WHILE CRUISING AT ABOUT 2000 FT, THE TOP ENG COWLING CAME OFF, RUPTURING AN ENG OIL LINE & BREAKING A HOLE IN THE LEFT SIDE OF THE WINDSHIELD. OIL THEN COVERED THE WINDSHIELD. DUE TO THE LOSS OF OIL, THE PLT SHUT DOWN THE ENG & LANDED ON A BEACH. DURING THE LANDING ON SOFT TERRAIN, THE NOSE GEAR COLLAPSED. THE PLT SUSPECTED THAT THE RIGHT FRONT COWLING LATCH HAD FAILED.
