Probable cause

The pilot's failure to maintain adequate airspeed during the landing which resulted in an inadequate flare. Contributingto the accident were the icing conditions and ice accumulation of the wings of the airplane.

Analysis

During an ILS localizer approach, the acft landed hard causing substantial damage to the wing spar. The plt said he had accumulated substantial ice on the acft and utilized the deicing equipment shortly before ldg. He said he crossed the runway threshold at 100 knots and reduced power. The acft pitched down suddenly, then power and back pressure were applied to cushion the ldg. The acft hit hard, bounced, then settled on the runway. It was then taxied back to the ramp.
