## Analysis

THE STUDENT PLT REPORTED THAT AFTER THE ACFT TOUCHED DOWN ON A TOUCH-&-GO LANDING, HE OBSERVED ABOUT 1000 BIRDS AT THE DEPARTURE END OF THE RWY. HE ELECTED TO TURN OFF AT THE 1ST AVAILABLE TAXIWAY. HOWEVER, HIS SPEED WAS TOO FAST TO NEGOTIATE THE TURN & THE ACFT WENT OFF THE HARD SURFACE & ONTO THE GRASS. THE NOSE GEAR SANK INTO SOFT, WET TERRAIN & THE ACFT STOPPED IN A NOSE DOWN ATTITUDE. ABOUT 8 TO 10 SEC LATER, THE WIND BLEW THE ACFT OVER. THE PLT HAD LANDED WITH A QUARTERING TAIL WIND.
