Nov 05, 2021     Autopilot Ground Test - (1 hour) Category: Avionics
Removed rubber grommets interfering with roll linkage at fuselage and confirmed correct autopilot operation of pitch and roll servos.
 
Nov 01, 2021     Magnetometer Calibration - (2 hours) Category: Avionics
Recalibrated magnetometer by rotating plane cw in increments over 360 degrees following on-screen prompts. Continued working through post-install checkout. Reversed motor direction on pitch servo. Aileron and trim movement is sluggish and I suspect it's due to rubbing against the fuselage side rubber grommet.
 
Oct 28, 2021     Flaps and Vibration Test - (4 hours) Category: Avionics
Resolved problem with Flaps by reversing wires 18/19 on the GAD 27 J271 and wires 7/8 on the GAD 27 J273. Successfully ran the vibration test on the avionics by running engine at full RPM. It passed the second time.
 
Oct 08, 2021     GMU 22 Bracket - (2 hours)       Category: Avionics
Fabricated and installed bracket for GMU 22. Confirmed magnetometer functioning. Confirmed there's no interference with landing and nav lights. Re-installed inspection plates on each wing.


 
Oct 04, 2021     ADHS Calibration - (2 hours) Category: Avionics
Successfully calibrate magnetometer today. While still waiting on GMU 22 bracket from Vans, fabricated temporary support from used wing inspection plate. Initially was not getting GPS data to ADHR but after consulting with SteinAir, reconnected GPS coax from XM/GPS antenna from GDL 51 to GPS port on back of PFD display. Followed the steps directed by the ADHS configuration page and with Carlos' help, slowly rotated the airplane supported on auto Dollys, clockwise from North.
 
Aug 26, 2021     VOR Antenna       Category: Avionics
Fabricated fiberglass mount on vertical stabilizer for RAMI VOR antenna. Removed fiberglass cap from vert. stab.


 
Aug 24, 2021     Pitch servo - (3 hours)       Category: Avionics
Installed pitch servo stop bracket and torqued all bolts. This was quite a challenge requiring removal of the servo and mount assembly. Confirmed the stop bracket does not impede full movement of elevator (per. 18.5.2.2, G3X Touch Install Manual). Confirmed G3X recognizes the servo when A/P powered and that the CWS/Disconnect on the control stick is functioning (Open to Low when stick button below PTT trigger is pushed, also hear solenoid engage when releasing).


 
Jul 24, 2021     Replace EGT - (1 hour) Category: Avionics
Replace #4 EGT probe that wasn't working with new probe. Working now.
 
Jul 22, 2021     Pilot Grip - (2 hours)       Category: Avionics
Moved grip back to shorter Tosten stick and crimped new terminals to the micro Molex connector. Drilled new mounting holes and installed. Confirmed that PTT is working, but can't really check out the trim functions until wing and tail assembly.


 
Jul 22, 2021     Flap Position Sensor - (2 hours)       Category: Avionics
Installed Ray-Allen flap position sensor purchased from Vans. They included a 6 pos micro-fit rather than a 3 pos, but was still able to use. They also included the wrong manual section, but I was able to download the correct section 54 from my files. Followed instructions outlined in Sec. 54 with no other deviations. Confirmed full travel of sensor pushrod and flap linear actuator.


 
Jul 20, 2021     Control Stick issues - (1 hour) Category: Avionics
I assembled the control stick with help from SteinAir for the initial engine start, but the PTT didn't work. There could be several reasons, most likely I ruined the micro Molex connectors when relocating the grip to my original stick, which turned out to be a bad decision given the much longer reach of the stock stick. I ordered micro Molex connectors and will return the grip to the Tosten stick and try again.
 
Jul 13, 2021     Brake and Rudder; A/C harness; grounds - (5 hours) Category: Avionics
Re-assembled brake and rudder system and reinstalled in forward fuselage. Decided not to wait on Risse to deliver the needed parts as he promised and will consider whether to install them or return them.

SteinAir parts were delivered and finished fabrication of A/C harness. Ran harness through lightening holes under co-pilot side and then down tunnel to aft of baggage bulkhead. Terminated all grounds and coiled up power wires for later termination.

