Unsafe Condition
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 could create an ignition source in the main tank vapor space, possibly resulting in a fuel tank explosion and consequent loss of the airplane.

Federal Register Abstract
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.

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 <a href="http://www.regulations.gov">http://www.regulations.gov</a> 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:
<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.

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.
[[Page 51316]]
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.
