  1. Pat, have you bleed the system from the wheel cylinders up using a syringe or pressure bottle? Suck all the fluid out of the reservoir then pump in to the wheel cylinders til no more air bubbles apear in the reservoir. The beringer valve, which I would remove, may have a shuttle valve in it to do what it does so it may have different requirements for bleeding. Need to use the correct fluid as others have said, most aircraft use hydraulic OIL not brake fluid. If the Orings have swollen from incorrect fluid it may be causing the master cylinder to not return fully.
  2. If RAAus cannot help you my guess is there is no pathway. Ultimately CASA is the regulator. To make an engine change on say a Cessna 172 a STC, supplemental type certificate, is required. Perhaps @Rapture can advise you how they are planning to proceed with their Jabiru/zongshen build.
  3. I have never had one, 40 years of very successful two stroke flying now. Hopefully the endorsement instructed pilots to read the engine operation manual, POH etc, no different to any other aircraft or engine system.
  4. Pretty sure Tom's Jabiru is an amateur built 430 with VH-rego so he can do what he likes.
  5. The brake master cylinders at the pedal has to have a spring, usually internal to work correctly. The brake pressure regulator IMHO is an unnecessary part / complication on a simple light aircraft.
  6. You should read the provided link above a few times then you may understand how the whole system works. No individual approved person is going to pass an aircraft that are not airworthy.
  7. This one, formerly VH-PUK had been repowered with a lycoming O-235, 112hp? so should have been a good performer. Ferrying a 1946 Auster J2 through Australia : Air Facts Journal AIRFACTSJOURNAL.COM The aircraft ferry game is both interesting and where one always expects the unexpected. My card reads "Can Ferry, Will Travel." Flying an older aircraft cross country is more than just throwing your bag in...
  8. Lycoming O-235 has the record for longevity I believe for an engine produced in numbers. 1942 to 2025 with almost no change in design or materials. For the Hummel mine would have a 503, best power to weight no question.
  9. In 2019 we flew up the western edge of the lake then followed the Diamentina river to Birdsville in the mighty Musketeer. Was amazing. Going out again in June. Last pic was 3500 agl, would have only just been able to glide to the edge of the river, about 15km wide.
  10. Aircraft looks to be at end of the strip, to much brake?
  11. /graphics/ICAOtype/C172.gif Incident Cessna 172G Skyhawk N3753L, Friday 2 May 2025 ASN.FLIGHTSAFETY.ORG A Cessna 172G Skyhawk, N3753L, suffered a loss of engine power while on approach to Santa Monica Airport. The airplane made a deadstick landing on the grounds of the Riviera Country Club.... Pilot did a great job, Riviera country club doesn't look very aircraft friendly, big holes in the fairways, very high fence in the middle.
  12. I would not call any crankshaft breakage normal. As Paul points out in his vid, the front bearing is very short, the standard prop extension is too long. The crank is not properly supported.
  13. What we need is Avid+, or Avid premium, $20 extra for the extra button press or two on the security computer back ground check. Good for those who only need occasional access to "secure" regional airports, same 5 year duration or make it 10 like a passport, then I think we would all be happy. If I was a journalist there would be many questions.
  14. Weather looking fairly ordinary for Wedderburn over the weekend, fabulous for farming in central nsw, we need it.
  15. The fact that two independent sensors, pressure and flow, show a change at the same time and the change goes away with operation of the boost pump suggests that the problem may be real. How old is the pump in calendar from first use? They are supposed to be changed at 5 years so not a total waste of money to do it now. One thing you could do is remove the inlet fitting and inspect the internal filter screen, see the post above by Underwood.
  16. Normally there is only a bypass on the electric boost pump. I think this is there because an example the facet pump as fitted to my musketeer has a filter in it that is quite fine and could become blocked so an alternative path is provided to maintain fuel flow. The fuel pressure gauge allows us to continually monitor the health of both pumps during pre start (boost) and flying, EDP.
  17. I think we can agree that any fuel pump in a carburetor aircraft will contain two check valves that only allow fuel to flow towards the carburetor. Regardless of the arrangement of the two pumps, in series or parallel, one open check valve in either pump will not cause a loss of fuel flow if the boost pump is on.
  18. One defective open valve in the engine pump cannot cause the electric boost pump to fail as well. Where did the fuel it was pumping go? Pilots should be able to draw a schematic of the complete fuel system in the aircraft they are flying from memory.
  19. My friend and forumite RFguy did his first landing at my farm strip in his excellent Piper Archer yesterday.
  20. Agree, I was wearing a Sony nc headphone, watching a YouTube on the big screen when RFguy landed at the farm recently. Lucky my 6th sense was working.
  21. In your case the boost pump is possibly restoring a smooth fuel flow, masking a fault in the engine pump if that makes sense.
  22. One possible cause, the engine pump has an intermittent fault in the inlet valve. When the valve acts up the pressure naturally drops. The increase in indicated fuel flow is due to fuel pulsing back and forth in the flow meter. If the flow meter is after the engine pump then the outlet valve could do this. Any time the boost pump is turned on in steady cruise flight the fuel flow INDICATION dramatically rises in my RV6a, has to be due to fuel pulsing. Fuel will pulse with a faulty valve.
  23. I met Bryan and had a look through his hangar when I bought a Thruster single from Holbrook in 2021. He was an amazing craftsman, the cars were something else. The ultralight museum, also amazing.
  24. Some motivation for you Danny, you may already watch Mark who fly's his bushcat from tassie to the main land on a regular basis.
