Airworthiness Directives; Dassault Model Mystere-Falcon 50 and 
900 Series Airplanes, and Model Falcon 2000 and 900EX Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Dassault Model Mystere-Falcon 50 and 900 series 
airplanes, and Model Falcon 2000 and 900EX series airplanes. This 
proposal requires temporary changes to the Airplane Flight Manual to 
prohibit the use of certain functions depending on whether or not the 
operator chooses to deactivate the global positioning system (GPS). For 
airplanes on which the GPS is deactivated, this proposal requires 
installing a deactivation locking collar on certain circuit breakers. 
For certain airplanes, this proposal also requires modifying the wiring 
of the global positioning/inertial reference system. This action is 
necessary to prevent the erroneous cockpit display of ground speed, 
wind velocity and direction, flight path angle, and true track angle 
when using certain autopilot and/or flight management system functions. 
Erroneous cockpit displays could cause the pilot to lose situational 
awareness, and possibly lose control of the airplane. This action is 
intended to address the identified unsafe condition.

DATES: Effective July 13, 2005.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 13, 2005.

ADDRESSES: The service information referenced in this AD may be 
obtained from Dassault Falcon Jet, P.O. Box 2000, South Hackensack, New 
Jersey 07606.

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 Dassault Model Mystere-
Falcon 50 and 900 series airplanes, and Model Falcon 2000 and 900EX 
series airplanes, was published in the Federal Register on April 27, 
2004 (69 FR 22745). That action proposed to require temporary changes 
to the Airplane Flight Manual (AFM) to prohibit the use of certain 
functions depending on whether or not the operator chooses to 
deactivate the global positioning system (GPS). For airplanes on which 
the GPS is deactivated, that action proposed to require installing a 
deactivation locking collar on certain circuit breakers. For certain 
airplanes, that action proposed to require modifying the wiring of the 
global positioning/inertial reference system (GP/IRS).

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

Request To Change Applicability

    One commenter, an airplane operator, requests that the proposed 
applicability be changed to exclude airplanes that are equipped with 
Universal Navigation (UNS-1C) flight management systems with self-
contained GPS. The commenter points out that airplanes with UNS-1C do 
not display the unsafe condition identified in the proposal. The 
commenter states that it is not clear in the proposal whether or not 
the applicability includes airplanes with UNS-1C.
    We do not agree with the commenter. The airplane manufacturer 
advises that airplanes may have been delivered with the UNS-1C system 
installed, but states that there is no assurance that these airplanes 
have not since been modified into a condition that will exhibit the 
unsafe condition. The manufacturer has addressed this issue in the 
service bulletins listed in the proposal. In addition, the 
applicability statement already specifies that the proposal applies 
only to airplanes that are

[[Page 33341]]

equipped with the subject Gp/IRS, and specifies the GP/IRS by part 
number. We have not changed the final rule for this issue.

Request To Revise the Proposal To Account for Airplanes Equipped With 
Different Avionics

    Another commenter, an avionics manufacturer, requests that the 
proposal be revised to account for airplanes that are not equipped with 
the subject GP/IRS, but are instead equipped with different avionics. 
The commenter points out that airplanes equipped with the different 
avionics have a different GPS. The commenter wishes to avoid loss of 
function by operators of Falcon airplanes that are equipped with the 
different avionics.
    We disagree with the request to revise the proposal. The 
applicability statement already specifies that the proposal applies 
only to airplanes that are equipped with the subject GP/IRS, and 
specifies the GP/IRS by part number. Therefore, the proposal does not 
apply to airplanes equipped with the different avionics that have a 
different GPS. In addition, the commenter provides various edits to the 
preamble of the proposal, but does not suggest any substantive changes 
to the body of the AD or provide data to support its position. The 
preamble contains information that is not usually carried over to the 
final rule. We have not changed the final rule in this regard.

Request To Remove ``Interim Action'' Paragraph

    The same commenter requests that we remove the paragraph titled 
``Interim Action'' in the proposal. The commenter states that there is 
an interim step in the proposal, which is the option to pull the GPS 
circuit breakers or to fly with a navigational restriction. The 
commenter further states, however, that the proposal also provides the 
terminating action of a wiring modification, which cancels both the 
option of pulling the GPS circuit breakers and the navigational 
restrictions. In the commenter's opinion, this wiring modification 
represents the final action in the proposal.
    We agree with the commenter that the proposal is not interim 
action. The actions described in paragraphs (c) and (d) of the proposal 
are terminating action for the pulled GPS circuit breakers and the 
navigational restrictions. We have removed the ``Interim Action'' 
paragraph from the final rule.

Request To Clarify Statement of Unsafe Condition

    One commenter, the airplane manufacturer, requests that we clarify 
the statement of the unsafe condition. This statement is located above 
paragraph (a) and in the ``Summary'' paragraph of the proposal. The 
commenter states that the unsafe condition, as worded in the proposed 
AD, does not have enough detailed information to be clear and accurate 
for readers.
    We agree with the commenter. The revisions to the statement, 
provided by the commenter, clarify the unsafe condition. Therefore, we 
have revised the statement in the final rule to incorporate the 
commenter's suggestions.

