Narrative:
Just prior to descending out of 17,000 feet for 10,000 feet, the crew felt a thud and they noticed the #1 low gear box oil pressure light illuminate. The left engine was shut down and the crew declared an emergency. The aircraft continued to Seattle, where it made an uneventful landing on runway 16L.
A subsequent examination by company maintenance personnel indicated that the #1 engine drive shaft had failed at the universal joint connection area on the gear side of the engine, resulting in substantial damage to the firewall.

PROBABLE CAUSE: "The failure of the accessory drive shaft due to deterioration of bearing number 1 in the aft fork of the universal joint for undetermined reasons during cruise flight."
