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 April 27, 2018 (83 FR 18488). The NPRM was prompted by a report that the retraction actuator eye-end of a Goodrich MLG failed. The NPRM proposed to require a one-time general visual inspection of the LH and RH MLG retraction actuators and replacement if necessary. We are issuing this AD to address failure of the retraction actuator eye-end of a Goodrich MLG, which could prevent retraction of the MLG and/or its complete 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 AD 2018-0001, dated January 4, 2018 (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, following take-off after gear up selection, the retraction actuator eye-end (P/N [part number] 41518-3) of a Goodrich MLG failed. After the LG UNSAFE indication, the flight crew successfully selected gear down and locked by applying the alternate extension [[Page 40960]] procedure, and an uneventful landing was made. Investigation results showed that the final overload fracture of the eye-end was preceded by fatigue cracks, believed to have been caused by interference between the MLG retraction actuator eye-end and the actuator bracket. It was also highlighted that the affected eye-end had been installed incorrectly, i.e. with the grease nipple located on the lower side, thus causing damage to the eye-end due to interference with the bracket. Further investigations revealed other occurrences of interference between retraction actuator eye-end and bracket with resulting damage. This condition, if not detected and corrected, could prevent retraction of the MLG and/or its complete extension, possibly resulting in damage to the aeroplane during landing, and consequent injury to occupants. To address this potential unsafe condition, Fokker Services published SBF100-32-168 to provide inspection and replacement instructions. For the reasons described above, this AD requires a one-time [general visual] inspection [for deficiencies] (check the eye-end for presence of interference/damage and for orientation of the greasing nipple) of the MLG retraction actuators, left-hand (LH) and right-hand (RH) sides, and, depending on findings, replacement. 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- 0303. 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 Fokker Service Bulletin SBF100-32- 168, dated May 22, 2017. This service information describes procedures for a one-time general visual inspection for deficiencies of the Goodrich MLG retraction actuators and replacement of the actuator if necessary (e.g., if the retraction actuator greasing nipple is not located on the upper side MLG retraction actuator eye-end or if interference damage or evidence of removed damage is present on the eye-end of the MLG retraction actuator). 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: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection............ 1 work-hour x $85 per hour $0 $85 per inspection $425 per inspection = $85 per inspection cycle. cycle. cycle. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement................................ 1 work-hour x $85 per hour = $85... $0 $85 ---------------------------------------------------------------------------------------------------------------- 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 [[Page 40961]] under the criteria of the Regulatory Flexibility Act.
