During flight and on the ground, fumes entered the cabin, and cabin crew, as well as passenger, complained of feeling ill. Flight attendants and pilots were tested at a hospital and levels of carbon monoxide were detected in their system. Fumes were attributed to leaking hydraulic fluid from thrust reversers contaminating APU and air conditioning system.

Narrative:

Carbon monoxide poisoning during flight and probably on the ground working with the mechanics trying to find the source of the fumesecond officerdor detected during approach and on the ground. After deplaning the passenger the flight attendants reported feeling ill and an electrical/hot plastic smell in the cabin of the MD80. Maintenance was advised but could not find any source. After airing the cabin we started reboarding the passenger. Boarding was suspended when the odor reappeared. All passenger were off-loaded. The flight attendants later went to the hospital and were tested. They had carbon monoxide levels of trace, 0.4 and 1.2. Later that evening the first officer and I were tested for carbon monoxide and had levels of .5 and .6. Later that evening we were released for flight. The flight attendants remained in las for several days before returning home. Several hydraulic leaks were discovered in the left engine thrust reversers and in the tail cone. APU was contaminated with hydraulic fluid as well as the air conditioning system.

Original NASA ASRS Text

Title: DURING FLT AND ON THE GND, FUMES ENTERED THE CABIN, AND CABIN CREW, AS WELL AS PAX, COMPLAINED OF FEELING ILL. FLT ATTENDANTS AND PLTS WERE TESTED AT A HOSPITAL AND LEVELS OF CARBON MONOXIDE WERE DETECTED IN THEIR SYS. FUMES WERE ATTRIBUTED TO LEAKING HYD FLUID FROM THRUST REVERSERS CONTAMINATING APU AND AIR CONDITIONING SYS.

Narrative: CARBON MONOXIDE POISONING DURING FLT AND PROBABLY ON THE GND WORKING WITH THE MECHS TRYING TO FIND THE SOURCE OF THE FUMES/ODOR DETECTED DURING APCH AND ON THE GND. AFTER DEPLANING THE PAX THE FLT ATTENDANTS RPTED FEELING ILL AND AN ELECTRICAL/HOT PLASTIC SMELL IN THE CABIN OF THE MD80. MAINT WAS ADVISED BUT COULD NOT FIND ANY SOURCE. AFTER AIRING THE CABIN WE STARTED REBOARDING THE PAX. BOARDING WAS SUSPENDED WHEN THE ODOR REAPPEARED. ALL PAX WERE OFF-LOADED. THE FLT ATTENDANTS LATER WENT TO THE HOSPITAL AND WERE TESTED. THEY HAD CARBON MONOXIDE LEVELS OF TRACE, 0.4 AND 1.2. LATER THAT EVENING THE FO AND I WERE TESTED FOR CARBON MONOXIDE AND HAD LEVELS OF .5 AND .6. LATER THAT EVENING WE WERE RELEASED FOR FLT. THE FLT ATTENDANTS REMAINED IN LAS FOR SEVERAL DAYS BEFORE RETURNING HOME. SEVERAL HYD LEAKS WERE DISCOVERED IN THE L ENG THRUST REVERSERS AND IN THE TAIL CONE. APU WAS CONTAMINATED WITH HYD FLUID AS WELL AS THE AIR CONDITIONING SYS.
