ABSTRACT The assembly of aircraft structure using fasteners can be very difficult and expensive. Some of the most difficult assembly areas occur in compact structures, such asstruts (pylons), or major body and wing joints. These dif-ficult access areas drive up assembly costs and reducevelocity through the production line. Design engineershave traditionally compensated by designing accessholes with associated doublers to provide access forassembly. Another option is to over-design the joint byutilizing abnormally large quantities of current marketblind bolts to compensate for lack of performance. To address the problem, a new concept in fasteners, called the One Sided Installation (OSI ) bolt, has been developed in a joint endeavor between Boeing Commer-cial Airplane Group–Wichita Division and MonogramAerospace Fasteners of Los Angeles, California. Thisbolt utilizes new design features to obtain excellent struc-tural joint fatigue performance. The OSI is a revolution-ary design culminating four years of effort. This bolt isthe first blind bolt capable of equivalent usage with shearrated solid shank bolts in fracture critical structu
