ATA 7200

Part: ENGINE — FAULTED (LEFT) · airframe 7,100 hrs · 5,530 cycles

ON TAKEOFF, AIR CIRCULATION NOISES INCREASED AS ENGINE POWER WAS APPLIED. INTO THE TAKEOFF, THE ACM OVERHEAT LIGHT WAS NOT NOTED UNTIL AFTER V1, SO THE TAKEOFF WAS CONTINUED. AFTER ROTATION, THE ITT INDICATIONS ON THE LEFT ENGINE WENT COMPLETELY RED IN COLOR. POWER WAS REDUCED TO BRING THE ITT BACK TO A NORMAL RANGE, AND EXTINGUISH THE ACM OVERHEAT WARNING LIGHT. SMOKE BEGAN TO COME INTO THE CABIN, AND AN IMMEDIATE RETURN FOR LANDING WAS REQUESTED FROM THE TOWER. THE PLANE WAS LANDED BELOW THE MAXIMUM LANDING WEIGHT, SO THOSE PARAMETERS WERE NOT EXCEEDED. IT IS ESTIMATED THAT THE ITT WAS RED FOR 5-10 SECONDS, AND LIKELY CLOSER TO 5 SECONDS. WE TOOK OFF FROM RUNWAY 20, ENTERED A LEFT PATTERN TO LANDING ON RUNWAY 20. THE POSSIBILITY OF AN ENGINE BIRD STRIKE WAS CONSIDERED, BUT CANNOT BE CONFIRMED WITHOUT AN INSPECTION.
