Narrative:

On takeoff from runway 4R iln at approximately V1, felt plane dip left (not a yaw) then noticed vibration and noise. Scanned engine instruments, saw #1 engine EPR at 1.3 - 1.2 temperature in yellow. Because of timing of occurrence, I treated it as a blown tire which damaged left engine. Kept gear down as long as I could climb/maintain altitude. If engine quit then would raise gear and deal with any subsequent problems that might cause. Declared emergency, returned to airport. Set up for single engine approach in case #1 engine quit on final approach. Made smooth touchdown.

Title: A DC9 LOSES A TIRE ON TKOF. THE CREW ELECTS TO LEAVE THE GEAR DOWN, USE PARTIAL PWR ON A DAMAGED L ENG AND RETURN LAND AT ILN, OH.

Narrative: ON TKOF FROM RWY 4R ILN AT APPROX V1, FELT PLANE DIP L (NOT A YAW) THEN NOTICED VIBRATION AND NOISE. SCANNED ENG INSTS, SAW #1 ENG EPR AT 1.3 - 1.2 TEMP IN YELLOW. BECAUSE OF TIMING OF OCCURRENCE, I TREATED IT AS A BLOWN TIRE WHICH DAMAGED L ENG. KEPT GEAR DOWN AS LONG AS I COULD CLB/MAINTAIN ALT. IF ENG QUIT THEN WOULD RAISE GEAR AND DEAL WITH ANY SUBSEQUENT PROBS THAT MIGHT CAUSE. DECLARED EMER, RETURNED TO ARPT. SET UP FOR SINGLE ENG APCH IN CASE #1 ENG QUIT ON FINAL APCH. MADE SMOOTH TOUCHDOWN.
