E75S, vicinity Atlanta GA USA, 2016

Summary

On 6 November 2019, the crew of an Embraer E175LR which had just taken off from Atlanta experienced difficulty in maintaining pitch control after an apparent pitch trim runaway and an emergency was declared. Control was subsequently regained and a return to land was made without further problems. The Investigation is continuing but has identified the root cause as wiring damage arising from incorrect installation, noted that potentially related corrective action was not mandated and determined that the operator’s QRH drill for the situation encountered had significantly contained only one memory action rather the two in the aircraft manufacturer’s version.
