Airworthiness Directives; Dassault Model Mystere-Falcon 50 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

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.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street, SW., Nassif Building, 
Room PL-401, Washington DC.

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 http://dms.dot.gov; 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.

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
