[Docket No. FAA-2012-1322; Directorate Identifier 2012-NM-155-AD]
RIN 2120-AA64

Airworthiness Directives; DASSAULT AVIATION Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain DASSAULT AVIATION Model MYSTERE-FALCON 900 and FALCON 900EX 
airplanes. This proposed AD was prompted by reports of chafing between 
the tail strobe power supply and a hydraulic line. This proposed AD 
would require modifying the tail strobe power supply wire routing. We 
are proposing this AD to prevent chafing between the tail strobe power 
supply and a hydraulic line, which could result in hydraulic fluid 
leakage and possible fire due to arcing, and consequent loss of control 
of the airplane due to structural failure of the tail.

DATES: We must receive comments on this proposed AD by March 22, 2013.

ADDRESSES: You may send comments by any of the following methods:

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 2012-0162, dated August 29, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Two reports were received concerning Falcon 900 aeroplanes, 
where chafing between the tail strobe power supply and a hydraulic 
line was found. In the latest reported occurrence, the chafing 
damaged the power line and created an electrical arcing which 
created a pin hole in the hydraulic line, leading to hydraulic fluid 
leakage.
    This condition, if not corrected, could jeopardize the 
aeroplane's safe flight.
    To address this potential unsafe condition, Dassault Aviation 
developed modification (M5741) of the routing of the tail strobe 
power supply wire, which is available for accomplishment in service 
through Dassault Service Bulletin (SB) F900-431 or SB F900EX-437, as 
applicable to aeroplane model.
    For the reasons described above, this [EASA] AD requires 
modification of the routing of the tail strobe power supply wire.

The unsafe condition is chafing between the tail strobe power supply 
and a hydraulic line, which could result in hydraulic fluid leakage and 
possible fire due to arcing, and consequent loss of control of the 
airplane due to structural failure of the tail. You may obtain further 
information by examining the MCAI in the AD docket.

Relevant Service Information

    Dassault has issued Mandatory Service Bulletin F900-431, dated 
November 8, 2011 (for Model MYSTERE-FALCON 900 airplanes); and 
Mandatory Service Bulletin F900EX-437, dated November 8, 2011 (for 
Model FALCON 900EX airplanes). The actions described in these service 
bulletins 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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 180 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $31 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 parts. 
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 $36,180, or $201 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
