LGT HAS ENG FAILURE ON SECOND SEGMENT CLB. DIVERSION TO ALTERNATE.

Narrative

LOST PWR IN L ENG AT 800 FT. FAILURE WAS EXPLOSIVE -- LOUD NOISE AND VIOLENT YAW TO L. NOSE ATTITUDE WAS ABOUT 22 DEGS NOSE UP; SPD V2 PLUS 15 (158 KTS). FO WAS FLYING. FIRST IMPRESSION WAS THAT OF A MIDAIR COLLISION. ENG OUT PROFILE WAS FOLLOWED; HOWEVER IT TOOK A MIN(?) TO STABILIZE THE SIT; SHUT DOWN THE ENG; DECLARE AN EMER; DIVERT TO LAX AND SHOOT THE ILS TO RWY 25L AND AT 1000 FT SIDESTEP TO RWY 25R. THERE WAS NO INDICATION OF ANY FIRE IN THE AIR; AND INSPECTION OF ENG ON THE GND REVEALED TOTAL FAILURE OF LAST 3 STAGES OF TURBINE BLADES. TOTAL FLT TIME WAS 13 MINS. THE ORANGE COUNTY ARPT HAS A BAD COMBINATION OF: SHORT RWY; HVY TFC -- GA AND ACR; NOISE ABATEMENT DEP PROFILE WHICH REQUIRES A VERY HIGH NOSE UP ATTITUDE DURING INITIAL CLBOUT WHICH LIMITS FORWARD VISIBILITY AND MAKES HANDLING A VERY SUDDEN ENG FAILURE MORE DIFFICULT. ALTHOUGH THE ACFT WAS RIGHT AT THE MAX ALLOWABLE WT (205728 LBS) FOR THIS ARPT; PERFORMANCE ON 1 ENG WAS EXCELLENT AND CTLABILITY WAS NO PROB. ATC WAS HELPFUL BUT DID NOT VOLUNTEER ANY EXTRA TIME OR SPECIAL HELP (VECTORS TO CORRECT BACK ON LOC AT LAX). OF COURSE I AM FULLY AWARE THAT WE COULD HAVE REQUESTED IT.
