Brief Description: Cleaned up Fuselage/Pilot Holes in Stringers
Took aft top skin off. Vacuumed out fuselage. Deburred some holes. Drilled out the two temporary pop-rivets that joined the aft ends of the stringers to the F-608 bulkhead. Clecoed skin back in place. Used nutplate jig to drill #40 holes in the five holes that were missed when back-drilling. Back-drilled the skin through the junction of the stringers to the F-608 bulkhead. Measured out pilot holes in the stringers between bulkheads F-606 and F-607 to be 1 1/4'' beginning from centerline of flange of F-607.
