Narrative:
I was flying on an instrument approach (ILS runway 32) to the arcata airport. Arcata had reported a 1200' overcast ceiling with 10 mi visibility. My intention was to execute the ILS approach until reaching VFR conditions underneath the ceiling, then proceed to murray field, VFR, my final destination. I intercepted the localizer in VFR conditions, notified ZSE of this fact and was subsequently cleared for the approach. Somewhere between knees and kurbe intersection I completed my before landing checks, but decided to keep the landing gear retracted because of my decision to eventually break off the approach. During descent on the localizer and G/south somewhere between 4-5 mi DME from arcata airport I noticed the right fuel boost light come on then go off.it then came on again, followed by a power loss in the right engine. As I was executing engine out procedures, the left engine started to surge and then lost power. I attempted to restart each engine but was unsuccessful. I contacted arcata radio, declared an emergency giving my position of 4.2 mi DME on the ILS. In the meantime I established a gliding attitude and landed in a clearcut field where I came to a stop. I immediately evacuated the aircraft and walked to a house nearby where I called my company. Then I called the arcata FSS. The problem arose it seems from a lack of fuel to each engine. Switching tanks was unsuccessful. Callback conversation with reporter revealed the following: reporter states neither NTSB, FAA nor company chose to do an engine tear down, so hard to determine what mechanical failure may be involved. Major structural damage occurred; all 4 fuel tanks ruptured. It has been determine that fuel starvation was not problem as would have had 70 gals available. No enforcement action is being taken.

Title: ON ILS APCH LOST POWER ON 1 ENGINE, THEN THE OTHER. RESTART PROCS ATTEMPTED WITHOUT SUCCESS. MADE EMER LNDG.
Narrative: I WAS FLYING ON AN INSTRUMENT APCH (ILS RWY 32) TO THE ARCATA ARPT. ARCATA HAD RPTED A 1200' OVCST CEILING WITH 10 MI VISIBILITY. MY INTENTION WAS TO EXECUTE THE ILS APCH UNTIL REACHING VFR CONDITIONS UNDERNEATH THE CEILING, THEN PROCEED TO MURRAY FIELD, VFR, MY FINAL DEST. I INTERCEPTED THE LOC IN VFR CONDITIONS, NOTIFIED ZSE OF THIS FACT AND WAS SUBSEQUENTLY CLRED FOR THE APCH. SOMEWHERE BTWN KNEES AND KURBE INTXN I COMPLETED MY BEFORE LNDG CHKS, BUT DECIDED TO KEEP THE LNDG GEAR RETRACTED BECAUSE OF MY DECISION TO EVENTUALLY BREAK OFF THE APCH. DURING DSCNT ON THE LOC AND G/S SOMEWHERE BTWN 4-5 MI DME FROM ARCATA ARPT I NOTICED THE RIGHT FUEL BOOST LIGHT COME ON THEN GO OFF.IT THEN CAME ON AGAIN, FOLLOWED BY A PWR LOSS IN THE RIGHT ENG. AS I WAS EXECUTING ENG OUT PROCS, THE LEFT ENG STARTED TO SURGE AND THEN LOST PWR. I ATTEMPTED TO RESTART EACH ENG BUT WAS UNSUCCESSFUL. I CONTACTED ARCATA RADIO, DECLARED AN EMER GIVING MY POS OF 4.2 MI DME ON THE ILS. IN THE MEANTIME I ESTABLISHED A GLIDING ATTITUDE AND LANDED IN A CLEARCUT FIELD WHERE I CAME TO A STOP. I IMMEDIATELY EVACUATED THE ACFT AND WALKED TO A HOUSE NEARBY WHERE I CALLED MY COMPANY. THEN I CALLED THE ARCATA FSS. THE PROB AROSE IT SEEMS FROM A LACK OF FUEL TO EACH ENG. SWITCHING TANKS WAS UNSUCCESSFUL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR STATES NEITHER NTSB, FAA NOR COMPANY CHOSE TO DO AN ENG TEAR DOWN, SO HARD TO DETERMINE WHAT MECHANICAL FAILURE MAY BE INVOLVED. MAJOR STRUCTURAL DAMAGE OCCURRED; ALL 4 FUEL TANKS RUPTURED. IT HAS BEEN DETERMINE THAT FUEL STARVATION WAS NOT PROB AS WOULD HAVE HAD 70 GALS AVAILABLE. NO ENFORCEMENT ACTION IS BEING TAKEN.
