Narrative:
While practicing single engine maneuvers near ccr airport, the right engine was intentionally shut down to simulate an engine failure. After completing the shutdown checklist, an engine restart was attempted on the right engine. The right propeller would not come out of feather, due to a possible accumulator failure, which normally assists the propeller out of feather. After several attempts to bring the right propeller out of feather (all of which were successful) it was decided by the CFI to return to concord airport and land on the operating left engine. The right engine was secured and shut down. We landed without any further event and taxied back to the FBO with the left engine operating normally.

Title: AN ATP CANDIDATE RPTED THAT, DURING THE COMPLETION OF A SIMULATED ENG OUT MANEUVER, THE R PROP WOULD NOT COME OUT OF FEATHER. HE AND HIS CFII MEI LANDED AT CCR, ON THE L ENG, WITHOUT INCIDENT.
Narrative: WHILE PRACTICING SINGLE ENG MANEUVERS NEAR CCR ARPT, THE R ENG WAS INTENTIONALLY SHUT DOWN TO SIMULATE AN ENG FAILURE. AFTER COMPLETING THE SHUTDOWN CHKLIST, AN ENG RESTART WAS ATTEMPTED ON THE R ENG. THE R PROP WOULD NOT COME OUT OF FEATHER, DUE TO A POSSIBLE ACCUMULATOR FAILURE, WHICH NORMALLY ASSISTS THE PROP OUT OF FEATHER. AFTER SEVERAL ATTEMPTS TO BRING THE R PROP OUT OF FEATHER (ALL OF WHICH WERE SUCCESSFUL) IT WAS DECIDED BY THE CFI TO RETURN TO CONCORD ARPT AND LAND ON THE OPERATING L ENG. THE R ENG WAS SECURED AND SHUT DOWN. WE LANDED WITHOUT ANY FURTHER EVENT AND TAXIED BACK TO THE FBO WITH THE L ENG OPERATING NORMALLY.
