Synopsis
CL-30 flight crew reported diverting to an alternate airport after shutting down the left engine following EICAS messages regarding vibration and ITT exceedances.
Narrative
I departed ZZZZ as the pilot flying (PF) on a revenue flight on Aircraft X with X passengers and Y crew members. Normal taxi out; take-off and departure headed to ZZZ. Approximately 2.5 hours into the flight at cruising altitude FL450 the aircraft broke into a strong loud and continuous vibration and shaking. The event was then followed by EICAS Indications of L ENG EXCEEDANCES of VIBRATION THRESHOLD EXCEEDANCE and Interstage Turbine Temperature (ITT) THRESHOLD EXCEEDANCE. We; the crew; completed the appropriate QRH checklists and ended up shutting down the L ENG. We [requested priority handling] with ATC and requested a divert to ZZZ1 for the longer runway and plentiful services. I was very familiar with ZZZ1 having been based there for many years working for a different carrier. We were given excellent headings via waypoints and vectors to ZZZ1 by ATC. I performed a single engine approach to the ILS and a single engine landing. We stopped after pulling off and clearing the runway and were immediately met by Crash Fire Rescue (CFRs). They inspected the exterior of the aircraft and noted no irregularities. We were cleared to taxi to the FBO where we met again with CFR as expected and Customs. I called Company and Maintenance and completed the appropriate paperwork. I provided the passengers with additional information as to what took place and what to expect from that point. The passengers were also in contact with client services and the Lead Passenger was informed about hotel accommodations for the night.
Second reporter narrative
Around or near ZZZZZ we encountered a strong vibration; then an L Engine Exceedance Crew Alert System (CAS) message followed by a L Engine Vibration CAS message. We observed the Interstage Turbine Temperature (ITT) was extremely high. We followed the QRH; shut down the engine and prepared for a single engine landing. ZZZ1 was the nearest airport with long runways and excellent emergency services. We decided to divert there. Landed single engine.
