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.
ADDRESSES: You may examine the AD on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2013-0630; or in person at the U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

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 EASAAD 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 (CDCCLs) 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:
Are consistent with the intent that was proposed in the NPRM (78 FR 46303, July 31, 2013) for correcting the unsafe condition; and
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:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Installation and revision of 29 work-hours x $85 per $4,600 $7,065 $70,650
maintenance program. hour = $2,465.
----------------------------------------------------------------------------------------------------------------
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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
-
Will not affect intrastate aviation in Alaska; and
-
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.
