Narrative

AFTER ENG START; TAXI WAS COMMENCED; ACFT WAS TAXIED UP ONTO A HELI LNDG PAD. THE ENG WAS TURNED OFF. THERE WAS NO PROP STRIKE. THE ONLY DAMAGE WAS TO THE FIBERGLASS WHEEL PART (R SIDE). THE STUDENT WAS SITTING IN THE FRONT SEAT; AND HAS FORWARD VISIBILITY. INSTRUCTOR IN THE BACK SEAT HAS NONE. CAUSE: FAILURE UPON THE STUDENT'S PART TO HAVE VISUAL CONTACT WITH THE PAD. FAILURE UPON INSTRUCTOR'S PART TO INSURE TXWY WAS CLR. EVEN THOUGH HELI PAD HAD NOT MOVED FOR 3 HRS PRIOR. CORRECTION: BETTER SITUATIONAL AWARENESS UPON STUDENT AND CFI. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: INSTRUCTOR PLT VERIFIED THAT THE ACFT WAS A TAIL DRAGGER CITABRIA AND THEY WERE DEPARTING VNY ARPT. THE ACFT BELONGED TO THE STUDENT AND RPTR INSTRUCTOR SAYS SHE WAS EXCITED ABOUT HER NEW ACFT AND WAS A LITTLE NERVOUS AND ANXIOUS. THERE WAS A ROW OF PARKING SPOTS FOR HELI'S DIRECTLY IN FRONT OF THEIR ACFT AND HE DIDN'T KNOW WHY THE STUDENT TAXIED STRAIGHT AHEAD INSTEAD OF TURNING TO FOLLOW THE TAXI LINE. RPTR SAYS BOTH OF THE FLC SHOULD HAVE HAD BETTER SITUATIONAL AWARENESS AND THAT HE SHOULD HAVE BRIEFED THE STUDENT BEFORE GETTING INTO THE ACFT ABOUT THE TAXI RTE; ETC. ALSO; THAT HE SHOULD HAVE PAID MORE ATTN TO WHAT WAS IN FRONT OF THEIR ACFT BEFORE GETTING INTO THE REAR COCKPIT. HE SHUT OFF THE MAGNETOS AS SOON AS HE FELT THE ACFT BUMP WHEN IT HIT THE HELI PAD.
