Vmc is the speed where a twin engine propeller plane doesn’t have enough air flow over the rudder to counter act the roll and yaw that is being created from having too much/full thrust on one side of the plane and now excessive drag on the other due to merely a windmill on the other.



Probably a dumb question, but this isn’t a problem on a jet engine in the same situation?

Thanks for the reply. I just remember something similar happened that caused a plane crash in a show on crashes. Wish I could remember which crash if was.

ETA: here it is geauxxx. This is the type of scenario I was thinking about. Not sure if this would even be remotely a possibility.

Lauda Air Flight 004

Well for one they are still extremely rare.

But there are several factors. Airlines have this shite down to a science and are much more heavily regulated than charter or private flights. They have very robust maintenance and pilot training programs with a lot over both company and government oversight. Also airlines fly the exact same routes at the exact same time everyday. The schedules are known well in advance. Very rarely does an airline pilot encounter something new. The private operators don't have that. Some owners skimp on maintenance or pilots. Add that to the fact the King Air is generally considered an entry level airplane for most professional pilots.

I have no idea if that was the case here. The vast majority of owners and charter companies take maintenance and pilot training very seriously.

I edited my last comment to show the scenario I was thinking about was Lauda AIR Flight 004

Reverse thrust on jets and props are completely different. I'm not a jet pilot but I'm pretty sure most jet engines have clamshell like pieces that close behind the engine redirecting the thrust forward. On props with reverse capability the actual blades rotate so that they push the air forward instead of backwards.

On the King Air specifically I cannot imagine how the prop would go into reverse uncommanded.

appreciate your input on this, horrible accident and the professional opinion you offer while being respectful of those involved and the sometimes stupid questions really makes this sort of thread educational

It's all just spitballing of course until the actual investigation is completed. But incidents like this always make me dive back into the manuals. They say speculating after accidents is bad but speculating makes me a better pilot I think because I go into the books and try figure out what could have gone wrong. What makes sense and what doesn't. So I know my airplane better today than I did a week ago because of this crash. Probably of little solace to the loved ones of the victims but hopefully it will help save some lives in the future if something like this happens to me.

I agree. I know my questions are dumb, especially for those familiar with aviation but I wanted to know and he explained it thoroughly without making me feel stupid. I am very into plane crashes but still not familiar with most of it. Thanks Geauxxx for the answers.

Left engine failure. I’m assuming the sudden yaw was too much to handle at such a low altitude and speed

I knew all of those women and competed against a few several times a year in tennis. They will be greatly missed on and off the court.

I knew Brian better than I knew his wife, Ornella. But she was all class and a very sweet woman. 2 of the most giving people I've ever known.

Have you listened to the tape? If so where can I find it.

Looks a lot to me like an inexperienced pilot with a left engine issue. Those little planes usually jump off the runway, that plane seemed to struggle to gain speed on the runway and altitude. Pilot likely hesitated and tried to gain speed and altitude until it was too late, instead of just crashing off the end of the runway on the ground or maintaining low altitude going straight until the issue could be troubleshooted further.

All crashes result from insufficient altitude.

I’m sticking with left engine failure resulting from a fuel issue.

I don’t think you’ll ever find me in a small plane



I have flown in King Airs a few times. Not bad but I can understand why someone wouldn't want to. That being said, they are one of the safest small prop planes ever built IIRC.

I flew in one once and the whole time just watched as a "small" oil leak splattered all over the wing. Was a bit concerning but nothing happened thankfully.

Pro tip: Don't ever fly in one between Vegas and Cali in July or August. The heat thermals coming off of the mountains pushing you up and down can be a crazy roller coaster. Nothing like losing several hundred feet in a second.

From what I have been around it's pilot error and maintenance issues mostly. The two most important parts of a private aircraft, but often one people try to save money on.
