Détails:
The crew of the Airbus A319 took off from Hamburg Fuhlsbüttel, Germany, at 07:26 hours local time for flight AF2511 to Paris-CDG, France. The pilot-in-command was the Pilot Flying (PF).
At 08:09 the crew began the descent from FL380 and prepared for an ILS approach for runway 27R in daytime instrument conditions
At 08:40, at a distance of approximately 14 NM from threshold of runway 27R, the aircraft was established on the glide slope. During the approach the flight encountered turbulent winds, causing the aircraft toll with an amplitude reaching 5° to the left and 4° to the right. The attitude oscillates changed between approximately 0.5° and 2.5° nose-up.
At 3,500 feet the Pilot Flying disengaged the autothrottle and autopilot and continued the approach manually. The controller cleared the flight to land and reported a wind 220° at 25 kt with gusts to 38 kt. The aircraft remained on the localizer while the roll oscillating between 6° left and 6.5° right. The attitude of the aircraft varied between 1° nose down and 6,5° nose-up. The aircraft oscillated with a maximum deviation of about 80 ft below and about 110 ft above the glideslope. The angle of drift of the aircraft varied between 10° and 15° with the nose of the aircraft to the left of the axis of the localizer.
At 08:44 the crew deployed the undercarriage. Passing 1000 ft radio altitude the aircraft was stabilized. Subsequently the indicated airspeed fluctuated and remained higher than the Vapp target speed.
As the aircraft descended through 200 feet, the approach became unstabilized. The captain noticed three red and one white PAPI light, indicating he was slightly below the glide slope. The left wing dropped.
At 08:46 the aircraft began to flare at a height of 15 feet above the runway and a speed of 155 kts (Vapp target = 138 kts).
The aircraft then touched down with the main landing gear hitting the runway with a vertical load factor of 2.66 g. The longitudinal attitude is + 3.5 ° with a 2.5° roll to the right and a descent rate of about -800 ft/min.

Probable Cause:

Causes
L’atterrissage dur résulte d’une vitesse verticale excessive lors du toucher des roues en raison:
- d’ordres à piquer proches du toucher (25 et 20 ft radio-sonde) ;
- d’un arrondi débuté tardivement à une hauteur radio-sonde d’environ 15 ft ;
- d’une vitesse indiquée excessive (Vapp + 17 kt lors du toucher) et donc d’un fort taux de descente.
La charge de travail élevée du PF induite par le pilotage manuel dans des conditions de forts vents turbulents et l’absence d’annonce d’interruption de l’approche du PM malgré l’existence de critères objectifs de déstabilisation après le passage des 200 ft n’ont pas permis à l’équipage de prendre la décision d’interrompre l’approche.
