ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER airplane models as identified above. This AD requires modifying the total air temperature (TAT) sensor heating system. This AD also allows replacing the fully automated digital electronic control (FADEC) assemblies with new or modified assemblies as an additional means of compliance. This AD results from a report indicating that the FADEC unit failed to compensate for ice accretion on the engine fan blades due to a false temperature signal from the TAT sensor to the FADEC. We are issuing this AD to prevent failure of the TAT sensor, which could result in E:\FR\FM\26OCR1.SGM 26OCR1 61730 Federal Register / Vol. 70, No. 206 / Wednesday, October 26, 2005 / Rules and Regulations insufficient thrust to take off or (if coupled with the loss of an engine during takeoff) to abort the takeoff in a safe manner, and consequent reduced controllability of the airplane. DATES: This AD becomes effective November 30, 2005. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of November 30, 2005. ADDRESSES: You may examine the AD docket on the Internet at https:// dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, room PL–401, Washington, DC.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the AD docket on the Internet at https://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain EMBRAER Model EMB–135BJ, –135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. That supplemental NPRM was published in the Federal Register on August 17, 2005 (70 FR 48339). That supplemental NPRM proposed to require modifying the total air temperature (TAT) sensor heating system. That supplemental NPRM also allows for replacing the fully automated digital electronic control (FADEC) unit assemblies with new or modified assemblies as an additional means of compliance. New Relevant Service Information EMBRAER has issued Service Bulletin 145–30–0028, Revision 10, dated March 22, 2005. Paragraph (f) of the supplemental NPRM refers to EMBRAER Service Bulletin 145–30– 0028, Revision 09, dated March 1, 2004, as the appropriate source of service information for modifying the TAT sensor heating system. The applicability statement of the supplemental NPRM also refers to EMBRAER Service Bulletin 145–30–0028, Revision 09, as the source in which affected airplanes are identified. Revision 10 of the service bulletin includes minor editorial revisions, but no substantive changes. Therefore, we have revised the applicability statement and paragraph (f) of this AD to refer to EMBRAER Service Bulletin 145–30–0028, Revision 10. We have also revised paragraph (g) of this AD to give credit for modifications done before the effective date of this AD in accordance with Revision 09. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Support for the Supplemental NPRM One commenter supports the intent of the supplemental NPRM. Request To Add Additional Means of Compliance The airplane manufacturer comments that it has recently approved FADEC software version 8.0. (Paragraph (h) of the supplemental NPRM specifies that replacing the existing FADEC assemblies with new or modified FADEC assemblies that include software version 7.6 is acceptable for compliance with paragraph (f) of the supplemental NPRM.) The commenter notes that, because the same features relating to temperature reading in FADEC software version 7.6 are included in software version 8.0, FADEC software version 8.0 should also be referenced as an acceptable means of compliance with the proposed requirements. The commenter also lists the service bulletins for installing FADEC software version 8.0. We agree with the commenter’s request. EMBRAER has issued the service bulletins specified in the table below. Service Information for Installing FADEC Assemblies Having Software Version 8.0 For EMBRAER Model— EMBRAER Service Bulletin Revision Date Which refers to Rolls-Royce Service Bulletin— EMB–135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, –145EP.

These service bulletins describe procedures for replacing existing FADEC assemblies with FADEC assemblies that have software version 8.0, including verifying the part number VerDate Aug<31>2005 14:58 Oct 25, 2005 Jkt 208001 of the ITT trim plug and replacing it with an ITT trim plug of another part number if necessary. These service bulletins also refer to the Rolls-Royce service bulletins listed in the table PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 above as additional sources of service information for replacing the FADEC assemblies. The EMBRAER service bulletins listed in the table also specify that installing the new or modified E:\FR\FM\26OCR1.SGM 26OCR1 61731 Federal Register / Vol. 70, No. 206 / Wednesday, October 26, 2005 / Rules and Regulations FADEC assemblies that have FADEC software version 8.0 also necessitates upgrading the engine indication and crew alerting system (EICAS), central maintenance computer (CMC), and IC– 600 configuration modules, as applicable. We have revised paragraph (h) and Table 2 of this AD to include references to these service bulletins and the applicable actions in them. Request To Add Reference to RollsRoyce Service Bulletins One commenter requests that we revise Table 2 of the supplemental NPRM to give credit for replacing the FADEC assemblies with new or modified FADEC assemblies that include software version 7.6 in accordance with Rolls-Royce Service Bulletin AE3007A–73–067 or AE3007A–73–069, as applicable. The commenter states that adding these service bulletins to Table 2 would save it a lot of time that would otherwise be needed to request an Alternative Method of Compliance (AMOC) and would save the FAA time that would be needed to address those AMOCs. We do not agree that any change to this AD is necessary to meet the intent of the commenter’s request. Table 2 of this AD gives credit for replacing FADEC assemblies with new or modified FADEC assemblies that include software version 7.6 in accordance with, among other service bulletins, EMBRAER Service Bulletin 145–73–0022 or 145–73–0024, both Revision 01, both dated July 15, 2004. We explain in the preamble of the supplemental NPRM that these EMBRAER Service Bulletins refer to Rolls-Royce Service Bulletin AE3007A– 73–067 and AE3007A–73–069, respectively, as additional sources of service information for replacing the FADEC assemblies. We find that doing the actions specified in Rolls-Royce Service Bulletin AE3007A–73–067 or AE3007A–73–069 is acceptable for compliance with the corresponding actions required by paragraph (h) of this AD, provided that all applicable EICAS, CMC, and IC–600 upgrades; as well as any other applicable actions associated with upgrading the EICAS, CMC, or IC– 600; are also done, as specified in paragraph 1.C., ‘‘Description—Time for Accomplishment,’’ of EMBRAER Service Bulletin 145–73–0022 or 145– 73–0024, both Revision 01, as required by paragraph (h) of this AD. No change to the AD is needed in this regard. Clarification of AMOC Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD. ESTIMATED COSTS Action Work hours Modify the TAT sensor heating system .................... For airplanes modified in accordance with Revisions 04 through 08 of EMBRAER Service Bulletin 145–30– 0028, it will take about 1 work hour per airplane to do the additional modification specified in Part III of the Accomplishment Instructions of the service bulletin, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of doing this required action is $65 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 VerDate Aug<31>2005 14:58 Oct 25, 2005 Jkt 208001 Average labor rate per hour 8 $65 Cost per airplane Parts $443 Number of U.S.registered airplanes $963 434 Fleet cost Up to $417,942. 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. 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. See the ADDRESSES section for a location to examine the regulatory evaluation. Regulatory Findings List of Subjects in 14 CFR Part 39 We have 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: (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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

