In March 2019, Part 121 air carriers were required to begin offering upset prevention and recovery training (UPRT) to pilots who train under an advanced qualifications program (AQP) outlined in Public Law 111-216 section 208. That law was created in part, following the 2009 loss of control crash of a Colgan Airlines Dash 8 Q400 near Buffalo, New York. That requirement eventually translated into FAR 121.423.
