Diamond Aircraft will not exhibit at EAA Airventure, the National Business Aviation Association convention, and AOPA Summit as a cost-savings measure. The company will continue to exhibit at law-enforcement and government security shows to demonstrate its special mission aircraft. The decision was a cost-saving move to focus on the D-Jet program and continue support of the piston-engine fleet, said Diamond President Peter Maurer. A recent loan from an unnamed source was to support development of the D-Jet. Maurer said the decisions were necessary because of the “…continued weakness of the economy,” and “…slow industry wide retail sales.” The company’s September open house at the factory in London, Ontario, will continue as planned.
