## Analysis

STUDENT PLT HAD DEP APT FOR PURPOSE OF PRACTICING LDGS. AT ABOUT 400 FT HE NOTED A PWR LOSS AND ROUGH RUNNING ENG. HE REDUCED THE THROTTLE SETTING AND THE ROUGHNESS CONTD. FURTHER REDUCTIONS WERE MADE TO THE POINT WHERE FLIGHT COULD NOT BE MAINTAINED. THE STUDENT SELECTED A CULTIVATED FIELD AND LANDED THE AIRCRAFT. DURING THE LANDING ROLL THE NOSE GEAR COLLAPSED AND THE ACFT CAME TO A STOP INVERTED. EXAM OF THE ENG REVEALED THAT THE EXHAUST VALVE FOR THE #3 CYLINDER WAS STUCK IN THE OPEN POSITION.
