Re: crash today near bear valley idaho (valley county)

What troubles me the most is the LACK of warning from the pilot to brace for a crash... The passengers had to fend for themselves and that is unacceptable in my book. IMHO

Most Stinson 108-3s have a usefull load over 1000lbs and a gross weight of 2400lbs and 50 gallon fuel tanks. So he might not have been over gross. Obviously too heavy for the conditions though.

Incredible...

What could the pilot have done better?
(once he realised he shouldn't have committed to the takeoff and was already airborne I mean.... )

It feels more like damage control, doesn't seem like he had much performance to work with.

Re: crash today near bear valley idaho (valley county)

Took off out of TRK few weeks ago,89 degrees 5900ft field elevation .4 jumpers onboard a 206 with a 550 in it... wind going around in circles....1000lbs of people plus 200 lbs of gas........1700 lbs useful load (Give or take a few lbs)......sounds pretty reasonable to me eh? climbed out at best 200fpm. Got a few good pockets of lift but it was not fun. Made it to around 12.5k and kicked them out. I cant imagine there being no backpacks or other misc stuff besides the four people in that Stinson.Crazy thought process on that one....I cant believe they lived !!!! Scary video :?

Re: crash today near bear valley idaho (valley county)

O-300 powered here in Nevada, every summer takeoff can feel like that one... But damn...

Gotta have some Plan B's locked and loaded, or a shutdown point set in stone where you say "screw it, I'm gonna stay here and drink beer." If not, like this guy, you aren't the pilot, you're just a passenger.

Re: crash today near bear valley idaho (valley county)

looked an awful lot like a south departure out of JC...that time of day up here its damn nasty...theres been a few stinsons tippin' over up here lately...i hate it! glad they are all seemingly OK...that was a big fall to have not gotten killed...i'm OK with goin' in that time of day, but cant remember the last time i departed at that time...like gump said, if she aint a positive rate of climb thing goin' on, stuff it back down and have a cold one for an hour...

Re: crash today near bear valley idaho (valley county)

Hot weather + Density Altitude + Probably heavy loaded plane + Not aborting earlier on in the obviously difficult take-off= Video on Liveleak - Thanks for posting. It's a good reminder.

Re: crash today near bear valley idaho (valley county)

Sheesh! I doubt I would have done anything different at the point of impact or had anything to say about bracing for impact, I go over that at startup because I know I don't say much when the SHTF (If the trees coming at you aren't already warning enough....) but I'm sure I would have turned around in that meadow to either circle and build altitude or go back and land. And... WTF is up with the guy filming all the gore? If you're in good enough shape to do a documentary, you're able to get your ass in the plane to scrounge up blankets, flares, a radio , water, first aid kit or something. Anything would have been better than zooming in someone that needs some first aid instead of giving him some help.

BTW, Did anyone notice that the mixture was full rich?

Re: crash today near bear valley idaho (valley county)

I logged in to ask about that mixture, but you beat me to it.

Seems like there wasn't one good decision made this whole time. Overweight, high DA, mixture rich, didn't take the hint when the plane came down the first time on the runway. I know it is easy to armchair quarterback, but c'mon here.

Not sure what airport they were at or Density Altitude but it looks like Sulfeer Creek -at gross or near could
have 0 or very little climb performance -especially with 150 hp . Glad they made it but maybe they should been lighter for flight >>>> or much earlier in the day (cooler ) .Density Altitude vs 150 hp is a no win situation at gross.

Re: crash today near bear valley idaho (valley county)

I didn't hear any of the audio from the intercom - it probably wasn't recorded. The GoPros - especially the older ones like mine - have internal mics and it's impossible to connect to a mic or other audio source - so they would have had to have a separate audio recorder to get the radio mix. I'm sure we'd have heard all kinds of announcements when the SHTF if they'd been recorded. All I can make out is the internal mic of the cameras so with engine and wind noise you would never hear people talking into the mic on the com.

