In the past I have many times agreed with your facts, but I have

disagreed with your way of expressing them. On this occasion I am
with
you all the way.

Let's hope the first aeroplane to crash because of lead-free solder
has
only Brussels diplomats and anti-lead campaigners on board.

As far as I know, at this point in time, the avionics industry still
has
an
exemption from having to use the stuff. Now I wonder why that could be
... ?

They may be exempt, but what might they do when they can't get the
proper stuff any more because no manufacturer can afford to run two
production lines for the same product simultaneously and daren't risk
getting them muddled?

1) Set up special production lines.
2) Stop making avionics.
3) Change the rules and use lead-free.

There are no plans at the moment, from what I can gather, for
manufacturers
to stop producing leaded solder, nor for distributors to drop it. There is
much 'legacy' equipment out there, which is manufactured in leaded solder,
and should not, as a consequence, be repaired using lead-free solder,
according to published wisdom from those who should know. There is no
legal
requirement to use lead-free for the purposes of effecting such repairs.
As
well as avionics, there are a number of other exemptions in important
fields
such as medical equipment, and some military areas. Again, I wonder why
that
could be ... ? As far as I understand it, the American military will not
tolerate the stuff being used in any of their equipment. How eminently
sensible of them. Pity we haven't got the same courage of our convictions
to
stand up to the green mist brigade on this side of the pond ...

Maybe after the Eurofighter fleet is grounded because of avionics
failures linked to LF solder?

Hope they don't use it to solder them Airbuses together


So do I, my friend, as I am about to get on one for the first time in
October. All of my previous cross-pond jaunts have been in properly built
747s, which have a proper yoke for the driver to hang on to, and
'automatics' that can be switched off. There's something fundamentally wrong
about a plane that has to be flown with a left-handed joystick, and which
employs a robot driver hidden away somewhere, which believes it knows more
about how to fly a plane, than the human guy and his chum in the co-seat,
who have 40 years flying experience between them ... :-\
