C152 INSTRUCTOR PLT AND STUDENT TAXIED BEHIND A BE30 AND WAS BLOWN OVER.

Narrative

WHILE CONDUCTING A TRAINING FLT AS A CFI AT PYM; THE STUDENT AND I HAD BEGUN DOING TKOFS AND LNDGS. AFTER THE STUDENT LANDED THE ACFT ON THE RWY; THE AIRPLANE ROLLED OUT ABOUT 800 FT OR SO AND WE EXITED AT THE NEXT TXWY. UPON XING THE HOLD SHORT LINES IT WAS EVIDENT THAT WE WERE CAUGHT IN THE PROP BLAST OF A KING AIR THAT WAS SITTING ON THE RAMP AREA ADJACENT TO THE TXWY. I IMMEDIATELY HAD THE STUDENT APPLY XWIND CORRECTION WITH THE AILERONS INTO THE DIRECTION OF THE KING AIR. THE KING AIR WAS ANGLED SO THAT ITS PROP WASH WAS POINTED DIRECTLY AT THE TXWY. I TOLD THE STUDENT TO ATTEMPT TO TAXI THE ACFT CLR OF THE PROP WASH. HE ADDED PWR TO TRY THIS HOWEVER WITHIN A COUPLE SECONDS THE PROP BLAST FROM THE KING AIR LIFTED THE CESSNA 152 WE WERE IN OFF OF THE PAVEMENT. I BELIEVE WE WERE OFF THE PAVEMENT FOR A MOMENT OR TWO BEFORE THE ACFT SETTLED BACK DOWN ONTO THE PAVEMENT WITH THE R WINGTIP AND PROP TOUCHING THE GND. THE WINDS AT THE TIME WERE OUT OF THE WSW AT 17 KTS GUSTING TO 24 KTS. I BELIEVE THESE WINDS ADDED TO THE INCIDENT OCCURRING. I BELIEVE HAD THE KING AIR BEEN DOING A RUN-UP OF THE ENGS EITHER OFF OF THE RAMP AREA; NOT POINTED AT A TXWY AND OR AT AN AREA OF THE ARPT AWAY FROM TAXIING ACFT THIS INCIDENT WOULD NOT HAVE HAPPENED. THE KING AIR WAS APPROX 50 YARDS AWAY FROM THE HOLD SHORT LINES OF THE TXWY.
