Contained and Uncontained Failures
Two terms are helpful in describing the nature of engine failures. A “contained” engine failure is one in which components might separate inside the engine but either remain within the engine’s cases or exit the engine through the tail pipe. This is a design feature of all engines and generally should not pose an immediate flight risk. An “uncontained” engine failure can be more serious because pieces from the engine exit the engine at high speeds in other directions, posing potential danger to the aircraft structure and persons within the plane. In the United States, the National Transportation Safety Board will likely investigate any uncontained engine failure involving a transport category aircraft.

Famous quotes containing the words contained and, contained and/or failures:
“Yet there is a mystery here and it is not one that I understand: without the sting of otherness, of—even—the vicious, without the terrible energies of the underside of health, sanity, sense, then nothing works or can work. I tell you that goodness-what we in our ordinary daylight selves call goodness: the ordinary, the decent—these are nothing without the hidden powers that pour forth continually from their shadow sides. Their hidden aspects contained and tempered.”
—Doris Lessing (b. 1919)
“Like desire, language disrupts, refuses to be contained within boundaries.”
—bell hooks (b. c. 1955)
“Our children will not survive our habits of thinking, our failures of the spirit, our wreck of the universe into which we bring new life as blithely as we do. Mostly, our children will resemble our own misery and spite and anger, because we give them no choice about it. In the name of motherhood and fatherhood and education and good manners, we threaten and suffocate and bind and ensnare and bribe and trick children into wholesale emulation of our ways.”
—June Jordan (b. 1939)
