Analysis

The acft picked up moderate to severe icing which the pilot thought he had shaken off as he cycled the deice boots. He saw the ice come off of the wings but could not see the horizontal stabilizer. On short final at 100 KTS the control yoke began vibrating. He increased airspeed & lowered the nose but was unable to flare resulting in a hard landing. Clear ice chunks were found on the runway which apparently broke off on landing. An operational check of the deice bootsperformed at a later date was satisfactory on both the wing & horizontal stabilizer surfaces.
