Abstract : The structural box of the L-1O11 vertical fin, was redesigned using advanced composite materials. The box was fabricated and ground tested to verify the structural integrity. This report summarizes the complete program starting with the design and analysis and proceeds through the process development ancillary test program production readiness verification testing, fabrication of the full-scale fin boxes and the full-scale ground testing. The program showed that advanced composites can economically and effectively be used in the design and fabrication of medium primary structures for commercial aircraft. Static strength variability was demonstrated to be comparable to metal structures and the long term durability of advanced composite components was demonstrated.
