14 CFR Part 39

[Docket No. FAA-2015-8472; Directorate Identifier 2014-NM-106-AD; 
Amendment 39-18603; AD 2016-16-05]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Fokker Services B.V. Model F.28 Mark 1000, 2000, 3000, and 4000 
airplanes. This AD was prompted by a design review that revealed a hot 
spot may develop in the main fuel tank under certain failure conditions 
of the solenoid of the level control pilot valve, the reed switch of 
the main tank overflow valve, the level float switch of the collector 
tank, or the solenoid of the main tank fueling shut-off valve. This AD 
requires installing fuses in the wiring of the solenoid of the level 
control pilot valve, the reed switch of the main tank overflow valve, 
the level float switch of the collector tank, and the solenoid of the 
main tank fueling shut-off valve, as applicable. This AD also requires 
accomplishing concurrent actions and revising the airplane maintenance 
or inspection program, as applicable, by incorporating fuel 
airworthiness limitation items and critical design configuration 
control limitations (CDCCLs). We are issuing this AD to prevent an 
ignition source in the main fuel tank vapor space, which could result 
in a fuel tank explosion and consequent loss of the airplane.

DATES: This AD is effective September 8, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 8, 
2016.

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 all Fokker Services B.V. 
Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. The NPRM 
published in the Federal Register on January 20, 2016 (81 FR 3042) 
(``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0107, dated May 7, 2014 (referred to after 
this the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition for all Fokker Services B.V. 
Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. The MCAI states:

    Prompted by an accident * * *, the Federal Aviation 
Administration (FAA) published Special Federal Aviation Regulation 
(SFAR) 88 [(66 FR 23086, May 7, 2001)], and the Joint Aviation 
Authorities (JAA) published Interim Policy INT/POL/25/12.
    The review conducted by Fokker Services on the Fokker F28 design 
in response to these regulations revealed that, under certain 
failure conditions of the solenoid of the level control pilot valve, 
the main tank overflow valve reed switch, the collector tank level 
float switch or the main tank fuelling shut-off valve solenoid, a 
hot spot may develop in the tank.
    This condition, if not corrected, could create an ignition 
source in the main tank vapour space, possibly resulting in a fuel 
tank explosion and consequent loss of the aeroplane.
    To address this potential unsafe condition, Fokker Services 
developed a modification to the wiring (installation of fuses) of 
the affected components.
    For the reasons described above, this [EASA] AD requires the 
installation of fuses in the wiring of the affected components [the 
solenoid of the level control pilot valve, the reed switch of the 
main tank overflow valve, the level float switch of the collector 
tank, and the solenoid of the main tank fuelling shut-off valve] 
and, subsequently, the implementation of the associated Critical 
Design Configuration Control Limitations (CDCCL) items [and revision 
of the maintenance or inspection program].
    More information on this subject can be found in Fokker Services 
All Operators Message AOF28.038#02.

    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-2015-
8472.

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.

Explanation of Changes Made to This AD

    We revised certain document citations throughout this AD to meet 
the Office of the Federal Register's requirements for materials 
incorporated by reference. These changes are for formatting purposes 
and do not affect the requirements of this AD.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the changes described 
previously and 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.

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.
