Was this required? This was an unstabilized approach. A GA would have prevented the nightmare. From the latest safety first.

​​​​​​CASE STUDY 1: BOUNCED LANDING, NOSE LANDING GEAR IMPACT, AND A TAIL STRIKE ON GO-AROUNDEvent Description

An A320 was on the final approach segment of its ILS approach, configured for landing (CONF FULL).

The Pilot Flying (PF) disconnected the autopilot at 370 ft Radio Altitude (RA) and kept autothrust ON. At 200 ft, tailwind variations caused the airspeed to drop below approach speed (Vapp).

From 100 ft RA and below, high tailwind gradients maintained the airspeed below Vapp -5 kt despite autothrust increase and reached a minimum of 119 kt (Vapp -20 kt) at 5 ft RA.

The PF performed the flare at 14 ft and at the same time started to slowly push the thrust levers above CLB detent.

The aircraft touched down on its main landing gear and bounced. During the bounce, a PITCH PITCH auto callout triggered.

The PF applied full nose down order and retarded the thrust levers to IDLE. This triggered an extension of ground spoilers leading the aircraft to heavily impact the runway , first with its nose landing gear and then its main landing gear.

The impact of the nose gear resulted in another sudden increase of the aircraft’s pitch and the PITCH PITCH auto callout triggered for a second time. The PF initiated a go-around by setting TOGA thrust and applying a full nose up command. There was a tail strike as the aircraft lifted off from the runway at 133 kt.

The NLG wheels separated due to the impact of the NLG on the runway and one wheel was sucked into Engine 1, causing this engine to stall. Other system failures occurred due to the impact on the NLG and these caused the aircraft to revert to alternate law. The flight crew diverted to a different airport and eventually landed the aircraft.
