Oshkosh or Bust – Airworthiness Inspection Scheduled!

Thanks to some outstanding customer support from Dynon and B&C Specialty Products, we received replacement parts that have let us recover from our misstep in time to still make it to #OSH14 with an airworthiness certificate.  No time for a first flight, but hopefully the FAA inspection and sign off will take place between now and the start of the EAA Convention.

Yes!  We have a working PFD again!

We are ready for the FAA airworthiness inspection!  The project will be in the Homebuilders Hangar at EAA AirVenture Oshkosh 2014.  Stop by and see it in person._MG_0370Until next time….

Final TC Visit, Fuel Tank Calibration….and then a Setback

The best way to make sure you are ready for your final inspection is to have an EAA Technical Counselor do a final inspection just prior to having the FAA coming out.  That way you can fix all the things that would be a problem during the FAA’s airworthiness inspection.  The last thing we homebuilders want is for the FAA to think we don’t know what we are doing by having lots of squawks.

Fortunately for us our Technical Counselor, Joe Norris, is a former Designated Airworthiness Representative (DAR) so he knows exactly what is going to be an issue during the airworthiness inspection.

Here Joe is inspecting the throttle and mixture linkages.

Joe reviewed our FAA paperwork just to make sure we didn’t miss anything.  Other than a few minor items, Joe felt we had everything in order.

With the thumbs up from Joe, Phil and Jerry could now rivet in the channel covering up the stick._MG_0066

So we were down to only calibrating the fuel senders.  Step one was to drain out the usable fuel._MG_7593

And here is where we suffered a setback.  During our fuel calibration, we decided to switch to an auxilary battery since we had drained down the one on-board.  Unfortunately, we mistakenly hooked it up in reverse.  NOT good for our avionics!  Shortly thereafter our PFD went dark.  We left the hangar that day depressed.

The good news is both Dynon Avionics and B&C Specialty Products have provided excellent customer support as we troubleshoot our error.  Our thanks go out to both companies.

So here is where we stand.  The damage isn’t that bad but we had to pull the PFD and transponder to ship back to Dynon.  The airworthiness inspection will have to wait until after AirVenture 2014.  Disappointing but we will overcome this setback and have her flying right after convention!

Until next time…probably after AirVenture 2014.

Fuel Flow Test and a Visit from Jack

EAA strongly encourages all homebuilders to perform fuel flow testing prior to flight testing.  Although not required for certification, the time to figure out if you have any fuel flow issues is on the ground.  For more info on fuel flow testing, watch the EAA webinar on Fuel System Testing.

Tim, Charlie (me), John and Tom preparing for the test.  I’m removing the fuel line at the carb inlet. _MG_6837

Not to waste any time, while we are doing the level flight test Jerry is working on installing the ELT in the tail section._MG_6851

Level flight testing complete, now it is time to test for high angle of attack by tying the tail down._MG_6952

Tom checking the angle._MG_7004

Testing in process.  As it turns out, we do in fact need a fuel pump when the aircraft is in a high angle of attack with minimum fuel on-board.  Perfect example of why you do the test!_MG_7014

Experimental sticker installed on entrance to the cockpit._MG_6567

EAA chairman Jack Pelton stopped by to check out the progress and give the staff some encouragement._MG_7114

Of course he couldn’t resist trying on the aircraft.  _MG_7126

It’s Alive! Weight & Balance and Engine Run

A couple of major milestone are in the books:  weight and balance complete and we fired her up for the first time.  Yes!

I’m thrilled that she will make to AirVenture under her own power!

4 Sessions, Lots of Progress, First Radio Call!

We had four build sessions since our last update.  EAA SportAir Workshop instructors Dick and Bob Koehler were in town over the weekend to lend a hand.  With their help, we made so much progress.  Here are just a few of the things completed:

  • Oil door in cowling
  • Angle of attack probe mounted
  • Primer line run and secured
  • Installed and wired 12V outlet
  • Ray Allen stick grips installed
  • EGT sensors installed and secured
  • CHT sensors installed and secured
  • Spark plugs installed and torqued
  • Fuel lines completed
  • Fuel flow sensor installed and secured
  • Oil temp sensor installed and secured
  • Breather tube installed and secured
  • Engine dataplate reinstalled

As the wiring guy, Tom had the unenviable task of working under the panel._MG_9965

The joys of aircraft building….climbing into the tail section.  Not even sure who this is!_MG_0166

Installing the dataplate on the engine.  You have to be extremely careful or your can drill all the way through the case (which would totally ruin your day)._MG_0286

Lots of adel clamps installed with the goal of securing and cleaning up all the hoses and wires.  Oil pressure sensor installed._MG_0345

Jerry with the nutplates riveted on the AOA mount.  These were the first driven rivets Jerry has ever done even._MG_0351

Matt installed the seat belts and shoulder harnesses._MG_0366

Here is a good shot showing our Ray Allen stick grips installed.  We went with the G205. _MG_0387

Once Bob and I had the primer line run, Tim stepped in to secure it and some wiring. Tim making sure the stick and primer/wiring bundle don’t rub._MG_0730

I used EZ Turn “fuel lube” to seal the NPT side of our fuel line fittings.  (You don’t use it on the flared fitting side, just the pipe thread)._MG_0410

Always skip the first thread and be careful not to have any sealant on the end of the fitting as it could block the fuel flow._MG_0408

Installing the fitting on the fuel pump. _MG_0415

Jerry installed the static ports._MG_0849

Static port installed._MG_0852

Jim working on an access cover. _MG_0858

Lots of activity going on._MG_0761

I spent some time making the hoses to run from the firewall to the carburetor.  These stainless steel braided hoses are pretty easy to make and look great installed.  Here I am cutting the hose._MG_0705

Tightening up the fitting.  Note the tape I use to make sure the hose end doesn’t slip._MG_0774

After completing the hose, I ran some mineral spirits through the hose and blew it out with compressed air to make sure no debris was in the line._MG_0684

With the hoses complete, we should be able to test the fuel system soon._MG_0881

Tracy re-installing the prop with the spinner back plate in position. _MG_0813

Cummings Spinner installed.  Looks much nicer with the spinner.    _MG_0868

Tom testing the stick selector circuit._MG_9839

Bob and I securing the carb heat cable.  _MG_9846

Dick and Tom working on the panel.  (No way Dick was climbing in there)._MG_9924

Everyone head down and working hard._MG_9946

Dick heating up some shrink tubing to complete some wiring._MG_9953

With the comm antenna installed, Tom called OSH ground for a radio check….loud and clear!_MG_0174

Until next time….
