Narrative:

The student was having problems maintaining runway centerline so we practiced low approachs over the runway in order to enable him to maintain centerline. On the second time around we were approximately 10 ft over the runway when he allowed the aircraft to yaw right. This aimed us directly at some trees. I took control of the aircraft and established us back over the runway, however, in the distraction we did not leave adequate distance ahead of the aircraft to perform a normal go around. Thus we were only approximately 100 ft when we crossed over a road at the end of the runway. Contributing factors I believe were the student's hesitation to release the aircraft to me when I said 'my aircraft.' I feel that in the future I will be more selective in allowing certain students to practice at certain airports and emphasize the importance of relinquishing the controls to the instructor in a timely fashion.

Original NASA ASRS Text

Title: J3 INSTRUCTOR AND TRAINEE LOST ACFT CTL WHILE EXECUTING A MISSED APCH.

Narrative: THE STUDENT WAS HAVING PROBS MAINTAINING RWY CTRLINE SO WE PRACTICED LOW APCHS OVER THE RWY IN ORDER TO ENABLE HIM TO MAINTAIN CTRLINE. ON THE SECOND TIME AROUND WE WERE APPROX 10 FT OVER THE RWY WHEN HE ALLOWED THE ACFT TO YAW R. THIS AIMED US DIRECTLY AT SOME TREES. I TOOK CTL OF THE ACFT AND ESTABLISHED US BACK OVER THE RWY, HOWEVER, IN THE DISTR WE DID NOT LEAVE ADEQUATE DISTANCE AHEAD OF THE ACFT TO PERFORM A NORMAL GAR. THUS WE WERE ONLY APPROX 100 FT WHEN WE CROSSED OVER A ROAD AT THE END OF THE RWY. CONTRIBUTING FACTORS I BELIEVE WERE THE STUDENT'S HESITATION TO RELEASE THE ACFT TO ME WHEN I SAID 'MY ACFT.' I FEEL THAT IN THE FUTURE I WILL BE MORE SELECTIVE IN ALLOWING CERTAIN STUDENTS TO PRACTICE AT CERTAIN ARPTS AND EMPHASIZE THE IMPORTANCE OF RELINQUISHING THE CTLS TO THE INSTRUCTOR IN A TIMELY FASHION.
