Back to the original intent of the thread, this is what we know:
Since the last week of December Key Lime has had two accidents and one Metro Engine failure. We don't know much about the first one, but because I know the skill of the pilot involved I'm very curious to see what the NTSB digs up.
As to the Metro Engine Failure, stuff happens. Even Garrett engines fail occasionally.
As for the Navajo, fortunately the pilot walked away, but when the final report comes back I'd be very surprised if it wasn't fuel related, either not enough gas in the airplane when it left, or stupid pilot tricks with the fuel selectors, which is a really stupid simple system, from the perspective of the pilot.
I'm no math whiz, but quite honestly I don't see these three events happening in close succession as statistically significant. Stuff happens.
As a Key Lime Alum, would I recommend you go work there? It's really not the greatest company in the world. Kinda sucks sometimes, but that has more to do with the schedule than anything else. They do push you, and they'll blame UPS for it. Say no too many times, and well, figure it out. If it's legal, plan on going. If it's not legal, plan on departing to a different airport, then changing your destination enroute if the wx improves.
There are plenty of guys that started there as piston guys, moved into the Metro, then either moved on, or stayed for a while. If you want to live in Denver, 5 of their 6 piston runs would have you in DEN a fair amount of the time, but the schedule is pretty brutal. Very few of the Metro runs would give you significant time off in DEN. If you want to live in one of their outstations, a Metro run would have you there a lot. There are several senior guys with families in their outstation that will be there a while.
If you don't live in DEN and want to experience night freight (which in my opinion is a great way to make yourself a good IFR pilot), go to AmFlight.
