SUPPLEMENTARY INFORMATION: 

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian AD 
2019-02-02, dated February 28, 2019 (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; Model ERJ 190-100 STD, -100 LR, -100 ECJ, and -100 IGW 
airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. 
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-2019-
0325.
    The FAA 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; Model ERJ 190-100 STD, -100 LR, -100 ECJ, and 
-100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW 
airplanes. The NPRM published in the Federal Register on May 29, 2019 
(84 FR 24730). The NPRM was prompted by reports of the RAT compartment 
door seal peeling off and tangling up on the RAT rotor during flight 
test. The NPRM proposed to require a general visual inspection for 
peeling-off of the RAT compartment door seal, bonding if necessary, and 
the rework of the RAT compartment door seal attachment.
    The FAA is issuing this AD to address the possible loss of the RAT 
function, which, when associated with an emergency electrical event, 
can result in the loss of airplane controllability. See the MCAI for 
additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment. The Air 
Line Pilots Association, International (ALPA) expressed support for the 
NPRM.

Request To Extend Compliance Time

    JetBlue Airways and SkyWest Airlines Inc. requested an extension of 
the compliance time in paragraph (g)(1) of the proposed AD from 750 
flight hours to 2,500 flight hours or 12 months. The commenters 
asserted that the new interval would align with the scheduled 
Maintenance Review Board tasks on the RAT, and that performing the AD 
at the same time as scheduled tasks would decrease the logistical 
burden of compliance.
    The FAA disagrees with the commenters' request because the proposal 
contains no justification to show that an acceptable level of safety 
would be maintained. The FAA may, however, consider approving a longer 
compliance time as an alternative method of compliance (AMOC) with 
paragraph (g)(1) of this AD if sufficient substantiation is provided to 
show an acceptable level of safety. This AD has not been changed in 
this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     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.
    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 AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. 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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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) 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.
