RV14: Page 18-03, NOTE preceding Step 7.
"To ensure proper part alignment upon reassembly, leave every tenth hole on the T-00001 Fuel Tank Skins un-countersunk." . . . . then to go back and countersink these and rivet after initial batch of sealant has cured.
How does not countersinking every tenth skin hole now help to ensure proper alignment of parts later if only 1 in 10 holes is not countersunk/riveted? Of 74'ish rivet holes, how can leaving out 7 rivets ( and the countersinking?) ensure proper alignment of those parts? I am assuming the parts referred to are the tank skins and the tank baffle. And, not countersinking can't have anything to do with alignment of the two parts, or can it?
I am definitely missing something here and I don't want to miss some bigger picture behind the instruction. Curious mind needs to know.
