Narrative:

The aircraft was rolling for takeoff. About 2 or 3 seconds after full power was engaged, the centerline of the runway was sliding to the right. Each time I tried to bring the nose of the plane back ot the centerline by applying right rudder pressure, the brakes would engage. Before the action of decreasing the throttle came, the aircraft was already in the grass about 15-20 yrs off the left side of the runway. It wasn't until I turned the engine off and was out looking the plane over when I noticed some damage to the leading edge of the left wing at the very end, where the wing had struck an object next to the runway. Somehow, west/O noticing it, my left foot must have been putting full pressure on the rudder. It could have all been prevented simply by reducing power form the throttle when the aircraft starting turning. Callback conversation with reporter revealed the following: reporter indicated he had a total of 32 hours--3 solo and 3 with the instrument pilot after the incident. When queried as to his technique on takeoff re: torque, the student pilot asked, 'what is torque?' a brief review of the effects of propeller forces and effects on the aircraft during throttle application was done and a further discussion ensued re: feet placement on rudder pedals during takeoff and the situation he had experienced re: brake application during rudder movement. Student felt that the review with the instrument had been helpful. No other actions or agencies were in any form of investigation on this incident.

Title: PLT OF SMA LOSES CTL OF AFT AND IT INCURS A RWY EXCURSION AND STRIKES A WING TIP AGAINST A LIGHT STANCHION OFF THE SIDE OF THE RWY.

Narrative: THE ACFT WAS ROLLING FOR TKOF. ABOUT 2 OR 3 SECS AFTER FULL PWR WAS ENGAGED, THE CENTERLINE OF THE RWY WAS SLIDING TO THE RIGHT. EACH TIME I TRIED TO BRING THE NOSE OF THE PLANE BACK OT THE CENTERLINE BY APPLYING RIGHT RUDDER PRESSURE, THE BRAKES WOULD ENGAGE. BEFORE THE ACTION OF DECREASING THE THROTTLE CAME, THE ACFT WAS ALREADY IN THE GRASS ABOUT 15-20 YRS OFF THE LEFT SIDE OF THE RWY. IT WASN'T UNTIL I TURNED THE ENG OFF AND WAS OUT LOOKING THE PLANE OVER WHEN I NOTICED SOME DAMAGE TO THE LEADING EDGE OF THE LEFT WING AT THE VERY END, WHERE THE WING HAD STRUCK AN OBJECT NEXT TO THE RWY. SOMEHOW, W/O NOTICING IT, MY LEFT FOOT MUST HAVE BEEN PUTTING FULL PRESSURE ON THE RUDDER. IT COULD HAVE ALL BEEN PREVENTED SIMPLY BY REDUCING PWR FORM THE THROTTLE WHEN THE ACFT STARTING TURNING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR INDICATED HE HAD A TOTAL OF 32 HRS--3 SOLO AND 3 WITH THE INSTR PLT AFTER THE INCIDENT. WHEN QUERIED AS TO HIS TECHNIQUE ON TKOF RE: TORQUE, THE STUDENT PLT ASKED, 'WHAT IS TORQUE?' A BRIEF REVIEW OF THE EFFECTS OF PROP FORCES AND EFFECTS ON THE ACFT DURING THROTTLE APPLICATION WAS DONE AND A FURTHER DISCUSSION ENSUED RE: FEET PLACEMENT ON RUDDER PEDALS DURING TKOF AND THE SITUATION HE HAD EXPERIENCED RE: BRAKE APPLICATION DURING RUDDER MOVEMENT. STUDENT FELT THAT THE REVIEW WITH THE INSTR HAD BEEN HELPFUL. NO OTHER ACTIONS OR AGENCIES WERE IN ANY FORM OF INVESTIGATION ON THIS INCIDENT.
