My understanding is that the fuselage/engine damage was caused by hitting the approach lights while making an early touch-down before the threshold. It is not confirmd whether this happened duing the prior touch-and-go
pr the final landing, but the cloud of snow on touchdown in the video suggests the latter. Not hard to envision with the adrenaline still running after the bounce, likely made worse by all the bells, whistles and xmas tree lights and not knowing the extent of structural damage.
