Finish Kit (and others for Final Assembly)



Magnetometer Interference and Joystick re-position ( 5 hrs )

Repeated full Magnetometer Interference test.  Again, Pitot Heat was only 12% (way below 100% limit), and quickly settled to zero.  Passed overall - the aileron movement full right was worst at 43%.   Note for future diagnosis, maintenance:  LH Wing Root has red 14ga wire from Pitot as 3rd ground wire attached to Fuse (see pic below).   Moved on to another issue to resolve:  full elevator down/full right aileron has Josten grip on top of LH Joystick contacting throttle knob (approx 1/4" interference), I adjusted pushrod tying LH to RH joysticks so leans 1/4" to left (non-parallel with RH joystick). This required same adjustment opposite direction for pushrod (CS0005?) going to LH Wing.  Simultaneously I used Aileron template and bellcrank template to insure maintained perfect alignment of both LH and RH ailerons.  Very time consuming to re-assemble below joystick with required washers - even with my "washer wrenches" it took several attempts for each washer.  Now I have zero contact with either LH or RH joystick.  My DAR confirmed FAA criteria for airworthiness is no contact throughout joystick travel (even though extreme positions, and I have to move leg out of the way).
Red 14ga ground wire from Pitot to Fuse side 
in LH Wing root area.   
Passed Magnetometer interference test.  Now Pitot
heat is one of lower amounts. The worst case listed
 at 11 seconds was aileron full left.


Prior to adjusting LH Joystick 1/4" to Left so no contact with
Throttle.  The T shape on Josten grip contributed to conflict,
but mostly moving the T/P/M controls from below panel,
to along bottom perimeter of panel was main culprit.
