ARFE

Aircraft Records Forensic Engine

A due-diligence platform for the analysis of aviation technical documentation and the evaluation of aircraft components. ARFE ingests unstructured records, reconstructs the maintenance history of an asset and calculates its remaining value and financial exposure, with every figure linked back to its source document.

Where it is used

High-stakes moments in an aircraft's life.

  • Lease redelivery

    Checking return conditions against the records before the dispute, not after.

  • Pre-purchase inspection

    Records review that scales to the size of the binder set and keeps its sources.

  • Portfolio review

    The same model applied across a fleet: residual value, upcoming LLP events, compliance status.

How it works

From records to an evaluated asset.

  1. 01

    Ingest

    Bulk intake of scanned and digital records in any format. Pages are classified and indexed.

  2. 02

    Normalise

    Part numbers, serials, dates and cycles are extracted and reconciled across operators and MROs.

  3. 03

    Model

    Facts are stored in a versioned ontology — objects, links, events — each with page-level provenance.

  4. 04

    Reconstruct

    The asset's timeline is assembled: installations, removals, life-limited part cycles, AD and SB compliance.

  5. 05

    Evaluate

    Remaining potential and financial exposure are calculated from the reconstructed timeline.

  6. 06

    Report

    Gaps and conflicts are listed as findings with their sources, so they can be checked and discussed.

Ontology first

The model is the product.

The interface is replaceable. The clean, versioned, source-linked model of the aircraft is not — once it exists, it answers questions beyond the transaction it was built for.

Provenance
Every extracted value links to the page and document it was read from.
Versioning
Corrections and new evidence create new versions. Nothing is silently overwritten.
Quality gate
Untraceable or low-quality data does not enter the model, even when convenient.
Standards
Modelled against MRO data standards such as ATA Spec 2500 and IATA LLP traceability guidance.

Scope and liability

Data intelligence and commercial analytics, not certification.

Yellowhammer operates within the domain of data intelligence and commercial analytics, outside the certification and regulatory scope of aviation authorities such as EASA or the FAA. ARFE does not issue certificates of airworthiness or certified asset appraisals. Its outputs are decision-support inputs for the parties to a transaction, and contractual liability limits are defined accordingly.
