Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2005-21109; Directorate Identifier 2005-CE-21-AD; 
Amendment 39-14232; AD 2005-17-11]
RIN 2120-AA64


Airworthiness Directives; The Cessna Aircraft Company Models 525, 
525A, and 525B Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain 
The Cessna Aircraft Company (Cessna) Models 525, 525A, and 525B 
airplanes. This AD requires you to install identification sleeves on 
the wiring for both engine fire extinguisher bottles. This AD results 
from reports of incorrectly connecting wires to the engine fire 
extinguisher bottles. We are issuing this AD to prevent incorrect 
installation of the wires to the engine fire extinguisher bottles, 
which could result in failure of the engine fire extinguisher bottles 
to discharge when activated. This failure could lead to the inability 
to control an engine fire.

DATES: This AD becomes effective on October 7, 2005.
    As of October 7, 2005, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in the regulation.

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? Wires connected to the engine fire 
extinguisher bottles on Cessna Models 525B and 560XL airplanes were 
found reversed. Installing the wiring in an incorrect configuration 
resulted from a lack of clarity in the wiring schematics for connecting 
the wires and testing the connections.
    The same lack of clarity in the wiring schematics for connecting 
the wires and testing the connections also exists for Cessna Models 525 
and 525A airplanes.
    An incorrect wiring configuration installation could go undetected 
because the existing circuit checks appear normal during routine 
checks. However, the engine fire extinguisher bottles will not 
discharge when activated.
    What is the potential impact if FAA took no action? If not detected 
and corrected, incorrect wiring of the engine fire extinguisher bottles 
could result in failure of the engine fire extinguisher bottles to 
discharge when activated. This failure could lead to the inability to 
control an engine fire.
    Has FAA taken any action to this point? We issued a proposal to 
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to 
include an AD that would apply to certain Cessna Models 525, 525A, and 
525B airplanes. This proposal was published in the Federal Register as 
a notice of proposed rulemaking (NPRM) on May 19, 2005 (70 FR 28857). 
The NPRM proposed to require you to do the following:

--Install identification sleeves on wires connecting to the engine fire 
extinguisher bottles;
--Reconnect the wires to the engine fire extinguisher bottles; and
--Test the wiring for correct installation.

Comments

    Was the public invited to comment? We provided the public the 
opportunity to participate in developing this AD. We received no 
comments on the proposal or on the determination of the cost to the 
public.

Conclusion

    What is FAA's final determination on this issue? We have carefully 
reviewed the available data and determined that air safety and the 
public interest require adopting the AD as proposed except for minor 
editorial corrections. We have determined that these minor corrections:

--Are consistent with the intent that was proposed in the NPRM for 
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already 
proposed in the NPRM.

Changes to 14 CFR Part 39--Effect on the AD

    How does the revision to 14 CFR part 39 affect this AD? On July 10, 
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, 
July 22, 2002), which governs the FAA's AD system. This regulation now 
includes material that relates to altered products, special flight 
permits, and alternative methods of compliance. This material 
previously was included in each individual AD. Since this material is 
included in 14 CFR part 39, we will not include it in future AD 
actions.

Costs of Compliance

    How many airplanes does this AD impact? We estimate that this AD 
affects 578 airplanes in the U.S. registry.
    What is the cost impact of this AD on owners/operators of the 
affected airplanes? We estimate the following costs to do the 
modification:

----------------------------------------------------------------------------------------------------------------
                                                               Total cost
           Labor cost                     Parts cost          per airplane      Total cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
4 workhours x $65 per hour =      Not applicable............         $260   $260 x 578 = $150,280.
 $260.
----------------------------------------------------------------------------------------------------------------

    Cessna will provide warranty credit for the modification to the 
extent stated in the supplemental data to the service information.

Authority for This Rulemaking

    What authority does FAA have for issuing this rulemaking action? 
Title 49

[[Page 49168]]

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 AD.

Regulatory Findings

    Will this AD impact various entities? 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.
    Will this AD involve a significant rule or regulatory action? 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 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 summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2005-21109; Directorate Identifier 2005-CE-21-AD'' in your 
request.
