Installing access panels in a PA-28 wing with a CNC cut template and nibbler

When the FAA first proposed the AD, a friend of mine told me that a LOT of people were going to need to install Piper Access Hole Kit part number 765-106V. I was scrambling to find more work at the time, so I designed and CNC cut a template to make this process easy. I shot this footage of using the template, and planned to post as soon as I knew the AD number, being ready to market the templates. Then the Embry Riddle plane went down, and the AD process got really funky. I also got really busy. (Google Morris Models Radial Engine.) A few days ago, another friend asked for help installing the panels, so I dusted off the template and the old footage. I figured I'd go ahead and show it. If there is enough interest, I can still make these. They would cost $100 each made from aluminum and good for about 20 uses (the holes get wallowed out with repeat use). I left off using the smaller template in the baggage compartment - but the process is similar. Let me know if you are interested in the templates.

Great video. Those templates definitely look like they make the job a lot easier. I have been an A&P for about 17 years now and I always find your videos very informational and learn something new or at least refresh my memory. Thanks again

If that’s the official Piper panels the size is way more than anything needed. I would submit to the ACO FAA Atlanta office my own panel design of a five inch hole and backup plate with my own drawn up and made inspection plate or maybe even a four inch diameter inspection plate and backup plate.. I would propose to the FAA ACO a smaller flush panel would be a less compromise to the panels structural integrity and wing aerodynamics effectiveness if say a panel fell off in the future. Contact the Atlanta ACO office for your own design for a smaller panel is my suggestion. The FAA ACO is just setting there waiting for questions and their help in complying with your aviation structural questions and they can approve a inspection panel of your own alternative design. Smaller less wing structure compromise is my suggestion. Nice video. I always if I am in an older wing suggest zinc chromate while your there. I have seen old zinc chromate coated wings way over fifty years old and they look like new compared to the alodine wing skins and spars. I have seen the alodine wing skins and ribs where corrosion is so bad you can put your finger or a small common screw driver with just a small push on the ribs, spars, or skins that are almost gone and you go right through the corrosion.

What is the positioning measurements to place the hole? Is there a template for that?

[@billlo1701]

I'd like to buy a template. Please let me know how to make the transaction.

[@damonsolomon6436]

Hello, I am interest in the template. Do you have any available for purchase?

[@jamieb1890]

Have you decided on making templates . I will commit to purchasing one.

Hi. I just sent off a batch to a machine shop. I'll post a link when they are done.

[@justinbritten4476]

Do you still have any templates left?

I have looked at the ad and I don't see any dimensions. What would you have to do to design your own access doors for a certified aircraft and be able to use it? 4313 only shows you the minimum and maximum spacing and doesn't say how far to put rivets or screw holes apart on a access door. I hope you'll answer this as being in an instructor you'd be able to tell me what the process would be to be able to do this. I realize this is an old video but I hope you're still monitoring it thanks for the video

[@frankprio4490]

Are the templates still available?

[@1donagin]

I probably have one somewhere. Find me at aviation.siu.edu, and you can email me from there.
