  1. I don't know, there's been more than a few aircraft that have used incorrectly, and went and ploughed up a few paddocks - so I can definitely see the farming and gardening links being quite appropriate.
  2. Richard, the Edit button is on the lower left section of your posting (adjacent to the Quote button), but you only get around 15 mins to edit your posting before the Edit button is removed by default. This is fairly SOP on many forums to keep threads reasonably intact and understandable. The Edit feature is designed to be used primarily, to clarify posts or fix typos or spelling errors. EDIT - Ahh, hang on, I just realised the width description is in the title. I'm not sure if this programme allows title changes by the OP. Usually, only moderators or the webmaster can change the wording in a title.
  3. I watched my SIL's female Blue Heeler fly out of the back of the ute when she (dog) snapped at a passing branch on a bush track, and got too good a bite on it!! She just went - ZIP! - straight out! We were doing about 60kmh at the time, and she hit the track, unhurt - tried to stand up and start running - but she fell over, because her body was still doing 60kmh, and her legs were only doing 20kmh! She did that about 3 times, before she slowed down enough, to be able to get her legs going at the rate her body was going at! Meantimes, we were rolling about in the ute, killing ourselves with laughter. We stopped, and she jumped back in with a sheepish look, and didn't snap at any passing branches again, for a couple of days!
  4. Talking about mine shaft timbers reminds me of the amazing sight that used to greet you if you inspected the "Wealth of Nations" gold mine, 50kms NW of Coolgardie, W.A. The mine workers had utilised local Gimlet hardwood for the props to support the roof - and had installed very sizeable, 75mm thick slices of Salmon Gum slabs, simply sliced off the nearby big Salmon Gum trees, as load-spreading plates, top and bottom of the Gimlet props. But the rock pressure on the props was so great, it had punched the Gimlet uprights clean through the Salmon Gum slabs - leaving the remnant Salmon Gum to hang around the Gimlet uprights, like oversize washers!
  5. Because he's been known to totally destroy anything/anyone, that gets in his firing line??
  6. With a bit of luck, one of the victims carrying a video on the fated flight may have taken some useful footage, that helps investigators pin down the reason/s for the crash.
  7. Brett, what happened to your original AeroVee Turbo? Did it self-destruct? https://www.facebook.com/sonexaircraft/photos/sonex-first-flight-brett-ahearncongratulations-to-brett-ahearn-of-geraldton-west/10154087362063060/
  8. AD/GA8/9 is rather concerning - particularly this bit ... "A manufacturing quality escape has resulted in wing strut fittings in the effective serial number range to be manufactured with incorrect grain orientation. The fatigue implications of the incorrect grain are not well understood. Therefore, CASA has mandated a conservative factored fatigue life limit based on the known fleet data of the affected aircraft. CASA will continue to gather data for the purposes of managing the fleet removal of these fittings from service." One hopes that this particular Swedish GA8 wasn't missed, due to paperwork or communication errors, or language difficulties. https://services.casa.gov.au/airworth/airwd/ADfiles/under/ga8/GA8-009.pdf There are 10 AD's relating to the GA8, and one is related to wing strut fittings, and one is related to HS inspection for cracking and improper assembly of fasteners. https://services.casa.gov.au/airworth/airwd/schedules/ad_display.asp?sched=under&toc=ga8 The destruction of SE-MES is very extensive, the fuselage broke in half at the cargo door, and the rear section is missing all its tail structures. The photo below shows the rear fuselage section lying in the forest, obviously some distance from the rest of the wreckage, thus indicating the fuselage broke apart in the air. https://www.abc.net.au/news/2019-07-20/plane-crash-near-umea,-sweden-1/11328534 SE-MES in better days. https://www.flickr.com/photos/[email protected]/27343742728
  9. There's some information on recording conversations in the lawyers website link below ... https://www.mst.com.au/legality-of-secretly-recording-conversations-in-australia/ The legislation varies from State to State - but the over-riding principle is whether the conversation is private or public. A conversation on aircraft radios cannot be considered private, it is a public conversation, so no problems as regards recording it. The principle is the same as videoing/photographing people who are unaware that they are being photographed. You do not need peoples approval or agreement to video/photograph them, in public areas, because they are in a public place. But if you video/photograph someone who reasonably believes they are in a private place (with a reasonable expectation of privacy) - such as their bedroom, or even a fenced backyard, you can then be found guilty of a illegal recording crime. There is also an allowable definition of "commercial interests" attached to recording of conversations. This means that a recording can be made if one party has a commercial interest in the discussion. http://www.mcleods.com.au/news/local-government-updates/recording-conversations-without-consent
  10. Every "new" war is a vastly different war from the previous one - and each "new" war is a massive learning and development curve, to counter the "new" systems the enemy has devised. In the next war, F-35's won't even get off the ground. Drones will be the way the war is carried out, armoured war robots will be everywhere, and more war action will be carried out at computers based in hardened bunkers, than ever will be carried out by ordinary soldiers on the ground, or in the air, by manned aircraft. The greatest threat to participants in the next war, is who will have the technology to unleash massive EMF bursts to destroy electric power facilities, and who will have the ability to destroy GPS satellites in space, thus "blinding" the enemy.
  11. The history of mankind on this planet is one of continuing, and continuous, killing and war. There's a reason this planet is out on its own in the Universe, and we cannot find any similar life within reach of us. It's simply because this planet and its inhabitants, is the Alcatraz of the Universe - the dumping ground for every type of scumbag that was ever brought to life - and no other life form in the Universe wants anything to do with us, in case we transfer our constantly murderous, war-mongering behaviour, to their peaceful planets. If we do happen to eventually colonise any close planets, it would only be a matter of time before murders took place there, and a war was started there. Sorry if my opinion is too negative for you, but I fail to see any likelihood of murderous behaviour and war-mongering, ever ceasing on this planet.
  12. Bilguun, do you have access to the Heavy Maintenance Manual for the Rotax 914? Here is the link to the HMM. https://m.cps-parts.com/cps/pdf/d05014.pdf Your 914 turbocharger and wastegate is controlled by an electronic regulator (sometimes called a CPU - Central Processing Unit, other times called an ECU - Electronic Control Unit). Rotax call the 914 electronic regulator, a TCU (Turbocharger Control Unit). The TCU takes information from several sensors located around the engine, and processes this information to control the turbocharger and the wastegate. The initial requirement is to ensure the throttle is positioned correctly, and the wastegate control mechanism is similarly correctly positioned. Section 76-00-00 of the HMM gives all the information you require. If the Throttle Position Sensor is feeding incorrect information to the TCU, there will possibly be a lack of power. Note that because the TCU is an electronic controller, it logs faults, as well as many other engine parameters. This information can be extracted from the TCU by the use of a computer and the necessary TCU interface, which is proprietary Rotax software (that is, you cannot use any other software or program). This interface is called the "communication program" by Rotax. It comprises software, and also a dongle for some models of the TCU. Section 76-00-00 outlines what is required (pages 13 and 14). I'd suggest you check the TCU log via the Rotax interface, on a computer, and see if the TCU has logged any engine faults associated with the turbocharger and wastegate, and any other engine controls or sensors.
  13. What's a nanotrike?? A trike you can fit 3000 of, on a pinhead??
