Synopsis
Learjet 70 flight crew reported receiving a triple chime and a Red R Pylon Overheat CAS Message while climbing through FL340. The flight crew ran checklists and shut down the affected engine for a diversion and immediate landing at a nearby airport.
Narrative
While climbing through FL340; we got a triple chime and a red; R Pylon Overheat Crew Alert System (CAS) Message. I immediately grabbed the QRH and handed it to Person A; who looked up the proper checklist. We ran the short checklist which consisted of NAC (Nacelle) Off; N1 reduce and fly out of icing conditions. We decided to level off during this process at FL370. The Overheat CAS Message remained illuminated after bringing power to idle on the right engine and [the Captain requested priority handling] and requested a left turn toward ZZZ1 which we were given. I called [a company pilot] up to the cockpit and we began a descent. [The company pilot] agreed that we had performed the correct checklist and also agreed that the next step was to shut down the right engine. We shut down the right engine according to the checklist. The Overheat CAS Message remained illuminated approximately 5 minutes after shutting down the engine. We got vectored on to the ILS XXC at ZZZ1. ATC asked if we would like the fire trucks rolled and we did. We made and uneventful landing and taxied to the FBO. There was no external indication that there had been a fire or bleed air leak.
Second reporter narrative
While climbing out at 41;000 ft.; got an R Engine Pylon Overheat Red Warning message with a Master Warning Alert. We requested to level at 37;000 ft.; and ran the QRH with the message persisting which led us to shut down the right engine. We requested and got vectors to ZZZ1 and began a descent. The R Engine Pylon Overheat Message appeared again and went away after a minute or two. We [requested priority handling] and prepared for arrival. The approach and landing proceeded uneventfully.Nothing to add. Hard to avoid this type of situation. Suggest incorporating our actual events into recurrent training.
