Incident Overview
On January 21, 2015, a Piper PA-31 (registration LV-JGW) experienced an engine issue while climbing from Aeropuerto Internacional de Laguna del Sauce (SULS) in Uruguay to Aeropuerto Internacional de San Fernando (SADF) in Argentina. The aircraft was carrying two pilots and four passengers.
Flight Details
During the climb from 1500 feet to 8000 feet, the crew felt a slight vibration followed by a decrease in oil pressure on engine No. 1 (left engine). The crew reduced power on the affected engine and observed oil loss on the left engine cowling. They then feathered the propeller and shut down the engine.
Crew Actions
After securing the engine, the crew decided to return to SULS. The aircraft landed without any further incidents.
Inspection Findings
Subsequent inspection of the left engine revealed a hole in the engine block. The Uruguayan aviation investigation authority (CIAIA) classified the event as neither an accident nor a serious incident based on the damage observed.
