Airworthiness Directives; Dassault Model Falcon 10 and Model
Mystere-Falcon 50 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes the adoption of a new airworthiness
directive (AD) that is applicable to certain Dassault Model Falcon 10
and Model Mystere-Falcon 50 series airplanes. For certain airplanes,
this proposal would require modification of the aircraft wiring to
illuminate the ``T/O CONFIG'' red warning light on the cockpit warning
panel. For certain other airplanes, this proposal would require
installation of a ``NO TAKEOFF'' red light on each pilot's instrument
panel; modification of the associated aircraft wiring to activate the
lights whenever the aircraft is not in the proper configuration for
take-off; and a revision to the Airplane Flight Manual to check that
the ``NO TAKEOFF'' lights are out prior to take-off. This proposal is
prompted by issuance of mandatory continuing airworthiness information
by a foreign civil airworthiness authority. The actions specified by
the proposed AD are intended to prevent take-off with the parking brake
engaged, which could result in an extended take-off roll or a rejected
take-off, and consequent runway overrun.
DATES: Comments must be received by August 23, 1999.

Discussion
The Direction Generale de l'Aviation Civile (DGAC), which is the
airworthiness authority for France, notified the FAA that an unsafe
condition may exist on certain Dassault Model Falcon 10 and Model
Mystere-Falcon 50 series airplanes. The DGAC advises that, during take-
off of a Model Mystere-Falcon 50 airplane, the pilot reported that the
engine parameters were correct, but longitudinal acceleration displayed
on the electronic flight instrumentation system (EFIS) was lower than
usual. The pilot chose to reject the take-off attempt. The DGAC also
advises that several similar occurrences have been reported on Model
Falcon 10 series airplanes. The slow acceleration is thought to have
been caused by the pilot attempting to take-off with the parking brake
engaged. The existing design for both models provides appropriate
indication to the crew when the parking brake handle is not released
during the takeoff; however, the indication is not readily visible. Due
to its location in the lower part of the pilot's instrument panel, it
is outside of the pilot's direct line of sight and the indication may
be unnoticed. This condition, if not corrected, could result in an
extended take-off roll or a rejected take-off, and consequent runway
overrun.
Explanation of Relevant Service Information
Dassault has issued Service Bulletin F50-240, Revision 1, dated
October 7, 1998 for Model Mystere-Falcon 50 series airplanes), which
describes procedures for modification of the aircraft wiring to add the
``park brake handle not pushed forward'' condition in the illumination
conditions of the ``T/O CONFIG'' red warning light on the cockpit
warning panel.
Dassault also has issued Service Bulletin F10-280, Revision 1,
dated February 10, 1999 (for Model Falcon 10 series airplanes), which
describes procedures for installation of a ``NO TAKEOFF'' red light on
each pilot's instrument panel. The service bulletin also describes
procedures for modification of the associated aircraft wiring to
activate the lights whenever the aircraft is not in the proper
configuration for take-off; and a revision to the Normal Procedures
Section of the Falcon 10 Airplane Flight Manual to check that the ``NO
TAKEOFF'' lights are out prior to take-off.
Accomplishment of the actions specified in the service bulletins is
intended to adequately address the identified unsafe condition. The
DGAC classified these service bulletins as mandatory and issued French
airworthiness directives 98-300-022(B), dated July 29, 1998, and 98-
547-022(B), dated December 30, 1998, in order to assure the continued
airworthiness of these airplanes in France.
FAA's Conclusions
These airplane models are manufactured in France 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 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 Proposed 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, the proposed AD would require accomplishment of
the actions specified in the service bulletins described previously.
Cost Impact
The FAA estimates that 36 Dassault Model Falcon 10 series airplanes
of U.S. registry would be affected by this proposed AD.
It would take approximately 50 work hours per airplane to
accomplish the proposed installation, at an average labor rate of $60
per work hour. Required parts would cost approximately $2,280 per
airplane. Based on these figures, the cost impact of the installation
proposed by this AD on U.S. operators is estimated to be $190,080, or
$5,280 per airplane.
