14 CFR Part 39

[Docket No. FAA-2011-1164; Directorate Identifier 2011-NM-084-AD; 
Amendment 39-17002; AD 2012-06-21]

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 all 
DASSAULT AVIATION Model MYSTERE-FALCON 900 airplanes. This AD was 
prompted by multiple reports of fuel leakage from a defective fuel 
high-level sensor located in the wing front spar. This AD requires 
inspecting to determine fuel quantity sensors part numbers and 
replacing of certain fuel quantity sensors with new fuel quantity 
sensors. We are issuing this AD to prevent internal fuel leakage with 
significant fuel vapors, which could result in a fire hazard.

DATES: This AD becomes effective May 4, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 4, 2012.

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 November 4, 2011 (76 
FR 68368). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Several Mystere-Falcon 900 aeroplanes experienced fuel leakage 
from a defective fuel high-level sensor located in the wing front 
spar.
    Investigations revealed that the leakage was due to a defective 
fuel quantity sensor Part Number (P/N) 722105-2.
    This condition, if not detected and corrected, could lead to an 
internal fuel leakage with significant fuel vapours, which could 
result in a fire hazard.
    To address this unsafe condition, Dassault Aviation have 
developed an improved fuel quantity sensor with a new concept of 
sealing.
    For the reasons described above, this [EASA] AD requires the 
identification of the affected sensors and replacement with the 
improved part.

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 (76 FR 68368, November 4, 
2011) 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:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 68368, November 4, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 68368, November 4, 2011).

Costs of Compliance

    We estimate that this AD will affect 110 products of U.S. registry. 
We also estimate that it will take about 4 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 $4,000 per 
product. Where the service

[[Page 19075]]

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 $477,400, or 
$4,340 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (76 FR 68368, November 4, 
2011), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.
