| Subject: | Re: Stern post access panel |
My mono, classic with the XS Tailwheel spring, has now got over 2,100 hours on
it over the last 17 years and I have never found the need for any other access
for maintenance than is afforded by the standard access panel under the tailplane
which I used to install the Tailwheel spring when it first came out.

which must strengthen in back up a bit?

Hi Tony,
My first post wasn't very well worded. The stern post is, as you say,
immensely strong and shouldn't give cause for worry.
My concern is for the proximity of a large diameter hole so close to the
tailwheel spring mounting point. The tailwheel loads on a mono will be
dissipated upwards through the sternpost. By placing the inspection hole
immediately above it in the load path, there is a possibility of failure
should the aircraft experience a ground loop or particularly heavy
tail-down landing. The farther away this hole is placed from the spring,
and the smaller the diameter of the hole, the less likelihood of a
problem. The position is of course, dictated by the alignment of the
pitch push-rod (as per O.P.'s post). The trig-gear does not have this
problem as it has no tail spring.

is reduxed in, well I would think it should make no difference as it is such
a strong member. I for example am building a Classic, but have incorporated a
sternpost. My tail spring sits quite tightly in the sternpost, and mine is a mono
wheel, actually a taildragger. Id like to know if anyone else sees this as
an issue?

a vent from the D panel to the stern post. So my question is, is there a mod
for this install on G-IAN

| Subject: | Re: firewall mountings and penetrations |
A few suggestions:
1. Make access panels in the firewall above the footwell. Layer the panel
with stainless on the engine side. The panel is absolutely invaluable to
reach and work on the inside of the panel module without having to
remove it from aircraft.
2. Plan ahead that there will be times where removal of the instrument
panel will necessary. fixed wires running through to the engine area will
preclude that. The safest, most reasonable approach is to use multipin,
metal shell circular amphenol connectors

Hi Clive,
Unfortunately y Europa was built before the proliferation of digital
cameras and the photo I sent you was scanned from a print taken from a
35mm camera.
You are right though, I had to think about the brake cylinder, but as
you can see I made a small bullet type fairing shape using the same foam
block and glass method used for the tunnel sides. Otherwise both sides
were the same.
Regards,
Martin
