What specific info does Ra Aus need for propellers?

[danny_galaga]

I'm nearly at the end of my paperwork. But also at the end of my tether. I've supplied an invoice for my prop, but because they haven't heard of that brand need more info. This is the manufacturer:

 

http://www.p-propeller.co.za/

 

My invoice has a serial number and prop size. Makes me laugh about the thread for making your own propeller since it seems it's not legit if ra Aus have never heard of it 🙄

 

I've half a mind to sell my prop as a decoration and buy a Sensenich. Wonder if ra Aus are familiar with that little cottage business...

[Thruster88]

Yeah but the Sensenich may not be approved for your aircraft, then you will need a marup and  another $600. 🤨 I miss the good old days.

[danny_galaga]

Kit plane.. doesn't come with an engine or propeller. Surely whatever you fit, it is the correct propeller?

If it gives the required thrust and doesn't over rev the engine and It's wood. you should be good..   Nev

Did you advise them its owner build not a factory build?

You would think so. Fingers crossed. I'll get more info from the manufacturer, including his star sign and favourite beer.

Agree with the inference made by Blue.

 

As the builder, you can put a V8 & a  dometic fan blade on the front if you wish - it may not pass its safety inspection or get off the ground but those are two other matters/hurdles.

 

People have crafted their own prop - how did they manage to be aproned????😈

Looks like a good place to get one. RAAus is not supposed to be more strict than CASA would. You'd probably be OK if you had a DH 82 on VH . Silly.  Nev

As you would know, the DH 82 tiger has to be fitted with the correct propeller or get an engineer order to fit something different. Nowadays RAAus is no different. Same same just different words.

i think you will find that has changed now.  everything has got harder the last 12 months  with raas.  the mt beaty court case has ruffled a lot of feathers.

i have registered 2 19 category planes recently and i had to supply information on engine and prop. 

had a hell of a time getting a 582 powered xair transferred because it had a sweetapple fitted but had a brolga when first registered. they accepted it eventually but it took 2 weeks.

You'll notice on their website that P Prop have in fact supplied props for Tiger Moths ☺️

The engineering order for the tiger probably cost as much as the prop, that is what people get miffed about.

[facthunter]

It's BS anyhow. Wood laminated and done properly have no bad surprises and are easy on the motor. In theory I could design and build a complete motor for the right category.   Nev

May be.

 

When I  registered my 19,  late 2022, Aircraft varies significantly from factory plans. I supplied everything asked for, which included prop make/model, instrument calibration/certification, independent inspection/comments, W&B, test performance data and Max TO weight, etc, etc.  I used the factory recommended Max TO Wt. Found out later, as builder, I could have nominated whatever Wt I chose. Contacted factory requesting approval for one off higher TO Wt, with reasoning- flat refusal. Months later factory upped Max TO Wt (to meet new US guidelines for class of aircraft) with no structural changes. Applied to RAA for Wt increase - told my prerogative as builder - send in photo of revised panel placard - done & approved. So much for all that BS about home builder having to stick rigidly to factory plans/specs. 😈

At the end of the day there has to be SOME form of oversight as always its for the Lowest performing cowboys or whatever  that ruins it for everyone.. People are fundamentally lazy and cut corners when not watched. She'll be right Mate, is alive and well.  That's OK if it only affects YOU. but it's not like that.   It's a culture , safety and IF the show doesn't have it you will eventually "draw the Crabs". Nev

[danny_galaga]

Agree on the oversight. But verifying the veracity of my propeller is one google search away...

[facthunter]

Google has veracity? IF only it were so.. Fools abound  and they are good at it.. Beware of them. They cause all of us, Grief.  Nev

[danny_galaga]

Um, what I mean is if someone is wondering about the veracity of my propeller, they need only type the brand into Google and find the website

I guess so. I live in the world that if I want to find something out about a manufacturer, I can type their info into Google and find their webpage, and find something out about that manufacturer 🤷‍♂️

[onetrack]

You just have to be careful about what Google throws up for search results. Scammers set up fake websites to scam people, and then "game" Google search algorithms to end up high in Google search results.

A recent example is the legit-looking site recently exposed, that claimed to provide heaps of great information about upcoming welfare payments. But the payments are non-existent. However, the information provided is about legit earlier welfare payments - the scammers just make it appear the payments are going to be repeated.

I think I'm reasonably savvy, but the fake "information" site took me in. However, after close reading of the "information", it became obvious to me there was something about it that didn't jell. The style of writing was poor.

I suspected it was written by AI, but I didn't realise scammers do this setting up of "information" sites regularly, to set up unsuspecting people up, same as any other sting.

 

Incidentally, if you come across a fake website (there's plenty out there, watch out for the ones selling bargain aircraft parts!), you can report them to Google, and Google will delete them from search results.

Of course, this doesn't stop the scammers from just changing something about the fake site, and then getting back into Google search results again, though. It's a "whack a mole" game, just like trying to block scam phone calls.

That was 2022. Ths year things have changed. Raas are going over everything with a fine tooth comb these days.   There are inconsistencies too. Forcing people to get casa weight and balance checks at a cost of up to $1000 . My 2 xairs they dropped one to 450.kg from 544 and the other to 490 because I said I wasn't happy with 450.  There is a bloke on Facebook who was made to get a w&b for a trike at a cost of $835, it was a standard Aus brand trike with no mods at all, been regoed with safa for 20 yrs but raaus forced the issue as part of the transfer. A vh plane can go it's whole life without a w&b if it's not modified.

Why. All the main manufacturers have a website with all the information you need..  it's 2024 nev not 1955

That's because the manufacturer has provided a certified dry W&B for the aircraft to FAA/CASA etc.

From that comes the envelope version of the same set of equations.

 

Qualified Engineers need to be paid. The going rate for a minor wheelbase change certification for a truck is currently around $1100.00

The Max TO weight increase, was just a month or so ago.

 

I can't comment on why RAA would impose changes to existing TO wt.

 

As for Certified W&B. It would seem that RAA had its authority, to approve W&B, removed for some reason. This meant that anyone requiring a W&B, had to go the CASA/Certified rout, including me. I shopped around and found a Certified service provider, at a considerably better price (almost 1/2) than what you have quoted.
