Evidence stage
ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
Signing off and return to service
Approving the work and the aircraft for return to service, and signing the maintenance record that says so.
Still human-led✓ Evidence-backed
Where this applies
United States, certificated repair stations. The rule says that, except for individuals employed by a repair station located outside the United States, only an employee appropriately certificated as a mechanic or repairman under part 65 is authorized to sign off on final inspections and maintenance releases for the repair station. It reserves the final sign-off for certificated people; it says nothing about inspection tools.
What this means
In maintenance organisations as well as airlines, the final release is reserved for certificated people. That is the part of this job the rules keep scarce.
What it does not yet show
A US rule for repair stations; it does not measure staffing or how inspections are done.
What you can check
Open 14 CFR 145.213 on eCFR and find "is authorized to sign off on final inspections and maintenance releases".
Does it change the assessment?
No. The impact index is never moved by a single event. Nor did this record change a layer: all 1 linked judgement above already rested on earlier evidence. This one adds to them.
