Subject: | Re: Tail plane torque tube assembly tips needed |
Thanks Alasdair
My kit is American but the original British paperwork has the serial
numbers 467 and 450 on it and is dated March 98 and March 99 so it is a
very similar vintage.
With the problems some have had with movement around the tube I don't mind
having a snug fitting tube. The 230 pounds for a replacement and freight
half way around the world are also a strong motivator for finding a
solution using the existing parts.
I might try heating a room to 35 degrees C and putting the parts in there
for an hour or two to see if that loosens them up. Another option which I
will follow anyway for enlarging the holes to take a 3/8" pin is to find
someone who is an expert with metalwork and get them to do the job. Even
if I have to pay someone it will be cheaper than buying a new tube and I'll
know the job has been done properly.

Subject: | Rotax 914 Airbox / Fuel Pressure Differential |
This is a question for those who have a 914 up at the front.
With the 914uls the best way to monitor fuel pressure is to monitor the fuel /
airbox differential pressure. I'm looking for a simple and 'tried and tested'
way of doing this. Can anyone recommend a setup for this? I see there are a
variety of dual gauges available and also gauges that do the calculation for
you (via sensors) and just have a single needle showing the differential.
Any input or advice of what other people have done would be welcome.

Graemewhen I initially thought about enlarging for the 3/8=9D
pins, I assumed I=99d just use my trusty drill
pressFORTUNATELY, before doing so, wiser heads prevailed and I
took the assembly to a machine shop where the work was expertly done.
Given that this assembly is a critical component for safe flight,
caution and care are called for to avoid a sloppy fit.

Many thanks to those who sent words of encouragement for yesterday's DOTH to
Le Touquet, despite being unable to join us themselves. It was probably too
short notice for such a trip, and only Adrian and I made it.
Here are two snapshots - to prove that Adrian is no longer a Channel virgin,
and to show the resort delights that await those manage to make it to Le
Touquet. The French air traffic controllers' strike did not appear to have
any effect on us, as Lille responded promptly to our mid-Channel call and
passed us on to Le Touquet at point N - all very friendly and helpful.
I hope that this message will act as a spur to all to support David Joyce's
re-planned fly-out later in the year, which with luck will have good
weather.
Best wishes,
Mike

Subject: DOTH: Le Touquet Trip - 26 May 2016
Following the cancellation of last Saturday's fly-out to Le Touquet because
of poor weather, Adrian Stephens and I did not wish to let our enthusiasm
for the trip fade away, and are planning to take advantage of tomorrow's
much better weather. We shall be setting off tomorrow in Adrian's Europa
G-EUAB from Cambridge, aiming to arrive at Le Touquet around 1200 local
(1000 UTC).
It is some time since anyone called for a fly-out at a drop of the hat
(DOTH), so we thought this would be a good opportunity to encourage other
Europas to head for LFAT tomorrow, 26th May. I cannot recall a previous
DOTH nomination for a foreign field, so perhaps we may establish a first -
apologies for the short notice!
I am copying this to all who had expressed a wish to come last Saturday, in
the hope that they in particular can revive their plans - but all are
welcome.
Best regards,
Mike

Dear All, I am sorry to say that as of 1300BST today, (Friday) tomorrow's
forecast has not changed significantly from last night, except wind now 12
gusting 20kts, more or less cross; fair bit of rain around and RASP showing
if anything lower cloud base with mostly 500-1000 ft over S coast and our
half of the Channel. Gramet is a bit more optimistic, but I have found their
cloudbase predictipns to be appreciably less reliable than RASP. I an sad to
say that it is clearly inappropriate to proceed with the trip this W/E, so
it is now formally CANCELLED. I will look out for a possible date to try
again later in the year.

Phil, I am all for minimising the time you spend eyes down, (having
experienced 5 mid air near misses with 3 probably fatal had I not been
looking out!). From this point of view, I would doubt the value of a
fuel pressure guage, as opposed to a low fuel pressure warning light,
which shines a bright red light at you if pressure falls below a set
level. To this end I sourced an on/off fuel pressure switch set to light
up if pressure fell below 3 psi (as I remember it - but it should be
easy enough to find a pressure well below normal running pressure and
above what will stop you flying). This worked well for me in running my
main tank dry. I found it came on in plenty of time for me to switch to
reserve before the engine coughed. It would also, I guess, work well if
you had a partially clogged filter and needed to switch on pump 2 and
reduce power to limp home, as happened to the company demontrator in
early days. I cannot think of any very good reasons to need a fuel
pressure gauge apart from these instances.

I don=99t often disagree with you David but I think a fuel
pressure gauge is a very useful indicator of impending problems,
including filter blockage and fuel vaporisation. When the red light
comes on it is all too late.

Brian, I bow (to the point of grovelling in fact!) to your infinitely
superior engineering knowledge, but have you in fact found a use for it
practically? A theoretical value is all very well but I have found no
practical value in 14 yrs flying a 914, other than the instances I cite,
and I am entirely persuaded of the value of looking out the front, to
avoid the other b*****rs coming straight at you whilst carefully working
their way along their rows of dials, trying to remember what they should
be saying or said last time they looked! One person's experience does
not a thesis make, but three occasions where a head on collision was
only averted by me turning abruptly whilst the other party cruised
straight on with no sign of having seen me, certainly persuades me of
the value of designing one's panel to be able to spend as much time
looking out as one would devote to it travelling down a busy motorway,
where at least the likely collision candidates are going in the same
direction! Looking at a gauge for impending problems , implies a lot of
eyes down attention
