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.
