"Aircraft Damage: Substantial"
"The aircraft is currently unserviceable"
"The First Officer (FO) was the Pilot-Flying from the Top of Descent"
*****
And similar to what I wrote in posts about my experience at landing.
QUOTE:
"At approximately 200 feet above the runway while continuing to descend to the touch down point the aircraft entered into series of minor lateral roll deviations followed by a pronounced roll first to the left and then to the right, the Pilot-Flying introduced large control inputs into the aircraft to control the sudden and unanticipated roll behaviour.
The aircraft was not wings level at the touchdown point as it was rolling to the right. On touchdown the right-hand main gear contacted the runway first.
With a high rate of descent in conjunction with a nose high pitch attitude, the underside of the rear fuselage contacted the runway surface during the hard landing, the aircraft then bounced before returning to the runway centreline. "