Ran 14 ga ground wires to left and right side of fuselage at wing attachment. Ran ground wire from fuel pump.

Installed new 6V battery in ELT remote.

Organized coax cable and wire bundles behind CB panel.

Cabin is nearly ready for installation of interior being delivered on Friday.
 
Jul 08, 2021     Grounding; NAV antenna cabling       Category: Avionics
Evaluated grounding with plan to run all grounds to firewall rather than to structure, were possible. This is what I come up with:

LEFT WING
- Pitot Heat (14)
- Landing/Nav Light (14)...Spliced to P2176 on common harness
- L2188 on fuse side and L420 on wing side
- Spare (16)

RIGHT WING
- Roll Servo (16)
- Landing/Nav Light (14)...Spliced to P2176 on common harness
- L2188 on fuse side and L420 on wing side
- Spare (16)

FUSELAGE
- Pitch Servo (16)
- Power outlet (16)
- Tail Light (16)

Ordered additional wire from SteinAir. Installed second ground bus to firewall.

Installed BNC connector to one end of coax and snaked through tunnel to the aft fuselage. Connected BNC end to NAV connection on rear of GTN 650xi. This should be the last antenna.


 
Jul 07, 2021     Canopy Harness Close-Out; Pitot/Static/AoA Install - (6 hours)       Category: Avionics
Coiled up and secured remaining unused wires including: Voltage Regulator, DC spares (2), PMW spare, and discrete spare. Connected loose AML wires to back of A/C switch. Modified thermocouple harness to shorted longer leads so that they are all approximately the same length.

Ran Pitot (red) and AoA (green) tubing through left fuselage side to sub-panel behind the GSU 25C and G5. Protected from potential chafing with edging on the lightening holes use to thread the pneumatic lines. Connected tubing to back of GSU 25C and G5 and cable-tied securely.


 
Jul 06, 2021     Canopy, Defrost Fan, LED Cabin Lights Wiring - (6 hours)       Category: Avionics
Ran two 22 ga wires, green and black, through the wire access holes on the lower left side of the canopy using safety wire. On one end, formed a small loop and fed the safety wire through the forward end and retrieving it using needle nose pliers from the aft hole. Formed another loop on the forward end and twisted stripped ends of each wire through the loop, using duck bill pliers to compress the joint. Crimped spade plugs and shrink-wrapped aft ends. Applied RTV to the aft hole. Adjusted switch and confirmed zero ohms when latch fully closed and infinite ohms with latch partially to fully open. Located purple and green Canopy Open wire and temporarily tied it to green canopy wire. The purple/green wire terminates on pin 42, Discrete #3 in, on the GEA 24 J244 jack.

Located red Defrost Fan wire and routed to left sub panel side. Ran red and black 22 ga wires along canopy frame and connected to red and black wires on defrost fans using a butt splice and shrink tubing.

Installed the red/white LED strip light 1" below the edge of the glare shield. Used a power supply to confirm positive is black wire while red and white are corresponding grounds. Located red and white ground leads from Stein harness.

Connected all canopy, fan, and cabin light wiring to 12 pin molex. Fabricated harness with matching molex from existing loose wires from Stein harness, including two additional ground wires for canopy and fan. Red and white LED grounds already exist from the Stein harness.


 
Jul 05, 2021     ELT Installation - (4 hours)       Category: Avionics
Back from a week off for vacation. Scoured the bottom side of the antenna mount and Installed the whip antenna. Mounted the ELT battery mounting tray and clamps on aft fuselage as described in Sect. 53. Secured audio alarm temporarily on side of battery. Fabricated DIN connector as described in Sect 53 and the ACK Mode E-04 ELT installation manual, pg.8. Ordered a Duracell PX28L battery for remote already installed on panel. Registered the new ELT on the NOAA website https://beaconregistration.noaa.gov/RGDB/index.xhtml. User name RViator62. Battery expiration date is July 29 2025. Need to reregister in two years.


