Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy 
and Model Gulfstream 200 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Gulfstream Aerospace LP Model Galaxy and Model 
Gulfstream 200 airplanes, that requires a one-time detailed inspection 
of the wing flap actuators for proper bonding of the flap actuator 
fairings to the lower skin of the wings, and related corrective or 
preventative actions. These actions are necessary to prevent possible 
separation of the flap actuator fairings from the lower skin of the 
wings from causing possible damage to adjacent structural elements 
(such as the horizontal stabilizer), which could result in reduced 
controllability of the airplane. These actions are intended to address 
the identified unsafe condition.

DATES: Effective September 14, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 14, 2004.

ADDRESSES: The service information referenced in this AD may be 
obtained from Gulfstream Aerospace Corporation, P.O. Box 2206, Mail 
Station D-25, Savannah, Georgia 31402. 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

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer; 
International Branch, ANM-116, FAA, Transport Airplane Directorate,

227-2125; 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 Gulfstream Aerospace LP 
Model Galaxy and Model Gulfstream 200 airplanes was published in the 
Federal Register on April 29, 2004 (69 FR 23458). That action proposed 
to require a one-time detailed inspection of the wing flap actuators 
for proper bonding of the flap actuator fairings to the lower skin of 
the wings, and related corrective or preventative actions.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments have been submitted on the 
proposed AD or on the determination of the cost to the public.

Clarification of Service Bulletin Issue Date

    Although Gulfstream Aerospace LP Alert Service Bulletin 200-57A-
161, Revision 1, dated November 7, 2002, shows November 5, 2002, as the 
date of the original issue of the service bulletin, the actual date of 
the original issue of the service bulletin is November 6, 2002. There 
are no other revisions of this service bulletin. We have revised 
Paragraph (d) of this AD to specify the original issue date of the 
service bulletin as November 6, 2002.

Conclusion

    After careful review of the available data, including the comments 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule with the changes described 
previously. The FAA has determined that these changes will neither 
increase the economic burden on any operator nor increase the scope of 
the AD.

Cost Impact

    The FAA estimates that 60 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 13 work hours per 
airplane to accomplish the required actions, and that the average labor 
rate is $65 per work hour. Required parts will be supplied free of 
charge by the manufacturer. Based on these figures, the cost impact of 
the AD on U.S. operators is estimated to be $50,700, or $845 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 
ADDRESSES.

Industries, Ltd.): Amendment 39-13759. Docket 2002-NM-325-AD.

    Applicability: Model Galaxy and Model Gulfstream 200 airplanes, 
serial numbers 004 through 074 inclusive; certificated in any 
category.
    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent possible separation of the flap actuator fairings 
from the lower skin of the wings from causing possible damage to 
adjacent structural elements (such as the horizontal stabilizer), 
which could result in reduced controllability of the airplane, 
accomplish the following:

Inspection

    (a) Within 30 flight hours or 5 flight cycles after the 
effective date of this AD, whichever occurs earlier, perform a one-
time detailed inspection of the wing flap actuators for proper 
bonding of the flap actuator fairings to the lower skin of the 
wings; in accordance with Part A of the Accomplishment Instructions 
of Gulfstream Aerospace LP Alert Service Bulletin 200-57A-161, 
Revision 1, dated November 7, 2002.

    Note 1:  For the purposes of this AD, a detailed inspection is 
defined as: ``An intensive visual examination of a specific 
structural area, system, installation, or assembly to detect damage, 
failure, or irregularity. Available lighting is normally 
supplemented with a direct source of good lighting at intensity 
deemed appropriate by the inspector. Inspection aids such as mirror, 
magnifying lenses, etc., may be used. Surface cleaning and elaborate 
access procedures may be required.''

Reinforcement of Actuator Fairing Adhesive

    (b) If the inspection required by paragraph (a) of this AD 
reveals either no separation or separation of the flap actuator 
fairings from the lower skin of the wings that is within the limits 
specified in Gulfstream Aerospace LP Alert Service Bulletin 200-57A-
161, Revision 1, dated November 7, 2002, do paragraphs (b)(1) and 
(b)(2) of this AD.
    (1) Prior to further flight, apply sealant around the edges of 
the fairings, in accordance with Part A of the Accomplishment 
Instructions of the service bulletin.

this AD, remove and reattach the flap actuator fairings in 
accordance with Part B of the Accomplishment Instructions of the 
service bulletin.

Removal and Reattachment of Actuator Fairings

    (c) If the inspection required by paragraph (a) of this AD 
reveals separation of the flap actuator fairings from the lower skin 
of the wings that is outside the limits specified in Gulfstream 
Aerospace LP Alert Service Bulletin 200-57A161, Revision 1, dated 
November 7, 2002: Prior to further flight, remove and reattach the 
flap actuator fairings in accordance with Part B of the 
Accomplishment Instructions of the service bulletin.

    (d) Actions accomplished before the effective date of this AD 
per Gulfstream Aerospace LP Alert Service Bulletin 200-57A-161, 
dated November 6, 2002, are considered acceptable for compliance 
with corresponding actions specified in this AD.

Reporting Requirements
