DEPARTMENT OF TRANSPORTATION
14 CFR Part 39
[Docket No. 94-NM-200-AD; Amendment 39-9378; AD 95-19-16]
Airworthiness Directives; Dassault Aviation Model Mystere-Falcon
900 Series Airplanes Equipped With Fairchild Model F800 Flight Data
Recorders, Installed in Accordance With Supplemental Type Certificate
(STC) SA7255SW-D
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Dassault Aviation Model Mystere-Falcon 900 series
airplanes, that requires modification of the electrical power
installation of the
[[Page 51708]]
flight data recorder, replacement of the currently installed socket box
for ground power with a reworked socket box, and performance of checks
and tests. This amendment is prompted by reports indicating that the
generators may shut down due to an intermittent relay failure of the
flight data recorders. The actions specified by this AD are intended to
prevent loss of electrical power to the airplane due to generator
outage.
DATES: Effective November 2, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of November 2, 1995.
ADDRESSES: The service information referenced in this AD may be
obtained from Falcon Jet Corporation, P.O. Box 967, Little Rock,
Arkansas 72203-0967. This information may be examined at the Federal
Aviation Administration (FAA), Transport Airplane Directorate, Rules
Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of
the Federal Register, 800 North Capitol Street, NW., suite 700,
Washington, DC.
FOR FURTHER INFORMATION CONTACT: Charles Huber, Aerospace Engineer,
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate,

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 Aviation Model
Mystere-Falcon 900 series airplanes equipped with Fairchild Model F800
flight data recorders, installed in accordance with Supplemental Type
Certificate (STC) SA7255SW-D, was published in the Federal Register on
January 18, 1995 (60 FR 3583). That action proposed to require
modification of the electrical power installation of the flight data
recorder, replacement of the currently installed socket box for ground
power with a modified socket box, and performance of checks and tests.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.
The commenter requests that all references to the ``modified ground
power socket box'' be changed to read ``reworked ground power socket
box.'' The commenter states that the latter phrase is used in the
relevant service instructions, and considers that there will be less
potential for confusion if the terminology in the AD is parallel to
that in the service instructions. The FAA concurs. The terminology in
the final rule has been revised accordingly.
After careful review of the available data, including the comment
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the change previously
described. The FAA has determined that this change will neither
increase the economic burden on any operator nor increase the scope of
the AD.
The FAA estimates that 18 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 8 work hours per
airplane to accomplish the required actions, and that the average labor
rate is $60 per work hour. Required parts will cost approximately $286
per airplane. Based on these figures, the total cost impact of the AD
on U.S. operators is estimated to be $13,788, or $766 per airplane.
The total cost impact figure discussed above is 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 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.
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

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
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. 106(g), 40101, 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
95-19-16 Dassault Aviation: Amendment 39-9378. Docket 94-NM-200-AD.
Applicability: Model Mystere-Falcon 900 series airplanes having
serial numbers 53 through 139 inclusive, equipped with Fairchild
Model F800 flight data recorders, installed in accordance with
Supplemental Type Certificate (STC) SA7255SW-D; 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 (c) of this AD 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 loss of electrical power to the airplane due to
generator outage, accomplish the following:
(a) At the next scheduled inspection, but no later than 60 days
