AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed 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: During ERJ 170 airplane full scale fatigue test, cracks
were found in some structural components of the airplane. Analysis of
these cracks resulted in modifications on the airplane Airworthiness
Limitation Items (ALI), to include new inspections tasks or
modification of existing ones and its respective thresholds and
intervals. Failure to inspect these components according to the new
tasks, thresholds and intervals could prevent a timely detection of
fatigue cracks. Undetected fatigue cracks in these areas could
adversely affect the structural integrity of these airplanes.
The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by April 19, 2010.

Discussion
The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC),
which is the aviation authority for Brazil, has issued Brazilian
Airworthiness Directive 2009-04-01, effective April 29, 2009 (referred
to after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
During ERJ 170 airplane full scale fatigue test, cracks were
found in some structural components of the airplane. Analysis of
these cracks resulted in modifications on the airplane Airworthiness
Limitation Items (ALI), to include new inspections tasks or
modification of existing ones and its respective thresholds and
intervals.
Failure to inspect these components according to the new tasks,
thresholds and intervals could prevent a timely detection of fatigue
cracks. Undetected fatigue cracks in these areas could adversely
affect the structural integrity of these airplanes.
* * * * *
The corrective action is revising the Airworthiness Limitations Section
of the Instructions for Continued Airworthiness to incorporate new
structural inspection requirements. You may obtain further information
by examining the MCAI in the AD docket.
Relevant Service Information
Embraer has issued temporary revisions to Appendix A--Part 2 of the
Embraer 170 Maintenance Review Board Report MRB-1621, as identified in
the following table.
Embraer 170 Temporary Revisions
------------------------------------------------------------------------
Temporary revision Date
------------------------------------------------------------------------
TR 4-1.................................... October 15, 2007.
TR 4-3.................................... December 6, 2007.
TR 4-4.................................... January 18, 2008.
------------------------------------------------------------------------
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
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 proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 166 products of U.S. registry. We also estimate that
it would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $14,110, or $85 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 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 this proposed
regulation:
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 proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
[[Page 9813]]
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Empresa Brasileira De Aeronautica S.A. (EMBRAER): Docket No. FAA-
2010-0176; Directorate Identifier 2009-NM-201-AD.
Comments Due Date
(a) We must receive comments by April 19, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Empresa Brasileira de Aeronautica
S.A. (EMBRAER) Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -
200 LR, -200 STD, and -200 SU airplanes; certificated in any
category.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (h) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued operational safety of the airplane. The FAA has
provided guidance for this determination in Advisory Circular (AC)
25-1529-1A.
Subject
(d) Air Transport Association (ATA) of America Code 53:
Fuselage; 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During ERJ 170 airplane full scale fatigue test, cracks were
found in some structural components of the airplane. Analysis of
these cracks resulted in modifications on the airplane Airworthiness
Limitation Items (ALI), to include new inspections tasks or
modification of existing ones and its respective thresholds and
intervals.
Failure to inspect these components according to the new tasks,
thresholds and intervals, could prevent a timely detection of
fatigue cracks. Undetected fatigue cracks in these areas could
adversely affect the structural integrity of these airplanes.
* * * * *
The corrective action is revising the Airworthiness Limitations
Section (ALS) of the Instructions for Continued Airworthiness to
incorporate new structural inspection requirements.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Unless already done, do the following actions.
(1) Within 90 days after the effective date of this AD revise
the ALS of the Instructions for Continued Airworthiness (ICA) to
incorporate the inspection tasks identified in the Embraer temporary
revisions (TRs) to Appendix A--Part 2 of the Embraer 170 Maintenance
Review Board Report MRB-1621, listed in Table 1 of this AD. The
initial compliance times for the tasks start from the applicable
threshold times specified in the TRs for the corresponding tasks of
the maintenance review board report or within 500 flight cycles
after the effective date of this AD, whichever occurs later. For
certain tasks, the compliance times depend on the pre-modification
and post-modification status of the actions specified in the
associated service bulletin, as specified in the ``Applicability''
column of the applicable TRs identified in Table 1 of this AD. The
threshold values stated in the TRs referenced in Table 1 of this AD
are total flight cycles on the airplane since the date of issuance
of the original Brazilian airworthiness certificate or the date of
issuance of the original Brazilian export certificate of
airworthiness.

(2) After accomplishing the actions specified in paragraph
(g)(1) of this AD, no alternative inspections or inspection
intervals may be used unless the inspection or inspection interval
is approved by the Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA, or the Ag[ecirc]ncia Nacional de
Avia[ccedil][atilde]o Civil (ANAC) (or its delegated agent); or
unless the inspection or interval is approved as an alternative
method of compliance (AMOC) in accordance with the procedures
specified in paragraph (h)(1) of this AD.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service
information as follows: No differences.
Other FAA AD Provisions
(h) 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
