Chris,
In the XS you probably have batteries, or ELT equipment and of course rudde
r cables nearby the servo floor attachment.
It is highly likely that no provision or access panel has been made over th
e 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 eng
ineering I=92m afraid, and is done for expedient construction in the manual
.
Of course in some countries this may be a major modification and one has to
go to the approving authority or be approved by an inspector. Do so.
In a stock XS:
Remove the cotter pin and nut. Use a cloth or something as a dam to preven
t loss of the spacers/washers when ready to pull the AN 4-23 bolt. Failure
to do this may result in hours of hunting for parts dropped.
Procure an angle drill and small hole saw or similar to simply bore through
the wood support to gain sufficient clearance to remove the bolt outboard.
Disconnect the linear drive actuator from the flap bar and unplug/disconnec
t the wiring.
Again, standing on one=92s head in the baggage bay, reach in and undo the b
olt connecting the actuator to the flap cross bar using appropriate sockets
and extension, mirrors, lights and patience.
I prefer to do this with the wings off and use an assistant to peer through
the flap tube arcs in the fuselage side and hand me tools.
Installation is as frustrating as removal.
I always make a plug for my flap drive for troubleshooting and maintenance.
These linear drives rarely fail, but can.
"If you make it convenient to maintain, easy to access, it seems it will ne
ver fail."
Below is how I do my baggage bay floors to assure access. Normally a 4 inc
h hole in the floor and the hole in one of the ribs is done during construc
tion only as needed to gain access and provide a viewing hole.
Ensure your country modification procedures are followed. In the US I simp
ly made sure I had access. If you make a hole in an airplane or support, o
ne must assure the reinforcement is as structurally sound.

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 f
uselage floor (Build manual 28T). Removal of the AN4-23 bolt is not possibl
e owing to location of the baggage bay supporting structure. Please advise
how to remove the existing actuator.
