The final approach was considered stabilized. At about 40 feet above ground level, a significant tailwind gust of about 25 knots was experienced, creating a loss of airspeed. The loss of airspeed resulted in a loss of lift at a low height and led to a hard touchdown. At about 10 feet above the runway (and before the hard touchdown) the flight crew set “TOGA” thrust for go-around and applied full back stick pressure resulting in a pitch increase to +9.2 degrees. The engines required time to spool up and the airplane lost altitude before it started to climb. The increase in pitch and delay in thrust caused the tailstrike, resulting in substantial damage to the airplane. The airplane was fitted with a tailstrike prevention option which appears on the primary flight director (PFD) when below 400 feet but deactivates when thrust levers are pushed to “TOGA”. Standard operating procedures for go-arounds near the ground inform flight crews to avoid an excessive rotation rate to prevent tailstrikes.
