Skippy, I blew the tyre because it was an aged Chinese tyre showing signs of degradation, and I shouldn't have left it on the trailer for the trip. The trailer was loaded to the full 2000kg trailer gross limit. The suspension is a 4-spring leaf suspension with a middle rocker bar, and fully greased shackles. It's as good as they come for a regular-duty tandem trailer suspension. It has over-ride drum brakes on the front axle only, a fully-legal arrangement in W.A. They provide adequate braking under nearly all conditions except extreme conditions.

Blueadventures trailer looks like a handling disaster waiting to happen, to me - due to the poor positioning of the wheels/axles in relation to the trailer frame and length. Trailers should always be constructed with the axles mounted central to the frame - or even better, 50mm to 100mm behind the centre point of the main frame. This ensures good handling, and a resistance to tail-wagging, especially when loaded. A trailer with axles mounted forward of the centre point of the trailer main frame is a guarantee that tail-wagging will result the instant the trailer is loaded, and hauled at highway speed. You have to remember that a tyre blowout on a rear tyre (always a likelihood), will result in immediate adverse handling, and initiate a tail-wagging event. I've just had that happen to me with a tandem (1.8M x 3.6M) enclosed trailer that is professionally well built with centrally-located axles. I was loaded to the limit, blew a rear tyre at 100kmh on a downhill run, and I can tell you, it took all my trailer handling skills to keep control of it. It was extremely fortunate at the point where I blew the tyre, the highway was extra wide and there were 3 lanes with a passing lane going the other way, so oncoming vehicles were well out of harms way. As it was, I was over the centre line trying to keep control of the vicious tail wag while trying to come to a halt with one basically tyre-less rim.

I think it would be useful to study up on the number of aircraft crashes where radio calls featured large in the accident scenario. In particular, radio calls that were missed, and radio transmissions were were talked over by the other crash party making a call at the exact same time. The most disastrous aircraft accident in history (Tenerife) was largely caused by an incoming call being talked over. Then there's the lack of understanding of what was said, and what was meant. Thus we have standardised radio procedures and phraseology. The conclusion would have to be, that more calls, not less calls, is a big safety factor - especially where there's an ongoing lack of certainty in aircraft positions and intentions.

The design criteria behind the BAE146 was straight-out quietness, to ensure they could run U.K. to Europe and return outside noise curfews. Plus, the little vacuum cleaner engines (Avco-Lycoming ALF502's) were plentiful and cheap, being a derivative of the Lycoming T55 that powers the Chinook helicopter. In addition, the design called for as much "off-the-shelf" componentry as possible to keep the construction and running costs down. And finally, they were designed for steep departure and arrival angles, so they could slot into tight airports in congested areas. Overall, they were a success by anyones measure, and they were produced for nearly 20 years. And yes, our dear Monarch would've had his licence lifted if it wasn't for the fact he was the Queens favourite son - after he landed too fast and too high, and shat himself, and locked the wheels and wrecked the tyres with excessive braking, when he overran an airstrip at Islay, and ended up bogging his machine. The Captain got a reaming for not taking over when it was obvious Charlies landing skills were deficient. I guess he was reluctant to tell a future Monarch he was taking over. /graphics/ICAOtype/B461.gif Accident British Aerospace BAe-146-100 ZE700, Wednesday 29 June 1994 ASN.FLIGHTSAFETY.ORG A BAe-146-100, operated by the Queens Flight, was substantially damaged when it was involved in an accident at Islay-Glenegedale Airport (ILY/EGPI), United Kingdom.

Wing Aviation Pty Ltd drones - coming soon to Melbourne
onetrack replied to SGM's topic in AUS/NZ General Discussion
The raptors will have a ball. What happens as regards deliveries to intensive, multi-storey apartment buildings, or multiple strata units on the one property? Sounds like a logistics nightmare to me. Scooter delivery riders have enough problems trying to precisely locate properties now. Ever tried finding someones house number when it's an unknown property to you? Some people won't even put their numbers up. Imagine the number of crims who'll think they're being spied on. BOOM! There goes your delivery! Wing drone delivery WING.COM Wing offers drone delivery.

News media reports are coming in of a light aircraft crash into a paddock on Mulgathing Station (incorrectly reported in some reports as Mulgathy), around 200kms SW of Coober Pedy and 120kms W of the Stuart Hwy. No further information is available until Police and rescue/emergency services reach the scene, which could be close to midday local time, due to the road distances involved. It seems the aircraft involved may be a Station mustering aircraft.

Fuel Filters Hengst H102 WK & H103 WK
onetrack commented on skippydiesel's classified in Aircraft Parts
Skippy, how do these Hengst filters handle water in the fuel? I have never used them, only the plastic Ryco inline, pleated paper style - but the Ryco filters will block up totally with any moderate amount of water, and completely cut off the fuel supply. In an aircraft, I would expect an event like that to be extremely seat puckering. -
Not quite. Personal care soaps contain numerous additional ingredients that are not necessarily beneficial for tyre mounting. Proper tyre mounting paste contains rust inhibitor, and dries somewhat tacky to prevent tyre bead slippage on the rim. In fact, there are plenty of undesirable additives in some personal care soaps that are not even good for your skin, or your health. Do You Know What Goes Into Your Soap? | Here’s Our Top Ingredients to Avoid - Australian Botanical Soap AUSTRALIANBOTANICALSOAP.COM.AU Your health and peace of mind are worth the extra attention when selecting the right soap for your daily routine.

The only thing to use on rubber items for a lubricant is tyre mounting paste. All other petroleum-based products will eventually have a detrimental effect on rubber-containing products - even silicone sprays.

