Narrative:
While at cruise at FL190, I heard a thump in the left engine. I then started losing torque and was unable to maintain altitude. Therefore, I went below my assigned altitude. I then was cleared direct to the srb airport. I did not declare an emergency because the loss was not severe enough to warrant declaring an emergency. I landed with no incident.
