Brief Description: Cut inboard tank rib for access
Used a fly cutter to cut out the access hole opening in the inboard rib. They never say how much of it to cut out. I put the trim ring on the rib, and surmised we cut out as much of th rib as we can, while leaving the raised ring punched in the rib.
Deburred and sanded the hole.
The ring shows we want to keep the raised ring on the rib
