[Docket No. FAA-2005-20438; Directorate Identifier 2005-CE-03-AD; 
Amendment 39-14147; AD 2005-13-10]
RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft Company Models 172R, 
172S, 182T, T182T, 206H, and T206H Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain 
Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, T182T, 206H, 
and T206H airplanes. This AD requires you to inspect any MC01-3A I.C. 9 
or MC01-3A I.C. 10 main electrical power junction box circuit breakers 
for correct amperage (amp) (a correct 40-amp circuit breaker) and 
replace any incorrect amp circuit breaker with the correct 40-amp 
circuit breaker. This AD results from several reports of circuit 
breakers that are not the correct 40-amp circuit breaker installed in 
the MC01-3A main electrical power junction box. We are issuing this AD 
to replace any incorrect circuit breaker installed in the MC01-3A I.C. 
9 or MC01-3A I.C. 10 main electrical power junction box, which could 
result in premature tripping of the power junction box main feeder 
circuit breakers and could lead to partial or complete loss of all 
electrical power on the airplane. This condition could lead to the loss 
of all navigation and communication equipment and lighting in the 
cockpit.

DATES: This AD becomes effective on August 9, 2005.
    As of August 9, 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? Cessna has reported three cases of 
incorrect amperage (amp) circuit breakers installed in the MC01-3A I.C. 
9 (part number (P/N) S3100-297) or MC01-3A I.C. 10 (P/N S3100-344) main 
electrical power junction box. The design of the main electrical power 
junction box requires 40-amp circuit breakers. Two of the three cases 
of incorrect circuit breakers were found in Cessna production and a 
third was found in Cessna spares.
    What is the potential impact if FAA took no action? Any incorrect 
circuit breaker installed in the MC01-3A main electrical power junction 
box could result in premature tripping of the power junction box main 
feeder circuit breakers, which could lead to partial or complete loss 
of all electrical power on the airplane. This condition could lead to 
the loss of all navigation and communication equipment and lighting in 
the cockpit.
    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 Aircraft Company 
(Cessna) Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. 
This proposal was published in the Federal Register as a notice of 
proposed rulemaking (NPRM) on March 17, 2005 (70 FR 12978). The NPRM 
proposed to require you to inspect any MC01-3A I.C. 9 or MC01-3A I.C. 
10 main electrical power junction box circuit breakers for correct 
amperage (amp) (a correct 40-amp circuit breaker) and replace any 
incorrect amp circuit breaker with the correct 40-amp circuit breaker.

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.

Docket Information

    Where can I go to view the docket information? You may view the AD 
docket that contains information relating to this subject in person at 
the DMS Docket Offices between 9 a.m. and 5 p.m. (eastern standard 
time), Monday through Friday, except Federal holidays. The Docket 
Office (telephone 1-800-647-5227) is located on the plaza level of the 
Department of Transportation NASSIF Building at the street address 
stated in ADDRESSES. You may also view the AD docket on the Internet at 
http://dms.dot.gov.

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 778 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 
inspection:

----------------------------------------------------------------------------------------------------------------
                                                               Total cost per
             Labor cost                      Parts cost           airplane       Total cost on  U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work hour x $65 = $65.............  None...................             $65  778 x $65 = $50,570.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of this inspection. We have 
no way of determining the number of airplanes that may need this 
replacement:

------------------------------------------------------------------------
                                                          Total cost per
               Labor cost                   Parts cost       airplane
------------------------------------------------------------------------
1 work hour x $65 = $65.................             $40            $105
------------------------------------------------------------------------

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

    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.

[[Page 35999]]

    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-2005-20438; Directorate Identifier 2005-CE-03-AD'' in your 
request.
