John,
These finger screens are located at the lowest
part of each tank. You must disassemble the fuel line to each tank to gain
access to the screen fitting. Defueling the aircraft completely makes
this job easier.
Inspecting these screens every year is a bit
much. However if it's noticed that there is a fuel flow problem or bits
of screen and "other material" is in your gascolator or during the
preflight fuel sampling procedure you notice bits of the screen, it's time to
pull the tank and check/change the finger screen.
I inspected
my finger screens last year and to my surprise they were completely
corroded through. Log book
entries showed the last time anything was done to the tanks was nine years
ago. This aircraft was kept outside. Rain water through out the
years and low or no flying hours took it's
toll.
Since I've owned this aircraft it is
sheltered. I plan to inspect these screens again in two years when I
remove the tanks for the recurring center wing AD
inspection.

Where are the wing tank finger strainers located and how do you access
them? Is it critical to inspect them each and every year?
