14 CFR Part 39

[Docket No. FAA-2018-0767; Product Identifier 2018-NM-068-AD; Amendment 
39-19514; AD 2018-25-03]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD 
was prompted by reports that debris from the parking brake shut off 
valve (PBSOV) could create a partial blockage of the restrictor check 
valve in the hydraulic return line of the PBSOV. This AD requires 
replacing the restrictor check valve with an improved valve that has a 
filter screen. We are issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective January 14, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 14, 
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 Fokker Services B.V. 
Model F28 Mark 0070 and 0100 airplanes. The NPRM published in the 
Federal Register on September 7, 2018 (83 FR 45362). The NPRM was 
prompted by reports that debris from the PBSOV could create a partial 
blockage of the restrictor check valve in the hydraulic return line of 
the PBSOV. The NPRM proposed to require replacing the restrictor check 
valve with an improved valve that has a filter screen.
    We are issuing this AD to address debris from the PBSOV that could 
create a partial blockage of the restrictor check valve in the 
hydraulic return line of the PBSOV, which, if not corrected, may 
prevent complete main landing gear extension, possibly resulting in 
damage to the airplane during landing, and consequent 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 
Airworthiness Directive 2018-0077 dated April 6, 2018 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for Fokker Services B.V. 
Model F28 Mark 0070 and 0100 airplanes. The MCAI states:

    Service experience with Fokker 70 and Fokker 100 aeroplanes has 
shown that debris from the parking brake shut-off valve (PBSOV) can 
eventually block the restrictor check valve in the hydraulic return 
line of the PBSOV. Prompted by these findings, Fokker Services 
issued [Service Bulletin] SBF100-32-159 to introduce a new PBSOV and 
a one-time inspection for debris in the affected part of the 
hydraulic return system. EASA issued AD 2009-0220 [which corresponds 
to FAA AD 2010-22-05 (75 FR 66649, October 29, 2010) (``AD 2010-22-
05'')] to require those actions. In addition, Fokker Services issued 
SBF100-32-163 to introduce the option to install a restrictor check 
valve with a filter screen in the return line of the PBSOV. A recent 
review of in-service experience and the SBF100-32-159 inspection 
results revealed new occurrences of debris that obstructed (but did 
not completely block) the restrictor check valve.
    This condition, if not corrected, might prevent complete main 
landing gear extension, possibly resulting in damage to the 
aeroplane during landing, and consequent injury to occupants.
    To address this potential unsafe condition, Fokker Services 
issued Revision 1 of SBF100-32-163, providing instructions to 
replace the restrictor check valve with the improved valve 
incorporating a filter screen.
    For the reason described above, this [EASA] AD requires the 
replacement of the restrictor check valve in the return line of the 
PBSOV with the improved valve.

0767.

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:
     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

    Fokker Services B.V. has issued Service Bulletin SBF100-32-163, 
Revision 1, dated February 21, 2018. This service information describes 
procedures for removing the restrictor check valve in the hydraulic 
return line of the PBSOV and installing an improved restrictor check 
valve that has a filter screen. 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.

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.
