A fault model in an aerospace context is a set of structured information which helps users or systems to identify and isolate a problem that occurs on an engine, line-replaceable unit (LRU), or auxiliary power unit (APU) during a flight. Associated with this fault model may be a suggested repair procedure along with references to aircraft ...
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
graph with an example of steps in a failure mode and effects analysis. Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects.
Failure mode effects and criticality analysis (FMECA) is an extension of failure mode and effects analysis (FMEA).. FMEA is a bottom-up, inductive analytical method which may be performed at either the functional or piece-part level.
The impact of any latent fault tests, and The operational profile (environmental stress factors). Given a component database calibrated with field failure data that is reasonably accurate, [ 1 ] the method can predict device level failure rate per failure mode, useful life, automatic diagnostic effectiveness, and latent fault test effectiveness ...
The National Transportation Safety Board has more concerns about Boeing's planes. It said at least 40 airlines outside the US may be operating aircraft with risky rudder parts.
