Airworthiness Directives; Dassault Model Falcon 10 Series
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 Dassault Model Falcon 10 series airplanes. This
action requires an inspection to verify proper installation of the pins
in the dual non-return valves of the fire extinguishing system for the
engines, and replacement of any defective valve with a new valve. This
action is necessary to prevent failure of a fire extinguisher bottle to
discharge, which could result in the inability to extinguish a fire in
an engine. This action is intended to address the identified unsafe
condition.
DATES: Effective July 12, 2001.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 12, 2001.
Comments for inclusion in the Rules Docket must be received on or
before July 27, 2001.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-114,

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile
(DGAC), which is the airworthiness authority for France recently
notified the FAA that an unsafe condition may exist on all Dassault
Model Falcon 10 series airplanes. The DGAC advises that, during routine
maintenance, when removing a fire extinguishing bottle that had
accidentally discharged, it was
[[Page 34086]]
found that the charge from the bottle had been trapped in the discharge
line. Investigation revealed that a pin had not been correctly
installed in the non-return valve during manufacture. The pin is
normally located across the valve body to prevent the shuttle-ball from
blocking the outlet to the engine. If the pin is located too close to
the edge of the valve body, the shuttle-ball may block the discharge
outlet and prevent the charge from releasing into the engine during an
engine fire. Such conditions, if not corrected, could result in the
inability to extinguish a fire in an engine.
Explanation of Relevant Service Information
Dassault has issued Service Bulletin F10-A291, dated June 1, 2001,
which describes procedures for an inspection to verify proper
installation of the pins in the dual non-return valves of the fire
extinguishing system for the engines, and replacement of any defective
valve with a new valve. A defective valve is described as any valve
with a pin found outside the identified tolerance range. Accomplishment
of the actions specified in the service bulletin is intended to
adequately address the identified unsafe condition. The DGAC classified
this service bulletin as mandatory and issued French airworthiness
directive T2001-219-025(B), dated June 1, 2001, in order to assure the
continued airworthiness of these airplanes in France.
FAA's Conclusions
This airplane model is manufactured in France and is 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 DGAC has kept the FAA informed
of the situation described above. The FAA has examined the findings of
the DGAC, 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 failure of a
fire extinguisher bottle to discharge, which could result in the
inability to extinguish a fire in an engine. This AD requires an
inspection to verify proper installation of the pins in the dual non-
return valves of the fire extinguishing system for the engines, and
replacement of any defective valve with a new valve. The actions are
required to be accomplished in accordance with the service bulletin
described previously.
Difference Between This AD, Service Bulletin, and Foreign
Airworthiness Directive
This AD differs from the service bulletin and the parallel French
airworthiness directive in that it requires accomplishment of the
inspection within 10 days after the effective date of this AD. In
developing an appropriate compliance time for this AD, the FAA
considered not only the DGAC's recommendation, but the degree of
urgency associated with addressing the subject unsafe condition, the
average utilization of the affected fleet, and the time necessary to
perform the inspection (one hour). In light of all of these factors,
the FAA finds a 10-day compliance time for completing the required
actions to be warranted, in that it represents an appropriate interval
of time allowable for affected airplanes to continue to operate without
compromising safety.
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 2001-NM-191-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.
