gear (NLG) turning tubes resulting from incorrectly applied repairs.
This proposed AD would require removing the affected parts and
replacing them with serviceable parts. We are proposing this AD to
address the unsafe condition on these products.

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 http://www.regulations.gov by searching for 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:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
9 work-hours x $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 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
[[Page 21272]]
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.
List of Subjects in 14 CFR Part 39

reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
Fokker Services B.V.: Docket No. FAA-2019-0324; Product Identifier

gear.
(e) Reason
This AD was prompted by reports of cracks on certain nose
landing gear (NLG) turning tubes resulting from incorrectly applied
repairs. We are 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Definitions
(1) An affected part is an NLG turning tube assembly having part
number (P/N) 201456200, 201071202, 201071240, or 201071241;
installed on an NLG unit having a P/N identified in Safran Service
Bulletin F100-32-117, dated July 30, 2018.
(2) A serviceable part is an affected part that is new or that,
before installation, has passed an inspection (no cracks found,
having the correct radius) in accordance with the Accomplishment
Instructions of Safran Service Bulletin F100-32-117, dated July 30,
2018.
(h) Replacement
Within 22,000 flight cycles after the effective date of this AD:
Replace the affected parts, with serviceable parts, in accordance

any airplane, an affected part, unless it is a serviceable part.
(j) No Reporting Requirement
Although Safran Service Bulletin F100-32-117, dated July 30,
2018, specifies to submit certain information to the manufacturer,
this AD does not include that requirement.

International Section, Transport Standards Branch, FAA, has the
authority to approve AMOCs for this AD, if requested using the

send your request to your principal inspector or local Flight
Standards District Office, as appropriate. If sending information
directly to the International Section, send it to the attention of
the person identified in paragraph (l)(2) of this AD. Information
may be emailed to: [email protected]. Before using any
approved AMOC, notify your appropriate principal inspector, or
lacking a principal inspector, the manager of the local flight
standards district office/certificate holding district office.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain corrective actions from a manufacturer, the action must be
accomplished using a method approved by the Manager, International
Section, Transport Standards Branch, FAA; or the European Aviation
Safety Agency (EASA); or Fokker Services B.V.'s EASA Design
Organization Approval (DOA). If approved by the DOA, the approval
must include the DOA-authorized signature.
