# AGENCY:

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

# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 airplanes. This proposed AD would require an inspection for the presence of fail-safe pins, nuts, and washers on each engine, and replacement of the fail-safe fastener assembly with a new assembly if necessary. This proposed AD results from a report of a missing pin of a fail-safe fastener. We are proposing this AD to prevent reduced structural integrity of an engine mount due to a missing pin of a fail-safe fastener, and possible separation of an engine from the airplane during flight. 

# DATES:

We must receive comments on this proposed AD by November 7, 2005.

## Discussion 

The Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Dassault Model Falcon 2000 airplanes. The DGAC advises that the inner pin of a fail-safe fastener, which ensures the link between the rear of the engine and the fuselage, has been found missing on an in-service airplane. Lack of clarity in a production procedure is suspected to be the cause of this event. A missing pin of a fail-safe fastener, if not corrected, could result in reduced structural integrity of an engine mount, and possible separation of an engine from the airplane during flight. 

## Relevant Service Information 

Dassault has issued Service Bulletin F2000-301, dated February 2, 2005. The service bulletin describes procedures for a detailed inspection for the presence of fail-safe pins, nuts, and washers on each engine, and replacement of the fail-safe fastener assembly with a new assembly if necessary. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directive F-2005-018, dated February 2, 2005, to ensure the continued airworthiness of these airplanes in France. 

## FAA's Determination and Requirements of the Proposed AD 

This airplane model is manufactured in France and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC's findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. 

                    Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously,                           ( print page 58635)                        except as discussed under “Difference Between Proposed Rule, French Airworthiness Directive, and Referenced Service Bulletin.”                 

## Difference Between Proposed Rule, French Airworthiness Directive, and Referenced Service Bulletin 

The French airworthiness directive requires operators to inform the airplane manufacturer of inspection results. The Accomplishment Instructions of the referenced service bulletin describe procedures for submitting a comment sheet related to service bulletin quality, a sheet recording compliance with the service bulletin, and reply card noting the precise location of any missing component. However, this proposed AD would not require those actions. We do not need this information from operators. 

## Costs of Compliance 

This proposed AD would affect about 149 airplanes of U.S. registry. The proposed inspection would take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the inspection proposed by this AD for U.S. operators is $9,685, or $65 per airplane. 

## 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 have 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 that the 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); and 

3. 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. See the                     **ADDRESSES**                     section for a location to examine the regulatory evaluation.
