Jabiru7252

Ah yes, the healthy channeling of aggressive instincts into acts of senseless violence. Love it.

Some dozy cow ran to the crash with her little kid in tow!!!!!!!!!!!!!

I suspect that 'unable to start the engine' is more a result of not knowing how to start a Jabiru. Using the choke correctly is most important and perhaps students are not being taught the correct procedure? It's in the manual. Cold mornings are the worst. If the battery cannot crank the engine at 300RPM or better it won't fire. If the battery used by Jab was not up to the task they would have picked up on that long ago.

some light reading while waiting for the kettle to boil.... https://dnrme.qld.gov.au/business/mining/safety-and-health/alerts-and-bulletins/mines-safety/exploding-lead-acid-batteries

The charger has been tested as working okay since the fire. We will never really know the cause. By the way, if you look at the wiring diagram for the Jab, JTM001-8, page 268 of 301 you will see an error. A relay is permanently wired across the battery!!! Jabiru have confirmed this is a mistake and the connection should be on the bus side of the switch.

Spacesailor - I'm having trouble working out what your last post means. (And I've only had two ports so far!)

I own my hangar.

My plane costs me about $50 a week just sitting in the hangar. That's insurance, hangar costs, rego, licence etc. But, I can afford it because I bought my plane in my mid fifties when all other things were behind me.

I still think 90% of hacking is from the inside.

The battery chargers are used to keep the battery topped up, although with all the flying the planes do, it does seem a bit pointless. As for the battery removal, it's a pain to get the battery in and out of a Jabiru.

Standard Jab battery I believe, Odyssey sealed lead acid, probably PC625 or similar.

Destruction was such that I doubt anybody will find out what happened. If a rat chewed the wires, it would have been in the last 24 hours and as far as I know the hangar, being used so much has no rodent problems.

A Jabiru, parked in a hangar, master switch off, battery hooked up to a smart charger. Without warning the aircraft catches fire and is totally destroyed. All aircraft are checked at the end of the flying day to be sure they are stowed properly. This aircraft had not flown for a few days. A look at the wiring diagram shows that the battery is pretty much isolated from the aircraft when the master switch is off. No fuel leaks around the plane. So, I'm suspecting either the battery caught alight (standard Jabiru battery fitted) because it was faulty or perhaps the smart charger cooked the battery. I would think being 'smart' that would not happen. Your thoughts....

I don't need to show off, I have a pilot licence.

Interesting comments. In my Jabiru J170, when I pull the throttle back, I have to hold the nose up to wash off speed. They are 'slippery'.

I need to get out more, I have no idea what IR and IREX means. (IR means Infrared in my line of work)

I'd say he stalled because his angle of bank was way too steep for his speed. Pretty simple in my book.

Oh well, at least he didn't kill anyone on the ground.

78 years old! I'll be happy if I can make a coffee at 78. RIP.

Steam trains carried a few tons of coal to burn and a few zillion gallons of water. It's no wonder it never made it into anything else, apart from ships and factories.

Armature built? :lightning:Welcome to the mob...

You only ground one end so you don't get currents flowing through the shield. That can cause problems itself.

When I was in about grade 5 or 6 I remember how a teacher said that hydro-electricity was where water was turned into electricity. I thought that was amazing and desperately wanted to know how it was done. When I discovered what really went on, I was quite disappointed.

What gets up my nose is that an aircraft transceiver is just a simple AM transceiver, like the old AM CB radios, just using VHF instead of HF. Now, if we have to pay $1000 for a simple piece of kit then I would assume that's because they are built to a far better standard than a CB radio. So, how would MicroAir be allowed to produce rubbish? There is nothing that justifies the ridiculous price for any equipment we put in planes. I know folks who still have working AM CB radios from the 70s.

The last time I looked inside a modern radio, I could identify the audio chip (LM386 I think) and a few components. All the rest has shrunk, never to be seen by old eyes again. Been out of the radio servicing game for thirty years after taking up digital electronics and programming. My retirement plan is chemical engineering, I intend converting port, wine and beer into urine, probably on a daily basis. Perhaps the suspect radio should be placed on a vibration table while testing its performance. My Microair has been faultless since 2009.
