## Analysis

THE PURPOSE OF THE FLT. WAS TO CHECK OUT THE 11800 HOUR FORMER NAVAL AVIATOR WHO STATED HE HAD PREVIOUS EXPERIENCE IN T-34B'S. THE CFI, WHO HAD OVER 3000 HOURS, 173 IN MAKE AND MODEL BUT LESS AS AN INSTRUCTOR, STATED HE BRIEFED THE STUDENT ON PROCEDURES AND AIRCRAFT SPEEDS BEFORE THE FLIGHT BUT HAD NEVER PRACTICED CHANGE OF CONTROL COORDINATION WITH HIM. AFTER LIFTOFF THE CFI NOTED THE AIRCRAFT CLIMB AT A STEEPER ANGLE THAN NORMAL AND AT AN AIRSPEED BELOW 70 KNOTS. AS THEY CLIMBED THROUGH 400-500 FEET HE NOTICED A PRE-STALL BUFFET WHICH CONTINUED AS THE RED STALL WARNING LIGHT CAME ON AND HE ATTEMPTED TO TAKE THE CONTROLS. HE IMMEDIATELY RETRACTED THE GEAR BUT AFTER NOTICING THAT THE STUDENT FAILED TO RELEASE THE CONTROLS AND A FULL STALL CONDITION EXISTED, HE LOWERED THEM BEFORE CONTACTING THE GROUND.
