I need some information regarding a structural issue.
I recently imported RV-7A 71975 to South Africa from USA. The rear empennage cover was secured with rivets instead of screws so when the aircraft was re-assembled here in SA, the re-assembler put rivnuts in the rivet holes so that the cover could be screwed in place. The original builder put quite a lot of rivets in an the guy this side put rivnuts in every hole. When fitting one of the rivnuts they drilled through the skin and also through a small piece of the spar.
approximate position of the hole
approximately how much has been drilled out of the edge of the spar i.e a half moon piece the size of half an 8/32 rivnut.
Has the hole compromised the integrity of the spar and if so what would need to be done to rectify the problem?
