Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy
and Gulfstream 200 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
is applicable to all Gulfstream Aerospace LP Model Galaxy and
Gulfstream 200 airplanes. This action requires repetitive inspections
of the internal and external spring sleeves of the aileron artificial
feel unit (AFU) for proper lubrication, and lubrication if necessary.
This action is necessary to prevent ice accumulation due to water
entering the AFU, which could restrict or jam the aileron, resulting in
reduced controllability of the airplane. This action is intended to
address the identified unsafe condition.

SUPPLEMENTARY INFORMATION: The Civil Aviation Administration of Israel
(CAAI), which is the airworthiness authority for Israel, recently
notified the FAA that an unsafe condition may exist on all Gulfstream
Model Galaxy and Gulfstream 200 airplanes. The CAAI advises that there
have been several incidents of reduced aileron control due to water
freezing in the internal and external spring sleeves of the aileron
artificial feel unit (AFU). Investigation revealed a lack of the water
displacing lubricant (Dow Corning 55) that prevents water ingress into
the sleeves of the AFU. Such conditions could restrict or jam the
aileron, which could result in reduced controllability of the airplane.
Explanation of Relevant Service Information
Gulfstream has issued Gulfstream Alert Service Bulletin 200-27A-
230, dated February 18, 2004, which describes procedures for repetitive
inspections of the internal and external spring sleeves of the aileron
AFU for proper lubrication. The service bulletin also describes
procedures for lubrication of the internal and external spring sleeves
and the face of the nut of the AFU with Dow Corning 55 grease, if not
properly lubricated.
The service bulletin refers to Certification Maintenance Procedure
(CMP) Code 271051 of Chapter 05-10-00, of the Gulfstream 200 Airplane
Maintenance Manual (AMM), as an additional source of service
information for accomplishment of the inspection and lubrication of the
internal and external spring sleeves of the aileron AFU.
Accomplishment of the action specified in the service bulletin is
intended to adequately address the identified unsafe condition. The
CAAI classified this service bulletin as mandatory and issued Israeli
airworthiness directive 27-04-02-06, dated February 29, 2004, to ensure
the continued airworthiness of these airplanes in Israel.
FAA's Conclusions
These airplane models are manufactured in Israel and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the CAAI has kept us informed of the
situation described above. We have examined the findings of the CAAI,
reviewed all available information, and determined that AD action is
necessary for products of this type design that are certificated for
operation in the United States.
Explanation of Requirements of Rule
Since an unsafe condition has been identified that is likely to
exist or develop on other airplanes of the same type design registered
in the United States, this AD is being issued to prevent ice
accumulation due to water entering the AFU, which could restrict or jam
the aileron, resulting in reduced controllability of the airplane. This
AD requires repetitive inspections of the internal and external spring
sleeves of the aileron artificial feel unit (AFU) for proper
lubrication, and lubrication if necessary. The actions are required to
be accomplished in accordance with the service bulletin described
previously, except as discussed below.
Difference Between Service Bulletin and This AD
Although the service bulletin referenced in this AD specifies to
submit a service reply card to the manufacturer, this AD does not
include such a requirement.
Clarification of Repetitive Inspection Intervals
Paragraph (a) of this AD requires that the initial inspection and
lubrication of the aileron AFU be repeated at intervals not to exceed
300 flight hours. This interval is cited in CMP Code 271051 of Chapter
05-10-00 of the Gulfstream 200 AMM, as noted in the Accomplishment
[[Page 25484]]
Instructions of the referenced service bulletin.
Determination of Rule's Effective Date
Since a situation exists that requires the immediate adoption of
this regulation, it is found that notice and opportunity for prior
public comment hereon are impracticable, and that good cause exists for
making this amendment effective in less than 30 days.
Comments Invited
Although this action is in the form of a final rule that involves
requirements affecting flight safety and, thus, was not preceded by
notice and an opportunity for public comment, comments are invited on
this rule. Interested persons are invited to comment on this rule by
submitting such written data, views, or arguments as they may desire.
Communications shall identify the Rules Docket number and be submitted
in triplicate to the address specified under the caption ADDRESSES. All
communications received on or before the closing date for comments will
be considered, and this rule may be amended in light of the comments
received. Factual information that supports the commenter's ideas and
suggestions is extremely helpful in evaluating the effectiveness of the
AD action and determining whether additional rulemaking action would be
needed.
Submit comments using the following format:
Organize comments issue-by-issue. For example, discuss a
request to change the compliance time and a request to change the
service bulletin reference as two separate issues.
For each issue, state what specific change to the AD is
being requested.
Include justification (e.g., reasons or data) for each
request.
Comments are specifically invited on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify the rule. All comments submitted will be
available, both before and after the closing date for comments, in the
Rules Docket for examination by interested persons. A report that
summarizes each FAA-public contact concerned with the substance of this
AD will be filed in the Rules Docket.
Commenters wishing the FAA to acknowledge receipt of their comments
submitted in response to this rule must submit a self-addressed,
stamped postcard on which the following statement is made: ``Comments
to Docket Number 2004-NM-70-AD.'' The postcard will be date stamped and
returned to the commenter.
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.
The FAA has determined that this regulation is an emergency
regulation that must be issued immediately to correct an unsafe
condition in aircraft, and that it is not a ``significant regulatory
action'' under Executive Order 12866. It has been determined further
that this action involves an emergency regulation under DOT Regulatory
Policies and Procedures (44 FR 11034, February 26, 1979). If it is
determined that this emergency regulation otherwise would be
significant under DOT Regulatory Policies and Procedures, a final
regulatory evaluation will be prepared and placed in the Rules Docket.
A copy of it, if filed, may be obtained from the Rules Docket at the
location provided under the caption ADDRESSES.
