AN MD80 IN CLB DECLARED AN EMER AND DIVERTED DUE TO COMPLETE LOSS OF OIL PRESSURE AND QUANTITY ON #1 ENG.

Narrative

DURING CLB OUT OF STL AT APPROX FL280; WE LOST OIL PRESSURE ON THE L ENG (LIGHT CAME ON) QUANTITY SHOWED ZERO PRESSURE FAILING AND TEMP RISING REFERRED TO OUR INFLT HANDBOOK AND IMMEDIATELY DECLARED AN EMER AND SHUT DOWN THE L ENG WHILE TURNING TO RETURN TO STL. THE COPLT HELPED ME COORDINATE WITH ACR DISPATCH; STL RAMP; CHANGE DEST TO STL IN ACARS. SINCE WE WERE SO CLOSE TO STL; THE DSCNT WAS NEAR IDLE PWR UNTIL ABEAM THE ARPT. WE ACCOMPLISHED ALL THE APPROPRIATE CHKLISTS AND MADE AN UNEVENTFUL EMER LNDG ON RWY 30L AT STL. WROTE UP THE L ENG AND OVERWT LNDG (SMOOTH) IN THE LOGBOOK. I BELIEVE THAT ALL THE TRAINING THE COPLT AND MYSELF RECEIVED HERE AT ACR; ESPECIALLY THE CREW COM TRAINING (LOFT); MADE THIS EVENT SEEM MORE LIKE A SIMULATOR RIDE. WE DID HAVE SOME PROB GETTING THE CABIN ALT TO COME DOWN AND WENT TO MANUAL PRESSURIZATION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR ADVISED THAT NO DETAILS ON THE FAILED ENG ARE AVAILABLE FROM MAINT. THE RPTR STATED A VISUAL CHK OF THE ENG ON THE GND INDICATED NO EXTERNAL LEAKS AS THE ENG WAS DRY BUT THE TAILPIPE WAS NOT INSPECTED.
