(EMBRAER) Model ERJ 170 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model ERJ 170 airplanes. This AD requires revising the Airworthiness Limitations section (ALS) of the airplane maintenance manual (AMM) to include new, specific maintenance tasks related to the incorporation of a new horizontal stabilizer actuator. This AD also requires revising the ALS of the AMM to include revised repetitive inspection intervals for certain tasks in the maintenance plan related to the aileron and flap/slat flight controls system. This AD results from safety assessments of the aileron and flap/slat flight controls system, conducted after the type certification of the airplane, which showed that some dormant faults did not comply with the safety assessment criteria. We are issuing this AD to prevent failure of the aileron and flap/ slat controls system, which could result in reduced controllability of the airplane. DATES: This AD becomes effective April 26, 2006. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of April 26, 2006.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the airworthiness directive (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 notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all EMBRAER Model ERJ 170 airplanes. That NPRM was published in the Federal Register on January 4, 2006 (71 FR 290). That NPRM proposed to require revising the Airworthiness Limitations section (ALS) of the airplane maintenance manual (AMM) to include new, specific maintenance tasks related to the incorporation of a new horizontal stabilizer actuator. That NPRM also proposed to require revising the ALS of the AMM to include revised repetitive inspection intervals for certain tasks in the maintenance plan related to the aileron and flap/slat flight controls system. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the single comment received. The commenter, the Airline Pilots Association, International, supports the NPRM. Conclusion We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed. cprice-sewell on PROD1PC70 with RULES Costs of Compliance This AD will affect about 42 airplanes of U.S. registry. The required actions will take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $2,730, or $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, VerDate Aug<31>2005 15:10 Mar 21, 2006 Jkt 208001 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.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
EMBRAER Model ERJ 170 airplanes. This AD requires revising the
Airworthiness Limitations section (ALS) of the airplane maintenance
manual (AMM) to include new, specific maintenance tasks related to the

requires revising the ALS of the AMM to include revised repetitive
inspection intervals for certain tasks in the maintenance plan related
to the aileron and flap/slat flight controls system. This AD results
from safety assessments of the aileron and flap/slat flight controls
system, conducted after the type certification of the airplane, which
showed that some dormant faults did not comply with the safety
assessment criteria. We are issuing this AD to prevent failure of the
aileron and flap/slat controls system, which could result in reduced
controllability of the airplane.

SUPPLEMENTARY INFORMATION:

Examining the Docket

You may examine the airworthiness directive (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

Building at the street address stated in the ADDRESSES section.

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to all EMBRAER Model ERJ
170 airplanes. That NPRM was published in the Federal Register on
January 4, 2006 (71 FR 290). That NPRM proposed to require revising the
Airworthiness Limitations section (ALS) of the airplane maintenance
manual (AMM) to include new, specific maintenance tasks related to the
incorporation of a new horizontal stabilizer actuator. That NPRM also
proposed to require revising the ALS of the AMM to include revised
repetitive inspection intervals for certain tasks in the maintenance
plan related to the aileron and flap/slat flight controls system.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the single comment received.
The commenter, the Airline Pilots Association, International, supports
the NPRM.

Conclusion

We have carefully reviewed the available data, including the
comment received, and determined that air safety and the public
interest require adopting the AD as proposed.

Costs of Compliance

This AD will affect about 42 airplanes of U.S. registry. The
required actions will take about 1 work hour per airplane, at an
average labor rate of $65 per work hour. Based on these figures, the
estimated cost of the AD for U.S. operators is $2,730, or $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.
