AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted by reports of a loose screw on certain slat mechanical stop assemblies, and punctures in certain fuel caps. This AD requires a one-time inspection, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective April 11, 2018.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 11, 2018.

SUPPLEMENTARY INFORMATION:

Discussion

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 MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The NPRM published in the Federal Register on October 24, 2017 (82 FR 49149) (“the NPRM”). The NPRM was prompted by reports of a loose screw on certain slat mechanical stop assemblies, and punctures in certain fuel caps. The NPRM proposed to require a one-time general visual inspection of the screw on the affected slat tracks, and replacement if necessary. We are issuing this AD to detect and correct loose screws that could lead to structural damage to the wing front spar, and consequent fuel leakage, possibly resulting in an uncontrolled fire.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0106, dated June 19, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The MCAI states:

On some aeroplanes in-service, the screw of the slat mechanical stop assembly on slat tracks #6, #7 and #8 was found loose. In some cases, a puncture was found in the fuel cap. The results of the technical investigations concluded that the most probable reason for these events was improper installation of the lock washers on the screws during production or maintenance.

This condition, if not detected and corrected, could lead to structural damage to the wing front spar, and consequent fuel leakage, possibly resulting in an uncontrolled fire.

To address this potential unsafe condition, Dassault issued [Service Bulletin] SB F900-460 Revision 1, SB F900EX-508 Revision 3, SB F2000-433 Revision 1, and SB F2000EX-386 Revision 3 (hereafter collectively referred as `the applicable SB' in this [EASA] AD), as applicable to aeroplane type/model, to provide inspection instructions.

For the reasons described above, this [EASA] AD requires a one-time [general visual] inspection of the slat tracks #6, #7 and #8 to verify the tightening torque of the screw and proper lock washer installation and, depending on findings, accomplishment of applicable corrective action(s).

Applicable corrective actions include replacement, if necessary. 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-2017-0909.

Comments

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.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed, except for minor changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.Start Printed Page 9684

Related Service Information Under 1 CFR Part 51

Dassault Aviation has issued the following service information.

  • Dassault Service Bulletin F900-460, Revision 1, dated February 10, 2017.
  • Dassault Service Bulletin F900EX-508, Revision 3, dated February 10, 2017.
  • Dassault Service Bulletin F2000-433, Revision 1, dated February 10, 2017.
  • Dassault Service Bulletin F2000EX-386, Revision 3, dated February 10, 2017.

This service information describes procedures for doing a one-time general visual inspection of the screw on the affected slat tracks, and replacement if necessary. These documents are distinct since they apply to different airplane models. 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 65 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspection4 work-hours × $85 per hour = $340$0$340$22,100

We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need this replacement:

On-Condition Costs

ActionLabor costParts costCost per product
Replacement6 work-hours × $85 per hour = $510$15$525

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 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 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.
