    Humans are intelligent and ingenious, all the possible internal combustion configurations have been thought of. The 4 stroke piston engine will not be dethroned by any other ic engine. We had a GM 8v71 at the old farm, just because it was a cheap option to re power an old earth mover. Ultimately the market removed that engine from use in new equipment.

    No they are single flare. There is a backing part that is inside the nut. The nut should turn on that piece so the pipe flare is just being clamped.

    Every Cessna, Piper and Beechcraft has it in their fuel system. There is also one aluminium flared pipe attached to each cylinder head on every Lycoming engines as the oil return line, doesn't get much harsher in terms of vibration. They have been doing this for at least 60 years now.

    250k over 1200 = 1 in 208 before insurance co profit. Is your chance of death while flying really that high per year? My rough analysis suggests it is closer to 1 in 2000 (for active RAAus pilots), still alarmingly high. If you have aviation disease, and it seems like you might, you will not give up flying. Can't get insurance so what to do. The only way forward is to manage your own risk. I have studied light GA aircraft accidents long before I learned to fly 38 years ago age 21. If you avoid the big three, stalling in any phase of flight including after engine failure, VFR in to IMC, ie flying in cloud while not rated for it and low level beat up you will improve your risk of not dying in an aircraft accident to very near 100%. Treat each flight as a mission and plan accordingly. Think what is going to happen in the next five minutes of this flight as you fly.

    From the news video and incident report it sounds like a messed up go round, aerodynamic stall, wing drop, cart wheel. Stalling, from any height, is and always has been the number one way light aircraft crash. How do we fix this? Airline pilots never stall their aircraft, should us simple flyers try to emulate them? No disrespect is intended to any pilot. 3/5/2023 Armidale Airport NSW Morgan Aeroworks Cougar Viking Aircraft HF-110 STATUS: Under review OCCURRENCE DETAILS SUBMITTED TO RAAUS: During landing there was a gust of wi... STATUS: Under review OCCURRENCE DETAILS SUBMITTED TO RAAUS: During landing there was a gust of wind. Aircraft powered up and subsequently impacted terrain.

    If you have a rough diagram of what are need i am sure Rodney or any other LAME would help you. They may even have all the fittings in their store. I am curious why you need to modify the fuel system, is it in accordance with the sonex build manual? Have you obtained advice on any modification None of the fittings (nipples, elbows or crosses) come with nuts because they are usually part of hose assembly.

    I think Skippy used the term "calibrated airspeed" to mean the box connected to the aircraft pitot tube was calibrated, not CAS you find in a POH.

    After 8 hours straight and level flying in RFguy's excellent Archer I had to get in the thruster and wind back up with some manoeuvring around the low cloud during the Saturday rain. Always love checking the farm after rain.

    Hello David, we flew over your place on Thursday @7500, the Nyngan Tottenham area was looking very dry so glad you got some rain. Think I saw you dry sowing NE of your house. 50mm for the weekend down here in God's country. How is your Thruster going, will have to catch up after sowing.

    So, what are you going to build?

    Four Luscombe 8's very nice.

    A tip for next time is to use labelled zip lock plastic bags at each stage of any disassembly. Much harder to loose things that way.
  13. Thruster88
    I think there are two at Forbes NSW, used as tugs.

    If that was the DA-42 Diamond there is more to the story. The Pilot Operating Handbook has specific instructions in regards starting the aircraft with external power. Only one engine may be started with external power and the second engine is then started using internal battery once it has charged up some. That did not happen in the accident aircraft. The Rotax 912is, 915is engines have proven themselves. Once again pilots need to understand the systems and heed the warnings of faults in the redundant systems.

    Looks like they had the door cracked open prior to touchdown, text book perfect.

    Reading the rotax manuals it is pretty clear, the engines cannot be operated over TBO hours or calendar. Rotax also say only rotax authorized service centres can overhaul the engines. This applies to 582 and the 9 series. Rotax also say individual regulators can apply more stringent requirements.

    Kevins figures above were in response to my thoughts of a jabiru premium model using a Rotax 916. The mid spec jabiru 230 is $164600 add $9000 for adsb transponder and $9500 for the autopilot = $183100. If we take off 20K for the gen4 and add 70k (I am sure they would get oem price) we have our premium jabiru 230 for $233100. Not a lot of money today for a very good aircraft with a very good engine. Only a 915 would be be required for our premium model as we are not chasing takeoff performance just cruise at altitude. Sling and others are showing what can be done with these engines.

    Would love to see this engine in a premium jabiru factory aircraft. At 60-80k over the standard 120hp model I think they would sell very well to buyers who are not going to consider the current product. A mini cirrus at a bargain price.

    An interesting story and it may help the film launch. The pilot in me is a bit sceptical, is the trim on a light two seat sportstar really that powerful it would cause you to lose control at um the exact location your nephew is filming.

    If it was only upto RAA we would have had group G some time ago.
  21. Thruster88
    That could be the case. We already know group G will require LAME maintenance. Only the medical remains a mystery.

    Thread pitch on those Jabiru head bolts 1.25mm? So 30° turn = 0.104mm of head recession . Doesn't sound like much unless it is happening every 25-50 hours.

    My experience has always been the DAME submits the paper work, or nowadays, email to CASA. If the DAME has issued a medical it is available immediately to print and put in license book. If the DAME has submitted the medical for review then it will not be valid until review is completed. Not sure how GP basic med works.

    CASA schedule 5, the most common system of maintenance for light general aviation says something like, inspect the fuel lines, vents and drains of the fuel system. The drains do not have a life that I am aware of.
  25. Thruster88
    There is always the possibility of a fuel leak. Cap left off in the dark, leaking drain, cracked fuel line etc. Forced landing due to leaking fuel drain In a twin such a problem would be isolated to one side, left fuel tanks feed left engine unless cross feed is selected.
