airport is still an airport & 701 Flap repairs 99.9% complete

Been a while since I posted, but the new job is taking up most of my days and weekends are escaping us because now the outdoor work around the house begins.  Excuses aren't welcome, but the grass doesn't stop growing.

Much earlier in this blog (my first post actually - click here) I spoke of all the work my mentor Barry Morris and I put into trying to promote and develop the South River / Sundridge Airport.  Unfortunately, Barry passed away before seeing the local municipalities get their acts together on this important community asset.

I honestly thought all was lost regarding the airport.  Three times the municipality almost sold the property to non-aviation interests who wanted to turn it into a number of non-aviation purposes.  How disheartening.... however....

I'm ecstatic to say the property was sold to a couple of business men that are enthusiastic aviation people who want to continue to develop the property PROPERLY as a municipal airport, including paving a runway and installing lighting.  "Build it and they will come...." is a quote from the 1989 "Field of Dreams".  How perfectly appropriate!

On the 12th of May, the new owners, in conjunction with COPA and the local flying club hosted a fly-in pancake breakfast.  Ron, his wife Donna and I attended and joined the fun.

Over 40 aircraft from all over southern Ontario attended, it was wonderful!  The new owner couldn't wipe the smile off his face!  There are a bunch of photos on the airport Facebook page. I was way to busy chatting with friends to take a bunch of pictures but here are a few:

​Of course one of the more interesting planes that arrived was a newly kit built Zenair 750 STOL, just like I'm building.  Spoke at length with the owner who has about 80 hours on the airframe after completing it last year just south of us in Emsdale.  The biggest thing he recommended was keep at it.  There is a ton of stuff he still wants to do cosmetically (more paint, etc) but he's having way too much fun flying! He let me sit in it too and I'm even more convinced that I've made the right choice :)

Vinyl 3M registration and maple leaf. I think a nice blue would look good against bare (polished?) aluminum too.

Version 3 "bubble" doors too. The visibility from the cockpit is fantastic in the 750.

The chance to see another completed 750 was a real good motivator!
​
The 701 flap repair is almost done.  Some final trimming to be done, but the skin wrapped real nice and the joining patch turned out real smooth.  Happy to be moving on to building my own flaps shortly and not fighting with other people's mistakes.

Final rivets in and correct length to match wing extension. Lessons learned here will come in real handy for my 750 flaps and the other 701 wing extension.

Extension joint. This really stiffens everything up and adds very little weight.
 
Ron has never been very happy with the pinched trailing edge design of the wings and flaps on the 701.  The original builder (as I've been saying all along) never really paid attention and the trailing edge isn't nearly straight enough.  The pinched rivets called for in the plans really add a lot of drag too.

​The plans in the 750 model I'm building wraps the skins forward to the spar, making the trailing edge much cleaner both in appearance and more importantly aerodynamically.  Every little bit helps!

To clean things up, we'll be adding a trailing edge strip and attach it with flush rivets.  Here, we're fitting the trailing edge "cover".  The first one worked real well, I'll add a picture when the one is done.

We plan on building flaps and slaps at the same time for three new 701's and my 750 and new slats for this repaired 701.  This sounds like a ton of work and it is, but there are huge time  savings because they are dimensionally the same, meaning we only have to set up jigs once.

I spent a couple of hours the other night bending my slat ribs on the forming block.  The 750 slats are identical to the 701, so I didn't need to make my own forms for this.  The only adjustment needed was one tooling hole on the tail end which is different:

So they turned out ok, but will need some clean up.  Not a big deal, but not a nice as I would have liked.

Next up, finish skinning the 701 wing extension.  Here is a graphic of what I have complete and ready to assemble (highlighted in blue).  Lots of stuff ready to be bent still.

I read your article with interest, Jason, and am so happy the airport is to remain operating as an airport. Barry put so much of his heart and soul into trying to build that airport. He had the knowledge, but the municipalities' support was lacking because they never did see the fact that airports in small communities are economic drivers. The new owner, I believe, Barry knew him as his name is very familiar to me. If he started with Twin Otters, Dash 7's or Dash 8's earlier in his career they could crossed paths then as Barry could have done his training. Anyway, he would be happy that it is now in the hands of aviation enthusiasts.
