AD 2021-18-03 Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
Models named: ERJ 190-400. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Yaborã Indústria Aeronáutica S.A. (type certificate previously held by Embraer S.A.) Model ERJ 190-400 airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2020-07-01R01, effective March 26, 2021 (ANAC AD 2020-07-01R01).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2020-07-01R01.
Unsafe condition
This AD was prompted by a report of an in-flight shutdown (IFSD) due in part to failure in the low-pressure compressor (LPC) rotor 1 during operation in high altitude at high thrust settings, and by the development of updated electronic engine control (EEC) software that will prevent the unsafe condition. The FAA is issuing this AD to address uncontained release of the LPC rotor 1 and damage to the engine and airplane structure, which could result in loss of control of the airplane.
Affected ADs
This AD replaces AD 2020-26-02, Amendment 39-21357 (85 FR 81790, December 17, 2020) (AD 2020-26-02).
