I wouldn't be surprised to find there is a procedure/chemical that has you spinning it up slowly and spraying it. I mean ingested insects must be cleaned.

Not how it would be handled. It sounds plausible in theory but in practice it wouldn’t work.

Fan blades in the various compression and exhaust stages were bent, chipped, and otherwise destroyed. Slowly restarting the engine would just cause further damage to the unit when these broken parts start moving. The forces exerted on the blades when spinning would cause them to start coming apart and potentially exiting the engine as shrapnel, although this is unlikely (engines are designed to contain a catastrophic failure to prevent this exact scenario).

There are basically two options at this point. The first is disassembling the engine and assessing the damage to determine the cost and likely hood of repairs. Something the size of a human body is going to wipe out basically every piece of internal hardware.

The second option is to just write off the cost of the engine as a loss and scrap it.

I saw photos of the accident and my money is on option two. There was literally nothing left larger than the size of a 50 cent piece. You wouldn’t even know what happened based on the photos unless someone told you.

Very sad situation and sad remind of the dangers planes pose on the ground. She didn’t suffer, death would have been instant.
