DURING FLT, THE PLT NOTED THAT OIL PRESSURE IN THE RGT ENG HAD DROPPED TO THE RED LINE, SO HE SHUT DOWN & FEATHERED THE ENG. HE STATED THAT AFTER ENTERING TRAFFIC TO LND, HE 'LOWERED' THE GEAR, THEN NOTED THAT THE RADAR & RADIOS BECAME INOP (AS ELECTRICAL POWER WAS LOST). THOUGH HE HEARD & FELT THE GEAR EXTEND, HE DID NOT SEE ILLUMINATION OF THE DOWNLOCK LIGHTS. THE PLT MADE A 360 DEG TURN TO GET SPACING BEHIND ANOTHER ACFT, THEN CONTD THE APCH TO LAND. DURING THE LANDING, THE GEAR COLLAPSED & THE ACFT WAS DAMAGED. AN EXAM OF THE RGT ENG REVEALED THAT THE LOW OIL PRESSURE WAS DUE TO A PIECE OF CARBON UNDER THE OIL PRESSURE RELIEF VALVE SEAT. BOTH ALTERNATORS TESTED SATISFACTORILY; HOWEVER, BOTH VOLTAGE REGULATORS HAD FAILED INTERNALLY & BOTH ALTERNATOR CIRCUIT BREAKERS WERE POPPED.
Probable Cause: FAILURE OF THE PILOT TO PERFORM THE EMERGENCY GEAR EXTENSION PROCEDURE TO ASSURE THAT THE GEAR WAS DOWN AND LOCKED. FACTORS RELATED TO THE ACCIDENT WERE: LOW OIL PRESSURE IN THE RIGHT ENG, FAILURE OF BOTH VOLTAGE REGULATORS, AND THE LOW LEVEL OF CHARGE IN THE BATTERY.
