Federal Register Abstract
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Fokker Model F.28 Mark 0070 series airplanes, that currently requires a one-time inspection to detect loose bolts attaching the gustlock counter-bracket to the pulley on the elevator tension regulator (control) assembly, and corrective action if necessary. This AD instead requires a modification of the elevator tension control mechanism. This AD also revises the applicability to include additional airplanes. The actions specified by this AD are intended to prevent restricted elevator movement and consequent reduced controllability of the airplane. This AD is intended to address the identified unsafe condition.

AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to certain Fokker Model F.28 Mark 0070 series
airplanes, that currently requires a one-time inspection to detect
loose bolts attaching the gustlock counter-bracket to the pulley on the
elevator tension regulator (control) assembly, and corrective action if
necessary. This AD instead requires a modification of the elevator
tension control mechanism. This AD also revises the applicability to
include additional airplanes. The actions specified by this AD are
intended to prevent restricted elevator movement and consequent reduced
controllability of the airplane. This AD is intended to address the
identified unsafe condition.
DATES: Effective August 5, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of August 5, 2004.
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 National
Archives and Records Administration (NARA). For information on the
availability of this material at NARA, call (202) 741-6030, or go to:

International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 2000-09-11,
amendment 39-11720 (65 FR 30529, May 12, 2000), which is applicable to
certain Fokker Model F.28 Mark 0070 series airplanes, was published in
the Federal Register on April 15, 2004 (69 FR 19950). The proposed AD
would require modifying the elevator tension control mechanism and
revising the applicability to include additional airplanes.
Comments
We provided the public the opportunity to participate in developing
this AD. No comments have been submitted on the proposed AD or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Cost Impact
This AD affects about 75 airplanes of U.S. registry. The actions
take about 1 work hour per airplane, at an average labor rate of $65
per work hour. Required parts will be provided to operators at no cost.
Based on these figures, the cost impact of the AD on U.S. operators is
estimated to be $4,875, or $65 per airplane.
The cost impact figure discussed above is 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. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
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
