Avion provides engineering, specialized logistics and technical programmatic management services to the RDECOM Aviation Engineering Directorate (AED), Sustainment Division for the life cycle management of the Army Aviation Critical Safety Item/New Source Testing (CSI/NST) Program. Avion has been the primary sub-contractor supporting this program since 1993 via contracts DAAJ09-93-D-0057, DAAJ09-96-D-0023, DAAH01-00-D-0016 and most recently EXPRESS W31P4Q05A0014. Avion has an in-depth understanding of the TEAM REDSTONE activities and interactions relating to the CSI program. We have developed and established strong working relationships and interfaces with PEO-AVN and RDECOM AMRDEC AED Systems Engineering personnel for the various aircraft and engines, Integrated Materiel Management Command (IMMC), Safety Office, Engineering Directorate - Industrial Operations Division, and Acquisition Center personnel involved in CSI alternate source vendor qualification and program execution. Avion has been integrally involved in CSI monitoring, logistics support, program management, qualification, engineering testing and source approval since program inception. Our corporate experience and direct involvement with the formation and development of the CSI program has provided the Army with a valuable resource for planning and implementing an effective and comprehensive CSI program. Avion has played a key role in the qualification and/or removal from the fleet for hundreds of unqualified CSI, resulting in the reduction of flight safety risk presented to the Army Aviation fleet.
