That's true, but the link was sent to me from the Feds, and the title on the link said "general aviation". Typical Fed way of paper tracking.

MT Governor failure

FWIW, my narrow deck engine has 9.0:1 compression and dual Slick impulse mags. Obviously nothing in SB#27 wrt the bushing issue.

Not unusual for the feds. From the IA test guide:
Malfunction or Defect Reports
All malfunctions or defects that come to the attention of the holder of an IA should be reported on FAA Form 8010-4. (Refer to appendix 1, figure 7.) Copies of the self-addressed form are available at all Flight Standards District Offices (FSDOs), easy to fill out and require no postage. Prompt reporting will contribute much toward improving air safety by helping correct unsafe conditions.
On an OBAM aircraft the repairman or A&P doing the condition inspection is performing the function of an IA.
There are other reporting requirements buried around the regs. How many know that an EFIS failure in flight is a reportable event?
While not strictly a reporting requirement, would you tell the FAA if the cylinder head on your engine departed when the engine was at 50% of TBO?
Point being, unexpected failures at low in service times indicate an engineering or manufacturing problem. In the case of these governors, they are type certificated parts, in some cases installed on type to certificated engines. The SB referring to experimental aircraft with electronic ignition and higher compression is bogus on all three items. They are doing the SB on my governor because its serial number is on the SB, but the model number is not, it is on an RV-10, but the engine is certified, with stock compression and mags. Only the Mt prop and the airframe are not type certificated.

OK OK.... You win. The SB31 is now public on the MT site with the same wording...

MT is now finally gathering our actual data. Their past assumptions have been quite wrong, as evidenced by the wording of the SB, among other things.
If you've had a failure, or know someone who has, please send the information, serial number, installation, engine type, failure type, etc, to the following.
Martin.albrecht@mt-propeller.com
This could save lives.

Myron, Did MT contact you requesting this information? They have made no effort that I know of so-far to request information about the failure of my governor.

I read that there is no difference other than clocking between the various MT units. If so then why is only the 860-3 and not the 860-4 in the SB

I don't know if MT has a good grip on the situation My 860-5 was listed by serial number under some other model designation. My up-grade was done because of the s/n being listed and because mine is on an RV-10.

Joel,
When my first email to MT in Germany went unanswered, I called Peter and asked for a best contact.
He directed me to Martin Albrecht.
I wrote him with my concerns about the verbiage of the SB, especially the part about EI and high comp cylinders. He answered me next day and asked my details which I sent to him. He answered me back asked for the details of those that I was aware of. That's why I made the post for submissions, but personally think that everyone else should send their info if/how they see fit. I'm not even sure how many of us there are.
Send me your email and I'll forward you a copy of all correspondence.

I have just been in contact with MT in Germany. I told them that my governor was on the list but I had 8.5:1 pistons and Slick mags. Did I need to comply with the SB? ....... YES.......
I suggested to them that the wording was confusing and they might want to re-issue the SB - no response.
