MONTREAL--(BUSINESS WIRE)--April 26, 2004--Teradyne, Inc. (NYSE:TER) announced that Delta TechOps, a division of Delta Air Lines, has selected Teradyne's Next Generation Automated Test System (NxGen ATS) to support Delta's fleet of Boeing aircraft. In addition, Delta TechOps will use the NxGen(TM) ATS to service and maintain the Boeing aircraft owned by their MRO (Maintenance, Repair & Overhaul) customers. Teradyne made the announcement at the Avionics Maintenance Conference held here April 26-29.

Delta TechOps is the launch customer for the NxGen ATS, which Boeing developed based on Teradyne's Spectrum(TM) 9000-Series functional test system. Boeing has licensed Teradyne to manufacture and market the NxGen ATS to commercial airlines and MROs for maintenance and repair of Boeing commercial avionics.

Together, Delta, Boeing, and Teradyne have teamed up to roll-out the NxGen ATS to the industry, demonstrating the vital role that NxGen will play in commercial avionics from the factory to the field," said Carl Rosenblatt, Teradyne business unit manager. "Not only is Teradyne a technology leader in the dynamic ATE industry, but it also provides a world-wide support infrastructure that ensures that the needs of Boeing customers will be met around the world."

As part of the agreement with Delta, Teradyne will supply NxGen ATS hardware, training, and support, and Boeing will deliver component maintenance manual (CMM)-sanctioned, FAA-certified test programs. Teradyne will support Delta in the integration of the NxGen ATS into its operations, leading to the retirement of the ATS-182 test system and providing Delta with an industry-leading test capability for its MRO operations.

"As Delta implements NxGen within our operations, we are looking forward to the cost savings of having a single test platform," said Larry Hieber, manager - TechOps Avionics. "NxGen ATS will provide a much-needed replacement for older test systems such as the ATS-182. This will help reduce overall airplane maintenance costs by cutting down the number of automatic test systems we buy and support."

Leslie Lauer, director of Retrofit Engineering in Boeing, Commercial Aviation Services, added, "Our work with Teradyne gives airlines and MROs a test solution that will support their needs today and long into the future. The NxGen test system provides an innovative and flexible test solution to minimize risk and reduce testing costs."
