14 CFR Part 39


[Docket No. FAA-2005-22633; Directorate Identifier 2005-NM-155-AD; Amendment 39-14422;

Airworthiness Directives; Dassault Model Falcon 2000 Airplanes


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


ACTION:
 
Final rule.


–––––––––––––––––––––––––––––––––––


SUMMARY:
 
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model


Falcon 2000 airplanes. This AD requires 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 AD results from a report of a missing pin of a fail-safe fastener. We are issuing 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:
 
This AD becomes effective January 24, 2006.


The Director of the Federal Register approved the incorporation by reference of a certain


publication listed in the AD as of January 24, 2006.

SUPPLEMENTARY INFORMATION:


Examining the Docket


You may examine the airworthiness directive (AD) docket on the Internet at
 
http://dms.dot.gov


or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through


Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227)


is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES


section.


Discussion


The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include


an AD that would apply to certain Dassault Model Falcon 2000 airplanes. That NPRM was published


in the Federal Register on October 7, 2005 (70 FR 58634). That NPRM proposed to 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.


Comments


We provided the public the opportunity to participate in the development of this AD. We


received no comments on the NPRM or on the determination of the cost to the public.


Conclusion


We have carefully reviewed the available data and determined that air safety and the public


interest require adopting the AD as proposed.


Costs of Compliance


This AD will affect about 149 airplanes of U.S. registry. The required inspection will 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 required 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 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.
