AN ACR SF34 FLC EXPERIENCED COMPRESSOR STALLS ON THE L ENG DURING INITIAL CLBOUT. THEY TURNED OFF THE CONSTANT TORQUE ON TKOF SYS (AN AUTOPLT TYPE OF SYS) AND THE ENG RETURNED TO NORMAL OP.

Narrative

ON INITIAL CLB FROM LEX; BOTH THE CAPT AND FO NOTED MOMENTARY PWR FLUCTUATIONS OCCURRING ON THE L ENG ACCOMPANIED BY SLIGHT YAWING OF THE ACFT. THE FO; WHO WAS ALSO THE PNF; LATER CONFIRMED THAT THESE FLUCTUATIONS WERE NOTED ON THE L TORQUE GAUGE AND RANGED FROM APPROX 30-110% TORQUE IN RAPID SUCCESSION. EXACT READINGS WERE DIFFICULT TO OBTAIN DUE TO THE SPD OF OCCURRENCES (LESS THAN 2 SECONDS PER OCCURRENCE). NO OTHER ABNORMAL ENG PARAMETERS WERE NOTED AND THE TOTAL TIME OF THE EVENT WAS LESS THAN 10 SECONDS. WITH NO OTHER MALFUNCTION INDICATION OTHER THAN TORQUE FLUCTUATION; I CONCLUDED THESE WERE POSSIBLE COMPRESSOR STALLS AND ASKED THE FO TO BEGIN THE QRH PROCS FOR SUCH AN OCCURRENCE. AFTER THE CONSTANT TORQUE ON TKOF WAS TURNED OFF PER THE QRH; NORMAL ENG OP RESUMED. ALL ENG PARAMETERS RETURNED TO NORMAL AND REMAINED THERE UNDER CLOSE MONITOR FROM BOTH PLTS FOR THE DURATION OF THE FLT. WE COMPLETED THE PROC OUTLINED IN THE QRH UPON REACHING A SAFE ALT AND RESUMED NORMAL OP. AFTER DISCUSSION OF THE EVENTS WITH THE FO; I MADE NOTES TO INCLUDE IN MY WRITE-UP TO MAINT CTL. ON XFERRING THESE NOTES TO THE SHIP'S MMI LOGBOOK; I INCORRECTLY NOTED THAT THE TORQUE HAD FLUCTUATED FROM '30-120%' WHEN IN FACT THE ACTUAL VALUES WERE APPROX 30- 110%. IN HINDSIGHT; I SHOULD HAVE HAD THE FO REVIEW THE WRITE-UP BEFORE FORWARDING TO MAINT CTL. THE ENG NEVER EXCEEDED LIMITATIONS AND REMAINED STABLE AFTER THE OCCURRENCE. WE PROCEEDED TO DTW AND LANDED WITHOUT INCIDENT.
