AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
*
*
*
*
*
[C]hafed wirings were found in the rear
baggage zone, closed [close] to the forward
side of the aft pressure bulkhead, due to
contact with an understructure securing
screw. The concerned wiring harness
includes rudder trim, pitch trim and stick
pusher control wires. Damages on those
wires might lead to the loss of fail safe
criteria for those critical functions.
*
*
*
*
*
The unsafe condition is reduced
controllability of the airplane. We are
issuing this AD to require actions to
correct the unsafe condition on these
products.
DATES: This AD becomes effective July
16, 2009.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of July 16, 2009.
ADDRESSES: You may examine the AD
docket on the Internet at https://
www.regulations.gov or in person at the
U.S. Department of Transportation,
Docket Operations, M–30, West
Building Ground Floor, Room W12–140,
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on November 26, 2008 (73 FR
71961). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
One ATR operator reported some spurious
‘‘Pitch disconnect’’ warning and ‘‘AIL and R
ELEV’’ Anti-Ice Horn Fault caution
annunciations which precluded the use of
the autopilot.
During the investigation, chafed wirings
were found in the rear baggage zone, closed
[close] to the forward side of the aft pressure
bulkhead, due to contact with an
understructure securing screw. The
concerned wiring harness includes rudder
trim, pitch trim and stick pusher control
wires. Damages on those wires might lead to
the loss of fail safe criteria for those critical
functions.
To address the identified unsafe condition,
this AD mandates a one-time inspection and
a routing modification of the electrical wires
in the bulkhead area.
The unsafe condition is reduced
controllability of the airplane. The
corrective action also includes
contacting ATR for repair instructions
and doing the repair if any damage
(chafing or contact between bundles of
cables and the airframe structure) is
found during the one-time inspection.
You may obtain further information by
examining the MCAI in the AD docket.
Explanation of Change to the NPRM
We have revised paragraph (c) of the
AD to coincide with the effectivity of
the European Aviation Safety Agency
(EASA) AD.

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
with the changes described previously.
We determined these changes will not
increase the economic burden on any
operator or increase the scope of the AD.
Differences Between This AD and the
MCAI or Service Information
cprice-sewell on PRODPC61 with RULES
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect
48 products of U.S. registry. We also
estimate that it will take about 5 workhours per product to comply with the
basic requirements of this AD. The
VerDate Nov<24>2008
14:23 Jun 10, 2009
Jkt 217001
average labor rate is $80 per work-hour.
Required parts will cost about $131 per
product. Where the service information
lists required parts costs that are
covered under warranty, we have
assumed that there will be no charge for
these parts. As we do not control
warranty coverage for affected parties,
some parties may incur costs higher
than estimated here. Based on these
figures, we estimate the cost of this AD
to the U.S. operators to be $25,488, or
$531 per product.
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 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 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 on
the Internet at https://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,
except Federal holidays. The AD docket
contains the NPRM, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647–5527) is in the ADDRESSES
section. Comments will be available in
the AD docket shortly after receipt.

doing other specified actions. This AD
results from an IFE systems review. We
are issuing this AD to ensure that the
flightcrew is able to turn off electrical
power to IFE systems and other nonessential electrical systems through a
switch in the flight compartment. The
flightcrew’s inability to turn off power
to IFE systems and other non-essential
electrical systems during a non-normal
or emergency situation could result in
the inability to control smoke or fumes
in the airplane flight deck or cabin.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
* * * * *
[C]hafed wirings were found in the rear baggage zone, closed
[close] to the forward side of the aft pressure bulkhead, due to
contact with an understructure securing screw. The concerned wiring
harness includes rudder trim, pitch trim and stick pusher control
wires. Damages on those wires might lead to the loss of fail safe
criteria for those critical functions.
* * * * *
The unsafe condition is reduced controllability of the airplane. We
are issuing this AD to require actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective July 16, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 16,
2009.
ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on November 26, 2008
(73 FR 71961). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states:
One ATR operator reported some spurious ``Pitch disconnect''
warning and ``AIL and R ELEV'' Anti-Ice Horn Fault caution
annunciations which precluded the use of the autopilot.
During the investigation, chafed wirings were found in the rear
baggage zone, closed [close] to the forward side of the aft pressure
bulkhead, due to contact with an understructure securing screw. The
concerned wiring harness includes rudder trim, pitch trim and stick
pusher control wires. Damages on those wires might lead to the loss
of fail safe criteria for those critical functions.
To address the identified unsafe condition, this AD mandates a
one-time inspection and a routing modification of the electrical
wires in the bulkhead area.
The unsafe condition is reduced controllability of the airplane. The
corrective action also includes contacting ATR for repair instructions
and doing the repair if any damage (chafing or contact between bundles
of cables and the airframe structure) is found during the one-time
inspection. You may obtain further information by examining the MCAI in
the AD docket.
Explanation of Change to the NPRM
We have revised paragraph (c) of the AD to coincide with the
effectivity of the European Aviation Safety Agency (EASA) AD.
Explanation of Revised Service Information
ATR has issued the service bulletins identified in the following
table.

------------------------------------------------------------------------
These service bulletins differ from the original issues of those
service bulletins, all dated February 11, 2008 (which were referenced
in the NPRM), by including clarifications and editorial changes that do
not affect the technical content. This AD does not require the
``Additional Work'' described in ATR Service Bulletins ATR42-92-0018
and ATR72-92-1018, both Revision 01, both dated September 4, 2008.
We have changed paragraphs (f)(1), (f)(2), and (f)(3) of this AD to
refer to the most recent revisions of the service bulletins identified
in the previous table, and added paragraph (f)(4) of this AD to give
credit for actions done according to the prior issues identified in the
following table.

Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD with the changes described
previously. We determined these changes will not increase the economic
burden on any operator or increase the scope of the AD.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect 48 products of U.S. registry.
We also estimate that it will take about 5 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $80 per work-hour. Required parts will cost about $131 per product.
Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these parts. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here. Based
on these figures, we estimate the cost of this AD to the U.S. operators
to be $25,488, or $531 per product.
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 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 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 on the Internet at https://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

211, ATR72-212, and ATR72-212A airplanes, all serial numbers except
serial numbers 756 and subsequent, and except airplanes on which ATR
Service Bulletin ATR72-92-1018 has been incorporated.
Subject
(d) Air Transport Association (ATA) of America Code 24:
Electrical power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
``One ATR operator reported some spurious ``Pitch disconnect''
warning and ``AIL and R ELEV'' Anti-Ice Horn Fault caution
annunciations which precluded the use of the autopilot.
``During the investigation, chafed wirings were found in the
rear baggage zone, closed [close] to the forward side of the aft
pressure bulkhead, due to contact with an understructure securing
screw. The concerned wiring harness includes rudder trim, pitch trim
and stick pusher control wires. Damages on those wires might lead to
the loss of fail safe criteria for those critical functions.
``To address the identified unsafe condition, this AD mandates a
one-time inspection and a routing modification of the electrical
wires in the bulkhead area.''
The unsafe condition is reduced controllability of the airplane. The
corrective action also includes contacting ATR for repair
instructions and doing the repair if any damage (chafing or contact
between bundles of cables and the airframe structure) is found
during the one-time inspection.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 550 flight hours after the effective date of this AD,

both Revision 01, both dated September 4, 2008.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information
as follows:
Although the MCAI or service information tells you to submit
information to the manufacturer, such submittal is not required by
this AD.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. Send information to ATTN: Tom
Rodriguez, Aerospace Engineer, 1601 Lind Avenue, SW., Renton,
Washington 98057-3356; telephone (425) 227-1137; fax (425) 227-1149.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