It would take approximately 1 work hour per airplane to accomplish
the proposed revision to the AFM, at an average labor rate of $60 per
work hour. Based on these figures, the cost impact of the AFM revision
proposed by this AD on U.S. operators is estimated to be $2,160, or $60
per airplane.
The FAA estimates that 115 Dassault Model Mystere-Falcon 50 series
airplanes of U.S. registry would be affected by this proposed AD, that
it would take approximately 8 work hours per airplane to accomplish the
proposed modification, and that the average labor rate is $60 per work
hour. Required parts would cost approximately $6,000 per airplane.
Based on these figures, the cost impact of the modification proposed by
this AD on U.S. operators is estimated to be $745,200, or $6,480 per
airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the proposed requirements
of this AD action, and that no operator would accomplish those actions
in the future if this AD were not adopted.
Regulatory Impact
The regulations proposed herein would 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
proposal would not have sufficient federalism implications to warrant
the preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this proposed
regulation (1) is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule'' under the DOT
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
and (3) if promulgated, 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 copy of the draft
regulatory evaluation prepared for this action is contained in the
Rules Docket. A copy of it may be obtained by contacting the Rules
Docket at the location provided under the caption ADDRESSES.

The Proposed Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend
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. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
Dassault Aviation: Docket 98-NM-325-AD.
Applicability: Model Falcon 10 series airplanes, serial numbers
1 through 152 inclusive, on which Dassault Modification M801
(reference Dassault Service Bulletin F10-280, Revision 1, dated
February 10, 1999) has not been accomplished; and Model Mystere-
Falcon 50 series airplanes, serial numbers 2 through 250 inclusive
and 252, on which Dassault Modification M1850 (reference Dassault
Service Bulletin F50-240, Revision 1, dated October 7, 1998) has not
been accomplished; certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
otherwise 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 request approval for an
alternative method of compliance in accordance with paragraph (c) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent take-off with the parking brake engaged, which could
result in an extended take-off roll or a rejected take-off, and
consequent runway overrun, accomplish the following:
Model Mystere-Falcon 50 Series Airplanes: Modification
(a) For Model Mystere-Falcon 50 series airplanes, within 9
months after the effective date of this AD, modify the aircraft
wiring to add the ``park brake handle not pushed forward'' condition
in the illumination conditions of the ``T/O CONFIG'' red warning
light on the cockpit warning panel in accordance with Dassault
Service Bulletin F50-240, Revision 1, dated October 7, 1998.
Model Falcon 10 Series Airplanes: Modification and AFM Revision
(b) For Dassault Falcon 10 series airplanes, within 9 months
after the effective date of this AD, accomplish the requirements of
paragraphs (b)(1) and (b)(2) of this AD in accordance with Dassault
Service Bulletin F10-280, Revision 1, dated February 10, 1999.
(1) Install a ``NO TAKEOFF'' red light on each pilot's
instrument panel and modify the associated aircraft wiring to
activate the lights whenever the aircraft is not in the proper
configuration for take-off.
(2) Revise the Normal Procedures Section of the FAA-approved
Airplane Flight Manual (AFM) to include the information specified in
Falcon 10 AFM DTM722 Temporary Change No. 17, dated March 31, 1995,
which introduces procedures for checking that the ``NO TAKEOFF''
lights are out prior to take-off; and operate the airplane in
accordance with those limitations and procedures.
Note 2: This may be accomplished by inserting a copy of Falcon
10 AFM DTM722 Temporary Change No. 17 in the AFM. When these
temporary revisions have been incorporated into general revisions of
the AFM, the general revisions may be inserted in the AFM, provided
the information contained in the general revision is identical to
that specified in Temporary Change No. 17.
Alternative Methods of Compliance
(c) 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, International Branch, ANM-116, 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, International
Branch, ANM-116.
Note 3: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the International Branch, ANM-116.
Special Flight Permits
(d) 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.
