The Mission:

I am building an airplane. I really can't tell you how weird it sounds to me to hear those words in my head as I type. I am keeping this blog as an adjunct to my written log, which is required to comply with FAA requirements for Experimental Aircraft construction. My son Doug is my partner in this project. There are two goals: to build the best, safest, and yes, COOLEST, airplane we can, and to allow Doug to acquire some truly awesome experiences, not to mention building skills. Thanks for viewing.



How to use this blog

The most current post is displayed on this opening page. To access the older posts, click on the "Blog Archive" on the right hand side. The drop down menu is arranged by the month and lists the posts, by title and by date posted, in reverse chronological order.

I will arrange the hypertext links to other websites I find interesting better some day, but they are at the bottom.

If you navigate to my first post, there is a link to my luthiery pages. I miss working with wood. Aluminum is nice, but it's boring. Give me a highly figured maple any day!

Crotch straps

I could have said "Hookers".  It would have made for an equally interesting, but misleading chapter title.  I have been working on many onerous tasks recently, in parallel with working the punch list I got from Wally, my technical counselor.  I am trying to get ready for a first engine start soon.  After that, the plane goes to the painter.  I am painting early in the project because I think it will be most time efficient, and I don't want to compromise on the painting.  It is my opinion that the painter can do a better job if he paints an unassembled plane, and I don't want to tear apart a plane that is already flying.

So about the hookers and the crotch straps...

My five point restraint harnesses are made by Hooker, and I needed to rivet in the anchors for the crotch straps before I put the floors in.

Progress recently:

Spinner is now firmly and finally on

The stationary parts aft of the constant speed prop

Crotch strap anchor riveted in pilot side

Rudder cables attached to allow brakes to be usable

The empennage is on for good!!

Some further milestones

I'm still plugging away.  I had a visit from my technical counselor, Wally Anderson, of Synergy Air.  His attitude is that building an airplane is no more or less than obsessively and compulsively making "to do" lists and completing them.  Eventually, you run out of things to put on the lists, and you have an airplane.    

The first photo shows the nutplates that hold the spinner on.  There are several cute ways to do this that hide the screws, but I'm not doing any of them.  I am going to have visible screws on both the front and aft plates:

Nutplates

To hide the piano wire that holds the top and bottom cowling together, I fabbed two plates of aluminum, and made a recess to hold them out of fiberglass.  And yes, more nutplates.

The piano wire will be oriented curve in when I close the cover

More nutplates to hold top and bottom cowling at cooling aperture

Built up forward portion of cowling aft of spinner for cosmetic reasons

There are days when I look in to the avionics bays and think, "this is pure chaos":



But then I get back to work bringing order to the chaos, one "to do" list at a time



These two photos are to document that I complied with a service bulletin from Andair that the screws holding the selector valve together are tight.

I checked the torque

I applied torque seal

Doug checks out the seating position.  I am going to stop here and note that the center console is an ABSOLUTE PITA to install.  If I build another RV I am definitely not doing it.  Except for the fact that the finished product, at least on the ground, is a joy to sit in.  Look at how naturally Doug's arms rest and how comfortably the throttle and stick fall in to his hands.  This is ergonomically perfect.  Better than an F16 (or a Cirrus)



I also made my first official log book entry (for the aircraft logbook; not the builder's logbook)

First log entry

Wally made many DAR-like observations.  I took notes and in parallel with building, I am working through his suggestions.  One was to hold the fuel line down lower so it didn't ride upward toward the upper cowling.


And this is my solution to where to put the "red cube".  It needs a five inch straight run prior to the cube, a level surface, relatively good support, and should be downstream of the mechanical pump.  Mine is here, next to the fuel distribution spider.




More nutplates...


The ELT is supposed to be mounted"as far aft as possible",  "in line with the direction of flight", and "affixed to a rigid structural assembly".  I think I have satisfied the requirements here under the empenage fairing.




Wow, I am impressed that you made it all the way down here!
