VERO BEACH — Piper Aircraft has reached an agreement with Aviall, Inc., a wholly-owned subsidiary of The Boeing Company, to distribute parts to its estimated 90,000 planes still flying and in need of servicing.Availl was granted worldwide distribution rights for marketing and sales of original spare parts for the 72-year-old airline manufacturer. Piper was bought last year by Imprimis, a Singapore-based investment company which has based its business plan on bringing the PiperJet to market and expanding its base of operations into Asia. Piper planes are flying on every continent and are supported by 65 service centers and 27 dealers.”Aviall’s strategically placed distribution centers worldwide, coupled with its ability to stock sufficient inventory to meet customer needs in a timely fashion, make it the logical choice for Piper,” said Derek Zimmerman, Piper’s Vice President of Supply Chain and Aftermarket Development. “We expect our customers to see a quantum leap in their ability to get the parts they need, when they need them and at a price and level of quality that reflects Piper’s standards of excellence.”
