Narrative:

On takeoff on runway 32R at ord, immediately upon landing gear retraction, the left engine began to have a compressor stall. A sequence of 6 or 7 rapid and loud bangs were heard and flames shot out the front of the engine. An immediate thrust loss on left engine was noticed. Engine failure on takeoff procedures were initiated, the plane was cleaned up, we declared an emergency, and we flew towards lake michigan climbing to 4000 ft to dump fuel to get to our maximum landing weight. The engine had attained a temperature of 784 degrees C and was at 632 degrees C in idle -- both above maximum. The engine was shut down and no restart attempted. An uneventful single engine approach and landing was flown to runway 27L at ord.

Title: B767 HAS COMPRESSOR STALL AT GEAR RETRACTION. DUMPS FUEL. RETURNS TO UNEVENTFUL LNDG.

Narrative: ON TKOF ON RWY 32R AT ORD, IMMEDIATELY UPON LNDG GEAR RETRACTION, THE L ENG BEGAN TO HAVE A COMPRESSOR STALL. A SEQUENCE OF 6 OR 7 RAPID AND LOUD BANGS WERE HEARD AND FLAMES SHOT OUT THE FRONT OF THE ENG. AN IMMEDIATE THRUST LOSS ON L ENG WAS NOTICED. ENG FAILURE ON TKOF PROCS WERE INITIATED, THE PLANE WAS CLEANED UP, WE DECLARED AN EMER, AND WE FLEW TOWARDS LAKE MICHIGAN CLBING TO 4000 FT TO DUMP FUEL TO GET TO OUR MAX LNDG WT. THE ENG HAD ATTAINED A TEMP OF 784 DEGS C AND WAS AT 632 DEGS C IN IDLE -- BOTH ABOVE MAX. THE ENG WAS SHUT DOWN AND NO RESTART ATTEMPTED. AN UNEVENTFUL SINGLE ENG APCH AND LNDG WAS FLOWN TO RWY 27L AT ORD.
