Narrative:

Climbing through 18000' on V552, 10 NM from PCU VOR, we heard and felt a loud bank coming from the left side of the aircraft. The first officer was flying the aircraft at the time of the vent. I glanced at the engine INS and determined that the #1 engine INS (EPR, N1, N2, etc) were unwinding. I took control of the aircraft and brought the #1 throttle to idle and the first officer turned off the autothrottles. The first officer then proceeded to the emergency checklist and we shut down the #1 engine. I then requested form ATC to level off at 18000' and informed the controller of our engine problem. He asked if we needed any assistance and I told him to stand by. At this time, I instructed the a-line F/a to inform the passenger in an unalarming manner that we had engine problems and the aircraft was flying fine, and we were diverting to msy. I then told my first officer to ask for vectors to msy from ATC. The first officer then completed all the required checklists for the emergency and the normal checklists for the approach into msy. We then discussed runway options at msy and I selected runway 28 due to the length and minimal crosswind. I also requested men and equipment to stand by as a precautionary measure. The approach and landing were uneventful. We taxied to the gate and deplaned the passenger.

Narrative: CLBING THROUGH 18000' ON V552, 10 NM FROM PCU VOR, WE HEARD AND FELT A LOUD BANK COMING FROM THE LEFT SIDE OF THE ACFT. THE F/O WAS FLYING THE ACFT AT THE TIME OF THE VENT. I GLANCED AT THE ENG INS AND DETERMINED THAT THE #1 ENG INS (EPR, N1, N2, ETC) WERE UNWINDING. I TOOK CTL OF THE ACFT AND BROUGHT THE #1 THROTTLE TO IDLE AND THE F/O TURNED OFF THE AUTOTHROTTLES. THE F/O THEN PROCEEDED TO THE EMER CHKLIST AND WE SHUT DOWN THE #1 ENG. I THEN REQUESTED FORM ATC TO LEVEL OFF AT 18000' AND INFORMED THE CTLR OF OUR ENG PROB. HE ASKED IF WE NEEDED ANY ASSISTANCE AND I TOLD HIM TO STAND BY. AT THIS TIME, I INSTRUCTED THE A-LINE F/A TO INFORM THE PAX IN AN UNALARMING MANNER THAT WE HAD ENG PROBS AND THE ACFT WAS FLYING FINE, AND WE WERE DIVERTING TO MSY. I THEN TOLD MY F/O TO ASK FOR VECTORS TO MSY FROM ATC. THE F/O THEN COMPLETED ALL THE REQUIRED CHKLISTS FOR THE EMER AND THE NORMAL CHKLISTS FOR THE APCH INTO MSY. WE THEN DISCUSSED RWY OPTIONS AT MSY AND I SELECTED RWY 28 DUE TO THE LENGTH AND MINIMAL XWIND. I ALSO REQUESTED MEN AND EQUIP TO STAND BY AS A PRECAUTIONARY MEASURE. THE APCH AND LNDG WERE UNEVENTFUL. WE TAXIED TO THE GATE AND DEPLANED THE PAX.
