14 CFR Part 39

[Docket No. FAA-2012-1322; Directorate Identifier 2012-NM-155-AD; 
Amendment 39-17466; AD 2013-11-06]
RIN 2120-AA64


Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Dassault Aviation Model Mystere-Falcon 900 and Falcon 900EX airplanes. 
This AD was prompted by reports of chafing between the tail strobe 
power supply and a hydraulic line. This AD requires modifying the tail 
strobe power supply wire routing. We are issuing 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: This AD becomes effective July 9, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 9, 2013.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION:

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 February 5, 2013 (78 
FR 8052). That NPRM proposed to correct an unsafe condition for the 
specified products. 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 8052, February 5, 
2013) 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--except for 
minor editorial changes. We have determined that these minor changes:

[[Page 33200]]

     Are consistent with the intent that was proposed in the 
NPRM (78 FR 8052, February 5, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 8052, February 5, 2013).

Costs of Compliance

    We estimate that this AD will affect 180 products of U.S. registry. 
We also estimate that it will take about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will 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 this AD to the 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 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 that 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);
    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 AD and placed it in the AD docket.
