THE STUDENT PILOT HAD BEEN DOING TOUCH AND GO LANDINGS WHEN THE AIRPLANE'S ENGINE LOST POWER DURING THE TURN TO BASE LEG AT AN ALTITUDE OF 300 FEET AGL. ON FINAL, THE AIRPLANE COLLIDED WITH THE TOP OF THE LOCALIZER ANTENNA LOCATED AT THE END OF THE RUNWAY. ALTHOUGH NO MECHANICAL REASON COULD BE FOUND FOR THE LOSS OF ENGINE POWER, THE STUDENT PILOT STATED THAT ONE OF THE CHARACTERISTICS OF A TWO CYCLE ENGINE IS TO 'LOADUP' AFTER AN EXTENDED TIME AT IDLE POWER. THE LAST CONDITON INSPECTION WAS COMPLETED IN 1991. THE STUDENT PILOT'S AIRMAN CLASS 3 MEDICAL CERTIFICATE/STUDENT PILOT CERTIFICATE HAD EXPIRED AND HAD NOT BEEN ENDORSED FOR SOLO FLIGHT.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE LOSS OF ENGINE POWER DUE TO UNDETERMINED REASONS. FACTORS FOUND TO BE INVOLVED IN THIS ACCIDENT WERE THE CONDITION INSPECTION WAS OVERDUE AND THE INADEQUATE TRAINING RECEIVED BY THE STUDENT PILOT OWNER/BUILDER.
