The major FWF categories I focus on=20 are:
 
Fuel System
Ignition System
Lubrication System
Coolant System
Engine
   a.  Induction
   b.  Exhaust
Gearbox
Electrical System
EC2
Prop/Spinner

For example on the Fuel system here is = what I check=20 for.
 
Fuel = System:
1.  Check all FWF Fuel = connections/lines for=20 evidence of leaks/chaffing/damage (examine connections=20 closely) 
2.  Drain Sump tank, remove quick = drain,=20 inspect "O" ring - replace drain
