Remaining life and continued operation

Is a lifetime extension technically defensible?

A lifetime-extension assessment brings together original design information, operating history, inspections, modifications and updated analyses to determine whether continued service can be justified.

A lifetime-extension assessment brings together original design information, operating history, inspections, modifications and updated analyses to determine whether continued service can be justified.

A life extension is an evidence-based engineering argument.

A single recalculated fatigue number is rarely sufficient. The assessment should show how design assumptions compare with actual service and how inspections confirm or challenge the predicted damage mechanisms.

AeroMech structures the available evidence, identifies gaps and performs targeted analyses. The conclusion can include inspection requirements, operating restrictions or monitoring actions where these are necessary to support continued service.

Typical engineering questions

Questions this assessment can answer.

The analysis is organised around the decision, not around a software package.

What has changed since the original design assessment?
Are actual loads lower or higher than the original assumptions?
What fatigue life has already been consumed?
Do inspections support the analytical assumptions?
Which locations require additional inspection or monitoring?
Can continued operation be supported with conditions or limitations?
Assessment scope

From structural behaviour to a defensible conclusion.

Evidence review

Original calculations, drawings, load cases, operating records, inspections and repairs.

Updated assessment

Recalculation using current geometry, loading, material data and observed condition.

Decision support
