When it is needed
In a dispute about supply, transfer of aircraft or equipment, damage found or the scope of defect assessment.
What we examine
- Aircraft
- Units and components
- Defect assessment data
Materials to prepare
- Identification documents
- Operational documentation
- Handover and defect assessment records
- Photographs and operating history
Sample questions
- Is the submitted object unambiguously identified?
- Which defects can be established?
- How do they relate to the documentation provided?
- Are the data sufficient to assess the presumed cause?
- Which additional examinations are necessary?

How the work is carried out
- Checking the object and brief
- Agreed inspection and analysis
- Comparison of technical signs
Result
A report on agreed characteristics and identified defects, stating the examination boundaries.
What affects the conclusions
An independent examination does not constitute release of aircraft or equipment into service or confirmation of airworthiness.
Frequently asked questions
Can an individual component be examined?
Yes, if its identity, condition and handling history are established.
Is access to the aircraft needed?
This depends on the task. Access possibilities and conditions are determined before the contract is concluded.
Component record and traceability of its history
The examination must establish whether the submitted documents relate to the same object. A part type designation and its individual number serve different purposes: several specimens may share a catalogue number. Photographs of markings are therefore compared with the technical logbook and installation, removal, repair and handover entries.
A separate chronology is useful for each component. It states the identifier, operation date, recorded operating time, basis of the entry and the document supporting a condition change. Information in different units or with different precision is not combined without explanation.
- Model, type and individual object identifiers.
- Source of provenance and completeness information.
- Installation, removal, servicing and repair records.
- Data on the reported defect and conditions of its discovery.
- Information about storage, transport and changes after removal.
The presence of an accompanying document and its relevance to a particular part are checked separately. Actual observed condition is also distinguished from history reconstructed solely from entries. If an identifier is damaged or documents contradict one another, this becomes a separate examination question.
This set helps frame a precise task: are the designations consistent; which handling stages are supported; which condition information is missing? Checking these circumstances is not independent confirmation of airworthiness or authorisation to install a component on an aircraft.
If repairs involved several identical units, each entry is linked to an individual number rather than merely the model name. A lot or type designation does not replace identification of a particular removed component. For a unit transferred between organisations, retain a list of accompanying documents and note historical gaps: these limit conclusions about which object a previous check result concerns.
