Seems our Pmag issues were pretty much identical then.

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.

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.

I change them every 100 hours at $40 a set..

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?? -- 2/8/2007 -- 2/8/2007 ________________________________ Message 3 _____________________________________ Time: 06:58:08 AM PST US From: "Mike" Subject: RE: Engines-List: Engine Running Rough 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.

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. -- 2/8/2007 ________________________________ Message 4 _____________________________________ Time: 09:13:44 AM PST US From: "Noel Loveys" Subject: RE: Engines-List: Engine Running Rough Electronics techs call then Intermittent problems....very hard to diagnose.
