## Discrepancy

SHORTLY AFTER TAKEOFF AN ODOR OF SMOKE APPEARED IN THE CABIN. ONE OF THE PASSENGERS ADVISED THAT THE FORWARD ENTRY LIGHT AT THE TOP OF THE STAIRS WAS ARCING. UPON LANDING WE FOUND THAT THE PLASTIC LENS WAS MELTED.  FOUND FWD ENTRY LIGHT HAD CHAFED WIRE ARCING AGAINST MOUNTING SCREW. R & R LIGHT ASSEMBLY IAW MM 33-20-04.  OPS CHECKED GOOD.
