14 CFR Part 39

[Docket No. FAA-2005-20438; Directorate Identifier 2005-CE-03-AD]
RIN 2120-AA64

Airworthiness Directives; Cessna Aircraft Company Models 172R,
172S, 182T, T182T, 206H, and T206H 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 Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T,
T182T, 206H, and T206H airplanes. This proposed AD would 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. This proposed 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 proposed 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 failure could lead to the loss of all navigation and communication
equipment and lighting in the cockpit.

DATES: We must receive any comments on this proposed AD by May 16,
2005.

AD:

Discussion

What events have caused this proposed 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 failure could lead to the
loss of all navigation and communication equipment and lighting in the
cockpit.
Is there service information that applies to this subject? Cessna
has issued Service Bulletin No. SB05-24-01, dated January 31, 2005.
What are the provisions of this service information? The service
bulletin includes procedures for:

--Inspecting any MC01-3A I.C. 9 or MC01-3A I.C. 10 main electrical
power junction box circuit breakers for any circuit breaker that is not
a required 40-amp circuit breaker; and
--Replacing any incorrect circuit breaker with the correct 40-amp
circuit breaker.

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 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 778 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
do this proposed 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 proposed
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.

[[Page 12980]]

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

List of Subjects in 14 CFR Part 39

The Proposed Amendment

Accordingly, under the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend 14
CFR part 39 as follows:

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

What Is the Unsafe Condition Presented in This AD?

(d) This AD is the result of several reports of circuit breakers
that are not the correct 40-amp circuit breaker installed in the
MC01-3A I.C. 9 or MC01-3A I.C. 10 main electrical power junction
box. The actions specified in this AD are intended to replace any
incorrect circuit breaker installed in the MC01-3A 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 failure could lead to the loss of all navigation and
communication equipment and lighting in the cockpit.
