SHORTLY AFTER THE PLT DEPARTED ON A FLT, THE ENG LOST POWER WHILE THE ACFT WAS CRUISING AT 1800 FT MSL OVER HILLY TERRAIN. THE PLT REPORTED THAT THE ENG SPEED DROPPED TO 800 RPM & HE WAS UNABLE TO CORRECT THE SITUATION. DURING A FORCED LANDING ON SOFT TERRAIN, THE ACFT ENCOUNTERED A DITCH & NOSED OVER.
