A PRINTED CSC DUATS ON THE WEB FLIGHT PLAN WAS FOUND IN THE AIRCRAFT INDICATING THE DEPARTURE POINT OF MONTGOMERY FIELD (MYF) SAN DIEGO CA WITH AN INTENDED FINAL DESTINATION OF FORT LAUDERDALE FL (FXE) WITH STOPS AT LORDSBURG NM (LSB), SNYDER TX (SNK), ADDISON TX (ADS), PINEVILLE LA (2LO) AND QUINCY FL (2J9). A CERTIFICATED FLIGHT INSTRUCTOR (CFI), WITNESS, AND STUDENT, LOCATED IN THE TRAFFIC PATTERN OF THE WILCOX AIRPORT STATED, AS THEY WERE CROSSING MID-FIELD TO ENTER A LEFT DOWNWIND, OBSERVED AN AIRCRAFT APPROACHING FROM THE WEST FOR A STRAIGHT IN APPROACH TO RUNWAY 03. THE CFI AND STUDENT HEARD THE PILOT REPORT ON THE UNICOM HE WAS 3 MILES WEST. THE CFI OBSERVED THE AIRCRAFT APPROACH RUNWAY 03 AND APPEARED TO BE AT A HIGH RATE OF SPEED. THE CFI FURTHER STATED THE AIRCRAFT WAS APPROXIMATELY OVER THE NUMBERS OF RUNWAY 03 WHEN THE AIRCRAFT MADE A HARD STEEP TURN TO THE LEFT TO ENTER AN EARLY CROSSWIND, AND THEN ANOTHER HARD STEEP AGGRESSIVE TURN TO THE LEFT "45-60 DEGREE BANK", TO ENTER A DOWNWIND WHEN HE NOTICED THE AIRCRAFT HAD ENTERED A SPIN TO THE LEFT. DURING THIS PERIOD, THE CFI STATED, A PERSON OF THE AIRCRAFT KEYED THE MIKE AND WAS SCREAMING AND YELLING OVER THE UNICOM. THE CFI COULD NOT UNDERSTAND WHAT THE PERSON WAS SAYING. THE CFI FURTHER STATED, HE COUNTED 2 ½ TURNS OF THE SPIN TO THE LEFT PRIOR TO IMPACTING THE GROUND. THE CFI AND STUDENT RETURNED TO THE AIRPORT AND LANDED.
