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.

Related Service Information Under 1 CFR Part 51

    Embraer has issued Service Bulletin 190-32-0065, Revision 02, dated

Costs of Compliance

    We estimate that this AD affects 96 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per product         Cost on U.S. operators

Up to 22 work-hours x $85 per hour = Up               $0  Up to $1,870 per            Up to $179,520 per
 to $1,870.                                                inspection cycle.           inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of any required 
inspection. We have no way of determining the number of aircraft that 
might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost                 Parts cost       Cost per product
------------------------------------------------------------------------
6 work-hours x $85 per hour =     $1,750 per MLG....  $2,260 per MLG
 $510 per MLG (replacement).
6 work-hours x $85 per hour =     $0................  $510 per MLG.
 $510 per MLG (repair).

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.
