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 all Dassault Aviation Model MYSTERE-FALCON 50 airplanes and FALCON 2000 airplanes. This proposed AD was prompted by a report indicating that during ground maintenance, a Model FALCON 2000 airplane experienced a loss of hydraulic pressure affecting both hydraulic systems due to damage to both brake hoses on the main landing gear (MLG). This proposed AD would require an inspection for certain brake hoses, installation of protective wraps or installation of certain brake hoses, and replacement of certain brake hoses. We are proposing this AD to address the unsafe condition on these products.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2013-0255, dated October 23, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Dassault Aviation Model MYSTERE-FALCON 50 airplanes and FALCON 2000 airplanes. The MCAI states:

During ground maintenance, a Falcon 2000 aeroplane experienced a loss of hydraulic pressure, affecting both hydraulic systems.

The investigation results revealed that this event was due to damage to both brake hoses on the same main landing gear (MLG), which chafed against the torque link assembly during MLG extension/retraction cycle. The Part Numbers (P/N) of the affected brake hoses are P/N AE705317-1 and P/N 00-200-1268, which are made of a braided stainless steel sleeve.

This condition, if not detected and corrected, could lead to loss of braking during landing or a rejected take-off, possibly resulting in a runway excursion. In addition, there is a risk of fire if the leaking brake hydraulic fluid reaches hot parts.

For the reasons described above, this [EASA] AD requires a one-time inspection of the brake hoses to identify the P/N and determine the presence of protection against chafing and, depending on findings, installation of protective wraps or replacement of the brake hoses with serviceable parts that have a Dacron sleeve protection.

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-2017-0130.

Related Service Information Under 1 CFR Part 51

Dassault has issued the following service information:

  • Dassault Service Bulletin F50-510, Revision 2, dated December 20, 2012; and Dassault Service Bulletin F2000-382, Revision 2, dated May 12, 2011. This service information describes procedures for an inspection of the brake hoses to identify whether brake hoses having certain part numbers are installed, and installation of protective wraps on the brake hoses or installation of certain brake hoses that are fitted with Dacron sleeves. These documents are distinct since they apply to different airplane models.
  • Dassault Service Bulletin F50-518, dated April 14, 2011; and Dassault Service Bulletin F2000-368, dated May 29, 2009. This service information describes replacement of certain brake hoses. 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.

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 these same type designs.

Costs of Compliance

We estimate that this proposed AD affects 302 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
Inspection1 work-hour × $85 per hour = $85$0$85$25,670

We estimate the following costs to do any necessary installations and replacements that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that might need these installations and replacements:

On-Condition Costs

ActionLabor costParts costCost per product
Installation of brake hose1 work-hour × $85 per hour = $85$340$425
Installation of protective wraps1 work-hour × $85 per hour = $85340425
Replacement1 work-hour × $85 per hour = $85340425

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.Start Printed Page 14834

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

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.
