AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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:

    Some occurrences have been reported where life rafts were 
difficult to remove from inside divan compartment. Investigations 
revealed that:

--Life raft was incorrectly stowed, with deployment straps inboard;
--Life raft had not been repacked to specified dimensions.
* * * * * * *
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2006-0366, dated December 11, 2006 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Some occurrences have been reported where life rafts were 
difficult to remove from inside divan compartment. Investigations 
revealed that:

--Life raft was incorrectly stowed, with deployment straps inboard;
--Life raft had not been repacked to specified dimensions

    The purpose of this Airworthiness Directive (AD) is to verify 
that all life rafts are stowed correctly with deployment straps 
outboard, and are repacked to specified dimensions.

Corrective actions include correctly reinstalling an incorrectly stowed 
life raft, installing a properly repacked life raft, and installing 
placards. You may obtain further information by examining the MCAI in 
the AD docket.

Relevant Service Information

    Dassault has issued Service Bulletin F50-480, dated December 5, 
2006. The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 25 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $68 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these costs. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $3,700, or $148 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 proposed AD and placed it in the AD docket.

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Dassault Aviation: Docket No. FAA-2007-0369; Directorate Identifier 
2007-NM-258-AD.

Comments Due Date

    (a) We must receive comments by January 22, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Dassault Model Mystere-Falcon 50 
airplanes, certificated in any category, serial numbers 294, 299, 
301 through 304, 306, 307, 310, 313, 314, 316 through 320, 322 
through 331, 334 through 337 and 339.

Subject

    (d) Air Transport Association (ATA) of America Code 25: 
Equipment/Furnishings.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    Some occurrences have been reported where life rafts were 
difficult to remove from inside divan compartment. Investigations 
revealed that:

--Life raft was incorrectly stowed, with deployment straps inboard;
--Life raft had not been repacked to specified dimensions

    The purpose of this Airworthiness Directive (AD) is to verify 
that all life rafts are stowed correctly with deployment straps 
outboard, and are repacked to specified dimensions.

Corrective actions include correctly reinstalling an incorrectly 
stowed life raft, installing a properly repacked life raft, and 
installing placards.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Within 10 flight cycles after the effective date of this AD: 
Verify that the life rafts are stowed correctly, with deployment 
straps outboard, in accordance with the instructions specified in 
Dassault Service Bulletin F50-480, dated December 5, 2006, and 
verify that the overall dimensions of the life raft hard pack do not 
exceed nominal values, as indicated in Part F50-480-1 of the service 
bulletin.
    (i) If a life raft is found incorrectly stowed, before next 
flight, reinstall it in accordance with the instructions specified 
in Part F50-480-1 of the service bulletin.
    (ii) If nominal values of the overall dimensions of the life 
raft hard pack are exceeded, within 3 months after the effective 
date of this AD, install a properly repacked life raft as instructed 
in Part F50-480-2 of the service bulletin.

    Note 1: Notice that with no life raft aboard, local national 
operating regulations may not allow some extended overwater flights.

    (2) Within 3 months after the effective date of this AD: Install 
placards on the sofa in accordance with the instructions specified 
in Part F50-480-2 of Dassault Service Bulletin F50-480, dated 
December 5, 2006.
