Narrative:

After departing pit, the left oil strainer clogging light illuminated! We completed the appropriate abnormal checklist which led us to a precautionary engine shutdown. An emergency was declared and we returned to pit. Total flight time was approximately 15 min with single engine time of approximately 5 min. Upon reading the gate in pit, the filter was checked for contamination and none was found.
