Brief Description: Catching up on lost rivets, part 2
A number of rivets remain which have been clecoed using #40 pilot holes, but which must be opened to the final size. Many of these must be drilled from beneath the aircraft.
1. Opened rivet holes connecting wing spar carry through to cabin floor, 6B10-1, using #20 bit for A5 rivets. 2. Opened rivet holes connecting ge3ar channel 6B5-5 to rear fuselage floor, and to cabin floor, using A5 rivets. 3. Clecoed selected holes to maintian junction of assembly.
Note 1: rivets immediately over the steel beams used to support the fuselage must be drilled later. Note 2: Because these rivets needed to be drilled from underneath the aircraft, they required slightly longer than might have otherwise been the case.
