Couple of things that need to be done prior to the annual and most
importantly prior to even starting the engines......

1. Fresh oil change and at least 20 minuets on an external oil pump
for pre-oiling or if using a pressure type pre-oiler, then 10 fill
and drain cycles.

2. Battery replacement or charge check. If it won't hold a charge then
replace it.

3. Gear swing and rig check and lube. Do it by the book and no
shortcuts....

4.Power up the aircraft with external power and do a good sniff check.

Once you've done this then fire up the engines and do some taxi
testing and get ready for the annual.

And see how old those fuel and oil hoses are. Ten years is the
outside limit, and five is more reasonable. They get brittle and crack
with age and can cause some serious second thought.
The oil filters should be checked after a couple of hours
running. Running the engines on the ground a few times puts a whole
lot of moisture into the case and causes acid formation and corrosion.
If the bearings/journals and pistons/rings have been roughed up by
corrosion there might be metal in the filters.
