The aircraft almost rolled but after putting all the power to the No. 3 engine, the wing was brought back up (Gonzales, 2017). Basically, thrust from engine No. 1 and No. 3 helped control the aircraft. It was also helpful that a DC-10 check pilot happened to be on board (FAA, n.d.). From the readings, the crew did everything possible to salvage the aircraft. The issues resulted from poor maintenance practices. It appears that there was a fatigue crack in the fan rotor disk that resulted from a metallurgical defect (NTSB, 1990). The issue appeared to begin when the part was being manufactured. The flaw was not visible to the naked eye and went undetected. It was noted in the accident report that the flaw could have been detected if the part had been macroetch inspected (NTSB, 1990).

If the location of the three hydraulic systems could not have been changed, it would have been useful to have some sort of emergency backup system to prevent the total loss of control (FAA, n.d.).
