For UK europa people wanting do add a special touch to their Christmas
cards, I notice that there is a 16p stamp (which can be combined with an 8p
stamp for 2nd class) that has EUROPA written on it in large letters - with
not much explanation, but presumably something to do with the EU! Regards,

Fred,
This is a really well designed mod. I like the simplicity and the fact that
it is not taking away any usable space. I would hope that the Europa Club
mods people will take this on as a standard mod with PFA approval.

Duncan,Thanks for your input and questions...answers indented below.
reeserve.co.uk>Fred,Nice execution of a good idea.CSA-VLA provides little g
uidance:http://www.easa.eu.int/doc/Agency_Mesures/Certification_Spec/decisi
on_ED_2003_18_RM.pdfSee pdf page 100 (or pages 2-8 and 2-9 at the back.It m
erely advises for "..adequate separation of ...straps to minimise... chafin
g of wearer's neck...." but recommends a maximum separation of 8" and maxi
mum included angle of 60 degrees. I really didn't want to re-invent
the wheel here, so one of the starting points was to not alter the attach p
oint of the shoulder straps...and to secure the "riser" to the same hard po
int used for the straps. If our shoulder straps had had individual bolts to
the hard point(s), I would have maintained them; since they go back to a s
ingle point, that's what this design works from. The key to "minimise...cha
fing of wearer's neck" is the location of where the shoulder straps connect
to the seat belt; in my opinion, there is no cause for concern here.
Was your load testing applied to the straps as fitted to the device in the
aircraft or merely to the device sat on a strong surface? I've done
no testing with this "riser" bolted to the CM. The photo below shows the t
est rig I used. The riser is mounted on a piece of 4 x 10 wood with an angl
ed face, set to duplicate the angle between the back and top of the head re
st. Unseen beneath the strapping are two AN3 bolts which correspond to thos
e bolts which penetrate the hard point on the back of the headrest and flan
k the AN4 bolt which secures the typical shoulder straps; see other photos.
Note that I've substituted 2" wide cargo straps for the standard issue sho
ulder harness straps; since I'm testing this little "riser" and not the sho
ulder harness, I thought this would have no effect. Note also that the stra
ps are clamped beyond the edge of the "flap"; the riser is held in place so
lely by the two AN3 bolts (under the straps). Also visable in the p
hoto is a gauge resting on a loop in the straps with a pressure plate benea
th a 2 x 2 steel tube which receives the force from a 20 ton hydraulic pres
s. The test rig presumes that tension forces on the shoulder straps
will be transmitted to the "riser" at its apex which has a radius of 3/8"..
.so the big question was...Would the "riser" be crushed? Well, I really di
dn't want to destroy it, so I stopped at 1500#; this load was reached incre
mentally...it was not an instantaneous load. Full Disclosure: My bud
dy with the hydraulic press uses this gauge to measure the tongue weight on
trailers he uses w/ his business...he swears that it measures weight in po
unds. However, as you can see in the next photo, the gauge is labeled in ps
i. You can note the size of the pressure plate in relation to the 2 x 2 ste
el tube...it appears to be about 2.5 inches in diameter...which means its a
rea is just under 4.9 sq. in. This then implies (to this non-engineer) that
the force on the straps would be more like 7359# rather than just 1500#. C
ould this be so? Help!
And would it be better to wrap the forward edge of the device around the fr
ont edge of the headrest, to reduce the eccentricity of loading on that cor
ner? thereby maximising the resistant of the front face of the headrest
Though it appears greater in the photos, the front face of the riser is
only about 1/4" back from the face of the head rest...the intersection bet
ween the top and the front faces of the head rest has a radius...I sized th
e "riser" so as to not extend beyond the start of the radius. Personally, I
'm unclear as to what portions of the loads are transmitted to the front fa
ce and what portions are distributed over the top head rest surface. The he
ad rest construction appears to me to be the same on all faces, so I didn't
think aligning the front faces would be significant.
Would prefer to see the guides at the top made as part of (or recessed in t
o) the moulding, with broad rounded edges. The beauty of homebuilt a
ircraft is the latitude (at least here in the US) it gives to allow for per
sonal preferences. The design I developed was intended to both satisfy the
functional requirement and be sympathetic to the tapered forms of the head
rests...guess I could live with the "ears"! Ron Pagoris has suggeste
d I do some load tests of side loads such as those which might be encounter
ed in a ground loop...so notwithstanding the pixs of these puppies on my CM
, I guess it's back to the lab for a bit.FredA194

Interesting thought Karl...I'd be happy to assist in any way if someone
in UK wants to pursue this.

| Subject: | Rotax 912 run on |
We have of late been experiencing a run on with the engine after switching
off!
The only way we have been able to shut down has been by turning off the
fuel.
It does not do it evrytime, however the instances are becoming more
frequent, I have only subscribed to the list for just over a year and dont
recall any other instances?
However if there are any ideas or suggestions I would be gratefull?

Hi,
We used the typical mag switch from Aircraft Spruce, and now with 500
hours on it, we have had the occasion when it will not shut off the
engine. It seems to be dirty contacts in the switch, which is supposed
to short both mag wires to ground. Moving the switch to on, then back
to off eventually cures the problem.

Hi Dave,
I had this on my 914 and it turned out to be a partially broken mag
wire. It was right at the crimp connector. The wire on those modules
isn't too good.

David,
Most likely, one (or both) mags are not being properly shorted to ground when switched
off. Do you get a proper mag check? That is, do you get a RPM drop when
you check Mag A and Mag B individually on your run up mag checks? If you
do not, then one of the mags has a bad ground wire. If you do get a proper RPM
drop on both Mags, then your switch does not properly ground one or both mags
when switched off. Check the switch connections in the off position to make
sure both mag wires have continuity to ground.
Let us know what you find.
Great flying,
Bob Borger

Hello David
"We have of late been experiencing a run on with the engine after
switching off! It does not do it evrytime, however the instances are
becoming more frequent"
As mentioned, check switch, connections and wires first. If still doing
it, I have heard if you get ignition modules hot, the first symptom is you
can not turn off motor. Wrong time of year to first manifest??
On 914 anyway, you can swap ignition modules for a test, but it is not
recommended to leave it that way, may help a bit in narrowing down
problem.

David,
I just went through this last summer and as Paul said it's probably at
the mags. The wire coming out of them is very cheep and needs a pig
tail of quality tefzel (Not sure of that spelling) wire. We then
soldered the ground wires direct to the pigtails and the problem has
never come back. Make sure you tie wrap the pigtails and put some
shrink tubing at the solder joint. Vibration is your enemy right at the
mag. A partially broken wire gave me fits until this list told me to
look there.

I would put my money on this as the cause! I also have seen this and talked
to 912 and 914 drivers with the same. Tie all those wires tight after
fixing!
