Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0037, dated February 19, 2019 (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 Mark 0070 and 0100 airplanes. The MCAI states: Comments Invited Occurrences have been reported of finding cracks on certain NLG turning tubes. The subsequent investigation results revealed that the cracks initiated from an area that is sensitive to fatigue cracking, which had been subject to incorrectly applied repairs. This condition, if not detected and corrected, could lead to NLG turning tube failure, possibly resulting in damage to the aeroplane and injury to occupants. To address this potential unsafe condition, Fokker Services published the SB [service bulletin] to provide replacement instructions, referring to SLS [Safran Landing Systems] SB F100–32–117 for in-shop inspection. For the reasons described above, this [EASA] AD requires removal from service of the affected part and replacement with a serviceable part.

Send your comments to You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for 21271 and locating Docket No. FAA–2019– 0324. Related Service Information Under 1 CFR Part 51 Fokker Services B.V. has issued Fokker Service Bulletin SBF100–32– 171, dated November 27, 2018. This service information describes procedures for removing and replacing affected NLG turning tubes. Safran has issued Service Bulletin F100–32–117, dated July 30, 2018. This service information describes procedures for a magnetic particle or eddy current inspection of NLG turning tubes. 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: khammond on DSKBBV9HB2PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 9 work-hours × $85 per hour = $765 .......................................................................................... $1,282 $2,047 $8,188 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 VerDate Sep<11>2014 16:21 May 13, 2019 Jkt 247001 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 PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 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 E:\FR\FM\14MYP1.SGM 14MYP1 21272 Federal Register / Vol. 84, No. 93 / Tuesday, May 14, 2019 / Proposed Rules 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 and associated appliances 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2019-0037, dated February 19, 2019 (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 Mark 
0070 and 0100 airplanes. The MCAI states:

    Occurrences have been reported of finding cracks on certain NLG 
turning tubes. The subsequent investigation results revealed that 
the cracks initiated from an area that is sensitive to fatigue 
cracking, which had been subject to incorrectly applied repairs.
    This condition, if not detected and corrected, could lead to NLG 
turning tube failure, possibly resulting in damage to the aeroplane 
and injury to occupants.
    To address this potential unsafe condition, Fokker Services 
published the SB [service bulletin] to provide replacement 
instructions, referring to SLS [Safran Landing Systems] SB F100-32-
117 for in-shop inspection.
    For the reasons described above, this [EASA] AD requires removal 
from service of the affected part and replacement with a serviceable 
part.

    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-2019-
0324.

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 and associated appliances 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.
