A reminder of the importance of W&B

Well worth a read especially if you use an electronic W&B calculator, not to mention the incorrect use of standard weights. 4 POB with serious injuries, could have been a lot worse.

I don't understand how the use of an electronic W&B calculator had anything to do with the accident.

Im with you i dont think it does unless it had incorrect weight and balance moment data, the reason it had an aft cofg was due to use of standard weights which put to much weight in the back putting the aircraft completely out of the envelope at full and zero fuel weight

It is not clear that W&B was actually a major factor in the accident.

The report is all but silent on the fact that the aircraft was well to the right of centerline and apparently engaged in abrupt, very low level, low speed maneuvering to pick up the centreline from an almost impossible position.

That is a perfect recipe for an accelerated stall, so close to the ground that recovery is impossible, irrespective of CG.

Yes agreed dangerous situation at the best of times,the atsb w&b plot shows it clearly aft of the envelope by a good margin due to weight distribution

Seems the pilot was quite knocked up in the crash. The photo looks like it pretty much folded up; I'm not sure how anyone got out of that mess!

It would seem pilot error due to an unstable approach from distraction and decision to not go around and instead slip a heavy single at low altitude, he was however unknowningly flying outside the cog envelope so it was probably an accident waiting to happen later, its very sad because it can happen to any pilot, you dont know what you dont know until you do and sometimes that comes at the worst time, im not casting judgement i might have done the same in those circumstances but i Certainly wont now, just gone in the memory jar.

I assume you meant to ask, what do I think what was the cause?

As for who... if it wasn't a passenger then who else could it be other than the pilot? !!

I don't know what the cause was because I wasn't there. The ATSB didn't tell us and they are smarter than I so who am I to judge eh?

No, I just asked the same question you posed on another thread so I thought you could provide your own answer.

Oh if you are referring to the KingAir thread that was asked because Mr X said that he actually knew why it crashed. I made no such statement here.

I was taught as a very junior student of flying that you do not go even a pencil line thickness outside the W & B envelope in normal operations. I was told to treat this as non negotiable.

A sound practice for the line pilot. This presumes, of course, that the loading system is kosher.

As a side note, there is a thread on Bob Tait's website relating to trimsheet loading systems which may be of value to the Standards side of the discussion in the present thread.

It seems that there might be a few examples out there in the Industry which don't quite pass muster.
