Airworthiness Directives; Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes

Publication summary

The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by a report of uncommanded setting of the barometric reference in both primary flight displays (PFDs) due to the architecture of data communication of the Control I/O modules, which interconnect the display controllers to the air data system. This AD requires installing updated Primus EPIC software, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Unsafe Condition
(e) Unsafe Condition

    This AD was prompted by a report of uncommanded setting of the 
barometric reference in both primary flight displays due to the 
architecture of data communication of the Control I/O modules, which 
interconnect the display controllers to the air data system. The FAA 
is issuing this AD to address this condition, which could interfere 
with the decisions taken by the flightcrew during critical phases of 
flight, and possibly result in reduced controllability of the 
airplane.

SUPPLEMENTARY INFORMATION: 

Background

    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 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, 
and -200 IGW airplanes. The NPRM published in the Federal Register on 
October 20, 2022 (87 FR 63704). The NPRM was prompted by AD 2022-05-04, 
effective May 25, 2022, issued by ANAC, which is the aviation authority 
for Brazil (ANAC AD 2022-05-04) (referred to after this as the MCAI). 
The MCAI states that there was a report of uncommanded setting of the 
barometric reference in both PFDs due to the architecture of data 
communication of the Control I/O modules, which interconnect the 
display controllers to the air data system. The possibility of 
erroneous indications for both pilots, combined with possible adverse 
meteorological conditions could result in an increase of flightcrew 
workload. This condition, if not addressed, could interfere with the 
decisions taken by the flightcrew during critical phases of flight.
    In the NPRM, the FAA proposed to require installing updated Primus 
EPIC software, as specified in ANAC AD 2022-05-04. The FAA is issuing 
this AD to address uncommanded setting of the barometric reference in 
both primary flight displays, which could interfere with the decisions 
taken by the flightcrew during critical phases of flight, and possibly 
result in reduced controllability of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1246.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from the Air Line Pilots Association, 
International (ALPA) who supported the NPRM without change.

Conclusion

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA reviewed the relevant data, considered the 
comment received, and determined that air safety requires adopting this 
AD as proposed. Accordingly, the FAA is issuing this AD to address the 
unsafe condition on this product. This AD is adopted as proposed in the 
NPRM.

Related Service Information Under 1 CFR Part 51

    This AD requires ANAC AD 2022-05-04, which specifies procedures for 
installing updated Primus EPIC 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 
ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 121 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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.

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.
