What was found
WHILE PERFORMING UNRELATED MAINT MOVEMENT WAS NOTED IN THE WING ATTACHMENT AREAS. INVESTIGATION OF MOVEMENT REVEALED THAT THE NUT ASSEMBLY ON BOTH THE LEFT AND THE RIGHT WING ATTACHMENTS WERE INSTALLED BACKWARDS. TECH SUPPORT WAS CONTACTED, BOLTS REPLACED AND INSTALLED CORRECTLY, SO AIRCRAFT COULD BE FERRY FLIGHTED TO MANUFACTURER FOR INVESTIGATION. INVESTIGATION SHOWED THAT THERE WERE ABRATION MARKS ON THE STRUCTURE OF THE WING ATTACHMENT NUT SEAT THAT WOULD REQUIRE REPAIR. MANUFACTURE DETERMINED THAT THIS IS REPAIRABLE AND WILL PROVIDE 8100-9 AUTHORIZATION TO DO SO.
