## Analysis (aircraft 2)

THE PLT OF THE GRUMMAN G-164A, N952X, REPORTED THAT AFTER THE ACFT WAS LOADED & FUELED, HE STARTED TO TAXI NORTHBOUND ON A TAXIWAY FROM THE RAMP TO THE RWY. AT ABOUT THE SAME TIME, A STUDENT PLT IN A CESSNA 152, N67449, HAD LANDED ON THE RWY & TURNED SOUTHBOUND ONTO THE TAXIWAY. THE STUDENT SAW THE G-164 & STOPPED ON THE RIGHT SIDE OF THE RWY. HOWEVER, THE PILOT OF THE G-164A DID NOT SEE THE CESSNA & CONTINUED NORTHBOUND. SUBSEQUENTLY, THE G-164A COLLIDED WITH THE CESSNA, DAMAGING THE LEFT WING OF EACH ACFT. THERE WAS NO UNICOM TRANSMISSION FROM EITHER PLT.
