Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model ERJ 170 Airplanes and Model ERJ 190 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to all EMBRAER Model ERJ 170-100 LR, -100 STD, -100 
SE, and -100 SU airplanes. That AD currently requires repetitively 
replacing the low-stage check valve and associated seals of the right-
hand engine bleed system. This new AD adds new airplanes to that 
existing requirement. For all airplanes, this AD also requires 
repetitively replacing the low-stage check valve and associated seals 
of the left-hand engine bleed system with a new check valve and new 
seals. This AD results from a report that an engine shut down during 
flight due to the failure of the low-stage check valve to close. We are 
issuing this AD to prevent failure of the low-stage check valve, which 
could result in an engine shutting down during flight.

DATES: This AD becomes effective September 13, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of September 13, 
2007.
    On November 29, 2005 (70 FR 69075, November 14, 2005), the Director 
of the Federal Register approved the incorporation by reference of a 
certain service bulletin.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the AD docket on the Internet at http://dms.dot.gov 
or in person at the Docket Operations office between 9 a.m. and 5 p.m., 
Monday through Friday, except Federal holidays. The Docket Operations 
office (telephone (800) 647-5527) is located on the ground floor of the 
West Building at the DOT 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 supersedes AD 2005-23-14, amendment 
39-14372 (70 FR 69075, November 14, 2005). The existing AD applies to 
all EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU 
airplanes. That NPRM was published in the Federal Register on May 8, 
2007 (72 FR 26008). That NPRM proposed to continue to require 
repetitively replacing the low-stage check valve and associated seals 
of the right-hand (RH) engine bleed system. That NPRM also proposed to 
add new airplanes to that existing requirement. For all airplanes, that 
NPRM also proposed to require repetitively replacing the low-stage 
check valve and associated seals of the left-hand (LH) engine bleed 
system with a new check valve and new seals.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

Changes to This AD

    We have reviewed Revision 01 of EMBRAER Service Bulletin 190-36-
0004, dated November 14, 2006, and have determined that the 
accomplishment instructions of Revision 01 are the same as those in the 
original issue of the service bulletin. In the NPRM, we referred to the 
original issue of EMBRAER Service Bulletin 190-36-0004, dated October 
18, 2006, as the appropriate source of service information for 
replacing the low-stage check valves and associated seals of the RH and 
LH engine bleed system, on Model ERJ 190-100 STD, -100 LR, and -100 IGW 
airplanes. Therefore, we have revised paragraphs (j) and (k) of this AD 
to also refer to Revision 01 of EMBRAER Service Bulletin 190-36-0004, 
dated November 14, 2006, as an appropriate source of service 
information. We have

[[Page 44735]]

also revised paragraph (n) of this AD to specify that this AD does not 
require sending to the manufacturer any check valve removed in 
accordance with Revision 01 of EMBRAER Service Bulletin 190-36-0004.

Conclusion

    We have carefully reviewed the available data 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.

Interim Action

    This AD is considered to be interim action. The manufacturer has 
advised that it currently is developing a modification that will 
address the unsafe condition addressed by this AD. Once this 
modification is approved we might consider additional rulemaking.

Costs of Compliance

    The following table provides the estimated costs, at an average 
labor rate of $80 per work hour, for U.S. operators to comply with this 
AD. The parts manufacturer states that it will supply required parts to 
operators at no cost.

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

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.
