PILOT STATEMENT:

ON INITIAL APPROACH TO LANDING GOOD LINE UP, GOOD ALTITUDE, FULL TRIM FULL FLAPS. AS APPROACHED  END OF RUNWAY, IT APPEARED A BIT LOW. ADDED A LITTLE POWER WITH MINIMAL RESPONSE, ADDED CONSIDERABLE MORE POWER WHICH WITH FULL TRIM IN THAT AIRCRAFT CAUSED A SUDDEN NOSE HIGH ATTITUDE AND A SUDDEN SLIP TO THE RIGHT WITH IMPACT ON RIGHT SIDE OF GRAVEL. THE OCCUPANTS EXITED THE AIRCRAFT, WHICH THEN IMMEDIATELY CAUGHT FIRE AND BURNED.
