Maintenance questions

There are ADs against many mags, some of them dealing with
impulse failures. Get the mechanic to check for any that apply to this
mag.
Corrosion and sludging often cause sticky impulse couplings.
Neither are good, especially the corrosion, which can cause spring
breakage and power loss. Mags on infrequently-flown airplanes, or those
mags that haven't been off for a long time, definitely need checking.

All the AD's are complied with. I use Aeroshell 15W - 50 semi-synthetic oil, changed every 50 hours and will be
surprised if things are gunked up or corroded but I might get shocked. I put over 100 hours on the Cherokee this
year including the 2000 nm cross country trip to Canada and back. I've averaged somewhere between 80 to 120 hours
per year on her for the 7 years I've owned her and have installed rebuilt mags once. We are going to pull the mag in
question and take a closer look. Thanks for confirming what my conscience was already subtly telling me to do.
