14 CFR Part 39

[Docket No. FAA-2012-0300; Directorate Identifier 2011-NM-276-AD; 
Amendment 39-17086; AD 2012-12-06]
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 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 http://www.regulations.gov 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 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:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 18141, March 27, 2012) for correcting the unsafe condition; 
and
     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.
