Narrative:

I am a CFI. A student of mine was cleared to taxi to the active runway, but hold short of another runway. When he was cleared to cross the runway, a miscom occurred. He crossed the active runway instead of taxiing to it. At that time an aircraft was on short final, and was barely able to get the aircraft to go around. If my student had repeated his clearance back to ground control the confusion in his head may have been cleared up before the near disaster. Communications cannot be stressed enough.

Original NASA ASRS Text

Title: STUDENT PLT CROSSES ACTIVE RWY CAUSING A GO AROUND.

Narrative: I AM A CFI. A STUDENT OF MINE WAS CLRED TO TAXI TO THE ACTIVE RWY, BUT HOLD SHORT OF ANOTHER RWY. WHEN HE WAS CLRED TO CROSS THE RWY, A MISCOM OCCURRED. HE CROSSED THE ACTIVE RWY INSTEAD OF TAXIING TO IT. AT THAT TIME AN ACFT WAS ON SHORT FINAL, AND WAS BARELY ABLE TO GET THE ACFT TO GO AROUND. IF MY STUDENT HAD REPEATED HIS CLRNC BACK TO GND CTL THE CONFUSION IN HIS HEAD MAY HAVE BEEN CLRED UP BEFORE THE NEAR DISASTER. COMS CANNOT BE STRESSED ENOUGH.
