Narrative:
Upon reaching FL360 for FL370 hkg control cleared us direct to kadio (an unfamiliar intersection not on our flight plan) and to contact taipei control. I put the B autoplt to command (from off) and noted the throttles retard and assumed we had an altitude capture. I diverted my attention to look for kadio on the chart. Next I knew we were approaching FL380 at 1000 FPM. In an effort to level off, I pulled power too rapidly resulting in a compressor stall on #1 (resultant overtemp and shutdown). Things happened pretty fast but I suspect that I had put the autoplt in command and then failed to reconnect the pms, thus the reason for no altitude capture. Contributing factor: ATC hong kong cleared us from an off airway position to kadlo (not on our flight plan) at a critical time just prior to level off. Supplemental information from acn 193942: he pulled power back rather fast and #1 engine compressor stalled and overtemped. Engine was shut down. Clearance was requested to descend to 350 and air start was accomplished. Main problem was failure of the autoplt to capture altitude on pms as it should have. Contributing factors were capts (my) failure to monitor vertical flight path due to distraction caused by ATC clearance to an intersection not on flight plan and a rather involved company procedure for entering data in INS and checking it. At the same time I was entering data on flight plan form and preparing the airep (position report). Believe ATC should make an effort to not clear aircraft to points not on their flight plan unless requested, or necessary, and if so, preferably not at critical phases of flight.

Title: ACR WDB ALTDEV OVERSHOT DURING CLB THEN CAUSED A COMPRESSOR STALL AND INFLT ENG SHUTDOWN WITH RAPID THRUST LEVER MOVEMENT.
Narrative: UPON REACHING FL360 FOR FL370 HKG CTL CLRED US DIRECT TO KADIO (AN UNFAMILIAR INTXN NOT ON OUR FLT PLAN) AND TO CONTACT TAIPEI CTL. I PUT THE B AUTOPLT TO COMMAND (FROM OFF) AND NOTED THE THROTTLES RETARD AND ASSUMED WE HAD AN ALT CAPTURE. I DIVERTED MY ATTN TO LOOK FOR KADIO ON THE CHART. NEXT I KNEW WE WERE APCHING FL380 AT 1000 FPM. IN AN EFFORT TO LEVEL OFF, I PULLED PWR TOO RAPIDLY RESULTING IN A COMPRESSOR STALL ON #1 (RESULTANT OVERTEMP AND SHUTDOWN). THINGS HAPPENED PRETTY FAST BUT I SUSPECT THAT I HAD PUT THE AUTOPLT IN COMMAND AND THEN FAILED TO RECONNECT THE PMS, THUS THE REASON FOR NO ALT CAPTURE. CONTRIBUTING FACTOR: ATC HONG KONG CLRED US FROM AN OFF AIRWAY POS TO KADLO (NOT ON OUR FLT PLAN) AT A CRITICAL TIME JUST PRIOR TO LEVEL OFF. SUPPLEMENTAL INFO FROM ACN 193942: HE PULLED PWR BACK RATHER FAST AND #1 ENG COMPRESSOR STALLED AND OVERTEMPED. ENG WAS SHUT DOWN. CLRNC WAS REQUESTED TO DSND TO 350 AND AIR START WAS ACCOMPLISHED. MAIN PROBLEM WAS FAILURE OF THE AUTOPLT TO CAPTURE ALT ON PMS AS IT SHOULD HAVE. CONTRIBUTING FACTORS WERE CAPTS (MY) FAILURE TO MONITOR VERT FLT PATH DUE TO DISTR CAUSED BY ATC CLRNC TO AN INTXN NOT ON FLT PLAN AND A RATHER INVOLVED COMPANY PROC FOR ENTERING DATA IN INS AND CHKING IT. AT THE SAME TIME I WAS ENTERING DATA ON FLT PLAN FORM AND PREPARING THE AIREP (POS RPT). BELIEVE ATC SHOULD MAKE AN EFFORT TO NOT CLR ACFT TO POINTS NOT ON THEIR FLT PLAN UNLESS REQUESTED, OR NECESSARY, AND IF SO, PREFERABLY NOT AT CRITICAL PHASES OF FLT.
