 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2017-1021; Product Identifier 2017-NM-052-AD]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This proposed AD was prompted by a report that a jammed control cable prevented the full extension of the nose landing gear (LG). This proposed AD would 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. This proposed AD would also require revising the maintenance or inspection program, as applicable. We are proposing this AD to address the unsafe condition on these products.
 DATES: We must receive comments on this proposed AD by December 21, 2017.
 ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: *Federal eRulemaking Portal:*

Discussion 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 any corrosion or damage is found, and lubrication of the LG handle teleflex cable.

                     section. FAA's Determination and Requirements of This Proposed AD 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 pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD affects 8 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs

 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 proposed AD is 2120-0056. The paperwork cost associated with this proposed 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 proposed 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 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.
