[Docket No. 97-NM-193-AD; Amendment 39-10395; AD 98-06-17]
RIN 2120-AA64
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,

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

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 request approval for an
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
the washbasin, which could result in damage to the water heater and
nearby electrical wiring, and consequent smoke in the cabin,
accomplish the following:
(a) Within 7 months or 330 flight hours after the effective date
of this AD, whichever occurs first: Replace the water heater control
relays with improved relays; add a testing and monitoring circuit

F900-181 (F900-38-12), dated December 4, 1996.
(b) 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.

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