 
Jun 26, 2021     Transponder and COM Antenna Install - (6 hours)       Category: Avionics
Installed a Comant CI-105 (SN #98177) transponder antenna in the pre-drilled holes on the lower rear side of the aft fuselage. Connected existing BNC coax previously installed on page 10-23 to the antenna and the other to the XPDR plug on the GTX-45R transponder. The GTX-45R contains both a mode C and ADS-B transmitter and uses the common antenna. The separate pre-drilled hole in the fuselage floor installed on 26-11 will not be used. GPS position data for the GTX-45R is coming from the GTN-650Xi so no separate GPS antenna connection is required.

Installed a Comant CI-122(SN# 647962 ) VHF communications antenna on the right side fuselage outside bottom. Drilled out four rivets holding antenna doubler with a #12 bit, removed the doubler, and attached the antenna with cork gasket and four #8-26 flat head screws and lock nuts. Fabricated coax cable with BNC connection and inserted into COM plug on back of GTN-650XI. Repeated for left side COM antenna, Comant CI-122 (SN# 647956) and inserted coax on the COM plug of the GTR-20 remote radio.

Labled and cleaned-up cable and wire routing in center chase, not an easy chore given the tight clearances.


 
Jun 25, 2021     GA-57X Antenna Install - (6 hours)       Category: Avionics
Fabricated doubler and mounted Garmin 57X GPS/XM antenna to top of aft fuselage. Fabricated coax from RBG-400 for both GPS antennas and connected to associated LRUs; the GA-57X GPS and XM cables to the GDL-51R data link and the GPS/WAAS cable from the teardrop antenna to the back of the GTN-650Xi.


 
Jun 24, 2021     GA-35 Antenna Install - (3 hours)       Category: Avionics
Fabricated a fuselage doubler for the GA-35 GPS/WAAS antenna. Match drilled doubler holes onto the upper aft fuselage just off-center behind the baggage bulkhead. Dimpled and riveted nut plates on the doubler. After removing rear canopy, dimpled #40 match-drilled holes in fuselage and riveted doubler to fuselage. Installed a GA-35 antenna (part no. 013-00235-00, SN# 196335) using 4 screws provided.


 
Mar 08, 2021     Panel Install continued - (6 hours)       Category: Avionics
Fabricated shelf for GDL 51R and installed unit. Mounted breaker panel after first grinding the right rear lip to provide sufficient clearance. Connected UAT coax to GTX 45 and phone line to ELT. Ran engine terminating leads through firewall pass-throughs.


 
Mar 07, 2021     Panel Install continued - (6 hours)       Category: Avionics
Over the weekend, installed GTN 650xi and audio panel into center stack and connected cable plates. Connected all other cables except GDL-51R which required alternate location than planned. Fabricated shelf to support 51R on forward side of sub-panel where map box opening is. Also reinstalled all panel switches.


 
Mar 05, 2021     Initial Panel Install - (6 hours)       Category: Avionics
Finished installing GTX, GEA 24, GAD 29 onto sub-panel. Disconnected wire bundle from back of panel and installed panel onto frame. Test fit GTN 650xi and audio panel. Inserted and fed wire bundles through access ports....glad I put those in!


 
Mar 04, 2021     LRU Installation on Co-Pilot Side - (3 hours)       Category: Avionics
Decided to install GTX-45R on a hinge to enable servicing.


 
Mar 03, 2021     Pilot side LRU install - (6 hours)       Category: Avionics
Completed installation of pilot side components.

May 26, 2020     Roll Trim Servo - (6 hours)       Category: Avionics
Assembled roll trim servo and temporarily installed on access panel.


 
May 24, 2020     Roll Servo Installation - (4 hours)       Category: Avionics
Installed Garmin GMA-28 roll servo obtained from SteinAir and Van's install kit. Fabricated push-rod by tapping ends for 1/4" bearings. Installed stop bracket over servo mount bracket as approved by Garmin G3X install instructions using the four screws supplied and was satisfied the stop cage was securely attached. Checked travel and for interference. Found that I had to move the bearing attach point to the far end of the cam rather than closer hole to prevent interference between the bearing attach screw and stop bracket attach screws. Confirmed upward aileron deflection limited by mechanical stop at inboard hinge and downward deflection limited by servo stop bracket. Enlarged molex support hole slightly to clear molex plug.
