Parts, stock and batch traceability
How FlyerOS holds parts stock with batch-level traceability, Form 1 and 8130-3 certification and shelf life, issued oldest-expiry-first with an override and a reason.
Last reviewed
Parts stock in FlyerOS is held so that what you fitted to an aircraft can always be traced back to where it came from. That traceability is the point, not a nicety.
Batch-level traceability
Stock is held in batches. A batch carries its certification, a Form 1 or an 8130-3, and its shelf life where it has one. When a part is issued to a work order, it is issued from a specific batch, so the certification and origin of the exact part fitted is recorded against the job.
Issued oldest-expiry-first
By default a part is issued from the batch with the nearest expiry first, so shelf-life stock is used before it lapses rather than left at the back of the shelf. If you need to issue from a different batch, you can, but it takes an override and a reason, which is recorded.
Out-of-date stock is not silent
Issuing a part whose batch is out of shelf life is blocked unless it is deliberately overridden with a reason. So an expired part cannot be fitted by accident, and if it is fitted knowingly, the decision is on the record.
