Narrative:

20 mi northeast of int'l airport the left engine of the light transport aircraft shut itself down and automatic feathered. The problem arose suddenly with no engine indications of any sort. After talking to the maintenance people I was informed that it was the splines on the shaft of the engine driven fuel pump which had worn down over time. The suggestion they had would be to put that particular engine section, which caused the problem, on a time change program for overhauls. I'd like to mention the ability of the crew in handling this situation which is the result of a good CRM program that the company recently started. Also my commendations to the captain in directing the crew in this situation. Could not have asked for a better crew.
