14 CFR Part 39

[Docket No. FAA-2012-0141; Directorate Identifier 2011-NM-092-AD; 
Amendment 39-17054; AD 2012-10-05]

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 an in-flight failure of the hydraulic control panel, 
which resulted in the absence of pressure and quantity indication of 
the hydraulic system and accompanying alerts for ``hydraulic system 1 
low quantity'' and ``hydraulic system 2 low quantity.'' This AD 
requires implementing new abnormal procedures for hydraulics in the 
airplane flight manual (AFM). We are issuing this AD to prevent loss of 
control of the airplane due to incorrect hydraulic system failure 
information being provided to the flightcrew, followed by application 
of inappropriate procedures.

DATES: This AD becomes effective June 25, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 25, 
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 February 14, 2012 
(77 FR 8181). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    An in-flight failure of the hydraulic control panel resulted in 
the absence of pressure and quantity indication of the hydraulic 
system and accompanying alerts for ``hydraulic system 1 low 
quantity'' and ``hydraulic system 2 low quantity''. The procedures 
prescribed the shut-off of the engine driven hydraulic pumps, 
resulting in complete absence of hydraulic pressure, which made it 
impossible to hydraulically control the flight controls, including 
the stabiliser. The status information contained in the procedures 
for these alerts may give the false impression that the stabiliser 
is still hydraulically controllable on one channel. The flight crew 
regained control by using the alternate electrically powered 
stabiliser control.
    A safety review revealed that a ``hydraulic system 1 and 2 low 
quantity'' alert could give the right information, however this 
alert is not available in the Flight Warning System. To solve this 
problem, Fokker Services improved the Hydraulic 1(2) Low Quantity 
Procedures in the Airplane Flight Manual (AFM).
    For the reasons described above, this [EASA] AD requires the 
implementation of new abnormal procedures for hydraulics in the AFM.

The unsafe condition is possible loss of control of the airplane due to 
incorrect hydraulic system failure information being provided to the 
flightcrew, followed by application of inappropriate procedures. 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 8181, February 14, 
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

[[Page 29862]]

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 8181, February 14, 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 8181, February 14, 2012).

Costs of Compliance

    We estimate that this AD will affect about 4 products of U.S. 
registry. We also estimate that it will take about 1 work-hour per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this AD to the U.S. operators to be $340, or $85 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://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (77 FR 8181, February 14, 
2012), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office
