Doing a little work on old Cessnas for fun these days and have to tell you I
don't like Phillips head screws. The slightest corrosion and they stick
and freeze. Then your Snap-On screwdriver (make sure it fits) wallows the
head out, as you grunt and cuss. Then you have to pull out the old die
grinder and disc a groove in the dam* thing and go pull out your common
screwdriver. Last night taking off a set of wheelpants where corrosion
thrives, I had screw after screw frozen up and had to pull the compressor
out on the ramp several times --- cause it had to go back to the shop for a
recharge.

Time to go to Allen screws. Yes. The entire Phillips head screw
population is held in contempt. They ought to be banned.
