## Discrepancy

ODOR AFTER APU BLEED WAS TURNED ON,  CONTINUED AND GOT WORSE AFTER TAKEOFF. FINALLY DISSIPATED. INFORMED BY CREW, CABIN DEVELOPED STRONG HEATER TYPE ODOR ON TAKEOFF, TINGED WITH A VINEGAR, MUSTY OILY ODOR. EYES AND THROATS AFFECTED. ODOR DISSIPATED AT CRUISE. UPON START OF DESCENT, ODOR RETURNED FULL STRENGTH SAME AS TAKEOFF. PERFORMED WORK CARD 05-96-84 AND 05-96-85. UNABLE TO DETERMINE SOURCE OF ODOR DUE TO LACK OF INFORMATION FROM LAST FLIGHT CREW.
