Not much in the way of details yet. Shortly after takeoff from U42 (Salt Lake Airport #2), six on board, three houses on fire.

I see average useful loads from 1630 to 1730, +/- of course. On the generous side with 1700 lbs available, could have #500 in fuel, with 84 gallon tanks. After that you have people, baggage, & density altitude to work with. Even a ‘heavy hauler’ will reach a limit.
I didn’t look how far from the runway, which can be another clue. Sorry to hear, hope the best.

The article lists a 12 year old and 9 month old, I'm not sure yet WB is culpritI see average useful loads from 1630 to 1730, +/- of course.

Not all PA-32. Mine is only 1000lbs.
I’ve taken off high altitude at max gross, but I’m a turbo, and the bird has plenty of climb rate...
...On a separate note - some PA32 have really pathetic useful loads.. some you'll see for sale are around 1K lbs.. how you can call that a "6 passenger" airplane is beyond me. That's barely 4
Not the Lances, it's the saratogas. Seats are heavier, soundproofing is more comprehensive, and upholstery selection from the factory was also heavier. Similar dynamics befall the Textron offerings (g36 and 182t). Air conditioner options and turbo installations of course make it worse.1000 lb useful load in a PA-32? What is the airframe filled with that adds all the empty weight? Are these the Lances with retractable gear & turbocharger installations that are porking it up? . 260 hp to 300 hp to lift and move 1000 lbs? My old Cherokee 160 was only 20 lbs short of a 1000 lbs useful load.
Also a two year old that survived with minor injuries. It seems unlikely the aircraft was overloaded, but it is certainly possible.

Witnesses stated the engine sounded sick. Was a turbo lance. Wasn't there some issues with the early turbo pa-32's? Registration changed September of last year. I know witnesses are often unreliable in diagnosing engine so I'll take that with a grain of salt. Second turbo Lance down and second plane crash after departing U42 in the last 6 weeks.
One woman, a 21 year old nursing student heard the crash, grabbed a kit and ran to scene and started helping the injured before paramedics arrived and after as well. My hats off to that woman. Need more people like her
He just got his IR a bit over a week ago.

Yeah. That's a Cherokee 6. The D Alt was pretty tall that day....and he was fully loaded .

Living in Southern California I learned real quick that high DA flying is a completely new ball game.
Fully loaded. High altitude. High DA. Hottest part of the day.
Why as pilots we need to learn from others, sometimes we can learn from our own mistakes.
High DA and NA is fine if you have the right terrain clearance and are competent
The fact that three of six survived seems to say he did fly it all the way to impact.

Ain't never seen a retractable six... The early Lance was not a T-tail. Registration says it had a Tio-540 which I thought meant turbo injected...but I didn't think turbo was offered until 78 and registration is calling it a 75. The cowl doesn't have the turbo cowl.
Yeah, they ripped that post down.He just got his IR a bit over a week ago.

1.2 nm from the end of the runway to the crash site. Certainly it was flying; could have been on the edge.Just a note on terrain clearance: plenty of room to work with there. Flying south you can stay under the Bravo shelf and outside of the Provo airspace if needed and follow I-15 southbound for a good long while.
A question: if he was outside of W&B would he have been able to get much out of ground effect and travel 1.5 - 2 miles? Seems like there must have been at least another mitigating factor?

A Lance is pretty much a retractable Cherokee Six. The FAA, for reasons unknown, likes to put "TIO" on the engine, even when it is just an IO. I have seen that on numerous difference registrations when I know for a fact that the planes were never turbocharged.
An airplane was used to determine “book” numbers, but I’ve flown just enough new airplanes to know that they aren’t all built as straight as the “test” airplane.Performance is degraded by the age of the aircraft, and it could have been expected to perform this take off when new?
Or as the video said, pad performance numbers by 50%, even in a newer aircraft?
Is there a level of maintenance that can maintain "book" performance or is performance going to deteriorate over time no matter what?
There's a lot of variables, and while I generally love asi's videos, I felt this one left a lot out. The age of the airplane has little to do with it. If the airplane is rigged correctly and the engine is making rated power, they will perform pretty close to book numbers. The pilot also plays a huge part. Maintaining the appropriate airspeed and proper mixture adjustment are critical in marginal situations like this. The egt's they showed looked fairly close to what I see in my plane, although every engine monitor is different. As mentioned above, this was likely a function of several small errors compounding into one large tragedy.I watched that video the other day and was left in stunned surprise the plane wouldn't do what the manual said it would do. Now, please bear in mind I have yet to take my first lesson and have no experience piloting an airplane when I ask these questions.

The video puts a lot of emphasis on the tailwind takeoff. That would certainly have increased his ground roll distance. But once he left the ground would it have mattered? I've always thought that KIAS was all that mattered for climb performance and if you are able to get wheels up, then the wind direction stops being relevant (unless there was a sheer incident as you mention).We've been discussing this on the FB PA32 group. Speculation is either failure to lean for max power for that DA prior to takeoff (although report suggests he tried that in flight- maybe too little too late?) or tailwind takeoff as cause. I wondered if there could have been some tailwind windshear just as he got above ground effect/tree level that exacerbated it. From the report it sounds like he did due diligence even if he got uncomfortably close to POH limits. Most likely combination of older engine, less than perfect technique, lack of perfect leaning, tailwind shearing. Its never just one thing that gets you- swiss cheese analogy.
