0700 Morning routine. I had a discussion
with Andre TURENNE about the IFEN system that he has worked on
for much of his time here. He is reviewing the paperwork
involved in its certification. He advised that there has
been no indication whatsoever of an actual problem in the
overall system, or in any aircraft in which it has been
installed. The reason for shutting it down was that the
system was hooked up to the fuse panel by four fuses that were
independent of the bus shutdown system. The pilots had not
been informed that they could not shut it down except by pulling
these four circuit breakers. What was required was an
automatic relay system that shut down the four breakers when one
of the bus systems was turned off. But it appears that
this was just an oversight on the part of the engineers because
it was deemed a non-essential piece of equipment, equivalent to
a coffee pot or magazine. TSB took the attitude that if it
entered the cockpit wiring system, then it should be an
essential piece of equipment. There was also another
problem with a high voltage wire in proximity to other wires,
but that was an installation fault that could easily be
adjusted. But there is no history of faults with this
system. Other systems do have a history, including shocks
at the seats and others. However, due to the leak of
information, the IFEN system suffered in the public’s eye and
put all of the faults onto this one system. So, Swissair
was forced to pull the system. Andre believes that the
source of the leak was Greg FIFE of the NTSB. He had
access to the material as he was on the committees. He
lives in Washington and it was released the day after he
returned home. The details were too precise and accurate
to be anyone outside of the committee, and his wife is involved
in the US media. As well, he is a media conscious type.
However, he has no proof. But he has shut down the
committee after the release and refused to work any further with
FIFE.
