Aeroflot Sukhoi Superjet crash 2019, that killed 41 occupants

Russian investigators have released the final report of their inestigation into the crash of an Aeroflot Sukhoi Superjet in May 2019, that killed 41 occupants.
"The cause of the aviation accident involving the RRJ-95B aircraft (registration RA-89098) was the uncoordinated control inputs by the captain during the flare phase of landing and during the repeated bounces of the aircraft off the runway (“porpoising”), which were characterized by multiple, disproportionate, alternating movements of the control stick, with it being held at extreme positions. These control actions led to three hard landings, and during the second and third landings, the absorbed energy levels significantly exceeded the maximum values considered during the aircraft type certification strength assessment. This resulted in the destruction of structural load-bearing elements of the airframe, rupture of fuel tanks with fuel spillage, and the outbreak of a fire.
