Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
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.
We must receive comments on this proposed AD by July 16, 2018.
You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

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:
|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 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.
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.

Air Transport Association (ATA) of America Code 27, Flight controls.
This AD was prompted by reports of rejected take-offs due to untimely inboard flap retraction. We are issuing this AD to prevent an uncommanded retraction of the inboard slats and flaps during take-off, and consequent reduced controllability of the airplane.
Comply with this AD within the compliance times specified, unless already done.Start Printed Page 24688
(g) Modification and Replacement
Within 500 flight hours after the effective date of this AD, modify the slat/flap control wiring and replace the slat/flap control box having part number (P/N) 6-7061 with an improved control box, in accordance with the Accomplishment Instructions of Dassault Aviation Service Bulletin F900EX-522, also referred to as 522, dated March 8, 2017.
(h) Parts Installation Prohibition
After modification of an airplane as required by paragraph (g) of this AD, no person may install any slat/flap control box having P/N 6-7061 on that airplane.
(i) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Section, Transport Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate.

Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Dassault Aviation's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
