This inspection requires specialized tools. No service station in the US has them right now. They will likely have them after 1st of the new year.

My local Rotax service guy - told me of this ...dropping the SB before Christmas - prior to their European extended work-vacation ...going to have a lot of rotax "I"series powered aircraft grounded for some time ...at least less attractive flying weather in NthHemi. winter!

Well it isn't an Alert Service Bulletin (ASB) which would ground someone. It is mandatory to be done within next 25 hours or within 1 year. So you can schedule it for next time but not necessarily grounded.

This is a ‘Mandatory’ SB but not an ‘Alert’ which means an obligation to execute no later than 25 hours after being informed of it.
What can happen - loss of power on one generator, you still have a backup generator, if the other one fails as well, which is a very exceptional situation then you can still continue the flight until the battery runs out of power after switching Battery Backup.

Kris, are any of your sold units in those SN batches? Anybody burn up a stator?
Does your company, after sale, send notices to customers or do you leave those issues to each private owner?

 

[Abid]

Also if you read the SB it states that if you have over 200 hours and haven’t had stator fail then this SB does not apply to your engine.

You are supposed to have a flow meter and actually get the reading on it to be more than a certain amount with compressed regulated air, aren’t you?

 

[ARGON Producer]

You are supposed to have a flow meter and actually get the reading on it to be more than a certain amount with compressed regulated air, aren’t you?

All you need is a hand pump that produces over and under pressure to check that the oil spray nozzle is unobstructed.

The problem lies in sloppy nozzle installation by the factory and possible sealing of the nozzle hole by anaerobic glue.

In our company two engine from seven was affected.

That is the way I read the instructions.

I guess what I was asking and not making clear is: Do customers have to look for info or do they get sent the info because they are on your list? Like the NTSB "Safety Recall" on USA automobiles that the selling dealer sends to the customer in the mail.

That is correct about nozzle installation and blockage, but the flow measurement tells you if the nozzle is partially blocked or not because that still needs correction and that is the way Rotax wants us to comply with the SB.

Step 4:
Attach a pressure regulator (1), shutoff valve (2) and a flow meter (4 or 5) to the measurement
adapter tool.
NOTE: For measurement a flow meter is required, either a digital or analog one;
if using an analog type, this one needs to be in vertical position while the
measurement is done, otherwise the measurement will be inaccurate.


And then there is the special "test tool oil spray nozzle assy" #976740
Maybe a 3D print file available soon.....

But all these are EXPERIMENTAL, so nothing really needs to be done at all, right?

Of course for Experimental nothing needs to be done but it would be foolish.
Rotax service centers are going to have these tools available early next year I believe.

Interesting. For our safety we are grounded (yes, 25hrs) till they let us get a tool.

There is no need to wait for “magic tools” the nozzle that splashes oil on the stator must be unobstructed. Why it may not be unobstructed - well, some of the assemblers at the factory carelessly applied sealant, which could seal the splash nozzle - the hole. Checking whether the nozzle is unobstructed can be done with a tool for millions of coins or with a hand pump that we show in the video.

Besides, this is not an ALARM bulletin, grounding the ships was an exaggerated procedure, ROTAX described it as to be done no later than after 25 hours or at the time of annual inspection.

They have updated and made an Alert Service Bulletin asking everyone to check that backup battery system in the aircraft functions during pre takeoff checks till this inspection is completed.

You may be ok to just test with a hand pump without checking flow rate but if one of customers does it your way and nozzle is partially blocked and then their stator goes out in 100 hours, you going to cover the cost because Rotax certainly won’t if you don’t follow their directions and log it that way.
I am surprised as an oem you have put this out on the web in writing.

Authorized distributor of ROTAX in Poland company FASTON made a test of 7 engines in my factory, one of them was recorded in this video we published.

I guess this explains everything
