[Docket No. 97-NM-193-AD; Amendment 39-10395; AD 98-06-17]

Airworthiness Directives; Dassault Model Mystere Falcon 900 
Series Airplanes

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 replacement of the water heater control relays 
with improved relays having high-power contactors; the addition of a 
testing and monitoring circuit for each contactor; and installation of 
improved electrical bonding of the potable water tank. This amendment 
is prompted by issuance of mandatory continuing airworthiness 
information by a foreign civil airworthiness authority. The actions 
specified by this AD are intended to prevent overheating of the water 
heaters for the galley or the washbasin, which could result in damage 
to the water heater and nearby electrical wiring, and consequent smoke 
in the cabin.

DATES: Effective April 20, 1998.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of April 20, 1998.

ADDRESSES: The service information referenced in this AD may be 
obtained from Dassault Falcon Jet Corporation, Teterboro Airport, P.O. 
Box 2000, South Hackensack, New Jersey 07606. 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: Norman B. Martenson, Manager, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2110; fax (425) 227-1149.

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 was published in the Federal 
Register on January 5, 1998 (63 FR 171). That action proposed to 
require replacement of the water heater control relays with improved 
relays having high-power contactors; the addition of a testing and 
monitoring circuit for each contactor; and installation of improved 
electrical bonding of the potable water tank.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    The FAA estimates that 1 airplane of U.S. registry will be affected 
by this AD, that it will take approximately 24 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 $6,300 per 
airplane. Based on these figures, the cost impact of the AD on the 
single U.S. operator is estimated to be $7,740.
    The 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.

Regulatory Impact

    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

    Note 1: This AD applies to each airplane identified in the

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

alternative method of compliance in accordance with paragraph (b) 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 overheating of the water heaters for the galley or

potable water tank; in accordance with Dassault Service Bulletin 
F900-181 (F900-38-12), dated December 4, 1996.

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.

alternative methods of compliance with this AD, if any, may be 
obtained from the International Branch, ANM-116.

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 actions shall be done in accordance with Dassault 
Service Bulletin F900-181 (F900-38-12), dated December 4, 1996. This
