard and inboard lower link fittings were retorqued. In 
addition, the FAA finds it necessary to change the compliance time for 
the modification of the pylon lower link fitting attaching parts, in 
order to prevent loss of integrity of the engine pylon lower link 
fittings.
    ANAC, which is the aviation authority for Brazil, has issued ANAC 
AD 2020-06-02R02, effective November 30, 2020 (ANAC AD 2020-06-02R02) 
(also referred to as the Mandatory Continuing Airworthiness 
Information, or the MCAI), to correct an unsafe condition for certain 
Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. Model ERJ 190-
100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW 
airplanes. ANAC AD 2020-06-02R02 supersedes ANAC AD 2014-07-01 (which 
corresponds to FAA AD 2014-16-16) and ANAC AD 2017-01-01 (which 
corresponds to FAA AD 2018-19-28). Model 190-100 SR airplanes are not 
certificated by the FAA and are not included on the U.S. type 
certificate data sheet; this AD therefore does not include those 
airplanes in the applicability.
    This proposed AD was prompted by reports of bushing migration, loss 
of nut torque on the engine pylon lower inboard and outboard link 
fittings, a loose lower link assembly, and damaged nuts. The existing 
torque values could cause damage to the nuts, which could lead to loss 
of the shear pins of the pylon outboard and inboard lower link 
fittings. In addition, the existing compliance time for the 
modification of the pylon lower link fitting attaching parts has been 
found to be inadequate to address the unsafe condition. The FAA is 
proposing this AD to prevent loss of integrity of the lower link 
fittings of the engine pylon, which could result in separation of the 
engine from the wing. See the MCAI for additional background 
information.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of ADs 2014-16-16 and 2018-19-28, this proposed AD would 
retain all of the requirements of AD 2014-16-16 and AD 2018-19-28. 
Those requirements are referenced in ANAC AD 2020-06-02R02, which, in 
turn, is referenced in paragraph (g) of this proposed AD.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2020-06-02R02 describes procedures for: Reduction of the 
torque to be applied to the castellated nuts of the external shear 
pins; inspection of the external shear pin; modification of the 
attaching parts of the LH and RH pylon lower link fittings, inboard and 
outboard positions; and repetitive retorquing of the pylon outboard and 
inboard lower link fittings.
    This AD also requires Embraer Service Bulletin 190-54-0013, dated 
November 27, 2012; and Embraer Service Bulletin 190LIN-54-0004, dated 
December 20, 2012; which the Director of the Federal Register approved 
for incorporation by reference as of September 2, 2014 (79 FR 48018, 
August 15, 2014).
    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.

Explanation of Change to Manufacturer's Name Specified in This NPRM

    The FAA has revised references to the manufacturer's name specified 
throughout this NPRM to identify the manufacturer name as published in 
the most recent type certificate data sheet for the affected models.

[[Page 47254]]

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 FAA's 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 pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in ANAC AD 2020-06-02R02 described previously, as proposed for 
incorporation by reference, 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.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate ANAC AD 2020-06-02R02 by reference in the 
FAA final rule. This proposed AD would, therefore, require compliance 
with ANAC AD 2020-06-02R02 in its entirety through that incorporation, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Service information required by ANAC AD 2020-
06-02R02 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0692 after the FAA final rule is published.

Differences Between This Proposed AD and the MCAI

    The applicability of ANAC AD 2020-06-02R02 is limited to certain 
airplanes of the affected models. However, the applicability of this 
proposed AD includes all airplanes. Because the affected lock 
assemblies are rotable parts, the FAA has determined that these parts 
could later be installed on airplanes that were initially delivered 
with the acceptable lock assemblies, thereby subjecting those airplanes 
to the unsafe condition. The FAA has confirmed that the requirement in 
paragraph (w) of ANAC AD 2020-06-02R02 is applicable to the expanded 
group of airplanes.

Costs of Compliance

    The FAA estimates that this proposed AD affects 85 airplanes 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.

                                      per hour = Up to $22,950.                                       $2,222,750
New proposed actions...............  Up to 274 work-hours x $85     Up to $3,180   Up to $26,470           Up to
                                      per hour = Up to $23,290.                                       $2,249,950
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions specified in this proposed AD.
    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) 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.

send your request to your principal inspector or responsible Flight 
Standards Office, as appropriate. If sending information directly to 
the Large Aircraft Section, International Validation Branch, send it 
to the attention of the person identified in paragraph (k)(2) of 
this AD. Information may be emailed to: <a href="/cdn-cgi/l/email-protection#b98094f8efea94f8f0eb948e8a8994f8f4f6faf9dfd8d897ded6cf"><span class="__cf_email__" data-cfemail="380115796e6b1579716a150f0b08157975777b785e5959165f574e">[email protected]</span></a>. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, Large Aircraft 
Section, International Validation Branch, FAA; or ANAC; or ANAC's 
authorized Designee. If approved by the ANAC Designee, the approval 
must include the Designee's authorized signature.
    (3) Required for Compliance (RC): Except as specified by 
paragraph (h) of this AD: For service information that contains 
steps that are labeled as Required for Compliance (RC), the 
provisions of paragraphs (j)(3)(i) and (ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
