In recent attempts to get EASA to pay attention to safety issues (not Arcus),
I've learned a few things.

1) Fill out the EASA safety form or you'll be ignored

I was told "you need to fill out an incident report so it gets 'in the system'".
See: https://www.aviationreporting.eu/AviationReporting/OFR.aspx?occsrc=1&countrycode=EASA

Lame-brain IT morons who designed this thing excluded support for pictures,
so before you even start make sure relevant pictures are stored on web
and you have URLs for pictures at hand (include URLs in EASA submission).
Don't complain about EASA until you have filled out their form.
Then you can complain bitterly ;-)

2) Motors are considered minor accessories

I received the following in an email:

Apart from the actions we take in this matter, please let us point out that the pilot of a powered glider shall always have in mind, that it might be necessary to operate his aircraft as a pure glider. The engine of a powered glider, predefined by airworthiness requirements JAR/CS-22, does not meet the same safety standards as a "Part-E" engine of a motorplane.

The flight training  for powered gliders shall take into account, that loss of engine power may occur anytime, and result in a scenario, which is comparable to a cable break during a winch launch or an aerotow. This deviation to the operation of a motorplane  is reflected in several paragraphs of the airworthiness requirements JAR/CS-22, applicable for a powered glider. Examples are the specifications for engines, used for powered gliders (JAR/CS-22 Subpart H) that are less stringent than those for powered aircraft (CS-23). Moreover, requirements for software are not mentioned in the JAR/CS-22 at all - contrary to the specification for large aeroplanes (CS-25).

Dear Mr. Nadler, we are fully aware of our task and we do our best to meet and reduce unsafe conditions in glider aviation. Following this, we appreciate very much the information you supplied to our desk.

So, unless its a fire or structural damage, its not at the top of their list.

Hope this is helpful!
Best Regards, Dave

PS: I'm trying to get some OSTIV projects going to address motor-glider 'issues'.

Thank you Dave!
However SH should inform if it knows the problem, I think...

Best regards, Roberto

No Problem!
But PLEASE fill out the EASA form for this and other issues.
Thanks,
Best Regards, Dave

Hi Roberto. I also need to replace these. The engine has 56hrs on it. I am interested to know how you replaced them. 

Are they glued into the carbon fibre pylon or did they push out easily? Did you glue the new ones back in and if so, what kind of glue did you use?

Kind regards,
