[Docket No. FAA-2007-27258; Directorate Identifier 2006-NM-213-AD]
RIN 2120-AA64
Airworthiness Directives; Cessna Model 500, 501, 550, 551, S550,
560, 560XL, and 750 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to certain Cessna Model 500, 550, S550,
560, 560XL, and 750 airplanes. The existing AD currently requires
installing identification sleeves on the wires for the positive and
negative terminal studs of the engine and/or auxiliary power unit (APU)
fire extinguishing bottles, as applicable, and re-connecting the wires
to the correct terminal studs. This proposed AD would retain the
requirements of the existing AD; add airplanes to the applicability;
and, for certain airplanes only, require a review of wiring changes
made using the original issue of one service bulletin and corrective
actions if necessary. This proposed AD results from a determination
that additional airplanes are subject to the unsafe condition described
in the existing AD. We are proposing this AD to ensure that the fire
extinguishing bottles are activated in the event of an engine or APU
fire, and that flammable fluids are not supplied during a fire, which
could result in an unextinguished fire in the nacelle or APU.
DATES: We must receive comments on this proposed AD by April 2, 2007.

Discussion
On February 7, 2006, we issued AD 2006-04-10, amendment 39-14491
(71 FR 8443, February 17, 2006), for certain Cessna Model 500, 550,
S550, 560, 560XL, and 750 airplanes. That AD requires installing
identification sleeves on the wires for the positive and negative
terminal studs of the engine and/or auxiliary power unit (APU) fire
extinguishing bottles, as applicable, and re-connecting the wires to
the correct terminal studs. That AD resulted from a report of mis-wired
fire extinguishing bottles. We issued that AD to ensure that the fire
extinguishing bottles are activated in the event of an engine or APU
fire, and that flammable fluids are not supplied during a fire, which
could result in an unextinguished fire in the nacelle or APU.
Actions Since Existing AD Was Issued
Since we issued AD 2006-04-10, we have determined that two affected
airplane models, Models 501 and 551, were not included in the
applicability of that AD. Model 501 and 551 airplanes could be subject
to the same unsafe condition as other airplanes subject to AD 2006-04-
10; therefore, we have added those airplanes to the applicability of
this proposed AD.
We have also determined that, as written, Cessna Service Bulletin
SB500-26-02, dated April 1, 2005, would not entirely correct the unsafe
condition. Therefore, any actions done using the original issue of the
service bulletin would not be considered acceptable for compliance with
the requirements of
[[Page 7358]]
this proposed AD, unless the actions are confirmed to be in accordance
with Revision 1 of the service bulletin, as described below.
Relevant Service Information
We have reviewed Cessna Service Bulletin SB500-26-02, Revision 1,
dated July 7, 2005, including Service Bulletin Supplemental Data, dated
April 1, 2005, which clarifies and corrects certain instructions and
wiring references in the text and Figure 1 of the original issue of the
service bulletin. Accomplishing the actions specified in the service
information is intended to adequately address the unsafe condition.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to develop on other airplanes of the
same type design. For this reason, we are proposing this AD, which
would retain the requirements of AD 2006-04-10; add airplanes to the
applicability; and, for certain airplanes only, require a review of
wiring changes made using Cessna Service Bulletin SB500-26-02, dated
April 1, 2005. This proposed AD would require accomplishing the actions
described previously, except as discussed under ``Difference Between
the Proposed AD and Service Bulletins.''
Difference Between the Proposed AD and Service Bulletins
Operators should note that, although the Accomplishment
Instructions of the referenced service bulletins describe procedures
for submitting a maintenance transaction report to the manufacturer,
this proposed AD would not require that action.
Costs of Compliance
There are about 3,801 airplanes of the affected design in the
worldwide fleet, including about 3,071 airplanes of U.S. Registry. The
following table provides the estimated costs for U.S. operators to
comply with this proposed AD, at an average labor rate of $80 per work
hour.

Authority for This Rulemaking
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
rulemaking action.
Regulatory Findings
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.
For the reasons discussed above, I certify that the proposed
regulation:
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 regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39

The Proposed Amendment
Accordingly, under the authority delegated to me by the

2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-14491 (71 FR 8443, February 17, 2006) and adding
the following new airworthiness directive (AD):

Unsafe Condition
(d) This AD results from a report of mis-wired fire
extinguishing bottles. We are issuing this AD to ensure that the
fire extinguishing bottles are activated in the event of an engine
or auxiliary power unit (APU) fire, and that flammable fluids are
not supplied during a fire, which could result in an unextinguished
fire in the nacelle or APU.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.

Cessna Service Bulletin SB500-26-02, dated April 1, 2005, conform to
the changes described in Cessna Service Bulletin SB500-26-02,
Revision 1, dated July 7, 2005; and, if any non-conforming wiring
changes are discovered, before further flight, correct the wiring
