• fault: state of an item characterized by inability to perform a required function, excluding the inability during preventive maintenance or other planned actions, or due to lack of external resources
(Source: IEV 191-05-01)
• undetected fault: fault which is not detected by a diagnostic check
• design fault: fault in the design caused by a mistake in the design phase of a system. A design fault causes an error, remaining undetected in a part of the system until specific conditions affecting that part of the system are such that the produced result does not conform to the intended function. This results in a failure of that part of the system. If the conditions appear again, the same results will be produced
• error: discrepancy between a computed, observed or measured value or condition and the true, specified or theoretically correct value or condition
(Source: IEV 191-05-24)
• failure: termination of an item to perform a required function
(Source: IEV 191-04-01)
• mistake/human error: human action that produces an unintended result
(Source: IEV 191-05-25)
• failed state: condition of a component, equipment or system during the time when it is subject to a failure“
