Apologies for not replying earlier to your reply of 19/08. Andy Draper has
had a sudden attack of needing to tidy up some of the paperwork. The result
is a new Standard Mod (for the Andair fuel selector) and the Fuel Flow SM
updated for the FT-60 (Red cube) flow sensor. Not much use if you know what
you are doing but it makes the upgrades legal in the UK.
I think it is worth saying that on Mod 77 I inherited a partially
undocumented mess. Graham sold Mod 77 to David Stanbridge who then
announced it as available. The fact that nobody at Europa had ever seen one
(never mind built one) seems to have escaped David's notice.
I think the bill of materials [BOM] used when you got your parts was the old
one. I have checked with Europa and they are now using the new one included
in the document.
>> One very important thing: I had already installed a vent opening in the
sternpost <<
Yes as I have on G-IANI. The pictures were taken on G-IRON which was being
rebuilt so the hole was not needed. I will add a reference to adding this
hole for a retro fit. If time permits I may do Mod 77 on G-IANI this winter
and can photograph the work.
>> Oh and there is no mention in the document about the connection of the
rudder end of the push rod.<<.
There is (see section 3.7) but it is easy to miss
>>I received an EUR001 safety washer for it, the manual says to attach it
similar as the other end, but as the rudder end has two lips instead of one
the eye-bolt can't go anywhere anyway. I just put some AN416L washers on
both ends between the lips.<<
You are right I will try and make this clearer.
>>I would also like to see a different way to attach the push rod to the
rudder, as it is very difficult to tighten the nut on the AN4-bolt via the
rudder gap. Maybe just a bolt with a cotter pin through it would do?
Anyway, you can't access it with a normal socket, and with a spanner the
clearance is not enough to make a sufficient turn. I ended up using two
ratcheting spanners but just one "click" is all I can get, so it takes hours
to tighten the nut. (And no, you can't connect the push rod to the rudder
first, as there is no way you can handle two spanners through the hatch to
tighten the other end afterwards (I can get only one hand in it at the same
time). Now I think of it: Maybe an anchor nut on that metal plate would make
things easier, instead of the nut and bolt.<<
I think I prefer the idea of using an anchor nut on the CS33.
>>Is there a reason why this is from steel instead of aluminium? We used
aluminium for all the other controls in the ship (it looks like the aileron
push rod is the same diameter but then in aluminium), so why has this one to
be from heavy steel?<<
I think it is just history and people being conservative. It is 100 grams
heavier than the Al tube of this length. The forces on this rod are
considerably higher than on the aileron rod and a structural engineer will
need to convince the LAA that the Al tube would not bend.
We make progress slowly
