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 Fokker Services 
B.V. Model F28 Mark 0070 and 0100 airplanes. The NPRM published in the 
Federal Register on May 25, 2018 (83 FR 24233). The NPRM was prompted 
by a report of cracks, in various directions, in the lower portion of a 
MLG piston. The NPRM proposed to require a detailed visual inspection 
of the MLG, and replacement if necessary.
    We are issuing this AD to address cracks in the lower portion of 
the MLG, which could lead to MLG failure during the landing roll-out, 
and possibly result in damage to the airplane and injury to occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0163, dated September 4, 2017; corrected September 5, 2017 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. 
The MCAI states:

    An occurrence was reported where, during a walk around check, a 
number of cracks, in various directions, were discovered in the 
lower portion of a MLG piston, Part Number (P/N) 41141-5. No 
technical investigation results are available as yet, but based on a 
previous event, as a result of which EASA issued AD 2009-0221R1, 
later superseded by [EASA] AD 2011-0159, stress corrosion is 
suspected to have caused these cracks.
    This condition, if not detected and corrected, could lead to MLG 
failure during the landing roll-out, possibly resulting in damage to 
the aeroplane and injury to occupants.
    To address this potential unsafe condition, Fokker Services 
published Service Bulletin (SB) SBF100-32-169 to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires a one-
time detailed visual inspection (DVI) of the MLG pistons for cracks 
and, depending on findings, replacement.
    This [EASA] AD also requires the reporting of inspection results 
to Fokker Services.
    This [EASA] AD has been republished to correct wrong P/N 
references in paragraphs (1) and (4).
    This [EASA] AD is considered an interim measure and further 
[EASA] AD action may follow.

    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-
0448.

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.

Conclusion

    We reviewed the relevant data 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued Fokker Service Bulletin SBF100-32-
169, dated August 23, 2017. The service information describes 
procedures for a detailed visual inspection of the MLG, and replacement 
if necessary. 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 5 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

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

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.
