CHI96LA070

the pilot's failure to maintain adequate airspeed during the landing. The weather and ice accumulation on the airplane were factors.

The pilot reported that while descending and being vectored on the localizer approach, the airplane accumulated mixed but mostly clear ice. He executed a missed approach, subjecting the airplane to 'extended exposure to ice conditions.' on his next approach, the pilot stated that he experienced 'deterioration of performance resulting in a near ground stall and hard landing.'

On December 29, 1995, at 1731 central standard time (cst), a Cessna 310R, N68300, operated by a private pilot, sustained substantial damage during a hard landing. Instrument meteorological conditions prevailed at the time of the accident. The flight was being conducted under 14 CFR Part 91. An instrument flight plan was on file. The pilot reported no injuries to himself or the three passengers on board. The flight originated at Madison, Wisconsin, at 1600 cst. In his written statement, the pilot reported that "while descending, being vectored and on the localizer approach for runway 36" at Noble Lee/Lakeland Airport, Minocqua, Wisconsin, "mixed, but mostly clear ice accumulated on the airplane." The pilot executed a missed approach which subjected the airplane to "extended exposure to ice conditions." On his next approach, the pilot stated that he experienced "deterioration of performance resulting in a near ground stall and hard landing." The pilot received a weather briefing from the Flight Service Station at Green Bay, Wisconsin, at 1530 cst. No reports of icing or forecast icing conditions for his route of flight were contained in that briefing. A Federal Aviation Administration inspector examined the airplane at Noble Lee/Lakeland Airport on January 2, 1996. He found the front carry-through spar on the right wing bent slightly rearward. There was damage to the right propeller and skin wrinkles to the right side of the fuselage just aft of the passenger window, and to the underside of the right wing from the wing root to the right engine locker. Examination of the engines, engine controls, flight controls and other airplane systems showed no anomalies. -
