Narrative:

During climb out at 8500 ft, left engine failed indicated by a loud thump and yaw to left, along with rapidly rising temperature indication. Engine was shutdown in accordance with appropriate checklists, emergency was declared with controling facility, and request for return to nearest suitable airport made - bhm. Appropriate checklists were completed, and single engine landing was uneventfully made. Crew coordination was superb! Left engine was now windmilling and causing a very bad vibration so I adjusted the pitch of the propeller using the propeller auxiliary pump and the vibration immediately stopped. The vibration gradually came back as the propeller adjusted itself to its former feathered position. There is no procedure for this, but it did work.
