## Discrepancy

JUST PRIOR TO ROTATION WE EXPERIENCED ACRID SMELL IN COCKPIT WHICH CLEARED PROMPTLY AFTER TO SMELL DISSIPATED WITHIN 20 TO 30 SECONDS NO SMELL IN CABIN. NOTE MAX EPR TAKE-OFF INSPECTED ENG INLETS DUE FULL POWER T/O AND NO ABNORMALITIES FOUND. ALSO CHECKED ALL ELECTRICAL PANELS IN MEC (P31,32,33,34,37,5 0,51,54) FOR EVIDENCE OF OVERHEATING OR ACRID SMELL, FOUND ALL NORMAL. NO PREVIOUS HISTORY OF THIS PROBLEM.
