This AD applies to Yaborã Indústria Aeronáutica S.A. (Type certificate previously held by 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; certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) Brazilian AD 2019-10-02, effective October 21, 2019 (“Brazilian AD 2019-10-02”).
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 170 airplanes. This 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 AD requires installing updated PRIMUS EPIC LOAD software, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) Brazilian 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, Brazilian AD 2019-10-02.
(1) Where Brazilian AD 2019-10-02 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Alternative method of compliance (AMOC)” section of Brazilian AD 2019-10-02 does not apply to this AD.
(3) Where paragraph (d) of Brazilian AD 2019-10-02 specifies you must use certain service information for software installation, this AD specifies to use that service information as applicable, except as provided in paragraphs (a)(1) through (3) of Brazilian AD 2019-10-02.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
