Analysis

Left engine lost power after takeoff. Pilot feathered left engine and returned to runway on one engine. Since he was overshooting he elected to land on grass wheels up to avoid overrun and collision with ditch. The following discrepancies were found: exhaust valve leak #4 cyl; #1 cyl top plug gap 0.000; #1 cyl lower ignition lead internally shorted; #5 cyl spark plugs loose; #2 cyl lower ignition lead shield broken & ignition wire exposed; #4 cyl lower ignition lead cigarette spring cut & stretched; #2,4 & 6 cyl upper ignition leads showed occasional open; and r/h mag "p" lead intermittently grounded internally at mag connection.
