Analysis

The plt had recently purchased the acft. While on a x-country trip, he landed at an arpt with an elevation of 4363 ft & refueled. When he was taking off, the density alt was aprx 7089 ft & the acft was near its max gross wt limit. Shortly after lift-off, the plt radioed that he 'was having a little trouble gaining alt.' He then stated that the acft had problems & he didn't know what they were. A stall warning horn was operating as he was transmitting. The acft subsequently crashed in a nose down, left wing low attitude while at a relatively low airspeed. An exam of the eng, acft systems & flt controls revealed no evidence of a failure or malfunction. According to a Lycoming rep, the eng would have been producing a miximum of 79% of its rated power at a density alt of 7089 ft.
