The LCAS fully certified (Supplemental Type Certificate) roller floor system installs into the available sea tracks and does not affect cargo tie-down provisions.
This modification involves the installation of a cargo floor roller system. The roller system consists of two Ancra ball mat trays (P/N 83774-01/-10 and 83744-02/011) located in the area of the aft cargo door, and a series of Ancra roller tray assemblies (P/N 83628-18) along the rest of the floor forward of the cargo door. The transition between the roller tray assemblies and the ball-mat is a row of modified Ancra roller rail assemblies (P/N 81384-10M). The roller rails are modified to have a slope of 1 degree to provide a smooth transition from the ball mat to the roller trays.
