Federal Register Abstract
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 the absence of electrical insulation material between a wing or integral center wing tank (ICWT) fuel quantity indication system (FQIS) probe and the bottom of the tank structure. This AD requires for all airplanes, applying sealant below the FQIS probes in the wing tanks; and for certain airplanes, applying sealant below the FQIS probes in the ICWT. This AD also requires revising the aircraft maintenance program by revising the fuel airworthiness limitations and incorporating critical design configuration control limitations (CDCCLs). We are issuing this AD to prevent an ignition source in the 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 0070 and 0100 airplanes. This AD
was prompted by a design review which revealed the absence of
electrical insulation material between a wing or integral center wing
tank (ICWT) fuel quantity indication system (FQIS) probe and the bottom
of the tank structure. This AD requires for all airplanes, applying
sealant below the FQIS probes in the wing tanks; and for certain
airplanes, applying sealant below the FQIS probes in the ICWT. This AD
also requires revising the aircraft maintenance program by revising the
fuel airworthiness limitations and incorporating critical design
configuration control limitations (CDCCLs). We are issuing this AD to
prevent an ignition source in the tank vapor space, which could result
in a fuel tank explosion and consequent loss of the airplane.
DATES: This AD becomes effective July 30, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of July 30,
2012.
ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on March 27, 2012 (77
FR 18141). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
[T]he FAA published Special Federal Aviation Regulation (SFAR)
88, 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 the absence of electrical insulation material between
a wing or Integral Center Wing Tank (ICWT) Fuel Quantity Indication
System (FQIS) probe and the bottom of the tank structure could,
under certain conditions, result in an ignition source in the tank
vapour space.
This condition, if not corrected, could result in a fuel tank
explosion and consequent loss of the aeroplane.
For the reasons described above, this [EASA] AD requires the
application of sealant below the FQIS probes in the wing tanks and
below the FQIS probes in the ICWT, as applicable to aeroplane
configuration. * * *
The corrective actions also include revising the aircraft maintenance
program by revising the fuel airworthiness limitations and
incorporating CDCCLs. You may obtain further information by examining
the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (77 FR 18141, March 27,
2012) 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 the 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 (77 FR 18141, March 27, 2012) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 18141, March 27, 2012).
Costs of Compliance
We estimate that this AD will affect 4 products of U.S. registry.
We also estimate that it will take about 8 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $0 per product.
Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these parts. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here. Based
on these figures, we estimate the cost of this AD to the U.S. operators
to be $2,720, or $680 per product.
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://
