Airworthiness Directives; Yabora Industria Aeronautica S.A. Type Certificate Previously Held by Embraer S.A. Airplanes Federal Aviation Administration FAA, Department of Transportation DOT.
ACTION: Final rule.
AGENCY:

The FAA is superseding Airworthiness Directive AD 201416
16, which applied to all Embraer S.A.
Model ERJ 190100 STD, 100 LR, 100
ECJ, 100 IGW, 200 STD, 200 LR, and 200 IGW airplanes; and AD 201819
28, which applied to certain Embraer S.A. Model ERJ 190100 STD, 100 LR, 100 ECJ, 100 IGW, 200 STD, 200
LR, and 200 IGW airplanes. AD 2014
1616 required, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitive retorquing of those fittings.
AD 20181928 required modification of the attaching parts of the pylon lower link fittings. This AD continues to require those actions, and also requires application of a lower torque value, inspection of certain shear pins and replacement if necessary, and revised compliance times for the modification;
as specified in an Agencia Nacional de Aviacao Civil ANAC AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

SUMMARY:

This AD is effective January 20, 2022.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of January 20, 2022.
The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of September 2, 2014 79 FR

SUPPLEMENTARY INFORMATION:
Background ANAC, which is the aviation authority for Brazil, has issued ANAC
AD 20200602R02, effective November 30, 2020 ANAC AD 20200602R02
also referred to as the MCAI, to correct an unsafe condition for certain Yabora Industria Aeronautica S.A. Model ERJ
190100 STD, 100 LR, 100 ECJ, 100
IGW, 200 STD, 200 LR, and 200 IGW
airplanes. Model 190100 SR airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20141616, Amendment 3917940 79 FR 48018, August 15, 2014 AD 20141616; and AD 20181928, Amendment 3919429
83 FR 48935, September 28, 2018 AD
20181928. AD 20141616 applied to all Embraer S.A. Model ERJ 190100
STD, 100 LR, 100 ECJ, 100 IGW, 200 STD, 200 LR, and 200 IGW
airplanes. AD 20181928 applied 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 August 24, 2021 86
FR 47252. The NPRM was prompted by reports of bushing migration, loss of nut torque on the engine pylon lower inboard and outboard link fittings, a loose lower link assembly, and damaged nuts. The existing torque values could cause damage to the nuts, which could lead to loss of the shear pins of the pylon outboard and inboard lower link fittings. In addition, the existing compliance time for the modification of the pylon lower link fitting attaching parts has been found to be inadequate to address the unsafe condition. The NPRM proposed to continue to require the requirements of ADs 20141616
and 20181928, as specified in ANAC
AD 20200602R02. The NPRM also proposed to require application of a lower torque value, inspection of certain shear pins and replacement if necessary, and revised compliance times for the modification, as specified in ANAC AD
20200602R02. The NPRM also proposed to prohibit the installation of affected parts.
The FAA is issuing this AD to address loss of integrity of the engine pylon lower link fittings, which could lead to separation of the engine from the wing.