It would have helped to add to the article that the Paramount Group is headquartered in South Africa and the aircraft is a South African initiative.

Lubricating oil is a base crude with a substantial number of chemical additives added to it. All those chemical additives are not stable for the long term, they're designed and formulated to react with undesirable by-products of combustion, deal with major temperature changes, and deal with humidity. In addition, a number of the additives consist of heavier particles, such as graphite and molybdenum disulphide flakes, designed to stay in suspension for some reasonable length of time, but they will eventually sink to the bottom of the oil container after some years. Sealed oil containers usually have a recommended use-by period of 4 to 5 years, according to the oil companies. Once opened, the storage period would be reduced, as the container then has increased air space in it, and introduced contaminants such as moisture, via the air entering the container. Then there's the potential reaction between the oil and the container it's in. I'd imagine oil in metal containers would not be in pristine condition after 5 years, thanks to potential chemical reactions between the metal of the can or its coating, and the oil additives. I'd have to opine plastic or polyethylene containers would pose far less risk of chemical interactions with the oil. But the oil companies play it safe, and they have to cover their a$$$$'s against damage claims, so they set a reasonable time limit on storage, which is likely to be based on the length of time that they consider the additives are still capable of doing their job. There's an interesting and comprehensive article below that discusses oils and their additives. Lubricant and Lubricant Additives | IntechOpen WWW.INTECHOPEN.COM Lubricants have been used by humans for thousands of years in their simple machines such as wheel-axle bearings and sledges. Modern machines are much more complicated and are composed of many...

A big trip and a little rant about airstrip maintenance…
onetrack replied to Philster2001's topic in Trips/Events/Seats
Re the OP's Nullarbor airstrip conditions gripe - one has to keep in mind that the Eastern section of the Nullarbor region in particular has recently endured some of the heaviest rainfall events in recent decades. The Trans Line went under water for 3 weeks, an un-heard of event - and even the Eyre Hwy went under deep water for 4 days, and was closed to all traffic for that length of time. So, it's not surprising that some of the Nullarbor airstrips are in serious need of maintenance and improved drainage. However, I'd expect it's not a major priority when your homestead has been knee-deep in water for a couple of weeks, as in Rawlinna Homestead. Rawlinna Station WA WWW.FACEBOOK.COM Rawlinna Station WA, Rawlinna, Western Australia. 1,366 likes · 46 talking about this · 48 were here. Rawlinna Station, 380ks east of Kalgoorlie, is Australia’s largest operating sheep station. I've just done a road trip recently from Melbourne to the W.A. Wheatbelt in a small truck, and I was stunned at the level of greenery, residual water, and water damage across the Nullarbor, from approximately the Eastern edge of the Plain, right through to Caiguna. I have travelled across the Long Paddock many times since I first traversed it in July 1969, and I have never seen it as green and verdantly lush, as it is now. -

Lugging fuel to your deserted airfield……
onetrack replied to Freizeitpilot's topic in AUS/NZ General Discussion
The simple answer to the OP's question is to develop plenty of aviation/forum mates in many areas, that are mostly happy to assist you with fuel supplies, and transport/resupply of same. I'd be quite happy to assist anyone requiring fuel in a spot where it wasn't available at the airstrip, in any area where I was currently located, and I'm sure many of the forum members would do the same. -
Wanna Fly STOL in Part 103?
onetrack replied to jackc's topic in U.S.A. FAA FAR Part 103 and Basic Flying Machines's Topics
The standard format - glitzy, mind-numbing website, that promises you the world - but never even delivers 5% of what they promise. That's if they stay in business for any longer than 5 years, before disappearing into obscurity. The problem with these companies is they promise you they can deliver on things over which they have zero control - such as local laws and regulations and aviation controls. -
Re the pricing of OEM aviation parts and components - you won't find anything cheap at Supercheap, or Bunnings Aerospace, or any of the tool companies, or big parts suppliers any more, either - ever since they set out on the path a couple of years ago, to ramping up prices to meet the 25%-30% ROI corporate expectations for profit levels. The difference in prices from the original source country (you know, that big Asian supplier to the North of us), and the prices the local rorters ask for these products, is simply breathtaking in the level of markup.

Area-51's nailed it. Importation of mechanical items is a licence for Gubbmint, Border Force, the Dept of Agriculture, and a host of other hangers-on, to bugger you senseless, a-la Lord Flashheart in Blackadder. Note, there is no longer any "Customs & Quarantine" Dept, either - importation controls are handled by such a multude of Gubbmint dark forces, they make a trip to Centrelink to lodge a form seem like a picnic in the park. Then there's the Port hangers-on! My God, the charges and fees and services they can think up, would bring tears of joy to a Russian Border Guard who thrives on bribery. There's security charges, recording fees, container storage fees, container opening fees, brokers fees, transport fees, warehousing fees - oh, and GST on top of everything ..... it's like the scenes from a crashed, and split-open money truck! I'm still smarting in the rear end from several machinery importation exercises, and it's been a number of years since I tried it, and I have no desire to ever experience the process again.

Nev is on the money, listen to him, that's decades of experience talking. Hydrogen embrittlement IS a serious problem if the chrome plater is unaware of the stresses involved in the end use of the product - and it affects high grade steels more than low grade steels. As all aircraft use high grades of steel, it's important to get professional aviation advice on any chrome plating planned for aircraft components. CASA didn't produce the article about the problem just to fill empty pages.

Well done to the blokes driving, they made a successful wheels up landing in the dark, and didn't blow up the airport, which is what the media rabble were hoping to see.

Bit of a shame they didn't hit the actual factory instead of the workers accommodation. I'd really like to see a Russian ammo or drone factory in flames.
