2018-11422. Airworthiness Directives; Dassault Aviation Airplanes  

  • Start Preamble

    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 FALCON 900EX airplanes. This proposed AD was prompted by reports of rejected take-offs due to untimely inboard flap retraction. This proposed AD would require modification of the slat/flap control wiring and replacement of the slat/flap control box with an improved box. We are proposing this AD to address the unsafe condition on these products.

    DATES:

    We must receive comments on this proposed AD by July 16, 2018.

    Discussion

    The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017-0219, dated November 14, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Dassault Aviation Model FALCON 900EX airplanes. The MCAI states:

    An occurrence was reported where, during the take-off run, a red CAS [crew alerting system] message “NO TAKE OFF” was displayed, and an aural warning was given. The flight crew elected to abort the take-off. The configuration of the affected aeroplane was SF1 and indicated airspeed (IAS) was at 100 kts. Investigations showed that the outboard slat extended microswitch, located at track #7, was not correctly adjusted. A design review revealed that this deficiency may affect only Falcon 900LX (commercial designation) without modification M5636, during take-off in SF1 configuration.

    This condition, if not corrected, could lead to an uncommanded retraction of inboard slats and flaps during take-off, possibly resulting in reduced control of the aeroplane.Start Printed Page 24687

    To address this potential unsafe condition, DA [Dassault Aviation] designed modification M6043 and published Service Bulletin (SB) F900EX-522 to provide instructions for embodiment of this modification in-service.

    For the reasons described above, this [EASA] AD requires a wiring modification and replacement of the slat/flap control box with an improved box.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-0451.

    Related Service Information Under 1 CFR Part 51

    Dassault Aviation has issued Dassault Aviation Service Bulletin F900EX-522, also referred to as 522, dated March 8, 2017. This service information describes procedures for modifying the slat/flap control wiring and replacing the slat/flap control box. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

    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

    We estimate that this proposed AD affects 13 airplanes of U.S. registry.

    We estimate the following costs to comply with this proposed AD:

    Estimated Costs

    ActionLabor costParts costCost per productCost on U.S. operators
    Modification and replacement22 work-hours × $85 per hour = $1,870$8,495$10,365$134,745

    According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our cost estimate.

    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.

    This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division.

    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.
