PRESS RELEASE

Pratt & Whitney GTF Engine MRO Network Formalized

PARIS AIR SHOW, Paris, Tuesday, June 16, 2015

Pratt & Whitney and its OEM collaborators, Japanese Aero Engines Corporation (JAEC) and MTU Aero Engines AG (MTU), signed a definitive agreement formalizing a maintenance, repair and overhaul (MRO) network through International Aero Engines LLC and naming initial locations where PW1100G-JM engine maintenance visits will be performed. PW1100G-JM engine maintenance locations include Pratt & Whitney's facility in Christchurch, New Zealand; MTU's maintenance center in Hanover, Germany; and JAEC's IHI Corporation overhaul center in Mizuho, Japan. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.

"This is a very exciting time for the PW1100G-JM engine program and we are very pleased to have formally established our initial network of MRO providers," said Matthew Bromberg, president, Pratt & Whitney Aftermarket. "This global MRO network will provide customers with access to our experienced, high-volume shops that will incorporate best practices and offer the highest quality services at competitive costs."

Pratt & Whitney is working to expand its service network beyond its program partners. As the volume of shop visits grows, the overhaul capability will expand outside of the Pratt & Whitney partner network to include airline shops and independent maintenance, repair and overhaul shops as appropriate.

"Our customers demand flexibility and choice when making the important decision of selecting a partner to maintain their engines, and that is what we aim to provide with our GTF engine aftermarket network," Bromberg said. "By 2020, when the first wave of GTF engines is expected to come in for their first overhauls, more than 10 engine overhaul shops will be available to provide quality service to customers."

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines and auxiliary power units. United Technologies Corp., based in Hartford, Connecticut, provides high-technology systems and services to the building and aerospace industries.
