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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.
