Analysis

THE PILOT WAS RETURNING TO HIS HOME AIRPORT FLYING VFR A 1500 FEET MSL. AFTER STARTING A SLOW CLIMB TO 3000 FEET THE PILOT NOTICED THE PROPELER RPM HAD DROPPED ON THE RIGHT ENGINE AND HIS PASSENGER TOLD HIM THAT OIL WAS LEAKING FROM THE ENGINE. THE PILOT SHUT DOWN & FEATHERED THE RIGHT ENGINE. HE COULD NOT MAINTAIN ALTITUDE OR AIRSPEED ON THE LEFT ENGINE, SO HE ELECTED TO MAKE AN OFF AIRPORT LANDING ON A CLOSED HIGHWAY. WHILE ON APPROACH, THE LEFT PROPELLER STRUCK A POWERLINE. THE PILOT COULD NOT GAIN CONTROL OF THE AIRPLANE BEFORE IT IMPACTED THE GROUND. THE ENGINE TEARDOWN SHOWED NO DISCREPANCIES. THE POST IMPACT FIRE CAUSED TOO MUCH DAMAGE TO THE OIL LINES & ENGINES EXTERIOR TO DETERMINE THE ORIGIN OF THE OIL LEAK.