Request To Revise Service Bulletin Dates

    One commenter, the airplane manufacturer, notes that the dates on 
some of the referenced service bulletins are incorrect. The commenter 
states that all service bulletins should be dated October 29, 2003.
    We agree that the proposal should have the correct dates for all 
service bulletins. We examined the copies of the service bulletins that 
we had when we wrote the proposal, and found that four are dated 
October 15, 2003. We discussed this discrepancy with the commenter and 
determined that the service bulletins dated October 15, 2003, are 
review copies that were sent to the FAA and to the Direction 
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) for concurrence. We 
requested that the commenter provide us with copies of the four service 
bulletins, dated October 29, 2003, and found that the procedures in the 
four service bulletins dated October 29, 2003, are virtually identical 
to those dated October 15, 2003. As listed in the following table, the 
October 15 service bulletins and the October 29 service bulletins have 
the same revision level.

                                   Service Bulletin Dates and Revision Levels
----------------------------------------------------------------------------------------------------------------
     Dassault service bulletin         Review copy date       Final copy date             Revision level
----------------------------------------------------------------------------------------------------------------
F900-318..........................  October 15, 2003.....  October 29, 2003.....  1.
F900-324..........................  October 15, 2003.....  October 29, 2003.....  Original.
F900EX-190........................  October 15, 2003.....  October 29, 2003.....  Original.
F2000-285.........................  October 15, 2003.....  October 29, 2003.....  Original.
----------------------------------------------------------------------------------------------------------------

    The manufacturer assures us that no members of the public received 
review copies of the service bulletins, dated October 15, 2003. 
Therefore, we have changed the final rule to reference the October 29, 
2003, final versions of the service bulletins as the acceptable source 
of service information for the applicable actions in the final rule.

Request To Revise Paragraph (d) To Include Terminating Action for 
Certain Airplanes

    One commenter, the airplane manufacturer, does not agree with 
paragraph (c) of the proposal. The commenter, the airplane 
manufacturer, states that deactivating the GPS is not the specific 
terminating action for the F2000 airplane with head-up display (HUD), 
or for the Falcon 50 airplane. The commenter requests that we revise 
paragraph (d) to reflect the appropriate terminating action for these 
airplanes; this terminating action is either following the navigational 
restrictions or deactivating the GPS.
    We partially agree with the commenter. We agree that the language 
of proposed paragraph (c) is misleading because it states that 
deactivating the GPS is the only terminating action for these 
airplanes. However, we do not agree with the recommendation to revise 
paragraph (d) to reflect the appropriate information. We have 
determined that paragraph (b) is the appropriate place to put the 
requested change. Paragraph (b) of the proposal requires that operators 
revise the limitations section of the AFM to allow either following the 
navigational restrictions or deactivating the GPS. Also, we realize 
that an MF50 service bulletin (Falcon 50 Service Bulletin F50-416, 
dated October 29, 2003) was referenced in the proposal as being 
required for the mandatory wiring modification. This was an error, as 
that action is not mandatory for the MF50, and also is not consistent 
with the

[[Page 33342]]

French airworthiness directive. Therefore, we have revised Table 2 in 
paragraph (a)(2) to remove the reference to Falcon 50 Service Bulletin 
F50-416, dated October 29, 2003; and paragraphs (b)(3) and (b)(4) of 
the final rule to reflect the appropriate terminating action and 
include the commenter's requested change.

Request To Clarify Compliance Time in Paragraph (c)

    The same commenter notes that the ``prior to further flight'' 
statement in paragraph (c) of the proposal does not correspond with the 
seven-day compliance time for revising the AFM that is required by 
paragraph (b) of the proposal. The commenter further notes that the 
seven-day compliance time is referenced in the paragraph titled 
``Differences Between French Airworthiness Directive and This Proposed 
AD.''
    From this comment we infer that the compliance time for paragraph 
(c) is unclear. Paragraph (b) of the proposal requires that operators 
revise the AFM within seven days after the effective date of the AD, 
and, thereafter, to operate the airplane within the limitations 
specified by the AFM revision. For some airplanes, one of those 
limitations is to deactivate the GPS. The opening sentence of paragraph 
(c) of the proposal states, ``For airplanes on which the GPS is 
deactivated in accordance with the applicable temporary change (TC) 
specified in paragraph (b) of this AD: Prior to further flight, install 
a deactivation locking collar * * *.'' The purpose of paragraph (c) is 
to ensure that operators who deactivate the GPS in accordance with the 
AFM limitations referenced in paragraph (b) of the proposal will 
install a locking collar prior to further flight after deactivating the 
GPS. The AFM revision is required within seven days after the effective 
date of the proposal, therefore the limitations in the AFM (including 
deactivating the GPS) are not required until seven days after the 
effective date of the final rule. To ensure that this compliance time 
is clear, we have changed paragraph (c) of the final rule to state, 
``Prior to further flight after deactivating the GPS.''

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 543 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 1 work hour per 
airplane to accomplish the TCs to the AFM, and that the average labor 
rate is $65 per work hour. Based on these figures, the cost impact of 
the AD on U.S. operators is estimated to be $35,295, or $65 per 
airplane.
    For airplanes that require the wiring modification required by this 
AD, we estimate that it will take approximately 2 work hours per 
airplane to accomplish the modification. Based on these figures, the 
cost impact of this action on U.S. operators is estimated to be $130 
per airplane.
    The cost impact figures discussed above are 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
