Re: Platinum Pacer Wings
I haven’t spoke with Eddie for a month or so. He’s waiting on his DER. On the subject do do I think he’ll get the STC? Feels like he will...but then again I’ve offered to throw money at the DER to get the job done....so I guess...the DER will get around to it...someday.

Having spend a lot of time on my STC for this modification, the DER was not be cheap, even when I was doing most of the work. The testing procedures that the FAA engineers were talking about would have added quite a bit more to the cost to my project. After all these expenses a financial return was not very promising. But, making money was not my goal. The complications and costs caused me to finally give up. Now I'm happily flying my Bushmaster.

I was hoping to get back up to AK this summer and drop in on Eddie. But, the fires may not make the trip worth while. I've had too much experience flying through smoke last summer in WA.

Same thing goes for trying to get the stick control STC approved.... Too much money to get approved for not a lot of return so I shelved it...

Re: Platinum Pacer Wings
That spar splice is not legal from everything I have seen. Looks like another snowball.

Re: Platinum Pacer Wings
It’s not a splice...someone’s idea of reinforcing the front spar. Trimmer’s engineers say the rear spar is the weak point if the aileron is moved out. No requirement to strengthen the front spar so on his wing...so?.?? What duh hay? When I found that reinforcement...I felt the fabric had to come off...I thought it was a spice too! I do have one 12 rib front spar and a full length front spar extrusion...if I have to replace those spars? Do I?...gaud this sucks! All that time and money...

Re: Platinum Pacer Wings
I’m looking for some advice... trying to identify if the 0.050” plate outboard of the wing strut attachment can be documented and approved.
Here’s my interpretation:
AC43.13-1B
4-50-b A repair must be equal to the original structure, but not stronger or stiffer which will cause stress concentration or alter the resonance frequency of the structure. I don’t believe this applies.
Rivets are 3/16” AN 442 Flat head MS20470 the alloy is 2117T. Rivet diameter is nearly 3X the spar web thickness. Rivet spacing does not conform to AC43.13 for splice repair. The edge distance is okay. This is not a splice repair and the spars do not appear to have any damage to the spar web which indicates the rivet spacing greater than 6X the rivet diameter is not an issue.
The plate thickness is 0.050” of an unknown aluminum alloy.
Thoughts?
