The ATP landed in a strong cross-wind (200deg at a mean speed of 30 knots with gusts to 45 knots and occasionally 50 knots) which was close to the maximum demonstrated for that type. The aircraft touched down firmly on runway 27 in a flat attitude and bounced into the air. During the attempt to complete the landing, a pitch oscillation rapidly developed which resulted in two more bounces, each ending with a nose-first touch-down. On the fourth touch-down, which again was nose-first, the nose landing gear collapsed and the aircraft slid along the runway with the nose landing gear folded aft under the fuselage and debris punctured the fuselage pressure hull. The propeller tips disintegrated on contact with the runway. The aircraft came to rest on grass adjacent to the runway and no one was injured. CAUSAL FACTORS: (i) The adverse weather conditions which existed at the time of the landing. (ii) The commander’s decision to fly the approach at an airspeed which exceeded that recommended in the Operations Manual. (iii) The commander’s misjudgement of the landing flare and the recovery from the subsequent bounce. A contributory factor may have been the distraction of a caution warning which occurred immediately before touch-down.
