In most cases, TBO is only a recommendation even on type certificated engines and
aircraft. The only hard and fast time-in-service or calendar/hour limitations
appear under "Airworthiness Limitations", usually chapter 4 in the maintenance
manual. If the TBO appears here it is a requirement, if not it is a recommendation.

All, TBO is an advertising claim and nothing more. It doesn't matter who
makes it, what they set it at, or anything else. Sometimes they make sense,
other times they are ridiculous. Has anybody ever made the 1000 hours that
Hirth claims?
There is only one service directive that MUST be complied with and that is
an Airworthiness Directive (AD) issued by the FAA. Even then you are
allowed to find an alternate method of compliance (AMOC) if you can prove
that it accomplishes the intent of the AD. Every other recommendation, and
that is all they are, by a manufacturer is advisory in nature.
I've attached Mike Busch's excellent article from the December 2011 issue
of "Sport Aviation" that covers the subject quite well. Thanks to SA for
allowing its republication here. All copyright and ownership of the article

"Safety Directives" from the company are also mandatory if they are a flight safety
issue. So AD's from the FAA and SD's from the Mfg are mandatory.
SB's, SA's and SI's are not compulsory even if they have mandatory stamped on them,
but you'd be wise to heed them.
Some Mfg's don't seem to understand the difference between an SB or an SD.

912 TBO.
Right around July 2006 the 912 series engine was allowed to go to a 2000 hr TBO
with the replacement of the oil pressure regulator plug screw and spring and
it was advisable to include the new oil pressure regulator cone, but not mandatory.
All three parts cost around $80 and it took 5 minutes to replace them. The
engines prior to this time still have the 1500 hr. TBO unless you not only
changed the parts above, but the crankcase which made it cost prohibitive. The
Rotax SB that addresses this is SB-912-057UL. This will give you the specific
serial number cut off for the 1500 to the 2000 hr TBO.

Since we are on the subject of ADs and SDs... are these REQUIRED for experimental
(non-certified) aircraft or are they only required when the engine is installed
on Certified Aircraft (ie. Cessnas, Pipers, etc.)?

Attached are pictures of my "new" old Ultrastar that my Dad built, and
that we flew back in the late 80's, and early 90's. I am getting it
ready to fly again.

Good on you, Mate! -- great project, getting an aircraft, old or not, flying again.
Congratulations. I'm sure the Ultrastar appreciates it too, and will treat
you kindly. She loox nice, good paint job. Recent?
Good luck and fair winds,

Thank you Russ. Everything is original. My Dad and I quit flying the thing
when we started building our RV-4. Now I am going full circle!

Non Kolb post
Does anybody have a non-airworthy or even junky 912 exhaust to get rid of? A friend
of mine is putting a 912 on an airboat, and has everything but the exhaust.
If so, please PM me off-list.
Thanks.

Experimental's are usually exempt, unless the FAA AD makes it a flight safety issue.
