Analysis
The acft tookoff from an arpt whose rwys had been closed for snow removal. A NOTAM had been filed with the fresno fss by the Mammoth lake arpt mgr at 0900 hrs for taxi and rwy snow removal. The plt was aware of the NOTAM because the mgr and a lineman both said they advised him of it. Several witnesses saw the plt enter the acft after declining eng pre-heat or acft de-icing. When advised by the lineman that the 2 qts of oil that the plt requested did not 'register onthe dip-stick.' The plt ordered another qt to be 'thrown' in & 'hurry up.' No pre-flt or warm up or before takeoff check was noted by observers. Turning immediately onto the rwy and rolling for takeoff the plt passed a snow plow. The acft used 7000 ft (all of the rwy) and left the ground in a nose high attitude. The arpt elevation is 7128 ft MSL. The acft first struck a dirt mound 3/4 of a mile after takeoff. After maintaining further flt for aprx 280 ft which crossed a small ravine the acft collided with the FAR side of the ravine & started to break apart, stopping 144 ft further east.
