[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 
ADDRESSES.

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:
