## Analysis

THE PLT LIFTED OFF THE RWY TOO EARLY FOR THE CONDITIONS IE; HIGH GROSS WEIGHT AND ROUGH, UPHILL RWY WITH GRASS FOUR TO SIX INCHES TALL. HE THEN ATTEMPTED TO CLIMB TOO STEEPLY AND STALLED IMMEDIATELY AFTER PASSING THROUGH GROUND EFFECT. THE ACFT DESCENDED STRIKING THE RIGHT WING TIP AND RIGHT MAIN GEAR ON THE SURFACE OF THE RWY. THE GEAR WAS IN TRANSIT. THE DOORS OF THE LEFT MAIN AND NOSE GEARS WERE TORN OFF. THE ACFT ROTATED ABOUT 90 DEGS TO THE RIGHT, SLID OFF THE END OF THE RWY, DOWN AN EMBANKMENT AND INTO TREES.
