Narrative:
We had a compressor stall on #2 engine during application of takeoff power. The engine had pwred up just enough to arm the autopack trip system. When the stall occurred, the engine rolled back just enough to trip the system. We aborted at no more than 60 KTS. We taxied clear, complied with checklists, and then discussed whether we needed to write it up in the logbook. After discussing the impact of the 30 degree, 11 KT crosswind, we decided it was the standard B727 #2 crosswind compressor stall and we would press on. The correct answer would have been to write it up and return to the gate. Because it is such a well known phenomenon, I think we have become conditioned to accept this as normal.

Title: A B727 ON TKOF ROLL REJECTED THE TKOF AT 60 KTS DUE TO XWIND #2 ENG STALL. CREW COMPLIED WITH CHKLISTS AND PROCEEDED WITH TKOF WITH NO LOG ENTRY.
Narrative: WE HAD A COMPRESSOR STALL ON #2 ENG DURING APPLICATION OF TKOF PWR. THE ENG HAD PWRED UP JUST ENOUGH TO ARM THE AUTOPACK TRIP SYS. WHEN THE STALL OCCURRED, THE ENG ROLLED BACK JUST ENOUGH TO TRIP THE SYS. WE ABORTED AT NO MORE THAN 60 KTS. WE TAXIED CLR, COMPLIED WITH CHKLISTS, AND THEN DISCUSSED WHETHER WE NEEDED TO WRITE IT UP IN THE LOGBOOK. AFTER DISCUSSING THE IMPACT OF THE 30 DEG, 11 KT XWIND, WE DECIDED IT WAS THE STANDARD B727 #2 XWIND COMPRESSOR STALL AND WE WOULD PRESS ON. THE CORRECT ANSWER WOULD HAVE BEEN TO WRITE IT UP AND RETURN TO THE GATE. BECAUSE IT IS SUCH A WELL KNOWN PHENOMENON, I THINK WE HAVE BECOME CONDITIONED TO ACCEPT THIS AS NORMAL.
