The flight crew of an air carrier B727 report of a loud compressor stall accompanied with an air conditioning pack trip and an engine fail light during takeoff. The flight crew performed a low speed reject and determined that the compressor stall was caused by the crosswind that had doubled as the takeoff roll was started.

Narrative:
On takeoff roll with engines stabilized for takeoff at a speed of about 30-40 KTS, we had a loud bang (compressor stall) with an automatic pack trip and engine fail lights momentarily. I rejected the takeoff to analyze the situation and taxied clear of the runway. We determined that the wind was a likely explanation (crosswind of 15-20 KTS). Maintenance recommended another attempt. We took off the second time using the compressor stall technique of not spooling the #2 engine to full power until above 60 KTS and had no problems. The wind had been only about 10 KTS crosswind when we taxied out, but increased to almost double just before the takeoff, so we didn't think there would be a compressor stall situation on the first try. It was also very unusual to have the automatic pack trip and engine failure light with the stall. Normally that doesn't happen.

Title: THE FLC OF AN ACR B727 RPT OF A LOUD COMPRESSOR STALL ACCOMPANIED WITH AN AIR CONDITIONING PACK TRIP AND AN ENG FAIL LIGHT DURING TKOF. THE FLC PERFORMED A LOW SPD REJECT AND DETERMINED THAT THE COMPRESSOR STALL WAS CAUSED BY THE XWIND THAT HAD DOUBLED AS THE TKOF ROLL WAS STARTED.
Narrative: ON TKOF ROLL WITH ENGS STABILIZED FOR TKOF AT A SPD OF ABOUT 30-40 KTS, WE HAD A LOUD BANG (COMPRESSOR STALL) WITH AN AUTO PACK TRIP AND ENG FAIL LIGHTS MOMENTARILY. I REJECTED THE TKOF TO ANALYZE THE SIT AND TAXIED CLR OF THE RWY. WE DETERMINED THAT THE WIND WAS A LIKELY EXPLANATION (XWIND OF 15-20 KTS). MAINT RECOMMENDED ANOTHER ATTEMPT. WE TOOK OFF THE SECOND TIME USING THE COMPRESSOR STALL TECHNIQUE OF NOT SPOOLING THE #2 ENG TO FULL PWR UNTIL ABOVE 60 KTS AND HAD NO PROBS. THE WIND HAD BEEN ONLY ABOUT 10 KTS XWIND WHEN WE TAXIED OUT, BUT INCREASED TO ALMOST DOUBLE JUST BEFORE THE TKOF, SO WE DIDN'T THINK THERE WOULD BE A COMPRESSOR STALL SIT ON THE FIRST TRY. IT WAS ALSO VERY UNUSUAL TO HAVE THE AUTO PACK TRIP AND ENG FAILURE LIGHT WITH THE STALL. NORMALLY THAT DOESN'T HAPPEN.
