The ASTM referred to is a set of standards similar to/like ISO 9000/1 etc. All it means is that the engine has been designed and built to a certain standard. Does not mean it is a certified aircraft engine.
HKS also complies and meets the ASTM F2339-06 standards and they quite categorically state that it is NOT a certified engine.
Rotax don't state anywhere that it is a certified engine, only that it complies with the relevant ASTM standard
You can get out of the hole now

Mr Ducky,
JA BUT, no where did I stated CERTIFIED anywhere, just compliant and certificated. What I was trying to state that in my old Manual is stated that:
This is not a certificated aircraft engine. It has not received any safety or durability testing and conforms to no aircraft standards.
The latest wording in their CERTIFICATE contradict that:
Rotax hereby declares that the aircraft engine.... <SNIP>
No features or characteristics are found which would make the engine unsafe provided it is installed, operated and maintained in accordance with instructions....
We'll it is a good thing that the motor is now considered BETTER than in the past,
Bad thing for us trying to use the line in old manuals for our cause.
That is what I am trying to say, we can't use that line in the manual for our defense no more...
Both again for reference:
Operators Manual:
Rotax Certificate:
