ERJ-190 Flying Control Rigging Error (UPDATED 25 June 2020 with Final Report)
The Portuguese accident investigation agency, GPIAAF, issued a safety investigation update in on 31 May 2019 on a serious in-flight loss of control event involving Aruba registered Air Astana Embraer ERJ-190 P4-KCJ that occurred on 11 November 2018, immediately after a C2-Check (1C + 2C + 6 year) at the OGMA facility at the Alverca Air Base, in Poartugal. This was a ferry flight back to Kazakhstan with 6 persons on board, not a maintenance check flight.
The aircraft was landed safely but with structural damage sufficient to make this an accident in accordance with ICAO Annex 13. The crew had however encountered considerable difficulty controlling the aircraft, so much so they had debated ditching offshore. However, they regained a degree of control. After two unstabilised approaches, the crew landed runway 19L. The intended runway was 19R, but due to lateral drift they were forced to land on 19L. One passenger fell and suffered a minor injury.
