Mike,
You are quite right in realising that Mod 73 does not need to be done on an
aeroplane if you have a tube or bar of the correct diameter to fit inside TP
6 while the lay up is being done. This could be an uninstalled torque tube
or some other material that is a proper fit. A note of caution: I believe
early and late torque tubes were supplied with slightly differing diameters.
The Europa Club Committee have been considering setting up Mod centres where
the necessary materials and expertise will be available, together with an
inspector to sign off the work, although details have yet to be worked out.
I understand the PFA are considering a separate modification to the wing
rear attachment point.
Regards
Mike

Mike,
Would it not be better for the club to obtain 3 or 4 torque tubes from the
factory (could be just stock tube). We could then do the layups on the
tailplanes in the temperature and humidity controlled comfort of the
workshop.
Is there still a Mod to the wing rear attachment point to come??
regards,
Mike Parkin

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
Europa Club Safety Officer
