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 0100 airplanes. The NPRM published in the Federal 
Register on November 6, 2017 (82 FR 51364) (``the NPRM''). The NPRM was 
prompted by a report that a jammed control cable prevented the full 
extension of the nose LG. The NPRM proposed to require a general visual 
inspection of the LG handle teleflex cable conduit connector for the 
presence of a grease nipple, a maintenance records check of affected 
airplanes, and if necessary, a detailed inspection for corrosion and 
damage of the LG handle teleflex cable, replacement if found, and 
lubrication. It also proposed to require revising the maintenance or 
inspection program, as applicable. We are issuing this AD to detect and 
correct erratic or hard-to-move LG handles, which could lead to the 
nose LG not being in the fully extended position during landing and 
consequent damage to the airplane and injury to the flight crew and 
passengers.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0068, dated April 24, 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 0100 airplanes. The MCAI states:

    A report was received of an alledgedly post-SBF100-32-107 
(introducing a teleflex cable conduit with a grease nipple and a 
stainless steel teleflex cable) Fokker 100 aeroplane landing with a 
nose landing gear (LG) that was not completely in the extended 
position, in spite of the application by the crew of the relevant 
normal and abnormal Airplane Flight Manual LG extension procedures. 
The investigation revealed that the failure of the nose LG to 
completely extend had been caused by a jammed teleflex cable of the 
LG control system, which resulted in a hydraulic lock in the nose LG 
extension/retraction actuator. The investigation also revealed that 
the teleflex cable conduit connector on the subject aeroplane did 
not have the grease nipple installed, so that the aeroplane was 
actually not in the full post-SBF100-32-107 configuration.
    Based on an incorrect assumption with regard to full 
incorporation of SBF100-32-107 (i.e. the presence of the grease 
nipple on the conduit connector), Maintenance Review Board (MRB) 
task 323100-00-04 (removal, inspection, greasing and reinstallation 
of teleflex cable), which is only applicable for aeroplanes without 
the grease nipple, had been removed from the scheduled maintenance 
programme for the aeroplane. As a result, no detailed inspection or 
greasing of the teleflex cable had been accomplished on the 
aeroplane during the last 24,000 flight cycles (FC) or 17 years, 
leading to a lack of lubricant and excessive wear of the cable. 
Analysis indicates the possibility of more aeroplanes that do not 
have the grease nipple on the conduit connector, and where MRB task 
323100-00-04 has been inadvertently removed from the scheduled 
maintenance program.
    This condition, if not detected and corrected, could lead to 
further landings with the nose LG not in the fully extended 
position, possibly resulting in damage to the aeroplane and injury 
to occupants.
    To address this potential unsafe condition, Fokker Services 
published SBF100-32-167 (hereafter referred to as `the SB' in this 
[EASA] AD) to provide inspection instructions.
    For the reasons described above, this [EASA] AD requires a one-
time [general visual] inspection of the LG handle teleflex cable 
conduit connector for the presence of the grease nipple and, 
depending on findings, [a maintenance records check and] 
accomplishment of applicable corrective action(s). This [EASA] AD 
also requires the reporting of findings to Fokker Services, and to 
ensure that the maintenance [or inspection] programme [as 
applicable] contains those instructions applicable to the aeroplane 
configuration.

    Required actions also include a detailed inspection for corrosion 
and damage of the LG handle teleflex cable, replacement of the LG 
handle teleflex cable if necessary, and lubrication of the LG handle 
teleflex cable. 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-2017-1021.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We considered the comment received. The commenter, 
Peter North, supported the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD 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 correcting 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 Fokker Service Bulletin SBF100-32-
167, dated December 14, 2016. This service information describes 
procedures for a one-time inspection of the nose LG control cable; a

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 to 
the Director of the System Oversight Division.

Regulatory Findings

    We determined that 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.
