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 certain Dassault Aviation Model FALCON 900EX airplanes and FALCON 2000EX airplanes. This proposed AD was prompted by a report of significant fuel leakage at the middle position of the left outboard slat. This proposed AD would require modifying the assembly of the slat extension mechanical stop. We are proposing this AD to prevent failure of the assembly of the slat extension mechanical stop, which if not corrected, could lead to a significant fuel leak and result in an uncontained fire.

DATES:

We must receive comments on this proposed AD by October 5, 2015.

ADDRESSES:

You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0115, dated May 13, 2014 (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 and FALCON 2000EX airplanes. The MCAI states:

After landing, an aeroplane experienced a significant fuel leakage at the middle position of the left outboard slat. Investigations showed that the fuel spillage originated in a structural cap, which had been punctured by a broken locking pin of the slat extension mechanical stop.

A design review revealed that the locking pin could become loose due to an incorrect installation combined with a non-fault-tolerant design.

This condition, if not corrected, may lead to a significant fuel leak, possibly resulting in an uncontained fire.

To address this potential unsafe condition, Dassault Aviation developed a modification of the slat extension mechanical stop assembly (Mod M3678 for F2000EX aeroplanes and Mod M5870 for F900EX aeroplanes) with the purpose to increase its robustness with regards to possible mishandling on production or during maintenance. Dassault Aviation also published Service Bulletin (SB) F2000EX-344 and SB F900EX-450, for embodiment in service of that modification.

For the reasons described above, this [EASA AD] requires modification of the slat extension mechanical stop assembly.

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-2015-3144.

Related Service Information Under 1 CFR Part 51

We reviewed Dassault Service Bulletin F900EX-450, dated March 10, 2014; and Service Bulletin F2000EX-344, dated March 10, 2014. This service information describes procedures for modifying the assembly of the slat extension mechanical stop. 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 of this NPRM.

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 67 airplanes of U.S. registry.

We also estimate that it would take about 8 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $3,510 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $280,730, or $4,190 per product.

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.

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.
