Have a look at the pressure being applied to the Flap actuator cross
tube during retraction.
I had the same problem and needed to reduce the tube length about 1/4
inch on each side.
As the flaps extend they travel inwards and there is a potential for
them to foul and make it dificult to finish the gear up cycle. With load
on the wings (slight ) extra diheadral is there so I applied an upload
about mid span before I could find what was happening.

Subject: Europa-List: Mono-wheel gear retraction
After being installed for seven years and about 400 flight hours, I am
unable to fully retract my landing gear after take-off.
Retraction commences easily enough but resistance rapidly builds and
near the end of the stroke resistance builds to a point where I end up
with max effort about three mm short of the uplock shoulder. This
difficulty has been growing over a period of time--but in the past
overcome by pushing harder. Gear extension is easy with no problems.
Is this simply a bungee problem? Have others experienced a bungee age
problem where the bungee had to be replaced? If so, how does one attack
the replacement procedule? Would a slightly thicker bungee be better?
Looks like the job will be quite involved.
Or, if the bungee should still be good, could there be some mechanical
or misalignment problem?

Hi Bob
Sounds like the bungee gone soft. I replaced mine at 300 hours when on
the
annual inspection it was impossible to get the gear up with the
aeroplane
jacked. On a Classic the job involved removing the exhaust and the
stainless centre firewall. After that it was straight forward and took
less
than an hour. Using the standard Europa supplied bungee worked well for
me.

Hi Folks,
Looking out of the window now it seems unlikely, but the forecast for
tomorrow is pretty good. So how about a DOTH?.
There is a voucher for Conington ( Peterborough) in Pilot - it is
pretty central and has 2 hard runways. Food should be available, tho'
I've never been there, so don't know how good it is. 1200ish as usual.
Cheers, Paddy

It could be something as simple as lubrication. We had a similar problem
(our A/C has been flying about 5yrs).
We raised the plane on a hoist (suspended from engine mounts) and
removed wheel and removed/ cleaned rubber block and shock absorbers. We
found there was considerable stiffness in the bearings on the landing
frame. These were freed by lubricating with teflon spray/ light oil and
the U/C cycled a couple of dozen times to work the lube in. We also
replaced the rubber block.
The gate through which the operating lever protrudes also needs a light
greasing (eg: vaseline).
This has pretty much cured the problem so there is currently no need to
tighten up the bungee cord. If this does become necessary it might be
easier just to add a couple of lengths of luggage cord using the hook
ends to attach to the landing frame and bar on the swinging arm. This
could be accessed from the underside.
Replacing the original cord is almost certainly an engine removal (and
firewall) job.
Hope this helps resolve your problem.

Hi! Paul
My reserve tank holds 2.25 Imp Gallons so I guess that with the a/c
level that should be approx. the ammount you are looking for? Not
forgetting the unuseable ammount in your system.

Subject: Trigear Trailer for Sale and ZAON MRX
Having just taken-up the offer of hangarage at Old Sarum, my converted
caravan trailer is for sale. No beauty, but highly practical and well
insulated, with wing cradles and electric winch. Your for circa St600.
Contact me if interested off-forum at freefolk@screaming.net or
01425-653353.
Ian asked for my comments on the Zaon MRX PCAS. I wouldn't be without
it, although the lack of mode C on so many aircraft in the UK is quite
alarming. However, awareness of this shortcoming hopefully improves the
quality of my visual scan, which further increases when the MRX starts
shouting! I am saddened that none of the European aviation authorities
saw fit to consider TIS uplink when mandating Mode S. Banging on how
mode S was necessary for aviation safety, and then not including the one
item that might save us in uncontrolled airspace (and convince us to
spend the St2000) beggared belief.

Our tank takes about 2.5-2.7 US gallons per side before getting to the
hump, so you can expect to put in about 9.5 liters before the fuel
starts crossing over the hump into the main (port) side of the tank.

Hi Bob! I had a similar problem and resolved it by replacing the bungee with
same diameter but adding 1 more wrap to the schedule. I believe the drawing
shows 6 or 6-1/2 turns, just add one more complete wrap and that should fix
it. Replacing the bungee is a bitch but if you use wedges between the cord
and the firewall to jam the wraps on the upper cross member it will be
easier. Hope this helps!

Willie, It sounds from your replies that top of instrument panel gives OK
results, but I wonder whether the fuselage top between your doors may give
even better results, as I can imagine that pilot and passenger will blank
some satellites for a panel aerial in some situations. Everyone I have flown
with on the trips I have done in Italy have lost GPS signal at some point,
but I never did. I had tended to put this down to superior performance of my
Garmin 295 as opposed to most people's Skymaps, but it may be because I have
my aerial above head level. The cable supplied by Garmin and by Blue
Mountain is plenty long enough to reach there, and otherwise gets coiled up
behind the panel where it could possibly be subject to electronic
interference. Regards, David

Thanks, David and everyone. Presumably, as well as avoiding the
shielding effect of the crew, antenna height relative to the engine
and the metalwork in the panel itself would help comms with
satellites close to the horizon.
On our last French trip in October, (Paddy Clarke, Alasdair Milne,
myself) we all lost GPS signal at various times as well. In addition,
my "Old Faithful" 295 died peacefully (so peacefully that there was
only a frozen display with no explicit warning that it was
meaningless - charming).
Cheers

| Subject: | GPS antennae siting |
With the GPS constellation's orbits inclined at 55 degrees from the equator
those of us in the northern hemisphere will find the satellites generally
toward the southern sky. This is much more significant in northern Europe
(London 51 29' N, Paris 48 49' N, for example) where the satellites are
near (or below) the southern horizon most of the time. I suspect that
eastbound and westbound flights will get better reception than northbound
and southbound flights if the antenna is within the panel since both the
crew and the engine will tend to shadow the antenna.
Can anyone confirm or refute this hypothesis from in-flight experience?
