Airworthiness Directive 2020-05708
one-timeAirworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
What this AD requires
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.
Which aircraft AD 2020-05708 applies to
Applicability set by Brazilian ANAC AD 2019-10-02, effective October 21, 2019. Type certificate previously held by Embraer S.A.
Whether AD 2020-05708 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
