14 CFR Part 39

[Docket No. FAA-2020-0105; Product Identifier 2019-NM-172-AD; Amendment 
39-19851; AD 2020-04-12]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding Airworthiness Directives (ADs) 2012-22-
05 and 2018-19-03, which applied to certain Fokker Services B.V. Model 
F28 Mark 0070 and 0100 airplanes. AD 2012-22-05 required inspecting for 
cracks of the pistons on the main landing gear (MLG), and replacing the 
affected pistons if necessary. AD 2012-22-05 also required modifying 
the MLG, and revising the airplane maintenance program. AD 2018-19-03 
required an inspection of the MLG, and replacement if necessary. This 
AD retains the requirements of AD 2012-22-05, expands the 
applicability, and requires a new modification or replacement of the 
MLG; as specified in a European Union Aviation Safety Agency (EASA) AD, 
which is incorporated by reference. This AD was prompted by a 
determination that the required heat treatment may not have been 
applied to certain MLG pistons. The FAA is issuing this AD to address 
the unsafe condition on these products.

DATES: This AD becomes effective March 24, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 24, 
2020.
    The FAA must receive comments on this AD by April 23, 2020.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued AD 2012-22-05, Amendment 39-17241 (77 FR 68052, 
November 15, 2012) (``AD 2012-22-05''), and AD 2018-19-03, Amendment 
39-19403 (83 FR 46859, September 17, 2018) (``AD 2018-19-03''), which 
applied to certain Fokker Services B.V. Model F28 Mark 0070 and 0100 
airplanes. AD 2012-22-05 required inspecting for cracks of the pistons 
on the MLG, and replacing the affected pistons if necessary. AD 2012-
22-05 also required modifying the MLG, and revising the airplane 
maintenance program. AD 2018-19-03 required an inspection of the MLG, 
and replacement if necessary. The FAA issued these ADs to address MLG 
failure during the landing roll-out, which could result in damage to 
the airplane and injury to occupants.

Actions Since ADs 2012-22-05 and 2018-19-03 Were Issued

    Since ADs 2012-22-05 and 2018-19-03 were issued, the FAA has 
received a report of a crack found in the lower portion of a left-hand 
MLG piston; one possible factor was hydrogen-assisted cracking. The FAA 
determined that the cracked piston was part of a batch of six MLG 
pistons on which the required heat treatments may not have been applied 
during overhaul. Another possible contributing factor is that the wire 
harness port of the MLG piston is a highly stressed area, prone to 
high-rate crack growth if small surface imperfections are present.
    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0224, dated September 6, 2019 
(``EASA AD 2019-0224'') (also referred to 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. EASA AD 2019-0224 supersedes EASA ADs 2011-0159 and 2017-
0163 (which correspond to FAA ADs 2012-22-05 and 2018-19-03).
    This AD was prompted by a report of a crack found in the lower 
portion of a left-hand MLG piston, and a determination that the 
required heat treatment may not have been applied to certain MLG 
pistons. See the MCAI for additional background information.

[[Page 13476]]

Explanation of Retained Requirements

    Although this AD does not explicitly restate the requirements of AD 
2012-22-05 this AD retains all of the requirements of AD 2012-22-05. 
Those requirements are referenced in EASA AD 2019-0224, which, in turn, 
is referenced in paragraph (g) of this AD. This AD retains none of the 
requirements of AD 2018-19-03.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0224 describes procedures for repetitive inspections 
of the MLG pistons for cracks, replacing cracked MLG pistons, and 
modifying the MLG by replacing each affected part (MLG piston or MLG 
unit) with a serviceable part or replacing each affected MLG unit with 
a serviceable unit.
    This material 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 a bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this AD because the agency 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2019-0224 described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2019-0224 
is incorporated by reference in this AD. This AD, therefore, requires 
compliance with EASA AD 2019-0224 in its entirety, through that 
incorporation, except for any differences identified as exceptions in 
the regulatory text of this AD. Using common terms that are the same as 
the heading of a particular section in the EASA AD does not mean that 
operators need comply only with that section. For example, where the AD 
requirement refers to ``all required actions and compliance times,'' 
compliance with this AD requirement is not limited to the section 
titled ``Required Action(s) and Compliance Time(s)'' in the EASA AD. 
Service information specified in EASA AD 2019-0224 that is required for 
compliance with EASA AD 2019-0224 will be available on the internet at 
<a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. 
FAA-2020-0105 after the FAA final rule is published.

FAA's Justification and Determination of the Effective Date

    Since there are currently no domestic operators of these products, 
notice and opportunity for public comment before issuing this AD are 
unnecessary. In addition, for the reasons stated above, the FAA finds 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not precede it by notice and opportunity for 
public comment. The FAA invites you to send any written relevant data, 
views, or arguments about this AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2020-0105; 
Product Identifier 2019-NM-172-AD'' at the beginning of your comments. 
The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. The FAA will 
consider all comments received by the closing date and may amend this 
AD based on those comments.
    The FAA will post all comments received, without change, to <a href="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you provide. 
The FAA will also post a report summarizing each substantive verbal 
contact received about this AD.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, the FAA provide the following cost estimates to comply with 
this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2012-22-05...........  24 work-hours x $85 per hour =                $0          $2,040
                                                 $2,040.
New actions...................................  24 work-hours x $85 per hour =                 0           2,040
                                                 $2,040.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable the 
agency to provide cost estimates for the on-condition actions specified 
in this AD.

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.

Regulatory Findings

    The FAA has determined that 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

[[Page 13477]]

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.
