No new surprises or information in update 3 except that it is time that this military route should be stopped. The separation is far too small and a small error can and has lead to disaster.

I'd say the Blackhawk altitude on the transcript probably came from ADSB received data as it was available almost immediately after the collision. This will need to be corroborated with data from the FDR. Information from both FDRs will provide a much clearer picture of the whole event.

The Bolly hubs are precision CNC formed, gold anodised Duralite and the blades are micron perfect fit. Every bit of hardware down to the washers is fully documented, with batch numbers, weights etc as of course it should be. They are quality products locally manufactured and are up there with the best in the world. They all come with detailed instructions & charts on assembly, installation, balancing, pitch adjustment etc. There are not many Australian manufacturers left that I can say that about them.

I still have a wooden prop for my 6cy Jab engined aircraft but it isn't a patch on the ground adjustable 2 blade Bolly Bos 5 I have installed now. The Bolly is lighter far more chip resistant and tunable to they type of flying I do. It has several weaves of carbon fibre and reinforced with glass strands and kevlar with a toughened replaceable leading edge.

Quite a few holes lined up in the Swiss cheese model. Late change of runway for the RJ to a much shorter runway requiring a right turn before left hand line up. Vertical separation was only 300 feet maximum & the Blackhawk was above the maximum allowed 200 feet at 300 feet while the RJ was descending from 500 feet. Blackhawk was on a different frequency & couldn't hear the RJ. Blackhawk confirmed visual of the RJ exonerating ATC. Blackhawk confirmed it would pass behind RJ. Aircraft & City lights tend to blend in to one another. Blackhawk pilot may have been using NVG & if so had no real depth perception & could have identified another aircraft behind the RJ thinking it was the RJ. TCAS is disabled below 1000 feet & no aural warnings below 500 feet. That's 8 identified by Juan Browne and there could be more but all those factors add up to a recipe for disaster.

It was TIC hence the laughing emojo

So if your plane is painted, don't fly during the day and if it is made of metal don't fly it in high humidity fog, mist or rain. Keep it in the hangar and never let it out. Then you can just let it waste away from creeping corrosion, dust, dirt bugs, rats etc.😀

Who cares? It all seems like marketing hype to me. So MOGAS is anything that isn't AVGAS.

I used a Dulux Industrial 2 pack to paint my aluminium & fibreglass aircraft when I built in in 2015. The paint still looks as good as the day it was done & I've never polished it, just wash it with a car wash & wax.

The airstrip near Macksville is to the West of the Pacific Highway and if you know where to look you could see it as you drove past. It is a private airstrip. It is over 10 years since I had any knowledge of it so it may no longer be there. No idea about Nambucca. There is another private strip near South West Rocks.

I chose the tip of the spinner as the datum when I did the W&B. The advantage of this is that is a fixed point as far as you can go forward on the aircraft so it is easier to do another one somewhere else using the same point. It is a pretty common practice. My COG limits are 15% to 30% aft of the leading edge wing root cord. I have a forward baggage area and one behind the seats and a forward fuselage fuel tank. Wing tanks are within the COG limits. It is all in the phone & easy to calculate when I chuck things on the scales before heading off. If I am bringing something heavy back with me I need to know what it weighs or it gets left behind.

Sceet/Scat is what silicone flexible air ducting (1 or 2 ply) hose is known as in the Aviation industry. Specs are identical as are the temperature ratings but price from aviation suppliers is more than double. the sceet or 2 ply has higher temperature ratings -60c to +300c compared to -50c to +250c.

I bought mine (No 9 Sceet) from an automotive supplier in Sydney via Ebay. It cost $45.00 for a metre length & came doubled over to fit in a half metre box so 180 deg bends are easily done.

Yeah it wouldn't be ambient temperature unless you like to fry.

I just cut it with a Stanley knife at 90 deg & where the cut intersects the wire coil I cut that with side cutters. The spring tension will cause the cut end to distort a bit from round but that doesn't matter as your hose clamp will be back further to create a good seal.