[FR Doc. 05–21310 Filed 10–25–05; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 71 AGENCY: History On July 6, 2005, the FAA published in the Federal Register a notice of proposed rulemaking to establish four RITTR’s in the Cincinnati, OH, terminal area (70 FR 38826). Interested parties were invited to participate in this rulemaking effort by submitting written comments on this proposal to the FAA. Two comments were received in response to the NPRM. SUMMARY: This action establishes three Area Navigation Instrument Flight Rules Terminal Transition Routes (RITTR) in the Cincinnati, OH, terminal area. The FAA originally proposed to establish four routes as part of this action, but one route (T–212) was deleted because it did not meet RITTR design criteria and its short length would provide limited benefits. RITTR’s are low altitude Air Traffic Service (ATS) routes, based on Area Navigation (RNAV), for use by aircraft having Instrument Flight Rules (IFR)-approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. The FAA is taking this action to enhance safety and facilitate the more flexible Analysis of Comments The Aircraft Owners and Pilots Association wrote in support of the proposal. The second commenter expressed general support for the concept of terminal transition routes to assist IFR traffic transitioning Class B airspace, but stated that the proposed Cincinnati RITTRs do not accomplish this, and that IFR traffic (usually general aviation flights) would continue to be forced to make long detours around the Class B airspace. The commenter recommended that the FAA design transition routes that extend diagonally (northwest to southeast and southwest to northeast) across the Cincinnati/ Northern Kentucky International Airport (CVG) Class B airspace area.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain EMBRAER airplane models as identified above. This AD requires
modifying the total air temperature (TAT) sensor heating system. This
AD also allows replacing the fully automated digital electronic control
(FADEC) assemblies with new or modified assemblies as an additional
means of compliance. This AD results from a report indicating that the
FADEC unit failed to compensate for ice accretion on the engine fan
blades due to a false temperature signal from the TAT sensor to the
FADEC. We are issuing this AD to prevent failure of the TAT sensor,
which could result in

[[Page 61730]]

insufficient thrust to take off or (if coupled with the loss of an
engine during takeoff) to abort the takeoff in a safe manner, and
consequent reduced controllability of the airplane.

DATES: This AD becomes effective November 30, 2005.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of November 30,
2005.

SUPPLEMENTARY INFORMATION:

Examining the Docket

You may examine the AD docket on the Internet at https://dms.dot.gov
or in person at the Docket Management Facility office between 9 a.m.
and 5 p.m., Monday through Friday, except Federal holidays. The Docket
Management Facility office (telephone (800) 647-5227) is located on the
plaza level of the Nassif Building at the street address stated in the
ADDRESSES section.

Discussion

The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to certain
EMBRAER Model EMB-135BJ, -135ER, -135KE, -135KL, -135LR, -145, -145ER,
-145MR, -145LR, -145XR, -145MP, and -145EP airplanes. That supplemental
NPRM was published in the Federal Register on August 17, 2005 (70 FR
48339). That supplemental NPRM proposed to require modifying the total
air temperature (TAT) sensor heating system. That supplemental NPRM
also allows for replacing the fully automated digital electronic
control (FADEC) unit assemblies with new or modified assemblies as an
additional means of compliance.

