What kind of tampering are you looking for? I'm curious.

I thought about the comment by another of hooking up something in the
unit. Most likely the person would use alligator clips or some other
intricate connector. Do you think you would be able to see the scratch
marks left by this connector? What else are you testing for? Some code
changes or board modifications? More likely someone would hook through
the communication connection outside the unit. Then you would never know
they were doing that would you when you did the 'in hand inspection'.
How about I take a picture and send it to you while you are connected to
the unit?

There is not much room inside the unit for this kind of modificationl Nor
as another put it would someone really invest the time and money?

Hi Marc,

Good point. I really would need to have the unit in hand.

Open up case, insert $2 microcontroller between GPS receiver and flight

recorder logic board, close case, call up manufacturer say "hey my
flight
recorder unsealed itself", reload key, go set some world records.

The manufacturer or designated agent is supposed to inspect the
interior

of the unit for tampering before resealing. Otherwise, there's not
much

point to sealing it in the first place...
