Airworthiness Directives; Embraer S.A. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Embraer S.A. Model ERJ 170 airplanes and Model ERJ 190-100 STD, -100 
LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was 
prompted by an evaluation by the design approval holder indicating that 
the forward pressure bulkhead is subject to widespread fatigue damage. 
This AD requires repetitive detailed inspections of the web aft face of 
the forward pressure bulkhead for any cracking and discrepancy, and 
repair if necessary. This AD also requires modification of the forward 
pressure bulkhead, which would terminate the inspections. We are 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective November 27, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 27, 
2017.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Embraer S.A. Model 
ERJ 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 
STD, -200 LR, and -200 IGW airplanes. The NPRM published in the Federal 
Register on July 17, 2017 (82 FR 32658) (``the NPRM'').
    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directive 2017-03-01, effective March 24, 2017 (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 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 IGW, -
200 STD, -200 LR, and -200 IGW airplanes. The MCAI states:

    This [Brazilian] AD was prompted by an evaluation by the design 
approval holder indicating that the forward pressure bulkhead is 
subject to widespread fatigue damage. The modification required by 
this [Brazilian] AD is intended to support the airplane reaching its 
limit of validity (LOV) of the engineering data that support the 
established structural maintenance program. We are issuing this 
[Brazilian] AD to prevent fatigue cracking of the forward pressure 
bulkhead, which could result in reduced structural integrity of the 
airplane.

    Required actions include repetitive detailed inspections of the web 
aft face of the forward pressure bulkhead for any cracking and 
discrepancy (i.e., corrosion, dents, gauge marks, fastener anomalies); 
repair if necessary; and modification of the forward pressure bulkhead, 
which would terminate the repetitive inspections. You may examine the 
MCAI in the AD docket on the Internet at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2017-0697.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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

[[Page 48923]]

In accordance 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 to the Director 
of the System Oversight Division.

Regulatory Findings

    We 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 the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
