I see there was an unfortunate incident on one of the taxi ways at tooraweena recently. 19/5/2023 OCC3272 Tooraweenah NSW Jabiru J160-D Jabiru 2200B STATUS: Under review OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was going to go for a short... STATUS: Under review OCCURRENCE DETAILS SUBMITTED TO RAAUS: The pilot was going to go for a short fly around the Tooraweenah area and was using the marked taxiway to enter the runway, there was an old drainage pipe underneath the taxiway which was broken and had formed a hole around 30cms wide and around 15cms deep. Taxiway had been freshly moved and hole was not visible and encountered a propeller strike with the ground. Because of the broken pipe the front wheel went into the hole and front wheel just stopped causing the prop strike. Front of plane was lifted off the ground when the propeller hit the ground.

I have no knowledge of this engine, just experience and knowledge of how hydraulic gear pumps and motors work. Air or oil they are just fluids. The roots supercharger is just a type of gear pump.

As described above if it only has the turbocharger it would not start or even be able to idle. It is a 2 stroke however the crankcase is not used to pump air into the cylinder like a Rotax 582. The other advantage of the turbocharger is to "unload" the crankshaft driven supercharger at high power setting, this fixed displacement pump would become a fixed displacement motor when the turbo comes on boost giving greater fuel efficiency. The supercharger would then drive the crankshaft like the power recovery turbines in a super constellation.

Volvo made some excellent vids about 20 years ago showing what happens to unrestrained drivers in truck crashes. It is a long way to the other side of a truck or bus. Education is the key. A sensor system will just be a PIA for the driver, a new way to have fun on the way home.

Skippy your logic that if less motorcyclist wore helmets, the state would be saved ongoing health costs is flawed. Minor crashes that with a helmet result in no head injury would become in many cases result in serious on going trauma. We see what happens when people are punched and fall backwards on concrete, very sad. I am guessing there are many times the number of minor crashes v major.

Propellers on GA aircraft are nearly always made of metal so no problem. Rain will strip paint from the leading edge fairly quickly.

That POH looks like the Australianized (and more shit) version of what the manufacturer would have provided. When I bought my Beech23 in 1996 it came with the legal "Australian" POH and the beautiful manufacturer POH. Some time later.... we were able to APPLY to casa to use the manufacturer version of the POH. I kid you not. Weight and balance. Upon acquiring my trusty Beech23 in '96 I did all the possible weight and balance scenarios as others above have mentioned. Max 140lb in the baggage and just skinny me with full and low fuel, no problem. Load from the front and don't exceed to 400kg useful load no problem. I have not done a weight and balance since then. Know your aircraft.

At work to isolate a cylinder ignition problems on Lycons a spray of paint on the exhaust headers 5 cm from the head, run engine in defect mode, left or right mag etc . Have someone watch the paint start to burn off. Stop engine,the defective cylinder should be obvious as less burned, colder.

Interesting that the super connie had power recovery turbines helping drive the crankshaft. In 1953, R-3350 Turbo-compounds were made available for civil use. Lockheed incorporated them into the L-1049C, which first flew on February 17 of that year. The R-3350-972-TC18DA-1 turbo-compound engines on the L-1049C had a new turbine system, the Power Recovery Turbines (PRT). Each engine's exhaust gas flowed through three turbines, increasing power by 550 hp (410 kW).

These guys have a turbocharged 2stroke. https://www.rotax.com/en/products/rotax-powertrains/details/rotax-850-e-tec-turbo.html

My guess is the air doesn't go into the crank case like a regular 2 stroke so it needs an external air pump at all times. Super charged for starting, turbo for altitude performance. Super chargers sap horsepower so that needs to be kept to the minimum required.

I really like 2 stroke engines. It might be a turn off for some potential buyers.

Mooney's are fast for their 180 or 200hp engines. An RV with the same engine is significantly faster, back seat, who needs that. Lancair 360 with 180hp even faster. The fixed gear RV is hard to beat. Van's total performance.

Beavers have three tanks in the floor. The selector has only four positions, front, centre, rear and off. Such a fuel selector would be perfect for your three tank aircraft. No external filler on one tank? Why?

The gear warning must not have been working or was incorrectly adjusted.

If I understand correctly your current fuel selector allows the option of selecting both wing tanks. This is not acceptable in a low wing aircraft. It only works correctly in high wing (cessna) aircraft. In a low wing aircraft air will enter the system from an empty tank regardless of the other tanks contents if both was selected. Piper, Beech, Van's RV aircraft never have the both option, only left or right or off.

Bit of a long video Skippy, perhaps you could summarise. I did see the bit when the engine was running rough over the mountain, no mention of fuel pressure or auxiliary pump operation which seemed a bit strange to me.

Yes, all good thanks

This page is now smaller, the what's new page is now to large for the screen on a Samsung s3 in landscape.

Farming, Fishing and Mining are eligible to claim back the fuel excise. Seems reasonable since that tax is supposed to be only used for roadworks. Avgas and Jet-A have a very low excise. Excise duty rates for fuel and petroleum products WWW.ATO.GOV.AU Fuel and petroleum products and the excise duty rates that apply to them.

I see the aussie Sling agent has registered the first sling tsi high wing in Australia and it has a 916 engine. Similar or better performance and useful load as the current model C182.

Not as close as this. It did fly away.

The biggest competitor to the 170D are the low hour, always hangared, as new used 170's. There is one for sale now, about 400 hours for $70k. Hard to compete with that.

I am not sure how you have advertised the event, nothing has come up on my Facebook feed. A Facebook search reveals one post from the mountain veiw motel, not many people would follow them. I only know the event is on from this forum. I have a prior commitment that weekend.

That would have been a 8v92T, the T means it was turbocharged into the gear driven super charger. Interestingly the tsi has returned 20-30 years later in some VW and other small capacity, 1.4l engines. There is nothing new.
