Blown Slick Mag Coil

Post by Rich »

Recently one of our fellow owners was AOG with what turned out to be a blown coil in the left mag. This is not something that gives warning indication during the routine 500-hour IRAN. Aircraft Magneto Service had done the most recent IRAN about 250 hours prior and repaired and rechecked the mag under warranty at no charge. :thumbsup:

That’s reassuring. My mags are getting a 500 hr IRAN this week. What did the plane/pilot experience when the coil blew? Thanks.

It was freaky, a rather slow failure. Intermittent roughness slowly getting worse over a period of hours. Mag would check on runup, get weird in flight. Finally it was really raggedy on runup while away from home. Strangely the mag never actually went completely dead, so it wasn’t a total blowout.
