AMAC Aerospace Switzerland AG has successfully returned to service an A319 VIP aircraft after a STC level modification and a heavy base maintenance project.  This major refurbishment and modification project included a customized VIP carpet replacement, a re-upholstery of all seats and divans and an installation of a new in flight entertainment system offering HD monitors as well as audio video on demand with wireless streaming to personal electronic devices.  A second stand alone high speed SATCOM system was installed to offer passengers further connectivity.  Due to the cabinet modifications, the customer is pleased to have received additional storage capacities and more space in the cabin during its operations.  The modification and refurbishment work was carried out in parallel with a heavy base maintenance project including landing gear overhauls.  The cabin refurbishment was performed and certified on time during a very challenging ground time to meet the operational requirements as well as the customers’ expectations.
