Back to heavy metal work

Posted on by

One task that I want to document for others I forgot to mention is modifying the tunnel cover around the Control Approach rudder pedals.  The cable attach arms are relocated inside the tunnel so slots need to be cut for them to move freely in the cover.  I measured their arc and marked the tunnel cover where I wanted to split it into two pieces.  Before cutting, I marked and drilled a center plate to hold nut plates which will allow me to screw the two pieces back together.  It was a pretty simple modification as was cutting the slots for the arms in each piece.  Again, I’m trying to consider maintenance and access down the road as much as I can.

I also took the time to modify the seat rails since I got the Aerosport seat levers.  Others have described this mod and it makes removal of the seats a snap.  Step one is to remove the delrin guides from the seat bottoms and trim the first 1 ½” off followed by reinstalling them.  This allows the seat to be slide rearward on the rails and then tilted around the flap tube cover with the necessary clearance.  I then removed the aft rail stop and drilled through the rail into the plate below.  Installing nut plates below the plates lets you put bolts in place of the screw and nut on the stop.  Now, I can get to the bolts from the top down eliminating the need to reach under the seat plate to get the lock off, allowing the seat to slide freely rearward.  It all makes sense when you look at it.

I’m trying to knock out some little side tasks along the way now in the spare time.  I used some excess epoxy from a door filling session to install the front vent NACA scoops.  I drilled a few holes and used clecos to hold them in place while the flox cured overnight.  I don’t have proseal and didn’t want to use any silicone on the area since it will be painted.  With minimal flexing and a good scuffing on both surfaces, I am confident the epoxy will hold these just fine long term.  The scat tube will have a short run from there to the Aerosport vents that I installed in the instrument panel.

I also performed a quasi service bulletin from Sean at Plane Around.  When I received the lights from him for the overhead and doors, several had bad boards which he promptly replaced.  I got a call from him with an interesting finding.  He used a brass wire over a piece of foam to hold the LED boards inside the aluminum and plastic housing.  He found that in a few instances, the wire was touching the board and shorting out LEDs.  Awesome service!  He called and suggested using a different method such as silicone which is an easy solution.  I removed all of the installed lights and completed the rework after ensuring all LEDs checked good.  I took the opportunity to install the micro molex connectors on the remaining few assemblies as well.

Service bulletin complied with in accordance with published guidance, OPS check good!

And finally, another cleanup item to mention was the addition to the hangar family.  While she hasn’t been officially named, our new Best Tugs Alpha 2 arrived!  I ordered this at OSH last year to use on the DA-40 we fly now and for long term with the RV.  It cost a pretty chunk of change (plastic, let’s be honest) but man is it nice.  It will save my twice-operated on back for years to come and is really handy to maneuver the airplane around.  It took a bit of practice one afternoon but now it’s just like pushing a shopping cart!  I requested the smooth cover with the intention of having it painted by Jonathan to match the RV but didn’t realize the red anodizing was going to arrive.  Oh well, not the end of the world.

Bite my shiny metal bottom…skin

Posted on by

After a visit from my EAA chapter tech counselor and a great report card, I was confident in buttoning up the wings with the bottom skins.  It takes a lot of clecos to position the skins and a lot of time spent drilling and deburring.  Then the dimpling fun begins and priming.  


The riveting process is another dreaded task, besides building the tanks.  You have to start with the rear spar and bend the skins up.  I used duct tape to help hold them in position and allowing me to rivet a few rivets at a time working from the rear down each rib.  


Overall, it really wasn’t bad.  I managed to get the entire skin done alone except for three rivets where my arms just weren’t long enough.  I had the wife man the gun for those on the j-channel.


On the left wing, I installed the pitot mount. I also got the aileron trim servo hooked up mechanically and electrically with a micro Molex connector.  I was worried that the springs on the setup would be a pain to install, but again, it wasn’t too bad.  No picture, as once the springs are on, the access panel goes on.

Finally, before replacing the aileron and flaps, I complied with the service bulletin regarding the aileron mounting bracket. Other builds have suffered cracking and the gap fairing must be cut back to allow inspections at regular intervals.  Replacing it is not recommended per Vans, as it can cause more damage trying to remove the rivets than replacing it.   A quick job with the Dremel tool.

Service Bulletins

While having some down time at home that I can’t do much productive anything with, I decided to research quite a few things while lying in bed after surgery.  One of those was service bulletins.  There are a handful out there for the RV-10 and are a lot like AD’s issued by the FAA, but they are not mandatory by law.  Highly recommended, however, so in the home built world, you comply with them.  With this being a build log, I wanted to document them here and then I’ll make the associated entries in the air frame log book once I have one.

The empenage kit (oldest original kit) was delivered in October 2005 to the original builder, thus I have only addressed those SB’s relating to the dates affecting our kits.

SB 06-2-3 is for the vertical stabilizer rudder mount.  This SB was completed by the original builder and complies with all aspects of the SB.  I could not get a good picture inside a tiny access hole, however, visually confirmed the doubler plate is in place inside the main spar of the VS.

SB 06-9-20 is for the trim cable anchor nut on the elevators.  While our kit does have the double welded nut, I chose to upgrade to the CNC machined piece by IFLYRV10.com.

SB 08-6-1 is for the F-1010 bulkhead near the vertical stabilizer in the tail cone.  My kit came with the SB contents and I completed it as part of the original build of the tail cone.

SB 16-03-28 is for the aileron hinge brackets possibly cracking on the inboard aileron mount.  I have removed the portion of the gap fairing to allow future inspection and no further action is needed until flying, at which time an annual inspection of the bracket must be made and noted in the log.

There are other SB’s that will affect our build, however, I have not gotten to that stage of the build yet, so will cover it in another post.
