Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
Superseded. A later AD replaced this one: AD 2021-18-03. Comply with the one in force.
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 2020-07-01, effective July 15, 2020 (ANAC AD 2020-07-01).
The FAA is adopting a new airworthiness directive (AD) for certain Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. (type certificate previously held by Embraer S.A.) Model ERJ 190-400 airplanes. 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. This AD requires amending the airplane flight manual (AFM) to incorporate a new limitation and revise certain normal procedures, 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.
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 2020-07-01.
(1) Where ANAC AD 2020-07-01 refers to its effective date, this AD requires using after the effective date of this AD.
(2) The “Alternative method of compliance (AMOCs)” section of ANAC AD 2020-07-01 does not apply to this AD.
