| Subject: | DOOR/GAS STRUT DAMAGE |
--> Europa-List message posted by: "Peter Davis" <peterdavis@ntlworld.com>
Hi Bob,
I had to rebuild the door lug when mine broke. When removing the remains of
the old one I realised that the metal insert forming the lug was too small
for the job and, in fact, the hole for the gas strut ball joint had missed
it - most of the lug being made up with fibre and filler and apparently only
stuck onto the surface of the door inner moulding.
I made another lug in steel that is bonded through the inner door moulding
and meets the outer moulding as well. Makes a good strong point. Repair is
quite easy but infuriating as you will be thinking "If only it was made
properly in the first place .............." Definitely no point in replacing
the door. It might just happen again.
I must now get on with the other door lug which has gone the same way. A
good method of starting the demolition job is taxiing with the door slightly
open but not being held tight enough :-(
Regards,
Peter

Upon opening door, gas strut end fitting broke thru bottom edge of molded
lug on door.
Has anyone else had this problem?
Short of replacing door, how was repair made?

I agree - it sounds like carb icing, but it's strange that the beat was in sympathy!
As a result of a particularly uncomfortable November UK flight, I fitted the Rotax
carb heat kit and have had a silken smooth engine ever since.
Highly recommended...

Hi Jim,
This is one thing I have been considering but have put off 'cos I am not
aware of any reported incidents of carb icing on the Europa. However, guess
who might be the first! :-(
I certainly don't want to find out the hard way and was thinking of blocking
off the cold air intake and replacing the plenum with the original cone
shaped filters for under cowl air intake just to see.

Peter

Pete,
You need the carb heat blocks to prevent any possible buildup of
ice in the carb area. Its "good" life insurance. Cheep at twice the
price.

Just fit the Skydrive carb heaters. They you won't have to worry about
it without reducing the engine power.

I have observed a similar vibration in some occasions just after take-off, when
reducing gas from full power. It happens around 4800 rpm. What I do is to reduce
a bit more and then increase it again if needed. So the vibration disappears.
I do not think it is related with carb icing. I fly in Spain with high temperatures.
My opinion is that it is a kind of resonance related with the engine revolutions
and plane attitude.
Best regards

--> Europa-List message posted by: "paul stewart" <paul-d.stewart@virgin.net>
Neither the europa manual nor the Rotax installation manual appear to tie up with
our engine (914 delivered 2 months ago). The manuals call for the airbox pressure
sensor to be mounted on a backet with the static sensor and 4mm PCV piping
connecting it to a 'T' on the airbox. There is no 'T' on our airbox and the
airbox pressure sensor appears to be perminantly installed directly into the
airbox. Neville knew nothing about it so it would appear that the manufacturer
has modified the engine without altering the installation manual. Anyone know
anything more or different?

Paul,
My 914, delivered about a month ago is the same. Maybe the older engines
have the airbox sensor separate? Anyone out there able to tell us?

The older ones have a separate airbox pressure sensor which is mounted
with the inlet airbox sensor on the firewall.

On the earlier 914 engine the Airbox Pressure Sensor and the Static Pressure
Sensor are mounted on a bracket on the firewall. The Airbox Pressure Sensor
connects to a fitting on the airbox via a rubber tube, with a "water trap"
in the line to the airbox. The "water trap" looks like a fuel filter for a
Volkswagen (maybe it is).

I do the same as Javier; increase power, or increase VP pitch to load the
engine. Always clears the vibration. I think it is back-lash in the
gearbox.

Hi! All.
Just putting my nose in here since I'm very sensitive about Propeller
Harmonics. IMHO there is insufficient effort made to assess the whereabouts
of this phenomenen in the RPM range. I know where mine is because MT
Propellers have produced the necessary analysis resulting in an "avoid
continious range" of 2150 to 2250. It will be different for each prop
type/engine combination but if ignored can have dramatic failure
implications. William does right to get out of the vibration range but I
think it may be the RPM factor that is the real item to avoid not the load?
Just food for thought!

| Subject: | Peel Ply on Root Rib |
--> Europa-List message posted by: "Ronald J. Parigoris" <rparigor@suffolk.lib.ny.us>
Into reinforcement of the root rib/spar.
Manual tells you to "REMOVE PEEL PLY"
To this point I have only seen Peel Ply in Bright Green and there was some White
tapes. I also purchased some 1 and 2 inch white precut tapes.
Well the Peel Ply on the Root Rib looks an awful lot like glass. It does have a
few
red threads in it.
I guess everyone out there except us knows that red threads in a perfect lay-up
means
that there is peel ply in there.
If someone is as foolish as builders of A-265, then they too will be sanding on
the
peel ply.
Finished scuffing the forward rib, and when got to the rear of the root rib, there
was
the smallest of small wrinkles, went at it and sure enough it was in fact peel
ply.
Feel foolish that spent 20 minutes sanding peel ply till discovery. I saw these
perfect 3 red thin threads and just kinda sortta put them in category of thin guide
lines, like on the fuse.
Has everyone removed the peel ply in all 3 areas on each root rib?
Feeling foolish in Kings Park
