You may also view the AD docket on the Internet at https://dms.dot.gov. The comments will be available in the AD docket shortly after the DMS receives them. Discussion What events have caused this proposed AD? Wires connected to the engine fire extinguisher bottles on Cessna Models 525B and 560XL airplane 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. Is there service information that applies to this subject? Cessna has issued the following service bulletins: —Citation Service Bulletin SB525–26– 01, dated April 5, 2005; —Citation Service Bulletin SB525A–26– 02, dated April 5, 2005; and —Citation Service Bulletin SB525B–26– 01, dated April 5, 2005. What are the provisions of this service information? These service bulletins include procedures for: —Installing identification sleeves on wires connecting to the engine fire extinguisher bottles; —Reconnecting the wires to the engine fire extinguisher bottles; and —Testing the wiring for correct installation. FAA’s Determination and Requirements of This Proposed AD What has FAA decided? We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. For this reason, we are proposing AD action. What would this proposed AD require? This proposed AD would E:\FR\FM\19MYP1.SGM 19MYP1 28858 Federal Register / Vol. 70, No. 96 / Thursday, May 19, 2005 / Proposed Rules require you to incorporate the actions in the previously-referenced service bulletin. How does the revision to 14 CFR part 39 affect this proposed AD? On July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs 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 would this proposed AD impact? We estimate that Total cost per airplane Labor cost Parts cost 4 workhours × $65 per hour = $260 ..................... Not applicable ............... 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 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 Would this proposed AD impact various entities? 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. this proposed AD affects 578 airplanes in the U.S. registry. What would be the cost impact of this proposed AD on owners/operators of the affected airplanes? We estimate the following costs to accomplish this proposed modification: $260.00 Total cost on U.S. operators $260 × 578 = $150,280. Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed 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 proposed 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 ‘‘AD Docket FAA–2005–21109; Directorate Identifier 2005–CE–21–AD’’ in your request.

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain The Cessna Aircraft Company (Cessna) Models 525, 525A, and 
525B airplanes. This proposed AD would require you to install 
identification sleeves on the wiring for both engine fire extinguisher 
bottles. This proposed AD results from reports of incorrectly 
connecting the wires to the engine fire extinguisher bottles. We are 
issuing this proposed 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.

in the AD docket shortly after the DMS receives them.

Discussion

    What events have caused this proposed AD? Wires connected to the 
engine fire extinguisher bottles on Cessna Models 525B and 560XL 
airplane 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.
    Is there service information that applies to this subject? Cessna 
has issued the following service bulletins:

--Citation Service Bulletin SB525-26-01, dated April 5, 2005;
--Citation Service Bulletin SB525A-26-02, dated April 5, 2005; and
--Citation Service Bulletin SB525B-26-01, dated April 5, 2005.

    What are the provisions of this service information? These service 
bulletins include procedures for:

--Installing identification sleeves on wires connecting to the engine 
fire extinguisher bottles;
--Reconnecting the wires to the engine fire extinguisher bottles; and
--Testing the wiring for correct installation.

FAA's Determination and Requirements of This Proposed AD

    What has FAA decided? We have evaluated all pertinent information 
and identified an unsafe condition that is likely to exist or develop 
on other products of this same type design. For this reason, we are 
proposing AD action.
    What would this proposed AD require? This proposed AD would

[[Page 28858]]

require you to incorporate the actions in the previously-referenced 
service bulletin.
    How does the revision to 14 CFR part 39 affect this proposed AD? On 
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 
47997, July 22, 2002), which governs 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 would this proposed AD impact? We estimate that 
this proposed AD affects 578 airplanes in the U.S. registry.
    What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to 
accomplish this proposed modification:

----------------------------------------------------------------------------------------------------------------
                                                                   Total cost per
              Labor cost                        Parts cost            airplane      Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
4 workhours x $65 per hour = $260.....  Not applicable...........         $260.00  $260 x 578 = $150,280.
----------------------------------------------------------------------------------------------------------------

    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 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

    Would this proposed AD impact various entities? 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.
    Would this proposed AD involve a significant rule or regulatory 
action? For the reasons discussed above, I certify that this proposed 
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 proposed AD 
(and other information as included in the Regulatory Evaluation) and
