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 2018-0076, dated April 6, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Fokker Services B.V. Model F28 airplanes. The MCAI states: With [Fokker Service Bulletins] SBF100-32-095 and SBF28-32-154, Fokker Services introduced the option of installing a T-union with an integral filter into the landing gear hydraulic control system. On some F28 Mark 0070 and Mark 0100 aeroplanes, the affected part was installed on the production line. Since introduction, occurrences were reported where the T-union filter disconnected from its housing, and in some cases migrated. In one occurrence, the migrated filter caused a flow reduction and inability to retract one of the main landing gear (MLG) legs. This condition, if not corrected, could lead to flow reduction along the hydraulic circuit and inability to completely extend one of the MLG legs, possibly resulting in damage to the aeroplane during landing, and consequent injury to occupants. To address this potential unsafe condition, Fokker Services issued the applicable SB [Fokker Service Bulletin SBF28-32-166; and Fokker Service Bulletin SBF100-32-170] to provide instructions to replace the affected parts with improved parts. Fokker Services also cancelled the SBs that introduced the affected parts. For the reason described above, this [EASA] AD requires replacement of the affected parts with T-unions without an integral filter. This [EASA] AD also prohibits the installation of affected parts. 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- 0707. Related Service Information Under 1 CFR Part 51 Fokker Services B.V. has issued Service Bulletin SBF28-32-166, dated February 21, 2018; and Service Bulletin SBF100-32-170, dated February 21, 2018. This service information describes procedures for removal of certain T-unions with an integral filter and installation of T-unions without an integral filter. These documents are distinct since they apply to different airplane models in different configurations. 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: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 10 work-hours x $85 per hour = $850.......................... $1,038 $1,888 $7,552 ---------------------------------------------------------------------------------------------------------------- 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 [[Page 39920]] 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.
