FAA AD Differences
Note: This AD differs from the MCAI and/
or service information as follows:
(1) We believe that the batteries specified
in the MCAI do not fully address the unsafe
condition for U.S. registered airplanes. The
batteries specified in the MCAI only provide
approximately 10 minutes of backup
electrical power to the engine full authority
digital engine controls (FADECs) in the event
of an aircraft electrical failure. In accordance
with 14 CFR 23.1353(h), the FAA requires a
minimum of 30 minutes of backup electrical
power for the engine FADECs in the event of
an aircraft electrical failure. To fully address
the unsafe condition, Diamond Aircraft
Industries GmbH has developed different
part numbers and procedures for U.S.registered airplanes. These procedures
require the installation of larger capacity
batteries than the MCAI required. The
batteries specified in Diamond Aircraft
Industries GmbH Work Instruction WI–OSB–
42–050, Revision 2, dated September 10,
2007, will provide a minimum of 30 minutes
of backup electrical power for the engine
FADECs when installed in accordance with
Diamond Aircraft Industries GmbH Work
Instruction WI–OSB–42–050, Revision 2,
dated September 10, 2007. We have
discussed this difference with EASA, and
they accepted that the FAA’s view is
different to require installation of larger
capacity batteries.

SUPPLEMENTARY INFORMATION:
Discussion
Cessna issued Service Bulletin
SB525B–24–02, dated January 10, 2007,
to add fuses to the emergency electrical
power relay circuits to protect aircraft
wiring left unprotected in the original
design. Since issuance of that service
bulletin, the FAA received a report from
Cessna of a Model 525B airplane
experiencing an in-flight direct short
between aircraft direct current (DC)
power and ground with loss of
numerous systems, tripped circuit
breakers, and burned wiring adjacent to
the power distribution panel.
Cessna determined that a wiring
alteration done following Cessna
Citation Service Bulletin SB525B–24–
02, dated January 10, 2007, contributed
to this direct short between aircraft DC
power and ground. The service bulletin
had incorrect alteration instructions,
which if implemented, could cause a
VerDate Aug<31>2005
15:17 Nov 19, 2007
Jkt 214001
direct short between aircraft DC power
and ground.
Failure or opening of power bus
limiters in conjunction with
incorporation of that service bulletin
may result in loss of numerous systems
and burned aircraft wiring. The
instructions and wiring diagrams call
for incorrectly connecting 28V DC to an
annunciator panel where there should
be a ground. Terminal 2 of circuit
breaker HZ050 is left with no wiring
connected. This results in a direct short.
Cessna revised the service bulletin to
include correct alteration instructions
that would fully address the unsafe
condition of unprotected wiring in the
original design.
This condition, if not corrected, could
result in burned wiring and loss of
various aircraft electrical systems.
Relevant Service Information
We reviewed Cessna Citation Service
Bulletin SB525B–24–02, Revision 1,
dated October 4, 2007. The service
information describes procedures for
incorporating electrical power relay
circuit protection kit P/N SB525B–24–
02. The manufacturer intends that the
actions specified in the service
information adequately address the
unsafe condition.
FAA’s Determination and Requirements
of this AD
We are issuing this AD because we
evaluated all the information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This AD requires you to
incorporate electrical power relay
circuit protection kit P/N SB525B–24–
02.
In preparing this rule, we contacted
type clubs and aircraft operators to get
technical information and information
on operational and economic impacts.
We did not receive any information
through these contacts. If received, we
would have included a discussion of
any information that may have
influenced this action in the rulemaking
docket.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because this condition, if not
corrected, could result in burned wiring
and loss of various aircraft electrical
systems. Therefore, we determined that
notice and opportunity for public
comment before issuing this AD are
PO 00000
Frm 00006
Fmt 4700
Sfmt 4700
impracticable and that good cause exists
for making this amendment effective in
fewer than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and an
opportunity for public comment. We
invite you to send any written relevant
data, views, or arguments regarding this
AD. Send your comments to an address
listed under the ADDRESSES section.
Include the docket number ‘‘FAA–
2007–0198; Directorate Identifier 2007–
CE–085–AD’’ at the beginning of your
comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the AD. We will consider all
comments received by the closing date
and may amend the AD in light of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
concerning this AD.
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 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.
For the reasons discussed above, I
certify that this AD:
E:\FR\FM\20NOR1.SGM
20NOR1
Federal Register / Vol. 72, No. 223 / Tuesday, November 20, 2007 / Rules and Regulations

under the criteria of the Regulatory
Flexibility Act.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

Relevant Service Information
We reviewed Cessna Citation Service Bulletin SB525B-24-02, Revision
1, dated October 4, 2007. The service information describes procedures
for incorporating electrical power relay circuit protection kit P/N
SB525B-24-02. The manufacturer intends that the actions specified in
the service information adequately address the unsafe condition.
FAA's Determination and Requirements of this AD
We are issuing this AD because we evaluated all the information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This AD requires
you to incorporate electrical power relay circuit protection kit P/N
SB525B-24-02.
In preparing this rule, we contacted type clubs and aircraft
operators to get technical information and information on operational
and economic impacts. We did not receive any information through these
contacts. If received, we would have included a discussion of any
information that may have influenced this action in the rulemaking
docket.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because this
condition, if not corrected, could result in burned wiring and loss of
various aircraft electrical systems. Therefore, we determined that
notice and opportunity for public comment before issuing this AD are
impracticable and that good cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and an opportunity for
public comment. We invite you to send any written relevant data, views,
or arguments regarding this AD. Send your comments to an address listed
under the ADDRESSES section. Include the docket number ``FAA-2007-0198;
Directorate Identifier 2007-CE-085-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD. We will consider
all comments received by the closing date and may amend the AD in light
of those comments.
We will post all comments we receive, without change, to https://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive concerning this AD.
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 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.
For the reasons discussed above, I certify that this AD:
[[Page 65221]]
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the AD, the regulatory
evaluation, any comments received, and other information on the
Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2007-23-16 Cessna Aircraft Company: Amendment 39-15262; Docket No.
FAA-2007-0198; Directorate Identifier 2007-CE-085-AD.
Effective Date
(a) This AD becomes effective on December 19, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model 525B, serial numbers 0001 through
0013 airplanes, that are certificated in any category.
Unsafe Condition
(d) This AD results from both the need to protect aircraft
wiring left unprotected in the original design and a report of a
Model 525B airplane experiencing in-flight loss of numerous systems,
tripped circuit breakers, and burned wiring adjacent to the power
distribution panel. We are issuing this AD to correct an incorrect
wiring installation and to provide short-circuit protection for all
wiring from the aircraft power distribution system. This condition
could result in burned wiring and loss of various aircraft
electrical systems.
