An invisible crack in a titanium disc, a supposedly unbreakable plane component, threatens a flight. What would you do when the impossible happens?
The invisible crack that exploded a plane
This episode recounts the harrowing experience of United Airlines Flight 232, when a catastrophic engine failure disabled all hydraulic systems. It explores the extraordinary decisions made by the flight crew in a situation for which no procedure existed.
Event: United Airlines Flight 232
Date: July 19, 1989
Aircraft: McDonnell Douglas DC-10
Engine: General Electric CF6
Location: Over the American Midwest
- A farmer in Iowa discovered a large titanium disc, part of a General Electric engine, three months after the incident.
- The DC-10, delivered in 1971, had logged over 43,000 flight hours and 16,000 takeoff-and-landing cycles.
- The engine's stage-one fan disc contained a microscopic crack, invisible to standard inspection methods, that had grown since its forging.
- Investigators found two forgings with identical serial numbers and conflicting paper trails, making it impossible to definitively identify the origin of the failed disc.
- Captain Al Haynes, First Officer Bill Records, Flight Engineer Dudley Dvorak, and off-duty check pilot Denny Fitch faced a complete loss of flight controls.
