Finally got the news recommending RV8 main spar replacement due to countersinking main spar flange too deep for skin dimples.
My countersink depth measured with an inserted rivet is .015", diameter is .234" with no hole elongation or knife edge.
I now know the ideal depth is .006" past flush but having a hard time believing .009" over is a deal breaker.
I am assuming a new spar would require new Z brackets, tank baffle, and possibly joint plate to get things in proper alignment.
Any advise on how to proceed maybe have a tech inspector put some eyes on it?
