ACTION: Notice of proposed rulemaking (NPRM). AGENCY: 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 erjones on PRODPC74 with PROPOSALS SUMMARY: VerDate Aug<31>2005 14:53 Feb 14, 2007 Jkt 211001 are subject to the unsafe condition described in the existing AD.

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 E:\FR\FM\15FEP1.SGM 15FEP1 7358 Federal Register / Vol. 72, No. 31 / Thursday, February 15, 2007 / Proposed Rules 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. ESTIMATED COSTS Cessna Model Action 500, 550, S550, and 560 airplanes (action required by AD 2006–04–10). 560XL airplanes (action required by AD 2006–04–10). 750 airplanes (action required by AD 2006–04–10). 501 and 551 airplanes (action required by this proposed AD). 500 airplanes (action required by this proposed AD).

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.

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.

receives them.

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

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    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):

Cessna Aircraft Company: Docket No. 2007-27258; Directorate 
Identifier 2006-NM-213-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by April 2, 
2007.

Affected ADs

    (b) This AD supersedes AD 2006-04-10.

[[Page 7359]]

Applicability

    (c) This AD applies to Cessna Model 500, 501, 550, 551, S550, 
560, 560XL, and 750 airplanes, certificated in any category; as 
identified in the service bulletins specified in Table 1 of this 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.

Requirements of AD 2006-04-10
