Discussion 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 F100/70] 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 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. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0767. Relationship Between Proposed AD and AD 2010–22–05 This NPRM does not propose to supersede AD 2010–22–05.

Related Service Information Under 1 CFR Part 51 FAA’s Determination Fokker Services B.V. has issued Fokker Service Bulletin F100/70 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 This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information and determined 45363 the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD affects 4 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: daltland on DSKBBV9HB2PROD with PROPOSALS ESTIMATED COSTS Labor cost Parts cost Cost per product Cost on U.S. operators 2 work-hours × $85 per hour = $170 .......................................................................................... $1,282 $1,452 $5,808 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 proposed 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 to the Director of the System Oversight Division. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on VerDate Sep<11>2014 19:16 Sep 06, 2018 Jkt 244001 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 this proposed regulation: 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.

Discussion

    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 F100/70] 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 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.

    You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0767.

Relationship Between Proposed AD and AD 2010-22-05

    This NPRM does not propose to supersede AD 2010-22-05. Rather, we 
have determined that a stand-alone AD would be more appropriate to 
address the changes in the MCAI. This proposed AD would require 
replacing the restrictor check valve with an improved valve that has a 
filter screen. Accomplishment of the proposed

[[Page 45363]]

actions would then terminate all requirements of AD 2010-22-05.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued Fokker Service Bulletin F100/70 
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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

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 proposed 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 to the Director of the System Oversight 
Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Fokker Services B.V.: Docket No. FAA-2018-0767; Product Identifier 
2018-NM-068-AD.

(a) Comments Due Date

    We must receive comments by October 22, 2018.

(b) Affected ADs

    This AD affects AD 2010-22-05, Amendment 39-16484 (75 FR 66649, 
October 29, 2010) (``AD 2010-22-05'').

(c) Applicability

    This AD applies to Fokker Services B.V. Model F28 Mark 0070 and 
0100 airplanes, certificated in any category, all serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by service experience showing 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. We are issuing this AD to address this condition, 
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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Definitions

    For the purposes of this AD, the definitions in paragraphs 
(g)(1) through (g)(3) apply.
    (1) An affected part is any hydraulic restrictor check valve 
having part number (P/N) D71293-003, P/N D71295-401, or P/N D71296-
401.
    (2) Group 1 airplanes are those that have an affected part 
installed.
    (3) Group 2 airplanes are those that do not have an affected 
part installed.

[[Page 45364]]

(h) Required Actions

    For Group 1 airplanes, within 24 months after the effective date 
of this AD, modify the airplane by replacing each affected part with 
a restrictor check valve that has a filter screen, P/N CKLX0517200B 
or P/N CKLX0520100B, as applicable, in accordance with the 
accomplishment instructions of Fokker Service Bulletin F100/70 
SBF100-32-163, Revision 1, dated February 21, 2018.

(i) Parts Installation Prohibition

    Do not install an affected part on any airplane, as required by 
paragraph (i)(1) or (i)(2) of this AD, as applicable.
    (1) For Group 1 airplanes: After modification of the airplane as 
required by paragraph (h) of this AD.
    (2) For Group 2 airplanes: From the effective date of this AD.

(j) Terminating Actions for AD 2010-22-05

    Accomplishing the actions required by paragraph (h) of this AD 
terminates all requirements of AD 2010-22-05.

(k) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information
