AN MD83 IN DSCNT AT 14000 FT DECLARED AN EMER DUE TO #1 ENG OIL STRAINER CLOG WARNING LIGHT ILLUMINATED. ENG OPERATED AT IDLE.

Narrative

IN THE DSCNT TO SEA; ABOUT 14000 FT; A 'L ENG OIL STRAINER CLOG' LIGHT CAME ON IN THE OVERHEAD PANEL. I CHKED THE QRH AND THE PROC CALLED FOR PULLING THE L ENG TO IDLE. THE LIGHT WENT OUT FOR A WHILE; BUT CAME ON AGAIN A FEW MINS LATER AND STAYED ON UNTIL LNDG. THE PROC REQUIRES THAT THE ENG BE OPERATED IN IDLE AND THAT IF THE OIL TEMP AND PRESSURE RISE; THEN ENG SHOULD BE SHUT DOWN. I DECLARED AN EMER WITH APCH SO THAT WE COULD GET PRIORITY TO THE FIELD; AND TO LET THEM KNOW THAT WE WERE OPERATING 1 ENG IN IDLE AND COULD POSSIBLY HAVE AN INFLT SHUTDOWN. WE LANDED; SHUT DOWN THE L ENG AND TAXIED TO THE GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ENG OIL STRAINER WAS REMOVED AND CLEANED. THE RPTR SAID THE SCREENS WERE PLUGGED WITH CARBON PARTICLES BUT NO METAL WAS FOUND. THE RPTR STATED THE OIL STRAINER WAS REINSTALLED AFTER CLEANING AND THE ENG RUN AT PART IN PWR AND OPERATED NORMALLY. THE RPTR SAID A DEFERRED ITEM WAS ENTERED FOR A 25 HR STRAINER RECHK. THE RPTR STATED THE ENG WAS A PRATT & WHITNEY JT8D-219.
