2012-7372. Airworthiness Directives; DASSAULT AVIATION Airplanes  

  • Start Preamble

    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.

    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 Start Printed Page 19075information 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.
