Hi,

l I need to replace my electric flap actuator, ie both motor and lead screw assembly. However, the mounting bracket FL26 is bonded and bolted to the fuselage floor (Build manual 28T). Removal of the AN4-23 bolt is not possible owing to location of the baggage bay supporting structure. Please advise how to remove the existing actuator.

Chris,



In the XS you probably have batteries, or ELT equipment and of course rudder cables nearby the servo floor attachment.



It is highly likely that no provision or access panel has been made over the flap actuator in the baggage bay floor or through the floor supports.



This is a travesty of failure to plan for future maintenance and proper engineering I’m afraid, and is done for expedient construction in the manual

Hi Bud,

Thanks for your response. I concur with your views.

I am on the final lap of a 2 year restoration when the actuator failed on a shakedown flight. 

I may have to drill a hole in one of the baggage bay support panels in order to remove the AN4-23 bolt from FL26. This may allow me to change to motor and retain the existing lead screw. 

If I can access the other end of the lead screw with the wings and flaps removed from the fuselage, I will swap out the complete actuator. I would appreciate your view on whether or not this is possible. 

Many thanks for your notes, published on the Europa Club site. They have already been hugely helpful.

Chris, 

I have not changed out the motor in the XS actuator I'm afraid.  The manufacturers name is on the motor normally and if you can read it, they can supply the info.

On my Motion industries  linear actuator I bought a kit from them with new brushes and it was fairly easy to repair.  



Best Regards,

Bud Yerly

Cut a hole in the baggage bay support to allow access to the bolt. It's only plywood supported by fibreglass so a couple of small holes wouldn't be a problem.
