I know of a long time Libya guy who left 6 or 8 month back and I don't think it's gotten better since. Did you read about the US schoolteacher shot dead in Benghazi?
You could call Medavis in Malta and talk to someont there, they fly into Libya I think so they should have updated info.
Can you ask the people who want to hire you if you could talk to the last pilot who flew the aircraft.
Personally I would go right now and I spent some time there a few yrs back.
