AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain EMBRAER Model EMB–145XR
airplanes. This proposed AD would
require modification of the flap system
interface wiring. This proposed AD
results from a finding that the aural and
visual warnings, which should be
activated when the flaps are set to 22
degrees during takeoff, were not enabled
during the manufacture of certain Model
EMB–145XR airplanes. We are
proposing this AD to prevent
overrunning the runway during takeoff.

Discussion
The Departamento de Aviacao Civil
(DAC), which is the airworthiness
authority for Brazil, notified us that an
unsafe condition may exist on certain
EMBRAER Model EMB–145XR
airplanes. The Model EMB–145XR
airplane is not certified to takeoff with
the flaps set to 22 degrees; under this
condition, aural and visual warnings
should be activated to warn the
flightcrew. However, the DAC advises
that these aural and visual warnings
were not enabled during the
manufacture of certain airplanes. This
condition, if not corrected, could result
in an overrun of the runway during
takeoff.
Relevant Service Information
EMBRAER has issued Service Bulletin
145–27–0113, dated December 6, 2005.
The service bulletin describes
procedures for modifying the flap
system interface wiring. The
modification includes the following
steps:
• Installing and connecting diodes
CR0231 and CR0232 to splices SP4159,
SP4160, and SP4161.
• Disconnecting electrical wires
W101–4176–24, W101–4178–24, and
W101–4786–24 from electrical
connectors J0739 and J0741, and
rerouting and connecting them to
splices SP4160, SP4159, and SP4161,
respectively.
• Routing electrical wires W101–
5783–24, W101–5787–24, and W101–
5789–24 and connecting them to
electrical connectors J0739 and J0741.
The DAC mandated the service
information and issued Brazilian
airworthiness directive 2006–02–01,
dated February 24, 2006, to ensure the
continued airworthiness of these
airplanes in Brazil.
FAA’s Determination and Requirements
of the Proposed AD
This airplane model is manufactured
in Brazil and is type certificated for
operation in the United States under the
provisions of section 21.29 of the
PO 00000
Frm 00009
Fmt 4702
Sfmt 4702
19139
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Pursuant to
this bilateral airworthiness agreement,
the DAC has kept the FAA informed of
the situation described above. We have
examined the DAC’s findings, evaluated
all pertinent information, and
determined that we need to issue an AD
for airplanes of this type design that are
certificated for operation in the United
States.
Therefore, we are proposing this AD,
which would require accomplishing the
actions specified in the service
information described previously.
Costs of Compliance
This proposed AD would affect about
97 airplanes of U.S. registry. The
proposed actions would take about 5
work hours per airplane, at an average
labor rate of $80 per work hour.
Required parts would cost about $60 per
airplane. Based on these figures, the
estimated cost of the proposed AD for
U.S. operators is $44,620, or $460 per
airplane.
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;
E:\FR\FM\13APP1.SGM
13APP1
19140
Federal Register / Vol. 71, No. 71 / Thursday, April 13, 2006 / Proposed Rules
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.

Discussion
The Departamento de Aviacao Civil (DAC), which is the airworthiness
authority for Brazil, notified us that an unsafe condition may exist on
certain EMBRAER Model EMB-145XR airplanes. The Model EMB-145XR airplane
is not certified to takeoff with the flaps set to 22 degrees; under
this condition, aural and visual warnings should be activated to warn
the flightcrew. However, the DAC advises that these aural and visual
warnings were not enabled during the manufacture of certain airplanes.
This condition, if not corrected, could result in an overrun of the
runway during takeoff.
Relevant Service Information
EMBRAER has issued Service Bulletin 145-27-0113, dated December 6,
2005. The service bulletin describes procedures for modifying the flap
system interface wiring. The modification includes the following steps:
Installing and connecting diodes CR0231 and CR0232 to
splices SP4159, SP4160, and SP4161.
Disconnecting electrical wires W101-4176-24, W101-4178-24,
and W101-4786-24 from electrical connectors J0739 and J0741, and
rerouting and connecting them to splices SP4160, SP4159, and SP4161,
respectively.
Routing electrical wires W101-5783-24, W101-5787-24, and
W101-5789-24 and connecting them to electrical connectors J0739 and
J0741.
The DAC mandated the service information and issued Brazilian
airworthiness directive 2006-02-01, dated February 24, 2006, to ensure
the continued airworthiness of these airplanes in Brazil.
FAA's Determination and Requirements of the Proposed AD
This airplane model is manufactured in Brazil and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DAC has kept the FAA informed of
the situation described above. We have examined the DAC's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for airplanes of this type design that are certificated for
operation in the United States.
Therefore, we are proposing this AD, which would require
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
This proposed AD would affect about 97 airplanes of U.S. registry.
The proposed actions would take about 5 work hours per airplane, at an
average labor rate of $80 per work hour. Required parts would cost
about $60 per airplane. Based on these figures, the estimated cost of
the proposed AD for U.S. operators is $44,620, or $460 per airplane.
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;
[[Page 19140]]
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.

Sec. 39.13 [Amended]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Empresa Brasileira de Aeronautica S.A. (EMBRAER): Docket No. FAA-
2006-24439; Directorate Identifier 2006-NM-039-AD.
Comments Due Date
