ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
* * * discovery of interferences between the power wire
supplying the galley's coffee-maker and the surrounding structure.
These interferences might, by chafing and degrading the wire
insulation, generate short circuits between the wire and the
aircraft ground through the composite cabinet structure, without
activation of the Circuit Breaker (C/B). Several hot spots may then
be created and generate a large amount of thick smokes just behind
the cockpit.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective July 16, 2007.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 16,
2007.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. This streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
safety risks to the public. This process continues to follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
unsafe conditions on U.S.-certificated products.
This AD references the MCAI and related service information that we
considered in forming the engineering basis to correct the unsafe
condition. The AD contains text copied from the MCAI and for this
reason might not follow our plain language principles.
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on April 9, 2007 (72 FR
17443). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
This Airworthiness Directive (AD) is issued following discovery
of interferences between the power wire supplying the galley's
coffee-maker and the surrounding structure. These interferences
might, by chafing and degrading the wire insulation, generate short
circuits between the wire and the aircraft ground through the
composite cabinet structure, without activation of the Circuit
Breaker (C/B). Several hot spots may then be created and generate a
large amount of thick smokes just behind the cockpit.
This AD aims to prevent this kind of incident, mandating a wire
inspection [for damaged wire sleeves], a check for a proper
clearance and if necessary a wire re-routing.
[[Page 31983]]
The MCAI also requires disabling the galley's coffee-maker, and, in
addition to wire re-routing, any required corrective actions.
(Corrective actions include replacing worn or defective wire sleeves
and shortening wires.) You may obtain further information by examining
the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a Note within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD will
affect about 44 products of U.S. registry. We also estimate that it
will take about 46 work-hours per product to comply with the basic
requirements of this AD. The average labor rate is $80 per work-hour.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $161,920, or $3,680 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD 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.
For the reasons discussed above, I certify this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at <a href="http://dms.dot.gov">http://dms.dot.gov</a>; or in person at the Docket Management Facility between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains the NPRM, the regulatory evaluation, any comments
received, and other information. The street address for the Docket
Office (telephone (800) 647-5227) is in the ADDRESSES section. Comments
will be available in the AD docket shortly after receipt.

Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2007-12-12 Dassault Aviation: Amendment 39-15090. Docket No. FAA-
2007-27806; Directorate Identifier 2006-NM-287-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective July 16,
2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Dassault Model Mystere-Falcon 50
airplanes; certificated in any category; with serial number 275
through 293 and 295 through 303 and 305 through 330 inclusive, with
the exception of airplanes which have already embodied the Dassault
Service Bulletin F50-456.
Subject
(d) Electrical Power; Equipment/Furnishings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
This Airworthiness Directive (AD) is issued following discovery
of interferences between the power wire supplying the galley's
coffee-maker and the surrounding structure. These interferences
might, by chafing and degrading the wire insulation, generate short
circuits between the wire and the aircraft ground through the
composite cabinet structure, without activation of the Circuit
Breaker (C/B). Several hot spots may then be created and generate a
large amount of thick smokes just behind the cockpit.
This AD aims to prevent this kind of incident, mandating a wire
inspection [for damaged wire sleeves], a check for a proper
clearance and if necessary a wire re-routing.
The MCAI also requires disabling the galley's coffee-maker, and, in
addition to wire re-routing, any required corrective actions.
(Corrective actions include replacing worn or defective wire sleeves
and shortening wires.)
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 50 flight hours or 1 month after the effective date
of this AD, whichever occurs first, disable the galley's coffee-
maker by pulling and locking out the circuit breaker 710HG, as
instructed in Dassault Service Bulletin F50-471, dated October 25,
2006.
(2) Within 1,530 flight hours or 24 months after the effective
date of this AD, whichever occurs first, inspect for damaged wire
sleeves, check their proper clearance, and if a discrepancy is
found, prior to next flight, proceed to do all applicable corrective
actions as indicated in the Accomplishment Instructions of Dassault
Service Bulletin F50-456, dated October 25, 2006. Doing the actions
specified in this paragraph terminates the requirements of paragraph
(f)(1) of this AD, and after the actions have been done, the circuit
breaker collar required by paragraph (f)(1) of this AD may be
removed.
[[Page 31984]]
FAA AD Differences
Note: This AD differs from the MCAI and/ or service information
as follows: The MCAI does not indicate that doing the actions
specified in Dassault Service Bulletin F50-456, dated October 25,
2006, terminates the requirement to disable the coffee-maker. This
AD indicates that doing the actions specified in Dassault Service
Bulletin F50-456 terminates the requirements to disable the coffee-
maker, and after the actions have been done, the circuit breaker
collar may be removed.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. Send information to ATTN: Tom
Rodriguez, Aerospace Engineer, 1601 Lind Avenue, SW., Renton,
Washington 98057-3356, telephone (425) 227-1137; fax (425) 227-1149.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
