THE LOCAL FLIGHT ORIGINATED FROM THE SAN ANTONIO INTERNATIONAL AIRPORT AT 1500. THE FLIGHT INSTRUCTOR HAD DEMONSTRATED BASIC FLIGHT MANEUVERS TO THE STUDENT PILOT. THE STUDENT HAD BEEN PRACTICING THE FLIGHT MANEUVERS FOR ABOUT 30-40 MINUTES WHEN THE FLIGHT INSTRUCTOR NOTICED A DROP IN ENGINE RPM AND ALTITUDE. HE INSTRUCTED THE STUDENT PILOT TO APPLY FULL POWER; HOWEVER, THE RPM CONTINUED TO DROP. THE FLIGHT INSTRUCTOR CONFIRMED THAT THE STUDENT HAD APPLIED FULL POWER AND TOOK CONTROL OF THE AIRPLANE.

DURING THE LANDING ROLL, THE NOSE LANDING GEAR SUNK INTO THE SOFT DIRT, AND THE AIRPLANE NOSED OVER COMING TO REST INVERTED.
