Diane De Souza, vice president of Bombardier’s parts services team, will retire after 28 years with Bombardier Aerospace, effective this summer. She is succeeded by Bill Molloy, previously director of CSeries customer services and support, who assumed his new role April 1. Under De Souza’s leadership, Bombardier’s parts services team was transformed to meet the challenges of a growing international customer base and a quickly expanding array of products.
