Airworthiness Directives; Embraer S.A. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW airplanes; and
Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. This AD was
prompted by reports of corrosion and chromium layer chipping of the
forward and aft pintle pins of the main landing gear (MLG) shock
struts. This AD requires repetitive inspections for discrepancies of
affected forward and aft pintle pins of the MLG shock struts, and
corrective actions if necessary. We are issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective April 2, 2019.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of April 2,
2019.

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 all Embraer S.A. Model ERJ
190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW
airplanes. The NPRM published in the Federal Register on November 5,
2018 (83 FR 55297). The NPRM was prompted by reports of corrosion and
chromium layer chipping of the forward and aft pintle pins of the MLG
shock struts. The NPRM proposed to require repetitive inspections for
discrepancies of affected forward and aft pintle pins of the MLG
[[Page 6065]]
shock struts, and corrective actions if necessary. We are issuing this
AD to address discrepancies of affected forward and aft pintle pins of
the MLG shock struts, which could result in the pintle pin shearing
under normal load and consequent collapse of the MLG during takeoff or
landing.
Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which
is the aviation authority for Brazil, has issued Brazilian
Airworthiness Directive 2018-07-01, effective July 24, 2018 (referred
to after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Embraer S.A.
Model ERJ 190-100 STD, -100 LR, -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 corrosion and
chromium layer chipping on the rearward and forward Pintle Pin of
the Main Landing Gear (MLG) Shock Struts. We are issuing this
[Brazilian] AD to detect and correct Pintle Pin[s] having
[discrepancies including] corrosion or chromium layer chipping,
which could cause the Pintle Pin[s] to shear under normal load and
lead to collapse of the MLG during take-off or landing.
Corrective actions include repair or replacement of affected
forward and aft pintle pins of the left- and right-hand MLG shock
struts. You may examine the MCAI in the AD docket on the internet at
http://www.regulations.gov by searching for and locating Docket No.
FAA-2018-0905.
Comments
We gave the public the opportunity to participate in developing
this final rule. We received no comments on the NPRM or on the
determination of the cost to the public.
Change Made to This Final Rule
We have changed this final rule to reference Task 32-11-001-1034,
``Main Landing Gear Shock Strut Pintle Pins--Internal,'' of the Embraer
190/195 Maintenance Review Board Report MRB-1928, Revision 12, dated
September 27, 2018. In Revision 12, among other changes, the task
interval is extended from 66 months to 72 months resulting from
findings of an MLG sampling program.
We have also added Embraer 190/195 Maintenance Review Board Report
MRB-1928, Revision 12, dated September 27, 2018, to paragraphs (i)(1)
and (i)(2) of this AD to give credit for inspections that have been
done before the effective date of this AD as specified in Task 57-50-
007-1247, ``Main Landing Gear Trunnion Fittings--Inside Surfaces--
Internal,'' and Task 32-11-00-001, ``Main Landing Gear (MLG)'' of
Embraer 190/195 Maintenance Review Board Report MRB-1928, Revision 12,
dated September 27, 2018.
We have also revised paragraph (i)(3) of this AD to refer to Task
32-11-001-1034, ``Main Landing Gear Shock Strut Pintle Pins--
Internal,'' Embraer 190/195 Maintenance Review Board Report MRB-1928,
Revision 11, dated May 10, 2017, and we have redesignated subsequent
paragraphs.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this final rule with the changes
described previously and 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.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

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.
