BELLEVUE, Wash., April 9, 2009 — Esterline Corporation (NYSE: ESL www.esterline.com), a leading specialty manufacturer serving principally aerospace and defense markets, announced today that its Advanced Sensors operation has been chosen by Rolls-Royce to partner on its Trent XWB engine program.

The Rolls-Royce Trent XWB is the sole engine currently available to power all variants of the new Airbus A350 XWB family of aircraft. To date, Rolls-Royce has received over 1,000 orders for Trent XWB engines.

Robert W. Cremin, Esterline’s Chief Executive Officer, said Esterline will be responsible for the supply of approximately 30 separate components in the sensors package. At least 75% of these components “...will be produced in-house at our Advanced Sensors facilities, including our U.K.-based Weston Aerospace operation, our France-based Auxitrol operation, our U.S.-based Norwich Aero operation, and our new facility in Mexico,” he said. The balance of the package will be procured from strategic suppliers to Esterline.

The first Esterline-supplied Trent XWB components are scheduled for delivery to Rolls-Royce in early 2010. Initial ground testing of the Trent XWB is due to commence in late 2010, with entry into service of the new Airbus airliner scheduled for 2013.

Cremin estimated the agreement would generate approximately $500 million in revenue over the life of the program. He said Esterline will act as a Tier 1 supplier in an arrangement that “...enables us to earn revenue from every flying hour over the entire life of the program.”

Esterline Advanced Sensors serves the gas turbine and aircraft markets with a range of pressure, speed and temperature sensors. It employs over 900 people in manufacturing facilities located in Europe, the United States and Mexico.

Esterline Advanced Sensors supports many current Rolls-Royce civil engine programs, including the RB211-535, RB211-524, BR710, BR715, Trent 500, Trent 700, Trent 800, and Rolls-Royce’s industrial and military applications. It provides all-inclusive customer service and support on its components via its dedicated aftermarket division ‘Esterline Sensor Services.’
