ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Fokker Model F27 Mark 100, 200, 300, 400, 500,
600, and 700 series airplanes, that requires a one-time inspection to
determine the part number of the engine mounting frames, brace struts,
and attachment fittings; and related corrective action. This action is
necessary to ensure the structural integrity of the engine-to-wing load
path and prevent possible separation of the engine from the airplane.
This action is intended to address the identified unsafe condition.
DATES: Effective September 3, 2004.
The incorporation by reference of a certain publication listed in
the regulations is approved by the Director of the Federal Register as
of September 3, 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:

FOR FURTHER INFORMATION CONTACT: Tom Groves, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,

227-1503; fax (425) 227-1149.
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 100,
200, 300, 400, 500, 600, and 700 series airplanes was published in the
Federal Register on June 2, 2004 (69 FR 31053). That action proposed to
require a one-time inspection to determine the part number of the
engine mounting frames, brace struts, and attachment fittings; and
related corrective action.
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 41 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 4 work hours per
airplane to accomplish the required actions, and that the average labor
rate is $65 per work hour. Based on these figures, the cost impact of
the AD on U.S. operators is estimated to be $10,660, or $260 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
[[Page 45578]]
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
ADDRESSES.

302-AD.
Applicability: Model F27 Mark 100, 200, 300, 400, 500, 600, and
700 series airplanes; certificated in any category; on which one or
more of the modifications specified in paragraph 1.A.(1) of Fokker
Service Bulletin F27/54-53, dated February 15, 2002, has been done.
Compliance: Required as indicated, unless accomplished
previously.
To ensure the structural integrity of the engine-to-wing load
path and prevent possible separation of the engine from the
airplane, accomplish the following:
One-Time Inspection
(a) Within 24 months after the effective date of this AD: Do a
one-time general visual inspection to determine the part numbers of
the engine mounting frames, brace struts, and attachment fittings;

action per the Accomplishment Instructions of the service bulletin.
Do the related corrective action before further flight.
Note 1: For the purposes of this AD, a general visual inspection
is defined as: ``A visual examination of an interior or exterior
area, installation, or assembly to detect obvious damage, failure,
or irregularity. This level of inspection is made from within
touching distance unless otherwise specified. A mirror may be
necessary to enhance visual access to all exposed surfaces in the
inspection area. This level of inspection is made under normally
available lighting conditions such as daylight, hangar lighting,
flashlight, or droplight and may require removal or opening of
access panels or doors. Stands, ladders, or platforms may be
required to gain proximity to the area being checked.''
