Abstract

The FAA is superseding Airworthiness Directive (AD) 2014-16- 16, which applied to all Embraer S.A. Model ERJ 190-100 STD, -100 LR, - 100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes; and AD 2018-19-28, which applied 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 2014-16-16 required, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitive retorquing of those fittings. AD 2018-19-28 required modification of the attaching parts of the pylon lower link fittings. This AD continues to require those actions, and also requires application of a lower torque value, inspection of certain shear pins and 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 incorporated by reference. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Background

    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 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. 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.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2014-16-16, Amendment 39-17940 (79 FR 
48018, August 15, 2014) (AD 2014-16-16); and AD 2018-19-28, Amendment 
39-19429 (83 FR 48935, September 28, 2018) (AD 2018-19-28). AD 2014-16-
16 applied 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 2018-19-28 
applied to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 
ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The NPRM 
published in the Federal Register on August 24, 2021 (86 FR 47252). The 
NPRM 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 NPRM proposed to continue to require the 
requirements of ADs 2014-16-16 and 2018-19-28, as specified in ANAC AD 
2020-06-02R02. The NPRM also proposed to require application of a lower 
torque value, inspection of certain shear pins and replacement if 
necessary, and revised compliance times for the modification, as 
specified in ANAC AD 2020-06-02R02. The NPRM also proposed to prohibit 
the installation of affected parts.
    The FAA is issuing this AD to address loss of integrity of the 
engine pylon lower link fittings, which could lead to separation of the 
engine from the wing. See the MCAI for additional background 
information.

Discussion of Final Airworthiness Directive

Comments

    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 
requires adopting this AD as proposed. Except for minor editorial 
changes, this AD is adopted as proposed in the NPRM. None of the 
changes will increase the economic burden on any operator. Accordingly, 
the FAA is issuing this AD to address the unsafe condition on these 
products.

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 left-hand (LH) and right-hand (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.

Costs of Compliance

    The FAA estimates that this AD affects 85 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                          Estimated Costs for Required Actions
--------------------------------------------------------------------------------------------------------------------------------------------------------
               Action                      Labor cost               Parts cost                 Cost per product              Cost on U.S. operators

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

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions specified in this AD.
    According to the manufacturer, some or all of the costs of this 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

    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.
