Abstract: A mounting system is provided including a center platform having a plurality of mounting lugs for mounting the center platform transversely extending at least partially through an aircraft cabin with a first end and second end of the center platform adjacent a respective first and second side opening of the aircraft cabin. A first support pylon may be removably coupleable to the first end of the center platform to extend outwardly from a first side of the aircraft. A second support pylon may be removably coupleable to the second end of the center platform to extend outwardly form a second side of the aircraft. A modular floor component may be removably coupleable relative to a longitudinal side of the center platform to provide a substantially planar load surface including a top portion of the modular floor component and a top surface of the center platform.