New Relevant Service Information

EMBRAER has issued Service Bulletin 145-30-0028, Revision 10, dated
March 22, 2005. Paragraph (f) of the supplemental NPRM refers to
EMBRAER Service Bulletin 145-30-0028, Revision 09, dated March 1, 2004,
as the appropriate source of service information for modifying the TAT
sensor heating system. The applicability statement of the supplemental
NPRM also refers to EMBRAER Service Bulletin 145-30-0028, Revision 09,
as the source in which affected airplanes are identified. Revision 10
of the service bulletin includes minor editorial revisions, but no
substantive changes. Therefore, we have revised the applicability
statement and paragraph (f) of this AD to refer to EMBRAER Service
Bulletin 145-30-0028, Revision 10. We have also revised paragraph (g)
of this AD to give credit for modifications done before the effective
date of this AD in accordance with Revision 09.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.

Support for the Supplemental NPRM

One commenter supports the intent of the supplemental NPRM.

Request To Add Additional Means of Compliance

The airplane manufacturer comments that it has recently approved
FADEC software version 8.0. (Paragraph (h) of the supplemental NPRM
specifies that replacing the existing FADEC assemblies with new or
modified FADEC assemblies that include software version 7.6 is
acceptable for compliance with paragraph (f) of the supplemental NPRM.)
The commenter notes that, because the same features relating to
temperature reading in FADEC software version 7.6 are included in
software version 8.0, FADEC software version 8.0 should also be
referenced as an acceptable means of compliance with the proposed
requirements. The commenter also lists the service bulletins for
installing FADEC software version 8.0.
We agree with the commenter's request. EMBRAER has issued the
service bulletins specified in the table below.

These service bulletins describe procedures for replacing existing
FADEC assemblies with FADEC assemblies that have software version 8.0,
including verifying the part number of the ITT trim plug and replacing
it with an ITT trim plug of another part number if necessary. These
service bulletins also refer to the Rolls-Royce service bulletins
listed in the table above as additional sources of service information
for replacing the FADEC assemblies. The EMBRAER service bulletins
listed in the table also specify that installing the new or modified

[[Page 61731]]

FADEC assemblies that have FADEC software version 8.0 also necessitates
upgrading the engine indication and crew alerting system (EICAS),
central maintenance computer (CMC), and IC-600 configuration modules,
as applicable.
We have revised paragraph (h) and Table 2 of this AD to include
references to these service bulletins and the applicable actions in
them.

Request To Add Reference to Rolls-Royce Service Bulletins

One commenter requests that we revise Table 2 of the supplemental
NPRM to give credit for replacing the FADEC assemblies with new or
modified FADEC assemblies that include software version 7.6 in
accordance with Rolls-Royce Service Bulletin AE3007A-73-067 or AE3007A-
73-069, as applicable. The commenter states that adding these service
bulletins to Table 2 would save it a lot of time that would otherwise
be needed to request an Alternative Method of Compliance (AMOC) and
would save the FAA time that would be needed to address those AMOCs.
We do not agree that any change to this AD is necessary to meet the
intent of the commenter's request. Table 2 of this AD gives credit for
replacing FADEC assemblies with new or modified FADEC assemblies that
include software version 7.6 in accordance with, among other service
bulletins, EMBRAER Service Bulletin 145-73-0022 or 145-73-0024, both
Revision 01, both dated July 15, 2004. We explain in the preamble of
the supplemental NPRM that these EMBRAER Service Bulletins refer to
Rolls-Royce Service Bulletin AE3007A-73-067 and AE3007A-73-069,
respectively, as additional sources of service information for
replacing the FADEC assemblies. We find that doing the actions
specified in Rolls-Royce Service Bulletin AE3007A-73-067 or AE3007A-73-
069 is acceptable for compliance with the corresponding actions
required by paragraph (h) of this AD, provided that all applicable
EICAS, CMC, and IC-600 upgrades; as well as any other applicable
actions associated with upgrading the EICAS, CMC, or IC-600; are also
done, as specified in paragraph 1.C., ``Description--Time for
Accomplishment,'' of EMBRAER Service Bulletin 145-73-0022 or 145-73-
0024, both Revision 01, as required by paragraph (h) of this AD. No
change to the AD is needed in this regard.

Clarification of AMOC Paragraph

We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.

Conclusion

We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

The following table provides the estimated costs for U.S. operators
to comply with this AD.

Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Number of
Average Cost per U.S.-
Action Work hours labor rate Parts airplane registered Fleet cost
per hour airplanes
--------------------------------------------------------------------------------------------------------------------------------------------------------
Modify the TAT sensor heating system........... 8 $65 $443 $963 434 Up to $417,942.
--------------------------------------------------------------------------------------------------------------------------------------------------------

For airplanes modified in accordance with Revisions 04 through 08
of EMBRAER Service Bulletin 145-30-0028, it will take about 1 work hour
per airplane to do the additional modification specified in Part III of
the Accomplishment Instructions of the service bulletin, at an average
labor rate of $65 per work hour. Based on these figures, the estimated
cost of doing this required action is $65 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 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:
(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. See the ADDRESSES
section for a location to examine the regulatory evaluation.
