During the takeoff roll portion of a touch-and-go, the airplane veered off the runway and collided with a taxiway sign. The CFI said the first two circuits around the traffic pattern were uneventful, and the student performed satisfactorily. During the third touch-and-go landing the student indicated that the airplane turned right without his application of right rudder pressure. The CFI responded by instructing her student in the proper usage of the rudder pedal. The flight continued around the traffic pattern. The student then performed a normal power on approach with 30 degrees of wing flaps extended for another touch-and-go landing. The touchdown was not hard, and no vibrations or unusual noises were noted. As the student increased the engine power to takeoff and was raising the wing flaps, the airplane again started an uncommanded right turn. The student told the CFI to take control of the airplane and she immediately took the controls and applied left rudder to redirect the airplane back onto the runway. The CFI said that when she pushed on the left pedal the airplane veered even more toward the right, and it collided with a taxiway sign. Thereafter, the CFI elected to continue the takeoff, full engine power was developed, and the airplane took off. During the climb out both pilots had difficulty maintaining control of the airplane. The CFI made an emergency landing at the airport on runway 30. The touchdown, rollout, and taxi to parking were accomplished by the CFI without difficulty. No unusual sounds, vibrations, or braking problems were noted. All of the tires remained inflated and an exhaustive examination of the control system, nose wheel steering mechanism and brakes/tires found no evidence of an anomaly. A series of low and high-speed taxi tests up to 55 knots were performed with the accident airplane under the supervision of FAA Inspectors and the airplane operated normally with no difficulty maintaining directional control. Cessna Aircraft Company personnel subsequently performed a ground steering test on an exemplar airplane to determine the nose gear operating characteristics as the nose gear (tire) is lifted off the ground. When the nose strut extends to the point where the tire is no longer resting on the ground, the strut/wheel is designed to center and lock out rudder pedal steering. The test results noted three specific pitch attitudes: 1) with the center of the leading edge of the elevator approximately 34 inches above the ground, the nose wheel is on the ground, and the strut and wheel turn when the rudder pedals were operated; 2) When the center of the leading edge of the elevator is 29.5 inches above the ground, the nose tire is just touching the ground, and the nose wheel does not turn with application of rudder pedals; 3) when the center of the leading edge of the elevator was about 16 inches above the ground (tailcone tiedown also contacting the ground), the nose wheel was also off the ground and would not move using the ruder pedals. The FAA reported that the top of the "J2" sign was about 34 inches above ground level. In a normal 3-point resting attitude the airplane's elevator is about 41 inches above ground level . To contact the top of the taxiway sign, a Cessna T182T needs to pitch upward such that its elevator lowers 7 inches.
Probable Cause: The student's failure to maintain directional control and the instructor's inadequate supervision of the flight by his delayed remedial action.
