SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Fokker Services
B.V. Model F28 airplanes. The NPRM published in the Federal Register on
June 1, 2016 (81 FR 34929) (``the NPRM''). The NPRM was prompted by
reports indicating that the MLG could not be extended and locked down
during approach. The NPRM proposed to require a detailed inspection of
the restrictor check valve filter screens to detect any degraded or
failed filter screens, and installation of serviceable parts. We are
issuing this AD to detect and correct any degraded or failed filter
screens. This condition, if not corrected, could prevent MLG extension
and lock-down and result in an emergency landing with consequent injury
to occupants and damage to the airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2015-0077, dated May 6, 2015 (referred to after
this as the Mandatory Continuing Airworthiness Information, or ``the
MCAI''), to correct an unsafe condition for certain Fokker Services
B.V. Model F28 airplanes. The MCAI states:
Two occurrences were reported concerning two different
aeroplanes, where during approach, after selecting landing gear
down, one of the main landing gears (MLG) could not be extended and
locked down. In both cases, subsequent investigation revealed that
the filter screen of the corresponding restrictor check valve
(integrated in a hydraulic hose assembly) was broken, and debris
inside the restrictor check valve was blocking the return flow from
the affected MLG actuator. Additional inspection of the fleet of the
operator involved revealed more damaged or failed filter screens.
This condition, if not detected and corrected, could prevent MLG
extension and lock-down, possibly resulting in an emergency landing
with consequent damage to the aeroplane and injury to occupants.
To address this unsafe condition, Fokker Services published
SBF28-32-164 and SBF100-32-166 to provide instructions for removal
of the affected hydraulic hoses (including the restrictor check
valve) to be inspected in-shop, and for installation of serviceable
parts. Fokker Services also published Component SB CSB-32-026 to
provide those in-shop inspection instructions to detect any damaged
filter screen.
For the reasons described above, this [EASA] AD requires a
onetime removal of the landing gear hydraulic hoses for the purpose
of an in-shop inspection of the affected restrictor check valves
filter screens and, depending on findings, re-installation, or
replacement of the affected hose(s) with a serviceable part.
This [EASA] AD is considered to be an interim action to detect
any degraded or failed filter screens and remove them from service
and to collect additional data; further [EASA] AD action may follow.
More information on this subject can be found in Fokker Services All
Operators Messages AOF28.041 and AOF100.189#02.

6895.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed, except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Fokker Services B.V. has issued the following service information,
which describes procedures for the replacement of hydraulic hose
assemblies. These service bulletins are distinct because they apply to
different airplane models.
<bullet> Fokker Service Bulletin SBF28-32-164, dated January 14,
2015.
<bullet> Fokker Service Bulletin SBF100-32-166, dated January 14,
2015.
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.

Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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.
Regulatory Findings
We 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 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. 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.
