Today I received the parts to modify the oil
tank mount brackets from Vans. Vans issued
a service bulletin after some cracks were discovered at annual inspections on
some aircraft. A new support rib is to
be installed at the bottom of the oil tank mount brackets. I decided to do the modification now instead
of waiting. This evening I set the new additional
rib in place. I then marked and drilled
the oil tank mount brackets. I will now deburr the edges and prep the rib
for primer and paint. After I have
primed and painted the rib I will rivet it into place.
