United Airlines Flight 232: DC-10 Loses All Hydraulic Control Systems and Crash Landed ✈️ #shorts

𝗨𝗻𝗶𝘁𝗲𝗱 𝗔𝗶𝗿𝗹𝗶𝗻𝗲𝘀 𝗙𝗹𝗶𝗴𝗵𝘁 𝟮𝟯𝟮 was a scheduled domestic passenger flight from Denver to Philadelphia with an intermediate stop in Chicago. The flight was being operated by a McDonnell Douglas DC-10 (Reg. N1819U) on 𝗝𝘂𝗹𝘆 𝟭𝟵, 𝟭𝟵𝟴𝟵.

The plane departed Denver at 14:09 CDT and climbed to its cruising altitude of 37,000 feet. About 1 hour and 7 minutes after takeoff, at 15:16, the flightcrew heard a loud bang or an explosion. After checking the engine instruments, the flightcrew determined that the No. 2 engine had failed. While performing the engine shutdown checklist, the flight engineer observed that the plane's normal systems hydraulic pressure and quantity gauges indicated zero. At 15:20, the flightcrew radioed the Minneapolis ARTCC and requested emergency assistance and vectors to the nearest airport.

At 15:22, the controller informed the flightcrew that they were proceeding in the direction of Sioux City and later gave vectors to the Sioux Gateway Airport. A UAL DC-10 training check airman, who was off duty and seated in a first class seat, volunteered his assistance and was invited to the cockpit at about 15:29. In the last 20 seconds before touchdown, the airspeed averaged 215 KIAS, and the sink rate was 1,620 ft/min. The plane touched down on the threshold slightly to the left of the centerline on runway 22 at 16:00. The plane skidded to the right of the runway and rolled inverted. The accident resulted in 111 fatal, 47 serious, and 125 minor injuries. The remaining 13 occupants were not injured.

𝗣𝗿𝗼𝗯𝗮𝗯𝗹𝗲 𝗖𝗮𝘂𝘀𝗲:
"The National Transportation Safety Board determines that the probable cause of this accident was the inadequate consideration given to human factors limitations in the inspection and quality control procedures used by United Airlines' engine overhaul facility which resulted in the failure to detect a fatigue crack originating from a previously undetected metallurgical defect located in a critical area of the stage 1 fan disk that was manufactured by General Electric Aircraft Engines. The subsequent catastrophic disintegration of the disk resulted in the liberation of debris in a pattern of distribution and with energy levels that exceeded the level of protection provided by design features of the hydraulic systems that operate the DC-10's flight controls."
