Rough transcript from LiveATC. Non-accident aircraft comms not included.
HJ823: Hop-a-jet 823 is with you on a right downwind for a 5-mile final ah runway 23 KAPF: Hop-a-jet 823, roger, make a right turn back toward the airport, [?] departure ahead Challenger jet, runway 23 cleared to land, wind 220 at 12, gust 16 HJ823: Alright, Challenger jet departing, we’re turning back towards the airport and cleared to land runway 23, Hop-a-jet 823 HJ823: OK, ah, Challenger, ah Hop-a-jet 823, lost both engines, emergency, making an emergency landing KAPF: [?] got that emergency, cleared to land runway 23, is that Hop-a-jet 823? HJ823: We’re cleared to land but we’re not going to make the runway, we’ve lost both engines. |
Over 2,000 fpm descent half way through the base to final turn. The fire seems to indicate this was not fuel exhaustion.

What the heck other than bad fuel or no fuel takes out both engines at the same time?

Where did it top up fuel last |

A similar issue (corroded 5'th stage check valve sticking open due to extended duration storage) was causing multiple in-flight engine shutdowns at top of descent on the 737NG after bunches of them were poorly stored at the beginning of COVID. It is complete pure luck that there were no dual engine flameouts. https://www.federalregister.gov/docu...pany-airplanes |
Nah… quick quick turn in Columbus, respectfully I would seriously look at their fuel numbers for an out and back.
(12 years on 604/605 myself) edit to add, I dont want to read too much into the flames.. remember there is always an amount of unusable fuel that remains so hard to say at this point |

Looking at the airplane's pneumatic diagram, one way the engines are tied together is through the 10'th stage bleed manifold, but there is a check valve that should isolate them. A bad 10th stage bleed check valve could cause a compressor stall and engine flameout at low power settings when you start the APU, which could account for an engine failure in this phase of flight. Having 2 check valves on 2 different engines fail on the same flight? That seems extraordinary unlikely. It was a quick turnaround at OSU so they would not have had time to do any maintenance, so a common mode maintenance failure seems unlikely.

Surprising to see that cars just pass the burning aircraft without stopping to offer help.

Glad to see at least one of the pax managed to escape with her hand luggage !!!

And via the baggage hold door non the less.. only option really on that side considering the angle and flames

no, you dont transition the bleeds(its manually done in the 604/5) until APU is up and running and also switching 10ths off is approved for ops if you have no APU (limitation of pulling two bleed sources at same time off engine) if you want to use Anti-ice for takeoff or landing

No toggle switches like the Global.. they are simply triggers on the back of the thrust levers that need to be pulled to go to cutoff.. hmm so you are thinking like that Falcon20 crew many years ago with worn latches and flamed both out when going back to idle?
