## Discrepancy

DURING A TEST OF THE ANTI-ICE SYSTEM AT 39,000 FT,  A VERY STRONG ODOR OF SMOKE AND BURNED POPCORN FILLED THE CABIN.  WING HEAT REACHED MIDDLE GREEN, STAB HEAT BARELY ENTERED THE GREEN.  TESTED EACH NAC HT INDIVIDUALLY NO ODOR,  ODOR CAME BACK STRONGLY. AIRCRAFT AND THE CREW LANDED SAFELY TO BASE WITH NO OTHER INCIDENTS.
