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 MYSTERE-FALCON 900 and FALCON 900EX airplanes. This proposed AD was prompted by reports of chafing between the tail strobe power supply and a hydraulic line. This proposed AD would require modifying the tail strobe power supply wire routing. We are proposing this AD to prevent chafing between the tail strobe power supply and a hydraulic line, which could result in hydraulic fluid leakage and possible fire due to arcing, and consequent loss of control of the airplane due to structural failure of the tail.

DATES:

We must receive comments on this proposed AD by March 22, 2013.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012-0162, dated August 29, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

Two reports were received concerning Falcon 900 aeroplanes, where chafing between the tail strobe power supply and a hydraulic line was found. In the latest reported occurrence, the chafing damaged the power line and created an electrical arcing which created a pin hole in the hydraulic line, leading to hydraulic fluid leakage.

This condition, if not corrected, could jeopardize the aeroplane's safe flight.

To address this potential unsafe condition, Dassault Aviation developed modification (M5741) of the routing of the tail strobe power supply wire, which is available for accomplishment in service through Dassault Service Bulletin (SB) F900-431 or SB F900EX-437, as applicable to aeroplane model.

For the reasons described above, this [EASA] AD requires modification of the routing of the tail strobe power supply wire.

The unsafe condition is chafing between the tail strobe power supply and a hydraulic line, which could result in hydraulic fluid leakage and possible fire due to arcing, and consequent loss of control of the airplane due to structural failure of the tail. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Dassault has issued Mandatory Service Bulletin F900-431, dated November 8, 2011 (for Model MYSTERE-FALCON 900 airplanes); and Mandatory Service Bulletin F900EX-437, dated November 8, 2011 (for Model FALCON 900EX airplanes). The actions described in these service bulletins are intended to correct the unsafe condition identified in the MCAI.

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

Based on the service information, we estimate that this proposed AD would affect about 180 products of U.S. registry. We also estimate that it would take about 2 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 $31 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $36,180, or $201 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.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.
