Narrative:The no. 1 engine low oil pressure warning light came on while climbing through 7000 feet. When the engine was stopped, a fuse blew and only the right side instruments lights functioned. The crew returned to the airport and preformed an ILS approach. The prop hadn't feathered so rudder and elevator were fully deflected. The aircraft touched down 30 m left of the runway.
Probable cause: (translated from Swedish)
Due to the fact that left propeller did not go to feathering mode, a drag arose which the pilot could not compensate with trim and rudder, so that the aircraft landed on the side of the runway.
Contributing factors:
- Oil leakage in the engine which made it necessary to stop the left engine and feather the propeller.
- Power supply problems caused by the left side not having been isolated from the right side.
- A misrigged feathering handle
- Inadequate checklists.
