What needs to be clarified
The task could be to examine which technical circumstances the available data support and which remain hypotheses.
Materials to prepare
- Original system and controller logs with a description of how files were obtained.
- Component documents, version details and configuration change records.
- Repair history, condition photographs and a description of the event.
What to compare
- Whether logs relate to the specific device and period.
- Consistency of times, versions and message sequence.
- Effect of data gaps on checking the proposed cause.
Possible outcome of the analysis
A possible output is a reconciled chronology of records, an account of discrepancies and a list of additional data for testing technical hypotheses.
Limits of the conclusions
Incomplete logs may prevent identification of the failure cause; the analysis does not imply an unapproved flight, establish airworthiness or replace authorisation or certification procedures.
