Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD 
was prompted by reports of cracks on certain nose landing gear (NLG) 
turning tubes resulting from incorrectly applied repairs. This AD 
requires removing the affected parts and replacing them with 
serviceable parts. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective October 21, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 21, 
2019.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Fokker Services 
B.V. Model F28 Mark 0070 and 0100 airplanes. The NPRM published in the 
Federal Register on May 14, 2019 (84 FR 21270). The NPRM was prompted 
by reports of cracks on certain NLG turning tubes resulting from 
incorrectly applied repairs. The NPRM proposed to require removing the 
affected parts and replacing them with serviceable parts.
    The FAA is issuing this AD to address cracking of NLG turning 
tubes, which could lead to NLG turning tube failure, possibly resulting 
in damage to the airplane and injury to occupants.
    The European Union 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

[[Page 48564]]

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 http://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0324.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA 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. The FAA has 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.

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.
    The FAA is 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
