Analysis

Acft was observed taking off downwind on an uphill gradient rwy. The acft rotated several times before lifting off into a 40-45 deg angle of climb & stalling. The takeoff roll was started abeam the runup pad which provided 3,500 ft for takeoff. An additional 700 ft of blacktop & 1,300 ft of usable dirt rwy was available south of the runup pad. The density altitude was computed to be 9,887 ft. flaps were not used. Performance data from the manufacturer using figures for a M20J (higher performance acft) showed that under the existing conditions & using takeoff flaps of 15 deg approximately 2,406 ft would be required for the takeoff roll with an additional 15,983 ft required to clear a 50 ft obstacle.
