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 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.

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 <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 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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (77 FR 8181, February 14, 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 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; 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
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.
