## Analysis

THE PILOT SAID HE WAS PRACTICING WATER LANDINGS IN THE LAKE.DURING A LANDING, THE AIRPLANE STARTED PORPOISING DUE TO THE WAKE OF A PASSING BOAT. THE AIRPLANE LANDED HARD. THE WINDSHEILD CRACKED AND THE PILOT ELECTED TO TAKE THE AIRPLANE TO THE HOME AIRPORT FOR FINAL LANDING. UPON ARRIVAL AT THE AIRPORT, THE NOSE GEAR DOORS WOULD NOT OPEN. THE PILOT ELECTED TO LAND WITH ONLY THE MAIN GEAR EXTENDED AND THE NOSE GEAR RETRACTED. AS THE AIRPLANE SLOWED DOWN AFTER LANDING, THE NOSE OF THE AIRPLANE CAME TO REST ON THE RUNWAY.
