A life's (fatal) lesson on how NOT to maintain magnetos

From what I read, two of the magnetos on two different engines were messed up, not just one of them. These planes have a special exemption from most of the FAA regulations under a special "Part" of the U.S. Code of Federal Regulations, which meant that the volunteers were reporting the plane's maintenance to a special supervisor with the FAA in Florida, not through regular FAA channels, and that special supervisor went away for some reason (retired? transferred?) so there was nobody to report to for a long time, so the volunteers let maintenance get lax.
