Old Koreelah

...there are more bits that fail from infant mortality than old age...

Sounds like the concept of Reliability-Centred Maintenance, which seems to be based on the finding that most failures happen immediately after an aircraft has undergone maintenance.

Jabirus have Bing pressure compensating carburettors.

Yes KG, but do they have the same float problems?

Good info, Mike. This issue was the focus of discussion a few years back, with regard to Rotax carbs.

Although Jabiru's have the same unit, I haven't heard any mention of float problems with them. Have you?

The beautiful C-46. There are a couple still flying in Northern Canada.

I think , if I had a Jab motor I'd seriously consider doing the" near the prop" starter drive conversion...

Is a kit available? Sounds like major surgery.

It might be easier to mount the prop outboard of the flywheel and turn the whole plurry thing backwards, as some did to their VW engines.

Welcome back, RV; where's ya bin?

...I'd be a little concerned with having a battery that spins the engine a lot faster with the flywheel bolts and all that. Nev

Nev I agree, and I've raised that concern before; It only seems to be an issue when restarting a hot engine.

When starting from cold, even on hot summer days, my LiFePO4 battery starts slowly, as if nearly flat, then quickly builds up revs.

...I will have to put 8kg in the tail, yikes! So it will need the battery moved back to the rear curtain area to reduce this number...

Crikey that's a lot of weight!

Is it possible to relocate your tie-downs, toolkit etc way back in the fuselage?

Bruce I presume such a major change of battery type would contravene a Type Certificate.

Then the major issue is the change in CoG.

I'm having a bit of difficulty sourcing a replacement battery for a Jabiru...

 

Can anyone suggest a compatible battery?

If you're 19- reg you may be able to fit a lithium. Lots of us have had good service from drop-in LiFEPO4 batteries, which are mobs safer than other Li types, keep their charge for months and are said to last ten years.

The huge reduction in weight is a bonus, but only if you can rearrange other items, such as the tool kit, to preserve CoG.

Poteroo when reading stories like this I often look up the places on Google Earth; Naoro seems to be overgrown, but I looked up the other strips.

I dips me lid.

Thank goodness we live in Australia

It's early days, but their seems to be big variations in infection and death rates across the world.

America is being hammered more than most by this pandemic. I suspect a few questions will be asked about their woeful unpreparedness and the disorganised response by many authorities.

...Trump has thousands of documented lies to his credit based on reliable sources....

Over ten thousand, but who cares? His supporters don't.

I hadn’t realised Warren were a member of this forum..?.

I presume you are referring to Elizabeth Warren, a well-respected and articulate politican, unlike the crackpot who abuses her with such terms as you have used.

Since she is a single person, I'd suggest was is the correct word to use.

Seems even a Democrat can come up with an intelligent idea occasionally....?

 

... ding-bat warren...

FB if you are trying to convert people to your way of thinking, then I suggest a more respectful tone is required. Insults like those you have used are the stock-in-trade of low-intellect conmen with nothing to offer but division and hate.

I would commend to you the excellent video in Post #436 above; that scientist speaks thoughtfully, carefully and with enormous authority. He doesn't insult people, he doesn't criticise the dumb leadership he has had to battle with. He gets his point across with clarity and respect.

If, on the other hand, you are just letting off steam, then I've tolerated your rants for long enough.[/TD]

Just in case restrictions on flying cause this thread to wither; this morning I returned to the airport to look for an expensive torch I'd lost last time I was there. I'd needed it because of a very early start- that was the day I brought my plane home. After loading it on the carrier I spent an hour walking the grounds spraying weeds.

I'd put the torch in the long leg pocket for my work trousers, which rotates beyond horizontal when you sit on the mower. An hour of bumping over rough ground had dislodged it. I expected to have to search acres of grass, so had brought along my other half to help; she had been cooped up too long and (for the first time ever) was glad to drive to the airport.

Searching methodically, I began in our fuel shed, where the mower lives. With another strong torch I searched the whole machine and bingo! There it was resting precariously on the cutting deck. A good start to the day.

There are several threads on here about Jabiru engines. Some people have had issues with theirs, but I'm very happy with mine as are lots of other owners. Interestingly, Jabiru engines seem to have a much better reputation in North America, Britain and Europe.

I believe there are more Jabs flying in South Africa than Cessnas.

Lots of discussion on here: [email protected]

You expressed interest in buying a Jabiru aircraft. There are lots of good ones for sale, but get some advice from reputable people. The Jabiru airframe is one of the safest, both because it has been tested more than most and because if pranged, people are more likely to survive. Also the airframe is more easily repaired than most.

...If you were to have an accident you could be infected by first responders coming to help you, or worse, no one being available. RFDS were operating at full capacity about a week ago and we are not in the peak yet...

Our VRA unit has been called to more road accidents since the shutdown started; strange because traffic is greatly reduced. Our numbers have also been hammered. For Monday's callout only three of us were available.

Sad day. This morning I drove to the airport and brought my little plane home for long-term storage.

Each time I do this, the steel bores need to be oiled to postpone corrosion as long a possible.

That operation requires the engine to be warmed thoroughly. To do this without overheating the heads, lots of airflow is required. That means taxi runs at 2000rpm up and down the airstrip; if full flaps are deployed it might lift off and skim the strip just above stall speed...

...The trick was to 'make fuel' as 'Facthunter' would know.

I'm intrigued, Machtuk. Is this some trick kept secret by heavy metal drivers?

...The $500 is a great idea. It’d be interesting to play find the Old Koreelah story...

Go ahead, Mike. I bet you can't find it among the plethora of stories.

...

I’ll hope to never add a story. I have my own story but it’s not worth writing up. Just a problem of anatomy leading to control surface problems. More simply... my stupid big feet and long legs meant over a long cross country my feet were riding up rudder pedals and I took off and landed a few times with really bad rudder control...

You're not Robinson Crusoe! I've had lots of similar problems. My long frame doesn't fit into quite a few aircraft that I'd like to fly. One that I squeezed into had crappy plastic seats, leading to a pinched nerve before I even got airbourne. Lots of fun landing a Thruster with no feeling in your feet!

...The foreign students are a worry at times, with unintelligible calls and questionable circuit procedure's. On the other hand they are learning a new complex career in a foreign country with a second language, must be very difficult so I try to cut them some slack. I do blame some of their instructors for bad habits. They always join "Midfield crosswind" no matter where they are in the the circuit or inbound...

All true, SP.

We had BAE use our strip for years, and their foreign students helped keep our little airport viable.

Now we have CAE, which currently trains 80-odd Chinese pilots. They occasionally drop in and are good embassadores, but they can be hard to understand on the radio.

...If there’s one thing I’m sure of it’s this..... Shared experience of both aircraft and pilot problems leads to safer flying...

 

What I’m puzzled about is seeing reluctance here to share the gritty information. The “oh, I buggered that up” as relates to flying and aircraft...

Good points, Mike. You're right that some who post on here have copped a bit of flack, but mostly if they hadn't seemed to recognise the error of their ways.

In Australia we love to criticise the authorities -it's almost a requirement for getting citizenship- and CASA gets plenty.

However, in defence of our aviation regulator, they also encourage pilots to be candid about their mistakes, so that others can learn the lesson. They even pay you $500 to tell the story of how you stuffed up.

I wrote one these stories:
