In an effort it says is aimed at better serving customers, Honeywell's aerospace division is planning a major restructuring that will consolidate  operations into three business segments and result in an unknown number of job cuts. The shakeup at Honeywell comes on the heels of Rob Gillette's appointment as president and CEO of the company's $9.75 billion aerospace division based in Phoenix. Scheduled to take effect July 5, the realignment should be completed by the end of the year. As a result of the restructuring, Honeywell's engines, avionics and wheels-and-brakes divisions essentially are being replaced by three units–airline; business and general aviation; and space and defense. "We needed to change how we do things," Gillette told AIN. "I spent a great deal of time in the past few months talking with our customers, and they told me that Honeywell wasn't always the easiest company to work with. Clearly that has to improve." Product-support activities will continue to be combined, but Gillette said he wants to improve the company's ability to respond to customer needs. For example, Honeywell will soon have a single telephone number customers can call, serving as the "single place the customer knows he can turn to for answers," Gillette said.
