 |
|
| Quote: | This is the reason why the instructions make a point of
not removing any bid/epoxy around the hole on the
underside, in the event the pip pin ball should not
open on the underside of the new layup, but instead buy
a longer pip pin. Removing bid/epoxy here would
defeat that secondary retention function of the mod.

I am going to disagree with this. I think this requirement
to "buy a bigger pip-pin" is unreasonable.
Firstly, the amount of bid/resin required to be removed to
get the pip pin to release its balls is tiny - see how big
the balls are ! Maybe a ring of 25 thou of resin/bid would
need to be removed.
Secondly I understand that the pip pin BLS4R17N is
somewhat out of fashion and that it and BLS4R07N (much
shorter) are the only ones readily available.
BLS4R17N is a 1 3/4 inch pip pin. There are 2 inch pip
pins available in a different style but with much larger
heads.
The other factor is that the BLS4R17N are about £50 each
from E(2004), so the Mod 73 fix is a few quid in resin and
maybe an extra £100 plus VAT if a bigger pip pin is
required (if they can find any).
It may be that E(2004) can be persuaded to charge only
cost price for the longer pip pins (around £20 - £25
maybe). This problem is after all a design problem.
Hunkering down down to avoid all the flack that will
probably come my way.

Or, for those of us that don't take off the tailplanes (except now every 10
hours) a bolt and a nut (or wing nut and securing ring)?!

If there is an issue with the cost of replacement pip-pins perhaps I can help. McMaster-Carr ( http://www.mcmaster.com/ ) on this side of the pond has of ball lock pins in a wide variety of styles, materials, sizes, mechanisms, etc. It appears that there are a number of pins that would work and are at prices much less than the 50 UKP Go to the web site and search on "ball lock pins" and see what works for new pins. Then let me know how many and I'll see if I can work up a deal on pins at a much better price. Understand, I don't want to take business from E'04, I'd just like to do what I can to reduce the financial impact of these mandatory mods.
Good building and great flying,

Richard,
Mea culpa. Wrong company. I had to go back and check my e-mails for the right company. The manufacturer of the pins is Carr-Lane and they are purchased through a company in Fort Worth called RMP Industrial Supply. I purchased a number of spare pins from them back in January. They were identical to the pieces provided by Europa. The price was USD16.25 each. And this was considered a "custom" length.
I will forward a copy of the e-mail from RMP.
It is possible that I could get further reduced price if the order were large enough.
I'll see if I can find the web page from which I located the supplier. If I can, I'll pass it along as well.
Good building and great flying,
Bob Borger

This is a great message thank you.
I have actually checked the McMaster site and they don't
seem to have a pip pin equivalent to BLS4R17N.
I could of course be going blind/stupid 
My requirement is for a pin with a button which is no
wider at the top than the existing pip pin - around 3/8
inch - as I have a narrow threaded brass sleeve between
the skin and the TP4 which has a threaded cover to it to
keep the rain out. I have no ring in the pip-pin. I have a
tool (a bit of bent wire), which just fits between the
brass and the pip pin to allow entry to the hole in the
pip pin for removal. It is a bit tight and a pip pin with
a 1/2 inch head would not work, nor any of the t-handled
pip pins.
And of course it has to be a locking pip-pin with a button.
Maybe McMaster have some other pip pins which are not
shown on the web site; or maybe I am just blind and
missing the obvious !
TIA
Richard
