Lifing Identification

Where an asset exhibits failure characteristics based on its usage, then a mechanism is required to be able to identify which parameter of the asset’s operation its life is to be based on, e.g. calendar time, distance driven, hours flown. If the asset is a sub-component of a parent asset whose usage is recorded using a different parameter to its constituent part(s), the facility should be provided to record the parent’s usage, then an appropriate conversion factor applied to update the constituent part’s life usage. Similarly, if the component consumes life at a faster rate than its parent, an exchange rate should be applied. Where necessary, multiple lifing parameters need to be catered for, e.g. 9000 miles or 6 months, which ever occurs first.

As the asset or its parent is operated, the appropriate lifing parameters must be captured at regular intervals to ensure that any maintenance activities related to life usage can be anticipated and planned.

In support of the RAF’s fast jet engines, and tri-service use of Ground Support Equipment used to support all aircraft operations, LSC Group has developed software applications which include the ability to monitor life usage based on multiple parameters. In support of this development activity, LSC Group personnel have a deep understanding of the business processes employed in defining and monitoring of component life.
