Therefore what I am looking for is as follows:-
1) play limits allowed on each blade.
2) can anything be done by me to improve the play.
No Play limits were ever published by ARPLAST. However, unlike many other
VP props, this play will only disappear when the propeller is rotating due
centripetal force. ( It is a bit the same on large fan turbine engines(eg
RB211) which when rotating slowly in the wind make a terrible clattering
noise as the fan blades slop loosely in their mounts.) In other words it is
absolutely normal for there to be a fair amount of play at the tips of an
ARPLAST. In my experience with this prop the most likely cause of
'excessive' play is corrosion of the root thrust bearings. This can only be
checked by dismantling the prop casing. This is also the only way that the
working parts of the prop can be checked and lubricated. I ordinarily do
this on an annual basis. As far as I am aware ARPLAST never issued any
maintenance instructions with their props. All I will say is that ARPLAST
product support is virtually nonexistent.
3) any advice on getting the pv50 overhauled if required.
I am not sure where you are, although I assume from your address that you
are in Italy. Unfortunately if this is the case I cannot help with any
suggestions as I do not know your local regulations or procedures. What I
can say, is that all that I know about them, is what I have learned by
working on them and learning the hard and sometimes expensive way.
The ARPLAST PV50 prop is basically a good piece of equipment when it is
properly set up and maintained and will provide reasonable serviceability.
It is however difficult to set up accurately and maintenance is largely down
to you with virtually no guidance from the manufacturer. Though I am
unaware of the demise of the company I cannot say that it surprises me if
they are in trouble. By the way if you do manage to get them to answer the
phone you MUST speak French.

Subject: Europa-List: Arplast, closing down and PV50 support
Hi fellow PV50 owners (and owners of other Arplast props)
Has anyone else heard that apparently Arplast are closing down due to
product litigation against them.
I am going to try to contact them for support on my prop next week. However
a view of their website has an Adeiu Arplast press release on it. I bounced
it off a French speaker I know on another forum and apparently it is very
direct in its statements towards the French appeals court, that allegedly
over ruled product laws and aviation expert witnesses in the award of
unspecified compensations. Obviously only their side of the story is
displayed.
Therefore I am wondering if anyone has more details on this? To bring
balanced information to light. But also are there any places I could go for
advice and support on the prop.
I have seemingly excessive play in the tips of 2 blades. The third has a
small amount of play but isn't concerning. The documentation available on
the PV50 is pitiful and therefore I have no way of knowing the play limits
allowed, or if anything can be done to address the play.
Therefore what I am looking for is as follows:-
1) play limits allowed on each blade
2) can anything be done by me to improve the play
3) any advice on getting the pv50 overhauled if required.
Thanks
Jon
