14 CFR Part 39

[Docket No. FAA-2013-0630; Directorate Identifier 2012-NM-213-AD;

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 0070 and 0100 airplanes. This AD 
was prompted by a design review, which revealed that, under certain 
failure conditions, wiring in the main fuel tank could develop a short 
circuit that might cause a hot spot on the wiring conduit or puncture 
the wiring conduit wall. This AD requires installing fuses in the power 
supply wiring and/or return wiring for various components in the fuel 
system; and revising the airplane maintenance program by incorporating 
critical design configuration control limitations. 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 becomes effective December 20, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 20, 
2013.

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 the specified products. The 
NPRM published in the Federal Register on July 31, 2013 (78 FR 46303). 
The NPRM proposed to correct an unsafe condition for the specified 
products.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0241, dated November 12, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Prompted by an accident * * *, the 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 design review conducted by Fokker Services on the Fokker 70 
and Fokker 100 in response to these regulations revealed that under 
certain failure conditions of the wiring of the Overflow Valve Reed 
Switch, or the solenoid of the Level Control Pilot Valve (LCPV), or 
the solenoid of the Re/De-fueling Shut- Off Valve, or the Collector-
Tank Low Level Float-Switch, a short circuit may develop that causes 
a hot spot on the wiring conduit, or puncturing of the wiring 
conduit wall in the main fuel tank.
    This condition, if not corrected, could create an ignition 
source in the main fuel tank vapour space, possibly resulting in a 
fuel tank explosion and consequent loss of the aeroplane.
    For the reasons described above, this [EASA]AD requires the 
installation of fuses in the power supply wiring and/or return 
wiring for the main tank overflow valve reed-switches, the LCPV 
solenoid, the Re/De-fuel shut-off valve solenoid and the collector-
tank Low Level float switch and subsequently, the implementation of 
the associated Critical Design Configuration Control Limitations 
(CDCCL[s]) [and revising the maintenance program to incorporate the 
CDCCLs].

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0630-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 46303, July 31, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available 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 (78 FR 46303, July 31, 2013) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 46303, July 31, 2013).

Costs of Compliance

    We estimate that this AD affects 10 airplanes of U.S. registry.
    We estimate the following costs to comply with 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.
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0630-0002; or in
