SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Embraer S.A. Model 
ERJ 190-100 STD, -100 LR, -100 ECJ, and -100 IGW airplanes; and Model 
ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. The NPRM published in 
the Federal Register on June 11, 2018 (83 FR 26877). The NPRM was 
prompted by reports of bushing migration and loss of nut torque on the 
engine pylon lower inboard and outboard link fittings. The NPRM 
proposed to require modification of the attaching parts of the LH and 
RH pylon lower link fittings, inboard and outboard positions. The NPRM 
also specified that accomplishing certain proposed actions would 
terminate certain requirements in AD 2014-16-16, Amendment 39-17940 (79 
FR 48018, August 15, 2014).
    We are issuing this AD to address loss of integrity of the engine 
pylon lower link fittings, possibly resulting in separation of the 
engine from the wing.
    Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which 
is the aviation authority for Brazil, has issued Brazilian AD 2017-04-
01, effective April 25, 2017 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Embraer S.A. Model ERJ 190-100 STD, -100 
LR, -100 ECJ, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 
LR, and -200 IGW airplanes. The MCAI states:

    This [Brazilian] AD was prompted by reports of bushing migration 
and loss of nut torque on the engine pylon lower inboard and 
outboard link fittings. We are issuing this [Brazilian] AD to 
prevent loss of integrity of the engine pylon lower link fittings, 
which could result in separation of the engine from the wing.
    This [Brazilian] AD requires modifications of the attaching 
parts of the left handle (LH) and right handle (RH) pylon lower link 
fittings, inboard and outboard positions.

0509.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comment received. The Air Line 
Pilots Association, International (ALPA) stated that it supported the 
intent of the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule as proposed, except for minor editorial changes. We 
have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Embraer S.A. has issued Embraer Service Bulletin 190-54-0016, 
Revision 04, dated December 7, 2017; and Embraer Service Bulletin 
190LIN-54-0008, Revision 02, dated May 9, 2018. The service information 
describes procedures for modification of the attaching parts of the LH 
and RH pylon lower link fittings, inboard and outboard positions. These 
documents are distinct since they apply to different airplane models. 
This service information 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

    We estimate that this AD affects 85 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
          Action                Labor cost      Parts cost       Cost per product        Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Modification..............  Up to 270 work-         $3,200  Up to $26,150............  Up to $2,222,750.
                             hours x $85 per
                             hour = $22,950.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
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.
    We are 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

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) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

    (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
