CASA is proposing an amendment to AD/PROP/1 in order to set the maximum time between overhauls for propellers. Basically the proposed amendment to the Directive is to relate overhaul to the manufacturer's recommended flight hourly TBO or calendar TBO.

It is probably a good idea to apply the directive to RAA propellers to maintain good levels of safety.

In the case where there is no calendar TBO, the prop is then use to hourly TBO and at 6 years since new or last overhaul, or since the last Hub/Blade inspection, carry out a Hub/Blade Inspection.

If there is neither recommended flight hourly or calendar TBO, then carry out a Hub/Blade inspection and at 12 years since new, or last overhaul, or last "Bare Blade Inspection", carry out a Bare Blade Inspection.

For wooden or composite props, a visual inspection of the hub and blades for delamination, damage to the leading edges and thrust faces and crushing of the hub by mounting plates. Inspection for thrust bends and angles. Finally, balance in accordance with manufacturer requirements.

That last task will mean that the prop will have to go to a specialist prop shop.

Referring to Australian designs being built under licence in China, has anyone heard how Brumby is getting on doing that? They were going to manufacture their two-seater in China and concentrate on their 4-seater at Cowra. Has anyone go any info about that?

Do you guys know really who invented copper wire?It was two Scotsmen fighting over a penny.

Two Scotsmen? What an insult! Everyone knows it was Jock McRubensteinowitz one his own. Just making a copper stretch further.

Well I'll be blowed! I didn't think that my comment, made half in fun, would ring true with so many people. I hope that it gives food for thought to flying instructors as they grapple with the a student's problem of crossed feet.

We never had a billy cart. Had to slide along on our b$ms. Steered by weight shift.

Oh to be so lucky. I lived at the bottom of mine shaft. Had t'push pit cart t'top o shaft on hand and knee then pull forelock to mine owner to be allowed to fall down shaft steerin' cart with smock like a parachute and usin' our feet on cart wheels for brakes.

You don't see kids racing billycarts much these days. I did when I was a kid. Started off with light weight ones made from fence palings and pram wheels, then as I got older and more skilled in scrounging stuff, I made them out of 3x2 timber and gearbox bearings.

They were lots of fun, but they had an adverse effect on my learning to fly. You see, with a billycart, if you want to go right, you push forward on the left hand side of the front axle cross-bar. Conversely, to go left, you push forward on the right hand side. After years of doing this, when it came to steering an airplane with the rudder, I was arz about. Not a big problem in cruise, but confusing during landings, especially cross-winds.

Did you suffer from the same problem?

OME

I'd say that they'd be as good as any other. Just need to keep them washed. and greased.

Not really wanting to tout for business for anyone, but I had to bring these to your attention. I saw them being used on "Wheeler Dealers" on the Discovery Turbo channel and I thought they were pretty whizzo.

We are lucky that we didn't have to wait for blokes like Lawrence Hargrave, Octave Chanute, Otto Lillienthal, Wilbur and Orville, Glenn Curtis and a host of others to complete their aeronautical engineering degrees.

The airplane involved in the incident with the ferris wheel is probably unique. I've yet to see conclusive proof that it was actually constructed in Morgan's factory. Where is the proof that the fuel line was fitted in that way by Morgan? Fuel filters have to be changed as part of regular maintenance. Who is to say that someone has been lazy when they last changed this one?

Every airplane we operate is built and maintained with a "she'll be right, mate!" attitude. It just depends on the person involved where on the descending scale from 'near perfection' to "how'd you get away with that?" the expression of the attitude falls.

If I remember correctly, the British tried applying the Coanda effect in a 1950's design. I'm sure we mentioned this yonks ago in one of the original Bernoulli -v- Newton threads.

If you have a US registered plane in Australia, you have to get an FAA approved engineer to sign off any work done on it. An Australian LAME won't do for the FAA.

Typical Yankee overkill! Who else would need an eight-man raft in a two-man plane?

OME's Blue Bible of Hardware is a reference book which enables the user to identify hardware used in airplanes by its AN, MS or NAS identifier code so that the user can confidently order the items of hardware required with the confident expectation that the supplier will return the correct items.

It is invaluable if the user is not experienced in using the Imperial measurement system based on the inch as a unit of length.

If you want a copy, PM me with your name and postal address. I'm asking $5 for the CD to cover the costs of the disk and postage.

I also include a copy of AC43.13 1B and 2B plus my tutorial on tying the Modified Seine Knot.

I just called QED Hardware and ordered 1/4 pound of the rivets. Just in case. That should keep me going for a while :)

Hopefully will get them by the weekend.

Rodney should get them into the mail this afternoon and you'll be having a bucking great time this weekend. Don't lose QED's phone number. They are a good source of hardware.

Have you got your copy of OME's Blue Bible of hardware?

With due respect to those who gave their lives, I'm just glad it's over and done with. What's the next 'centenary' are we heading for?

Then we can wait twenty years before starting off again.

I suppose that the Baby Boomer Generation is the first in the history of Mankind that has had such easy access to information about what has gone before it, and what has happened since the generation began. Too bad that such access has not enable to learn that armed conflict is not to source of peaceful co-existence.

Oleg,

Ring QED Hardware on (02) 46551514 and ask Dave Dent to send you MS20470AD4-6 rivets. There are 1,566 of these rivets per pound, or 390 per 1/4 pound. If you only want a handful, he should give you a reasonable price and postage should only be about $1.40.
