Composite flight service programs are in progress on two Lockheed aircraft, the L-1011 and C-130. A set of Kevlar-4/epoxy fairings are being flight tested on three L-1011's, and have had no major service problems after 10000 hours service. The center wing box aluminium skins and hat stiffeners were reinforced with pre-cured, bonded boron/epoxy strips on three C-130's. After almost three years and over 4000 flight hours, these components are continuing to perform satisfactorily in service. Another flight service component on the L-1011 is a graphite/epoxy floor post, which is free of service problems or defects after 10000 flight hours. These components provide significant verification of the serviceability of all three major composite reinforcement types. (Hannebauer)
