Key Locks -- Part II

I was trying to remember just what that AD was about. I remember
reading it
a couple years ago, but do not know why. Wasn't there something in
the AD
about the switch malfunctioning and actually leaving one or both mags
hot
when the switch was turned to off in addition to the key comeing out?
Seems
like I also remember an inspection and lubrication requirement.

Maybe I was just dreaming.


You remembered pretty accurately. The switch test involved turning
off the engine via the mags and making sure they both grounded. If
not, it's replacement time. If the key came out in any position other
than "off", it's also replacement time.

On Sunday I was doing a BFR in a rental. During the engine out
glide, the instructor reached over and switched the mags off and pulled
the key out. He thought it would rattle/distract me. I had a really
good laugh when he couldn't get it back in. He was starting to look
kind of worried passing through 1000 AGL.
