Narrative:
Throttles were advanced to takeoff position for takeoff. All engines responded normally. EPR on all engines reached takeoff values. At approximately 30-40 KTS #1 engine rolled rapidly back to idle causing aircraft to veer to left. Runway was damp and rubber- covered, exacerbating the problem. Takeoff was immediately aborted. No runway excursion occurred. Wind was less than 10 KTS at approximately 270 degrees, runway was 01. All engine indications were normal at idle. I elected to perform static engine runup, leaving passenger on board without maintenance personnel on board. Same was performed to takeoff power twice with no abnormal indications of any kind. I then elected to takeoff without maintenance inspection. Takeoff was normal in every respect. Flight continued to destination without further incident. Since my experience with this aircraft is limited and never having experienced a compressor stall in this type. I assumed roll back was caused by compressor stall, since subsequent engine runups were normal. With hindsight and applicable regulations in front of me, I find I should not have relied upon my experience, but should have removed passenger, made logbook entry, and had maintenance personnel on board during runup, allowing them to be final authority on engine performance.
Original NASA ASRS Text
Title: AFTER AN ABORTED TKOF, CAPT DEPARTED WITHOUT THE APPROPRIATE ACFT RELEASE FOR SVC.
Narrative: THROTTLES WERE ADVANCED TO TKOF POS FOR TKOF. ALL ENGS RESPONDED NORMALLY. EPR ON ALL ENGS REACHED TKOF VALUES. AT APPROX 30-40 KTS #1 ENG ROLLED RAPIDLY BACK TO IDLE CAUSING ACFT TO VEER TO L. RWY WAS DAMP AND RUBBER- COVERED, EXACERBATING THE PROBLEM. TKOF WAS IMMEDIATELY ABORTED. NO RWY EXCURSION OCCURRED. WIND WAS LESS THAN 10 KTS AT APPROX 270 DEGS, RWY WAS 01. ALL ENG INDICATIONS WERE NORMAL AT IDLE. I ELECTED TO PERFORM STATIC ENG RUNUP, LEAVING PAX ON BOARD WITHOUT MAINT PERSONNEL ON BOARD. SAME WAS PERFORMED TO TKOF PWR TWICE WITH NO ABNORMAL INDICATIONS OF ANY KIND. I THEN ELECTED TO TKOF WITHOUT MAINT INSPECTION. TKOF WAS NORMAL IN EVERY RESPECT. FLT CONTINUED TO DEST WITHOUT FURTHER INCIDENT. SINCE MY EXPERIENCE WITH THIS ACFT IS LIMITED AND NEVER HAVING EXPERIENCED A COMPRESSOR STALL IN THIS TYPE. I ASSUMED ROLL BACK WAS CAUSED BY COMPRESSOR STALL, SINCE SUBSEQUENT ENG RUNUPS WERE NORMAL. WITH HINDSIGHT AND APPLICABLE REGS IN FRONT OF ME, I FIND I SHOULD NOT HAVE RELIED UPON MY EXPERIENCE, BUT SHOULD HAVE REMOVED PAX, MADE LOGBOOK ENTRY, AND HAD MAINT PERSONNEL ON BOARD DURING RUNUP, ALLOWING THEM TO BE FINAL AUTHORITY ON ENG PERFORMANCE.
