Airworthiness Directives; Cessna Model 500, 501, 550, 551, S550, 
560, 560XL, and 750 Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Cessna Model 500, 550, S550, 560, 560XL, 
and 750 airplanes. That AD currently requires installing identification 
sleeves on the wires for the positive and negative terminal studs of 
the engine and/or auxiliary power unit (APU) fire extinguishing 
bottles, as applicable, and re-connecting the wires to the correct 
terminal studs. This new AD retains the requirements of the existing 
AD; adds airplanes to the applicability; and, for certain airplanes 
only, requires a review of wiring changes made using the original issue 
of one service bulletin and corrective actions if necessary. This AD 
results from a determination that additional airplanes are subject to 
the unsafe condition described in the existing AD. We are issuing this 
AD to ensure that the fire extinguishing bottles are activated in the 
event of an engine or APU fire, and that flammable fluids are not 
supplied during a fire, which could result in an unextinguished fire in 
the nacelle or APU.

[[Page 30475]]


DATES: This AD becomes effective July 6, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of July 6, 2007.
    On March 24, 2006 (71 FR 8443, February 17, 2006), the Director of 
the Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.

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 supersedes AD 2006-04-10, amendment 
39-14491 (71 FR 8443, February 17, 2006). The existing AD applies to 
certain Cessna Model 500, 550, S550, 560, 560XL, and 750 airplanes. 
That NPRM was published in the Federal Register on February 15, 2007 
(72 FR 7357). That NPRM proposed to require installing identification 
sleeves on the wires for the positive and negative terminal studs of 
the engine and/or auxiliary power unit fire extinguishing bottles, as 
applicable, and re-connecting the wires to the correct terminal studs. 
That NPRM also proposed to retain the requirements of the existing AD; 
add airplanes to the applicability; and, for certain airplanes only, 
require a review of wiring changes made using the original issue of one 
service bulletin and corrective actions if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received 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

    There are about 3,801 airplanes of the affected design in the 
worldwide fleet, including about 3,071 airplanes of U.S. Registry. The 
following table provides the estimated costs for U.S. operators to 
comply with this AD, at an average labor rate of $80 per work hour.

                                                                     Estimated Costs

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.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

extinguishing bottles. We are issuing this AD to ensure that the 
fire extinguishing bottles are activated in the event of an engine

not supplied during a fire, which could result in an unextinguished 
fire in the nacelle or APU.
