Federal Aviation Administration (FAA), Department of Transportation (DOT).
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX airplanes. This AD was prompted by reports of rejected take-offs due to untimely inboard flap retraction. This AD requires modification of the slat/flap control wiring and replacement of the slat/flap control box with an improved box. We are issuing this AD to address the unsafe condition on these products.
This AD is effective November 13, 2018.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 13, 2018.

Box 2000, South Hackensack, NJ 07606; telephone 201-440-6700; internet http://www.dassaultfalcon.com.

Start Supplemental Information
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Dassault Aviation Model FALCON 900EX airplanes. The NPRM published in the Federal Register on May 30, 2018 (83 FR 24686). The NPRM was prompted by reports of rejected take-offs due to untimely inboard flap retraction. The NPRM proposed to require modification of the slat/flap control wiring and replacement of the slat/flap control box with an improved box.
We are issuing this AD to address an uncommanded retraction of the inboard slats and flaps during take-off, and consequent reduced controllability of the airplane.
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.
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.
We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public.
We reviewed the relevant data and determined that air safety and the public interest require adopting this final rule 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 for addressing the unsafe condition; and
- Do not add any additional burden upon the public than was already proposed in the NPRM.
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.
Costs of Compliance
We estimate that this AD affects 13 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
|Action||Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Modification and replacement||22 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 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 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 Start Printed Page 50479Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.
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.
