## Analysis

THE PLT REPORTED THAT ON APPROACH HE WAS 'A LITTLE HIGH & HOT' FOR THE 5000-FT-LONG RWY. HE SAID THAT AT MIDFIELD HE WAS 100 FT. AGL & HE DECIDED TO GO AROUND. UPON APPLYING POWER ONLY 700 RPM WAS OBTAINED, SO HE THEN ATTEMPTED TO LAND THE ACFT AT THE END OF THE ARPT. THE ACFT OVERFLEW THE END OF THE PAVEMENT, TOUCHED DOWN IN AN ADJACENT SOFT, DIRT FIELD AND NOSED OVER. THE REASON THE ENGINE ONLY PRODUCED 700 RPM WAS NOT DETERMINED.
