Remote borescope inspection review: how a second set of eyes works

When it is used

A lessor wants a second opinion on an operator's inspection before accepting the engine. A buyer wants findings on a seller's video checked before paying for a full pre-purchase inspection. An operator's own technician wants confirmation of a borderline finding. A fleet manager wants a consistent read across inspections done by different people at different stations.

What to send

The video and stills labelled by engine stage and port, the engine's identity and status, the AMM task that was followed, and any findings already recorded. The better the labelling, the faster and more useful the review.

What the reviewer does

Works through the footage stage by stage; identifies findings the original inspector did or did not record; sizes them where the footage allows (a measurement tip in the original recording makes this precise, a plain camera does not); compares them with the AMM limits; and writes an opinion that states what was seen, what could not be judged from the footage, and what should be done next.

What it cannot do

Replace a physical inspection where a transaction, a lease or a release requires one. Size a finding from footage recorded without measurement. See what was never recorded. A good remote review says plainly where its limits are.
