Aircraft Reliability – Component Removal

Reliability monitoring of aircraft is a vital topic for consideration both as part of aircraft management (CAMO) and also aircraft leasing as a repeating defect can be grounds for a financial arrangement if the defect repeats within a certain time frame.

When we mention component removals for reliability purposes, we are not concerned about planned routine component removals. For example, if we remove a component for a reason such as an overhaul or to perform a modification then this is a planned removal. It does not have a negative impact on the aircraft and or component as it has not actually failed in service.

We need to analyse however any component that is removed because of a failure, a defect or indeed a suspected failure/defect.A component that fails a check such as an operational of the functional check, as part of a system or individually we need to analyse –this failure is not scheduled, and we did not expect the component to fail.

Apart removed during a scheduled task is not removed “Un Scheduled” but rather removed as “Scheduled” –depending on the MIS (Maintenance Information System) this can be hard to determine, and users often remove parts that are scheduled as unscheduled making metrics harder to capture accurately.
