[Docket No. FAA-2019-0975; Product Identifier 2019-NM-176-AD]
RIN 2120-AA64


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 170 airplanes. This proposed AD was 
prompted by a report of erroneous indications of certain engine 
parameters and reports of ``pitch up'' and ``pitch down'' uncommanded 
attitudes with autopilot engaged in cruise flight. This proposed AD 
would require installing updated PRIMUS EPIC LOAD software, 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.

DATES: The FAA must receive comments on this proposed AD by January 31, 
2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The ANAC, which is the aviation authority for Brazil, has issued 
Brazilian AD 2019-10-02, effective October 21, 2019 (``Brazilian AD 
2019-10-02'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 
SE, and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, -200 STD, 
and -200 LL airplanes.
    This AD was prompted by a report of erroneous indications of the 
engine parameters N1, N2, and ITT from both engines due to the design 
of data communication of the full authority digital engine control 
(FADEC) 1 and 2 with the engine indicating and crew alerting system 
(EICAS) display, which could result in interference with decisions that 
must be taken by the flight crew during takeoff. This AD was also 
prompted by reports of ``pitch up'' and ``pitch down'' uncommanded 
attitudes with autopilot engaged in cruise flight, which could occur in 
``Autoland'' mode during landing. The FAA is proposing this AD to 
address these conditions, which could interfere with the decisions 
taken by the flight crew during takeoff and landing and possibly result 
in reduced controllability of the airplane. See the MCAI for additional 
background information.

Related IBR Material Under 1 CFR Part 51

    Brazilian AD 2019-10-02 describes procedures for installing updated 
PRIMUS EPIC LOAD software. 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 2019-10-02 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 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-
10-02 will be incorporated by reference in the FAA final rule. This 
proposed AD would, therefore, require compliance with Brazilian AD 
2019-10-02 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 2019-10-02 
that is required for compliance with Brazilian AD 2019-10-02 will be 
available on the internet at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2019-0975 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 540 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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 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.

design of data communication of the full authority digital engine 
control (FADEC) 1 and 2 with the engine indicating and crew alerting 
system (EICAS) display, which could result in interference with 
decisions that must be taken by the flight crew during takeoff. This 
AD was also prompted by reports of ``pitch up'' and ``pitch down'' 
uncommanded attitudes with autopilot engaged in cruise flight, which 
could occur in ``Autoland'' mode during landing. The FAA is 
proposing this AD to address these conditions, which could interfere 
with the decisions taken by the flight crew during takeoff and 
landing and possibly result in reduced controllability of the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all
