Narrative:

(Reached cruising altitude of 11,000' and 5 mi from dubuque on way to oshkosh.) noticed oil streaming from left engine, checked oil pressure and saw low psi on gauge (not in green). Reduced power and oil continued to stream. Called center and asked to return to cedar rapids. Shut down left engine and upon calling cedar rapids approach, I asked for a long approach to set up landing with plenty of time. Lowering to FAF and 2700' for ILS 27, I connected autoplt to get approach plate. Level at 2700' caused autoplt to trim nose high to remain level. While continuing inbound on ILS, we encountered a stall buffet and turned left of course. I applied corrections to remain on course and took seconds to respond to nose high trim which I corrected. Approach (tower) gave verbal corrections to ILS. Came over airport left of runway 27, which I could not see. Noticed runway to my left and proceeded with a sharp left turn with another right turn to line up with runway. With airspeed low and altitude low, I could not safely make the runway, landed on grass to left of runway, with the impact removing the landing gear. No one was injured. (With current conditions, a go around might not have been possible.)

Title: SMT TWIN SINGLE PLT IFR SHUT DOWN LEFT ENGINE ACCOUNT OIL LEAK. MADE SINGLE ENGINE INSTRUMENT APCH TO 200'. CEILING 1 MILE VISIBILITY. BROKE OUT OF OVERCAST, DISORIENTED LANDED OFF RWY. WIPED OUT LNDG GEAR.

Narrative: (REACHED CRUISING ALT OF 11,000' AND 5 MI FROM DUBUQUE ON WAY TO OSHKOSH.) NOTICED OIL STREAMING FROM LEFT ENGINE, CHECKED OIL PRESSURE AND SAW LOW PSI ON GAUGE (NOT IN GREEN). REDUCED POWER AND OIL CONTINUED TO STREAM. CALLED CENTER AND ASKED TO RETURN TO CEDAR RAPIDS. SHUT DOWN LEFT ENGINE AND UPON CALLING CEDAR RAPIDS APCH, I ASKED FOR A LONG APCH TO SET UP LNDG WITH PLENTY OF TIME. LOWERING TO FAF AND 2700' FOR ILS 27, I CONNECTED AUTOPLT TO GET APCH PLATE. LEVEL AT 2700' CAUSED AUTOPLT TO TRIM NOSE HIGH TO REMAIN LEVEL. WHILE CONTINUING INBND ON ILS, WE ENCOUNTERED A STALL BUFFET AND TURNED LEFT OF COURSE. I APPLIED CORRECTIONS TO REMAIN ON COURSE AND TOOK SECONDS TO RESPOND TO NOSE HIGH TRIM WHICH I CORRECTED. APCH (TWR) GAVE VERBAL CORRECTIONS TO ILS. CAME OVER ARPT LEFT OF RWY 27, WHICH I COULD NOT SEE. NOTICED RWY TO MY LEFT AND PROCEEDED WITH A SHARP LEFT TURN WITH ANOTHER RIGHT TURN TO LINE UP WITH RWY. WITH AIRSPEED LOW AND ALT LOW, I COULD NOT SAFELY MAKE THE RWY, LANDED ON GRASS TO LEFT OF RWY, WITH THE IMPACT REMOVING THE LNDG GEAR. NO ONE WAS INJURED. (WITH CURRENT CONDITIONS, A GO AROUND MIGHT NOT HAVE BEEN POSSIBLE.)
