Rule

Airworthiness Directives; DASSAULT AVIATION Airplanes

Action

Final Rule.

Summary

We are adopting a new airworthiness directive (AD) for all DASSAULT AVIATION Model MYSTERE-FALCON 50 airplanes. This AD was prompted by reports of cracking of the flap tracks. This AD requires revising the maintenance program to include revised airworthiness limitations. We are issuing this AD to prevent cracking of the flap tracks, which could lead to flap asymmetry and loss of control of the airplane.

Discussion Back to Top

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 2, 2011 (76 FR 67633). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

The Maintenance Procedure (MP) 57-607, related to non destructive check of the flap tracks 2 and 5, has been introduced thru revision 4 (01/2009) of section 5-10 of the Recommended Maintenance Schedules chapter of the Aircraft Maintenance Documentation.

After the implementation of this MP cracks have been detected in service.

* * * * *

Cracking of the flap tracks could lead to flap asymmetry and loss of control of the airplane. The required actions include revising the maintenance program to include “Non-Destructive Check of Flap Tracks 2 and 5,” Maintenance Procedure 57-607, of Chapter 5-40, “Airworthiness Limitations,” of the Dassault Falcon 50/50EX Maintenance Manual, Revision 21, dated June 2011. You may obtain further information by examining the MCAI in the AD docket.

Comments Back to Top

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 67633, November 2, 2011) or on the determination of the cost to the public.

Explanation of Change Made to This AD Back to Top

We have revised the document citation for the service information referenced throughout this AD.

Conclusion Back to Top

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD with the change described previously—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 67633, November 2, 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 67633, November 2, 2011).

Costs of Compliance Back to Top

We estimate that this AD will affect 250 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $21,250, or $85 per product.

Authority for This Rulemaking Back to Top

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 Back to Top

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 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.

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 Back to Top

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 67633, November 2, 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.
