## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THE AIRCRAFT WAS FLYING AROUND THE BAY AREA DOING AERIAL PHOTOGRAPHY.  THE PILOT REPORTED OIL PRESSURE LOSS AND THE ENGINES SUDDENLY WENT QUIET AT 1,500 FEET OVER THE WATER OFF EMERYVILLE, CA.  THE PIC SAID HE TRIED TO GLIDE TO ALAMEDA TO LAND, BUT DIDN'T MAKE IT.  THE CE-210 SPLASHED DOWN 500 YARDS FROM SHORE JUST NORTH OF THE BAY BRIDGE WITH THE GEAR IN THE UP POSITION.  AS IT TURNED OUT, THE COAST GUARD, ALAMEDA COUNTRY SHERIFF'S DEPARTMENT AND THE OAKLAND POLICE DEPARTMENT HAD A TOTAL OF SIX BOATS CONDUCTING A DRILL, AND ALL WERE LESS THAN TWO MILES FROM WHERE THE PLANE WENT DOWN.  THE MEN WERE STANDING ON THE WING OF THE SUBMERGED PLANE, AND ONLY THE TAIL WAS STILL VISIBLE ABOVE THE WATER WHEN HELP ARRIVED.  THE MEN WERE TRANSPORTED ON YERBA BUENA ISLAND BY THE COAST GUARD.  PILOT LOGBOOKS WERE LOST IN THE BAY.  INITIAL INSPECTION REVEALED A 1-INCH HOLE IN THE ENGINE CASEHALF ABOVE THE NUMBER 1 CYLINDER.  THE CRANKSHAFT BROKE IN HALF CAUSING A HOLE IN THE CASE.
