On December 14, 2007, at 1555 central standard time, a Boeing 777-222, N220UA, operated by United Airlines as flight 836, sustained minor damage when smoke entered the cabin during approach for landing at O'Hare International Airport (ORD), Chicago, Illinois. The international air carrier flight was being conducted under 14 CFR Part 121 on an instrument flight rules flight plan. One passenger was seriously injured during the subsequent emergency evacuation. The remaining 248 passengers, 11 cabin crew members, and 4 flight crew members were not injured. The flight departed Pudong International Airport (PVG), Shanghai, China, about 0800 universal coordinated time. ORD was the intended destination.
The crew reported that smoke began to fill the passenger cabin, beginning from the rear of the airplane, about 10 miles from the airport. The concentration of the smoke increased and the captain subsequently declared an emergency. The flight landed on runway 10 and exited at taxiway M5. At that point the captain ordered an emergency evacuation.
The initial post accident inspection revealed a low oil quantity in the right engine. Metallic deposits were observed on one of the engine chip detectors. In addition, oil deposits were located in the compressor section of the engine. No evidence of an engine or cabin fire was observed.
