DURING A DAY CROSS COUNTRY FLIGHT, THE STUDENT PILOT BEGAN AN APPROVED DESCENT FOR AN APPROACH TO SAN ANTONIO INTERNATIONAL AIRPORT, SAN ANTONIO, TEXAS, THE ENGINE LOST PARTIAL POWER DUE TO A STUCK VALVE IN THE NUMBER 2 CYLINDER STUDENT PILOT WAS VECTORED TO A PRIVATE AIRSTRIP, HOWEVER, SHE COULD NOT EXTEND THE GLIDE FAR ENOUGH TO REACH THE AIRSTRIP DUE TO A TAIL WIND ON HER SELECTED FINAL APPROACH COURSE. THE AIRPLANE STRUCK A TREE AND FENCE DURING THE LANDING CAUSING THE AIRPLANE TO PITCH OVER INVERTED. SIGNIFICANT MAINTENANCE HAD BEEN PERFORMED PRIOR TO THE FLIGHT AND THERE WAS AT LEAST ONE INSTANCE OF A POWER LOSS DURING A PREVIOUS TAKEOFF.
