14 Hantone HillOurs is mounted on the underside of the fuselage about
12" forward of the tailspring attachment bolt.
It is a small sharksfin design from Spruce and we stuck a circular
groundplane (made from bacofoil) to the inside of the fuselage.
The only downside is the length of the coax cable to the transonder unit
itself. Anything over 6 feet requires a beefed up coax cable (cant
remember the spec). If you buy it from specialist suppliers it is darned
expensive (and about 10mm in diameter). I seem to recall we found
something similar at much less cost from Tandy- bit it was 10 years ago.
Alternatively save some money and shorten the distance to the aerial
(ie: move it closer to the cockpit) - unless you are planning to have
kids !!!!!
Remember that unlike a comms radio a transponder transmits continuously
so the exposure to radiation is greater.

Here's a teaser to get us away from the trauma of mod 73,
Where's the best place to site the transponder antenna on a classic
monowheel.
Thanking you all,
John Price.

Since I bought my Europa classic already flying can anyone advise if
there is a quick way of finding out if Mod 10672 has been incorporated.
This may save a lot of problems.

I understand from Francis Donaldson that the incorporation of Mod
73 will not remove the requirement for the recurring inspection of the
tail called for in Flight Safety Bulletin FSB-006. He has sent me a
copy of issue 3; I have converted this to PDF format which has brought
it down to 387 kB, which should come through as an attachment on the
List. I apologise to those with dial-up, but I believe this is
important because I also understand from Francis that FSB-006 Issue 3
will not now be posted on the PFA website until next week.
I'm awaiting an amended copy of the covering letter sent out by
the PFA, which I will also post on this List, which should make it clear
that further inspection of the rear wing attachment is not required if
it passed the criteria set out in FSB-007. This applies to classic
Europas only, and Andy will be carrying out a trial modification to
install a longer pin together with a washer and nut outboard of the root
rib which will allow the aircraft that failed 007 to fly, and also
improve the integrity of the attachment for all classic aircraft. The
PFA anxious not to compromise the integrity of the root rib in this
area, so a hole will have to be cut in the lower skin surface to
incorporate this mod.
Regards
Mike will

Hi Mike
Do you know from the PFA if carrying out Mod 73 will remove the
requirement for the recurring 10 hour inspection of the tail end?
Regards
Pete

To all Listers
Francis Donaldson, Chief Engineer of the UK Popular Flying
Association has asked me to give maximum publicity to the attached
leaflet for Mod 73 covering tailplane retention. It will be available
on the PFA website tomorrow, and copies have been put in the post today
to all UK owners of flying aircraft, together with a covering letter and
revised FSB 006 at issue 3.
The good news is that compliance (for UK owners) is required
within the next ten flying hours or before the next permit renewal,
whichever is earlier, rather than "before next flight".
There are three steps:
1. Elongation of the pip-pin holes in the torque tube.
2. Modification of the underside of the tailplane by
constructing a reinforced pip-pin recess, except for tailplanes that are
pre-moulded or fitted with Europa Club Standard Mod 10672. Note that
10672 is not capable of being retrofitted.
3. Placards on the top surface of each tailplane warning of
the need to ensure correct engagement of both tab drive pin and pip pin
before flight, and on the root rib of each tailplane to certify that Mod
73 has been complied with.
Fly safely
Mike
