RIN 2120-AA64
Airworthiness Directives; Fokker Model F27 Mark 050, 200, 500,
and 600 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Fokker Model F27 Mark 050, 200, 500, and 600
series airplanes, that requires installation of certain components, and
revisions of the Airplane Flight Manual. This action is necessary to
prevent undetected failures of the horizontal and vertical stabilizer
de-icing system, which could result in reduced controllability of the
airplane. This action is intended to address the identified unsafe
condition.
DATES: Effective April 12, 2000.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of April 12, 2000.
ADDRESSES: The service information referenced in this AD may be
obtained from Fokker Services B.V., P.O. Box 231, 2150 AE Nieuw-Vennep,
the Netherlands. This information may be examined at the Federal
Aviation Administration (FAA), Transport Airplane Directorate, Rules
Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of
the Federal Register, 800 North Capitol Street, NW., suite 700,
Washington, DC.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Fokker Model F27 Mark 050,
200, 500, and 600 series airplanes was published in the Federal
Register on January 4, 2000 (65 FR 251). That action proposed to
require installation of certain components, and revisions of the
Airplane Flight Manual (AFM).

Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
The FAA estimates that 37 airplanes of U.S. registry will be
affected by this AD.
It will take approximately 1 work hour per airplane to accomplish
the required. AFM revision for operation of the airplane in the event
of a failure of the de-icing system, at an average labor rate of $60
per work hour. Based on these figures, the cost impact of this required
AFM revision on U.S. operators is estimated to be $2,220, or $60 per
airplane.
It will take approximately 125 work hours per airplane to
accomplish the required installations, at an average labor rate of $60
per work hour. Required parts will cost approximately $11,000 per
airplane. Based on these figures, the cost impact of the required
installations on U.S. operators is estimated to be $684,500, or $18,500
per airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted.
None of the Model F27 Mark 050 series airplanes affected by this
action are on the U.S. Register. Should an affected airplane be
imported and placed on the U.S. Register in the future, it will take
approximately 1 work hour per airplane to accomplish the required AFM
revision for checks of the de-icing system, at an average labor rate of
$60 per work hour. Based on these figures, the cost impact of this
required AFM revision on U.S. operators is estimated to be $60 per
airplane.
Regulatory Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) 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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
