Subject: | FW: A query re LG 01 |
Classic Europa serial 76 (G-BXIJ) was completed in 1997, and subsequently
sold to Robin James; the original owner, who built the aircraft, has since
died.
The engine has recently been removed from this aircraft to have its sprag
clutch changed. Whilst the engine was out - the work was done by Adrian
Lloyd at Shobdon - it was noted that the top horizontal fore and aft tubes
of the landing gear mounting frame (LG 01) have reinforcement sleeves
fitted. These sleeves, which run the full length of the LG 01 top tubes, are
not secured to the outer tube at the front, but are very neatly welded at
the back end.
Robin, who is a professional engineer, reckons that the sleeves are 4130
material, and his calculations suggest that there would have been a 24/1000
clearance between the outer and inner tubes when fitted.
Does any early classic builder - or even you, Nev - have any recall as to
why reinforcement tubes might have been fitted to this or other early model
LG 01's? Andy has suggested that the builder might have made a mess of
drilling the holes for the attachment bolts in the top tube, but Adrian has
looked carefully in that area and confirms that this does not look to be the
case.
Any comments will be gratefully received.

Subject: | FW: A query re LG 01 |
Hi! David.
I'm just a little mystified about "Fore and Aft" description.
For the record I also fitted thick walled close fitting aircraft quality
tubes and bonded with redux into the LG01 frame adjacent to the
"connectors of the engine mount frame" extended aft to the first bolt
attachment of the tunnel top.
I did it for no reason other than a "gut feeling" of "belt and braces"
addition.
It seems like you are saying that yours are extended right through and
welded into position....good fix I'd say ! Except I'd pressure some
runny Redux down the annulus between the tubes from the front.
Regards
Bob Harrison G-PTAG

Subject: | oil thermostat vs cowl flap |
Hi Remi
Thanks for coming back to me. If you have any photos or diagrams showing
your setup I would be grateful. In particular how you arrange the
linkage and control of the flap would be interesting.
Probably best to communicate direct to me at nwcmc@tiscali.co.uk.
Regards
Nigel Charles

Subject: Europa-List: oil thermostat vs cowl flap
Hello Nigel,
Thank you for your comments on my inlet cowl flap you saw in Vichy. Some
additional information: the lower position is to be used on the ground
only. The flap must be raised to the neutral position just before
take-off. If you don=92t, it is very difficult to actuate in flight due
to
the huge aerodynamic forces. From neutral to the upper position, it can
be adjusted at will in flight to control the CHT and oil temperatures:
especially useful in winter.
Regards

When I was at Vichy this year I met one of our French owners (sorry I
forgot his name). He has a very clever inlet cowl flap. It is part of
the lower cowl in front of the radiators and has a hinge at the rear of
it. In very hot weather it is lowered below the normal cowl allowing
more cooling air in. In cold weather it is raised impeding airflow to
the radiators. This is all controlled from the cockpit so that inflight
adjustments can be made.

Heavy engines (like the Subaru) had to have the top arms reinforced.
This was done with 3/16" wall thickness material.
Sleeving on the inside takes a lot more material than you might think to
make any appreciable difference to the bending strength of the tube.
Sleeving on the outside is of course different matter.
There is an 'MPD' requiring inspection of these tubes, where heavier
engines are fitted. Although it is the composite that the arms are
bolted to that is equally "lacking".

Hi All,
I am currently on the road in Northern Florida and I have a small problem that
I need to deal with. The thread has stripped on the nipple that holds the EGT
probe in on the rear exhaust pipe (914 Turbo) and its letting exhaust gas out.
My current thought is to remove it, try and find a stainless steel bolt to screw
into the fitting on the exhaust pipe to blank it off. So, the question to the
forum is, does any one know the size and pitch of the thread on on the exhaust
pipe port ?
Next problem..... Because Ican't access the forum to read mail while I am on the
road I NEED YOUR REPLY TO GO TO paul_mcallister@hotmail.com, NOT TO THE FORUM.
Thanks, Paul

To Those That Have Sanded Before Me...
Would anyone like to share a helpful hint on applying filler smoothly to a
leading edge? The Anti Servo Tab is giving me fits today....
Thanks in advance.

Hi Brian,
Don't think there is a simple trick for this.
Basically, apply the filler generously, and sand back later. Honestly, it was difficult,
and i was happy to get professional help.
Kind regards

Hi Brian,
I just put it on thick, sometimes using my fingers... gloved of course.
Let your large sanding block with 80 grit in diagonal motion one way,
then back the other take it back down to the shape of the leading edge.
Get with anyone local thats built a glass plane. I did with a local
long EZ builder and his advice or on hands experience was priceless.
Regards,
Jeff
