[Docket No. 94-NM-227-AD; Amendment 39-9114; AD 95-01-03]
Airworthiness Directives; Dassault Aviation Model Mystere-Falcon
50 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 certain Dassault Aviation Model Mystere-Falcon 50
series airplanes. This action requires measurement of the clearance
between the electrical bundles in the left-hand cabinet of the
electrical panel and the counterbalancing actuator of the passenger
door, and rerouting and clamping the wire bundles, if necessary. This
amendment is prompted by a report of damage of the wire bundles between
the actuator of the passenger door and the left-hand cabinet of the
electrical panel. The actions specified in this AD are intended to
prevent an electrical fire due to damage of the electrical wire
bundles.
DATES: Effective on January 18, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of January 18, 1995.
Comments for inclusion in the Rules Docket must be received on or
before March 6, 1995.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-103,

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 certain Dassault
Aviation Model Mystere-Falcon 50 series airplanes. The DGAC advises
that it has received a report of damage of the wire bundles between the
actuator of the passenger door and the left-hand cabinet of the
electrical panel. Investigation revealed that the cause of this damage
may be attributed to insufficient clearance between the left-hand
cabinet and the counterbalancing actuator of the passenger door. This
condition, if not corrected, could result in the potential for an
electrical fire due to damage of the electrical wire bundles.
Dassault Aviation has issued Alert Service Bulletin F50-A243 (F50-
A39-1), Revision 1, dated November 10, 1994, which describes procedures
for measuring the clearance between the electrical bundles in the left-
hand cabinet and the counterbalancing actuator of the passenger door,
and rerouting and clamping the wire bundles if the clearance is outside
the limits specified in the alert service bulletin. The French DGAC
classified this alert service bulletin as mandatory and issued French
airworthiness directive 94-238-015(B), dated November 9, 1994, in order
to assure the continued airworthiness of these airplanes in France.
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 French DGAC has kept the FAA
informed of the situation described above. The FAA has examined the
findings of the French 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.
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 an electrical
fire due to damage of the electrical wire bundles. This AD requires
measurement of the clearance between the electrical bundles in the
left-hand cabinet and the counterbalancing actuator of the passenger
door, and rerouting and clamping of the wire bundles, if necessary. The
actions are required to be accomplished in accordance with the alert
service bulletin described previously.
As a result of recent communications with the Air Transport
Association (ATA) of America, the FAA has learned that, in general,
some operators may misunderstand the legal effect of AD's on airplanes
that are identified in the applicability provision of the AD, but that
have been altered or repaired in the area addressed by the AD. The FAA
points out that all airplanes identified in the applicability provision
of an AD are legally subject to the AD. If an airplane has been altered
or repaired in the affected area in such a way as to affect compliance
with the AD, the owner or operator is required to obtain FAA approval
for an alternative method of compliance with the AD, in accordance with
the paragraph of each AD that provides for such approvals. A note has
been included in this rule to clarify this requirement.
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.
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 94-NM-227-AD.'' The postcard will be date stamped and
returned to the commenter.
The regulations adopted herein will not have substantial direct
effects 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, in
accordance with Executive Order 12612, it is determined that this final
rule does not have sufficient federalism implications to warrant the
preparation of a Federalism Assessment.
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.

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
[[Page 5]] Administrator, the Federal Aviation Administration amends
part 39 of the Federal Aviation Regulations (14 CFR part 39) as
follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. App. 1354(a), 1421 and 1423; 49 U.S.C.
106(g); and 14 CFR 11.89.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
95-01-03 Dassault Aviation: Amendment 39-9114. Docket 94-NM-227-AD.
Applicability: Model Mystere-Falcon 50 series airplanes having
serial numbers 2 through 232 inclusive, certificated in any
category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must use the authority
provided in paragraph (b) to request approval from the FAA. This
approval may address either no action, if the current configuration
eliminates the unsafe condition; or different actions necessary to
address the unsafe condition described in this AD. Such a request
should include an assessment of the effect of the changed
configuration on the unsafe condition addressed by this AD. In no
case does the presence of any modification, alteration, or repair
remove any airplane from the applicability of this AD.
Compliance: Required as indicated, unless accomplished
previously.
To prevent an electrical fire due to damage of the electrical
wire bundles, accomplish the following:
(a) Within 20 days after the effective date of this AD, measure
the clearance between the electrical bundles in the left-hand
cabinet and the counterbalancing actuator of the passenger door, in
accordance with Dassault Aviation Alert Service Bulletin F50-A243
(F50-A39-1), Revision 1, dated November 10, 1994.
(1) If the clearances are within the limits specified in the
alert service bulletin, no further action is required by this AD.
(2) If the clearances are outside the limits specified in the
alert service bulletin, prior to further flight, reroute and clamp
the wire bundles in accordance with the alert service bulletin.
(b) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, Standardization Branch, ANM-113,
FAA, Transport Airplane Directorate. Operators shall submit their
requests through an appropriate FAA Principal Maintenance Inspector,
who may add comments and then send it to the Manager,
Standardization Branch, ANM-113.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Standardization Branch, ANM-113.
(c) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
(d) The measuring, rerouting, and clamping shall be done in
accordance with Dassault Aviation Alert Service Bulletin F50-A243
(F50-A39-1), Revision 1, dated November 10, 1994. This incorporation
by reference was approved by the Director of the Federal Register in
