Albert RiosMissed Class16 NOV 11United Airlines Flight 232On 19 July 1989, at 1516 local time, United Airlines Flight 232 crash landed in Sioux City, Iowa. The flight was a regular scheduled flight that resulted in a crash due to the catastrophic failure of the second engine. Although the casualties were great, the amount of survivors was much greater. The cause to the engine failure was determined as an inadequate consideration of limitations in human factors in the engines overhaul. Although there were 111 deaths, the accident has been considered a good example of crew resource management in the manner they preceded in dealing with the emergency. United Airlines Flight 232 was a regular scheduled flight from Stapleton International Airport in Denver, Colorado to OHare International Airport (KORD) in Chicago, Illinois. The flights final destination was set to be at Philadelphia International Airport (KPHL) in Philadelphia, Pennsylvania, using OHare international as a stopover. The aircraft flown was a McDonnell Douglas DC-10-10, which had a maximum of 399 passengers, 285 on this particular flight, and a crew of 11. Of the 296 total people on board, 185 survived. The accident occurred at Sioux Gateway Airport (KSUX) in Sioux City, Iowa. The cause of the crash landing was the flight crews decision in dealing with an in-flight emergency, the failure of the hydraulic operated controls. The use of the hydraulic powered controls was lost due to the stage 1 fan disk in the second, tail mounted GEAE engine, rupturing. The breaking of the stage 1 fan disk sprayed shrapnel into and through the hydraulic system, severing many of the lines. The fan disk ruptured because of a stress fracture that went undetected during the engine overhaul. The National Transportation Safety Board (NTSB) has determined that the likely cause was inadequate consideration given to human factors limitations in the inspection and quality control procedures used by United Airlines' engine overhaul facility. Many people died in this accident, despite this the accident has been deliberated an example of successful crew resource management. The plan had a large amount of survivors for this type of accident, and crash landing without conventional control. The crew quickly assessed the situation by first recognizing the problem and finding the solution that would cost the least amount of lives and damage. This happened to be an emergency landing in KSUX. The crew acted quickly to get down and get the plane on the ground before any more damage could be done. This was all done cohesively by the flight crew and as a result the pilots were deemed certain recognition for their actions. The captain later served as an instructor in CRM. This was a proper use of crew resource management.
