Synopsis
Challenger 300 flight crew reported a Smoke In Cargo CAS in cruise and elected to request priority handling and divert to make a precautionary landing.
Narrative
In cruise at FL410 over ZZZ we got an EICAS message for cargo smoke. There was no smell or sign of fire so Captain went to see if fire was present and I put on O2 mask. Upon his return he reported smoke in cargo area to me. We requested priority handling and initiated a descent for recovery at ZZZ1. We were quickly vectored in for a visual approach to Runway XX ZZZ1. Services were on the spot for us on landing. I prepared for an evacuation during approach. We elected to clear the Runway and stop on Taxiway as we still had no visible sign or smells. As we stopped the pax reported smoke now present. I got up and opened door and directed them down and to a safe area. Captain shutdown and helped direct pax and I showed fire rescue cargo area from inside plane. They requested I open the outside cargo door and I did so. They started pulling the luggage out looking for source. There was a 3-4 inch burn mark on left side of cargo bay wall and bedding bag had some burn marks but no flames were present. Passenger were picked up by FBO and we took the plane back to the FBO with fire rescue escort. Aircraft is in maintenance with Company now. Our Company was notified and in contact with us through all on ground. ATC did a great job in getting us down safely in a high traffic area. Fire rescue response was also great. The Company was very responsive and helpful in guiding us through events.
