Progress update... final stages

Well, progress has been steady.

Magnetometer and compass calibrated.  Magnetometer had to go back to Dynon, and they just sent me a new one.  I had standard AN bolts fastening the magnetometer, which are now replaced with brass.

The header tank sensors I used are... well... garbage.  Not going to live with that, so the tank is out and new sensors ordered.  Tank removed.  Parts arrive today (2/11), hoping to get the new bungs welded in tomorrow.  Have to create a circuit for the display.  Actually looking forward to that.  

Aircraft is at the paint shop for touch ups and polishing.  I still have access, but its on the other side of the field... lots of trips back and forth for tools.

Had a fuel leak around the pump assemblies.  Fixed.

Another brake leak on the park brake valve.  Fixed.  Need to top up the reservoir.

Prop settings updated for UL520T.  Was set for UL520IS.

Started log books / maintenance schedule / out of phase tasks.  Draft of prop log / maintenance schedule, etc complete and reviewed by peers.  Minor changes recommended.

Things left to do:

  1. Finish log books
  2. Print W&B
  3. Lower aft strut fairing fasteners
  4. Set fine pitch stop on prop.
  5. Aft belly inspection panel
  6. Document all control surface deflections.
After that, its time to get flying again and get my training plan ironed out.

Nice photo shoot on Sunday.

Lots and lots of progress on little things...

Progress is fast and furious.

Aileron bolts safety wired.  Boy, that was fun.  Had to make tabs for the outboard bolts to tie to.

Had another park brake valve leak.  5606 all down the belly (well, one long stream).  One fitting was not quite tight.  Tested extensively and no leak, and fluid level holding steady.

Compass swung and magnetometer received back from repair and calibrated.  Initially the magnetometer would not calibrate as I had used standard AN3 bolts to mount it.  Switched to brass, and all good now.

Full power run for 3 minutes.  Ran great.  Have downloaded engine logs and need to review.  Oil temps creaped up into the yellow.  Temp spread on intercooler was 26 degrees.  Prop spun up to 2680, but then came down to 2600.  Need to check prop settings.

Autopilot bridals for capstans installed.  Had to fine tune the forward elevator bracket, but got it.  Initial autopilot calibration complete.

Shims installed on main gear.  Looks good now.

All cotter pins, etc verified in aileron and flap systems.  All turnbuckles safetied.

Left wing servo tab pushrod fabricated and installed.  Perfect.

Aileron rigging complete and dead on.

Wing tips attached with screws and not clecos :-)

What remains...
  • Logbooks and paperwork pre final inspection
  • Paint touch up and polishing
  • Header tank sensors... figure out a new plan.
  • Fuel tank calibration.  I have a sticky sensor, or a bad wire in the left aux tank
  • Exterior placards (door open, fuel tanks, etc).
  • Install all inspection panels after final inspection
