Airworthiness Directives; Reims Aviation S.A. Model F406 Airplanes


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


ACTION:
 
Final rule.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are rescinding an existing airworthiness directive (AD) for the products listed


above. The existing AD resulted from mandatory continuing airworthiness information (MCAI)


issued by an aviation authority of another country to identify and correct an unsafe condition on an


aviation product. The MCAI describes the unsafe condition as:


On several occasions, leaks of the landing gear emergency blowdown bottle have been


reported. Investigations revealed that the leakage was located on the nut manometer


because of a design deficiency in the bottle head.


If left uncorrected, the internal bottle pressure could not be maintained to an adequate


level and could result in a malfunction, failing to extend landing gears during emergency


situations.


Since issuance of that AD, we have determined that the condition is not unsafe.


DATES:
 
This AD becomes effective December 4, 2009.

SUPPLEMENTARY INFORMATION:


Discussion


We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD


that would apply to the specified products. That NPRM was published in the Federal Register on July


31, 2009 (74 FR 38140), and proposed to rescind AD 2007-26-08, Amendment 39-15310 (72 FR


73258, December 27, 2007).


Since we issued AD 2007-26-08, we have reconsidered this AD with respect to the determination


of an unsafe condition.


We issued AD 2007-26-08 in consideration of the MCAI from an aviation authority of another


country to identify and correct an unsafe condition on an airplane. At that time, we were not aware


that there were several Cessna Aircraft Company (Cessna) model airplanes equipped with the same


blowdown bottle part number (P/N) 9910154-4.


Before issuing an AD on domestic products, we prepare a risk assessment of the unsafe


condition. A risk assessment was done for the Cessna model airplanes. The result of that assessment


was not high enough to support AD action since the system is a backup system to the primary landing


gear extension system.


Based on this risk assessment, we reevaluated the existing AD against Reims Aviation Model


406 airplanes (AD 2007-26-08) and determined the condition identified in the AD is not an unsafe


condition.


Comments


We gave the public the opportunity to participate in developing this AD. We received no


comments on the NPRM or on the determination of the cost to the public.


Conclusion


We reviewed the available data and determined that air safety and the public interest require


adopting the AD as proposed.


FAA's Determination and Requirements of the AD Rescission


We are issuing this AD rescission because we evaluated all information and determined the


condition identified in the existing AD is not unsafe and the AD is not necessary.


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.
