    I guess it is a momentary switch. You buy these as normally open or normally closed. I'm not sure if it can be changed.

    Turning the engine over by hand probably won't "pop" the ball as you need to reach the pressure it is set at for it to lift.

    If those that DID NOT vote paid higher membership fees perhaps they would vote then..... And perhaps those owning an aircraft should have 2 votes......(they have paid 2 types of fees)

    Theory two..... Does the oil filter have a bypass valve? Maybe this stuck closed......

    If I was building a strip, researching prevailing winds would be important. As well as determining the length required for the type of aircraft I wanted to land there. It's no good building a "convenient" strip which is unusable.

    I asked around if people were voting in the RAA elections. Mostly people simply couldn't be bothered. Didn't care. Some thought I was the wierd one by actually taking an interest and voting. I can't help thinking most Australians are actually very ignorant and naive about political processes and the ability to initiate change. Basically sheep, waiting to be told what to do......

    If you were going that far, you might as well upgrade to a Keller, which would mean a new gauge and wiring..... Mine has lasted well and I've not heard of problems......

    Different countries have different discrimination laws...... obviously. They might save $500 000 in fuel but in Aus they'd be PAYING $500 000 in law suits... I've seen a few "chubby" flight attendants in the terminals in the last few weeks. A reflection of our society in general unfortunately.

    One theory..... The oil pressure control valve (ball and spring?) May have had the ball stuck for a few seconds overpressurising the system for a second or two. The seal on the oil filter may have been the first point of failure and popped out briefly. Cold oil (higher pressure) and sitting for a while may have contributed to this. Perhaps some oil residue of some sort sitting around the ball. Do you turn over, mags off, to get oil pressure first or a straight kick in the guts?

    Put ozrunways on your wifes phone. It will cost you nothing to put it on an extra device. Who knows, she may enjoy looking at the airports and destinations.

    Does your harness fit alright with that on?

    The safety advisor that does mine seems to know very little about "recreational" aviation, GA or otherwise, and tends to engage more with the commercial operators in the room. Yet the theme of most nights is directed more at private operations I feel, with the majority attending from that demographic. Many of the local commercial operators never attend which seems strange to me as aviation is their livelihood......

    Runway direction. Short and into the prevailing wind, or long and with a cross wind. Is this what we are talking about?

    I have heard (second hand) that the power company in WA may supply them free and fit them when a service crew is in the area. Not sure about your state but worth a try?

    You only know the actions you've taken to get you home were successful and safe, AFTER you get home successfully and safe..... Until you get there, the dice is still rolling....

    At 12 to 16000 ft OAT is going to be pretty cold but the turbo is going to be working hard compressing air to sea level oxygen levels so I don't really know if this temp is normal or not. You will get the best answer from the "Rotax Owners" forum. There are a number of sensors on these engines to control boost limits. I imagine air inlet temp is one of them.

    The aircraft at Whitegum was "Viv's" (Vivian?). It is an FK aircraft. Nice bloke and would be happy to talk to you I think. Contact the SABC. https://www.sabc.org.au/ Or attend the fly in, this 27th October. From what I know it runs fine but the engine (and conversion) was out of production some time ago so parts are not as common and you usually need to import from europe. If l was looking for a new engine, Aeromomentum as above would be my number 1.

    Depends on how far off the firewall the back of the engine is and what is in the way. Plenty can be accessed and done in place. It might also depend on the ...ahhh... "flexability" (physical and mental) of the person involved replacing it. The longer it takes, the more $$ can be charged. To be CLEAR, I'm not making and accusations against an individual or organisation and have no knowledge of this particular case. Some do indeed require engine removal. Most leaks I have seen have come from the threaded section of pipe elbow that goes into and out of the heads. These just have loctite to seal and hold them at the correct angle for the hose, so try not to knock or push on them. As the loctite sets hard any movement "cracks" the seal. They generally just start a slow weep picked up on inspection.

    The information I have is that RAA aircraft should run on hobbs and GA on tacho. That not particularly being my opinion, good or bad, but from what I've seen. There was a local aircraft that was changed from ga to RAA rego. It was maintained by a LAME under tacho hours in GA. RAA wanted it maintained under hobbs, so it "gained" a couple of hundred hours unfortunately. Note, it contained both hobbs and tacho meters. If it was me, I would have probably just continued on tacho, and not sought clarification....?

    One of the major issues is springing an oil leak and covering the windscreen, obscuring visibility. Pushers obviously have no problem with this. Probably with a fire, you don't want it coming out the top a also.
  21. Downunder
    There is no match up or cross reference between pilot hours and aircraft hours in the RAA system.
  22. Downunder
    If an instructor and student are flying, is the RAA counting both?
  23. Downunder
    Yes Bruce, most definately. The oil is however, basically sucked through the cooler from the oil tank. Then from the pump directly into the engine galleries. Like a few things on the Rotax, not your standard setup.

    One of the major (external) changes between the Foxbat and Vixen is the flying tail in the Vixen. Combined with an overall more aerodynamic fuse, 10% improvement for the tail seems about right.

    Yes....first time! Rosebery....arrived Devonport today on Qantas. All free for work... Last Monday I was at Mt Augustus....middle of WA.(on my own dollar) Bit of a difference...
