Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 
STD, -200 LR, and -200 IGW airplanes. This proposed AD was prompted by 
reports of structural cracks in the wing lower skin stringers on both 
half wings. This proposed AD would require repetitive inspections of 
the lower skin stringers on both half wings for cracking or fuel 
leakage, and applicable related investigative and corrective actions, 
as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o 
Civil (ANAC) Brazilian AD, which will be incorporated by reference. The 
FAA is proposing this AD to address the unsafe condition on these 
products.

Discussion

    The ANAC, which is the aviation authority for Brazil, has issued 
Brazilian AD 2019-06-01, effective June 17, 2019 (``Brazilian AD 2019-
06-01'') (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 
IGW, -200 STD, -200 LR, and -200 IGW airplanes. The MCAI states:

    It has been found the occurrence of structural cracks in the 
wing lower skin stringers between ribs 7 and 10 on both half wings. 
The cracks propagation on these wing lower skin stringers may result 
in fuel leakage and reduced wing structural integrity.
    Since this condition may occur in other airplanes of the same 
type and affects flight safety, [related investigative and] a 
corrective action is required. Thus, sufficient reason exists to 
request compliance with this [Brazilian] AD in the indicated time 
limit.

Related IBR Material Under 1 CFR Part 51

    Brazilian AD 2019-06-01 describes procedures for repetitive 
detailed inspections of the lower skin stringers on both half wings for 
cracking or fuel leakage, and applicable related investigative and 
corrective actions. Related investigative actions include a high 
frequency eddy current (HFEC) inspection of any area with crack 
indications to confirm the damage extension. Corrective actions include 
repairs. This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

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 a bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the agency 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in Brazilian AD 2019-06-01 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and the European Aviation 
Safety Agency (EASA) to develop a process to use certain EASA ADs as 
the primary source of information for compliance with requirements for 
corresponding FAA ADs. The FAA has since coordinated with other 
manufacturers and civil aviation authorities (CAAs) to use this 
process. As a result, Brazilian AD 2019-06-01 would be incorporated by 
reference in the FAA final rule. This proposed AD would, therefore, 
require compliance with Brazilian AD 2019-06-01 in its entirety, 
through that incorporation, except for any differences identified as 
exceptions in the regulatory text of this proposed AD. Service 
information specified in Brazilian AD 2019-06-01 that is required for 
compliance with Brazilian AD 2019-06-01 will be available on the 
internet at http://www.regulations.gov by searching for and locating 
Docket No. FAA-2019-0701 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 29 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
12 work-hours x $85 per hour = $1,020........................              $0           $1,020          $29,580
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
               Labor cost                             Parts cost                       Cost per product
----------------------------------------------------------------------------------------------------------------
Up to 898 work-hours x $85 per hour = Up  Negligible........................  Up to $76,330.
 to $76,330.
----------------------------------------------------------------------------------------------------------------

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.
    The FAA is 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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance

[[Page 51471]]

with that order, issuance of ADs is normally a function of the 
Compliance and Airworthiness Division, but during this transition 
period, the Executive Director has delegated the authority to issue ADs 
applicable to transport category airplanes and associated appliances to 
the Director of the System Oversight Division.

Regulatory Findings

    The FAA 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) Will not affect intrastate aviation in Alaska, 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.

List of Subjects in 14 CFR Part 39

accordance with, Brazilian AD 2019-06-01.

(h) Exceptions to Brazilian AD 2019-06-01

    (1) For purposes of determining compliance with the requirements 
of this AD: Where Brazilian AD 2019-06-01 refers to its effective 
date, this AD requires using the effective date of this AD.
    (2) The ``Alternative method of compliance (AMOC)'' section of 
Brazilian AD 2019-06-01 does not apply to this AD.
    (3) Where paragraph (a)(1) of Brazilian AD 2019-06-01 specifies 
an initial inspection time, this AD requires an initial inspection 
at the applicable time specified in paragraph (h)(3)(i) or (ii) of 
this AD, whichever occurs later.
    (i) Before the accumulation of 17,000 total flight cycles or 
27,000 total flight hours, whichever occurs first.
    (ii) Within 680 flight cycles or 900 flight hours after the 
effective date of this AD, whichever occurs first.
    (4) Where paragraph (a)(1)(ii) of Brazilian AD 2019-06-01 
specifies to do a special detailed inspection (SDI) in case of any 
``signal'' of cracks, this AD requires doing an SDI before further 
flight after the detection of any ``sign'' of structural cracks in 
the inspected area.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information
