Thanks for the clarification Mike.
Seems our Pmag issues were pretty much identical then.

Frank.
The airplane engine didn't quit. The CHT's and EGT's went off the chart
and the engine couldn't make enough power to maintain altitude. At the
time the plane was in the high mountains in east AZ.

They may not know for absolute sure but there is a failure mode they
found that allows the unit with certain software versions to lose its
timing. There is a sevice bulletin on the Emag website about it.
It certainly makes sense and fits the description of the issues on the
downed airplane. I also had the same issues but my engine did not
actually quit.

Subject: RE: Engines-List: Auto plugs
One of th4 things I've never tried to do is replace the plugs on a plane
with anything other than the same type of plugs that came off.
Generally we used to inspect and clean the plugs every 50 hr.
(commercial) and return them to service. At better than $50.00 a pop we
weren't too interested in swapping plugs at the drop of a hat. the one
rule we did use was if we dropped a plug, the never happened, the second
drop would be in the oval filing cabinet.
Good stuff but not why I'm replying... As I said I never replaced a plug
with anything but the same type. so I am wondering if the thread and
reach of an automotive plug will even fit into the hole??

Well, when we ran the airplane on the side of the road for 30 minutes we
couldn't duplicate the problem, everything was working great. So we
flew it out thinking it was fuel ice, the airplane pressed on to
Phoenix. It wasn't until the third flight that it happened again (as
explained to me). Just because you can't duplicate a failure on the
bench doesn't mean it didn't happen. One thing to always remember with
certified stuff, if it fails there is an AD in your future. We are the
AD process in the experimental world. Turn key operators need not apply.

Steve -
I must disagree. I called EMagAir last week to ask some unrelated
questions
about the EMag and PMag that are hanging on my engine. After answering
my
questions (harness related) and discussing the background, I asked Brad
to
tell me what he knew about this incident. He explained that they had
examined and tested the suspect units and could not duplicate the
failure on
the test stand. If I understood him correctly, rather than send the
suspect
units back to the owner, he kept them for further testing and returned
new
PMags.
Remember the folks over at P-mag don't like bad news. Don marry a
product, help make it better.
