Airworthiness Directives; Embraer S.A. Airplanes

FAA / Federal Register · 2019-27062

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This proposed 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 proposed AD would require installing updated PRIMUS EPIC LOAD software, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) Brazilian AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
