Does a Cessna 152 have an afterburner?

There is an AD that requires just this
test, BTW.

My Bonanza V35B has such an AD. Every hundred hours, I have to test the
ignition by turning it quickly off and then back to both to verify the
p-lead is intact.

Just about all light aircraft since the AD is on the mag
switch.

The AD for my Bonanza is dated 1977. Are you saying that this ignition
problem exists for aircraft manufactured after that year?

It is a continuing problem. Mag switches wear out and the
engine will "fail safe" to a running condition when the
switch fails "open" circuit. The AD is so that the failed
mag switch will be detected before someone is killed.

Several Ignition switch ADs:
This one addresses burned start contacts in the switch:

So does this one:

This one applies to this discussion:

Lots of these switches are in use. They could end up on newer
airplanes as replacement parts from older stock that hasn't been
checked by the seller. The ADs are listed under "Appliances" and that
section can be long and dry reading while doing an AD search for any
particular airplane. I have seen overlooked ADs on a lot of stuff
listed under that section.

Interesting. Thanks for that.

You can save a lot of time if every part replaced or
installed is listed by make, part number and serial number.
As the FAA gets everything on-line AD searches will become a
matter of automated database searches. But if you don't
keep good records you'll still need to open the hatches and
look at each part.

When buying a plane, open the hatches, the records may say
the AD was complied with, but an inspection often finds it
hasn't.