In the slow-motion replay of the moment of the crash, is the pilot holding an Ipad? :shock:

The iPad is mounted on the yoke. Shows it right at the start of the video.

As far are the turning back is concerned, he did slightly turn to follow the gap in the trees. I think he would've been able to make a wide turn before getting that far along. But I don't know the type, so not saying for sure.

Re: crash today near bear valley idaho (valley county)

Weird.....
Plenty of mention of low power, the need for more power, pretty tight on power....

Am I the only one that's noticed that with enough DA your wings, prop, and mind don't give a hoot how much power you have?...

That was a rhetorical reminder for those of us fortunate enough to have great big burners up front that we *think* is always gonna save the day...


Take care, Rob

Re: crash today near bear valley idaho (valley county)

I agree with rob about the DA , but I'm willing to bet if he was driving a turbo charged 185 he would have out climbed the trees.Having the mixture all the way in probably didn't help much.(maybe he had a turbo io360 in that thing) who knows?would be interesting to hear the pilots response to the mixture question.

I'm convinced that the dangers of high DA continue to be a contributing factor to crashes because they are just one of those things that people unfortunately have to learn the hard way. Even though we're quizzed on the concept of density altitude and performance degradation gratuitously in the FAA curriculums, it seems that it doesn't make an impression on pilots until they've experienced it first hand. The way it's taught is very academic, students supply the right multiple choice answer, but the tangible risks are something that are never addressed in practical training. Poor climb performance while in cruise flight...say 9,500 climbing up to 11,500, usually just doesn't register because there isn't terrain staring you in the face. Also, many pilots don't experience the performance of their aircraft at max gross. How many stories have you heard about the low time pilot who buys a HP aircraft, and flies it alone 99% of the time...then one day loads his wife and another couple into it with full fuel and tries to takeoff from a high and hot airport? Classic.

I was chatting with ChrisG about this topic this morning, and I admitted that if not for my formative flying years spent reading this forum, with primary focus on mountain flying, I would probably not be as aware of a lot of mountain flying dangers like high DA. We take a lot of our knowledge for granted because we read it and discuss it daily here. Many pilots do not, and they find themselves in a scenario like this one, either completely ignorant of the performance limitations of their aircraft, or pressured to return 3 people to their schedules, and go for it with high hopes. Skills like thermalling and circling can't be relied upon when you don't have the lift margin to even bank 15 degrees.

If you witnessed this guy land heavy at Bruce Meadows, and he was prepping for takeoff, would you approach him with a little free advice? What do you say? We're a proud bunch, it's tough to hear criticism of our decisions, especially in front of your pax.


What i have learned is even with friendly advice, the person is going to think your an a$$hole and i know what I'm doing and i don't need advice from anyone. Unfortunately, you just need to stand clear.

Well, it's excess power. What power setting do you need to maintain altitude at Vx (not min power)? How much power do you have available at altitude? The difference between the two, divided by the weight of your plane, yields rate of climb at Vx. It's that simple- try it on your airplane.

A 182, at the same weight, will obviously out climb a 172 at Vx by about the amount I described above. More excess HP, more climb. Climb *gradients*, unfortunately, flatten out by the same proportion for all normally aspirated airplanes, and also flatten out (to a lesser degree) for 'charged machines.

(ROC/TAS) gets worse for the numerator and the denominator in normally aspirated planes, and only worse in the denominator for 'charged engines.

If you take off in your plane form your home field with 70% BHP, and hold it on the ground to use up 65-70% more runway, you'll get roughly the same feeling as the chap at Bruce Meadows at 9000'+.

I think the keyword here is "mind." We all know that enough power is enough. Jets fly and climb fine up in the wee density of the flight levels, but they have the luxury of being well clear of the visual indicators of groundspeed, so they focus on instruments.

If the DA is really high, that big turbo charged powerplant + JATO units will get you going fast enough, but all the standard visual cues are going to make things appear as if they are going really fast...because they are. Groundspeed is higher, effective climb angles are shallower as a result of the same airspeeds that result in Vx or Vy. The mind doesn't like this.
