Narrative:

Following a normal approach in calm winds the small aircraft touched down and immediately veered to the right. The student pilot stated that after a normal touchdown the aircraft yawed rapidly to the right. The student applied opposite rudder and brake but was unable to prevent the aircraft from running off the side of the runway. I am the above pilot's flight instructor. The incident, which was a local solo flight, was related to me by the pilot of the aircraft and by other eyewitnesses. All stated that conditions were calm and the approach and landing appeared normal until just after touchdown. The student pilot has flown over 50 hours in the small aircraft and has become quite proficient at takeoffs and lndgs, and has always demonstrated good judgement in handling the aircraft. A possible stuck brake was suggested, but could not be proven on later inspection of the aircraft, which was not damaged.

Original NASA ASRS Text

Title: RWY EXCURSION.

Narrative: FOLLOWING A NORMAL APCH IN CALM WINDS THE SMA TOUCHED DOWN AND IMMEDIATELY VEERED TO THE R. THE STUDENT PLT STATED THAT AFTER A NORMAL TOUCHDOWN THE ACFT YAWED RAPIDLY TO THE R. THE STUDENT APPLIED OPPOSITE RUDDER AND BRAKE BUT WAS UNABLE TO PREVENT THE ACFT FROM RUNNING OFF THE SIDE OF THE RWY. I AM THE ABOVE PLT'S FLT INSTRUCTOR. THE INCIDENT, WHICH WAS A LCL SOLO FLT, WAS RELATED TO ME BY THE PLT OF THE ACFT AND BY OTHER EYEWITNESSES. ALL STATED THAT CONDITIONS WERE CALM AND THE APCH AND LNDG APPEARED NORMAL UNTIL JUST AFTER TOUCHDOWN. THE STUDENT PLT HAS FLOWN OVER 50 HRS IN THE SMA AND HAS BECOME QUITE PROFICIENT AT TKOFS AND LNDGS, AND HAS ALWAYS DEMONSTRATED GOOD JUDGEMENT IN HANDLING THE ACFT. A POSSIBLE STUCK BRAKE WAS SUGGESTED, BUT COULD NOT BE PROVEN ON LATER INSPECTION OF THE ACFT, WHICH WAS NOT DAMAGED.
