Analysis

THE STUDENT PILOT WAS IN THE LEFT SEAT; HIS FATHER, A COMMERCIAL PILOT (NOT AN INSTRUCTOR), WAS IN THE RIGHT SEAT. WHEEL BRAKE PEDALS WERE INSTALLED ON THE LEFT SIDE ONLY. THE STUDENT WAS LANDING THE AIRPLANE. UPON TOUCHDOWN, THE TAIL WHEEL BEGAN TO SHIMMY, AND THE AIRPLANE DRIFTED TO THE SIDE OF THE RUNWAY.
