Hamilton Sundstrand Systems Help Enable A400M Appearance at Farnborough Air Show

FARNBOROUGH, England, July 19, 2010 - FARNBOROUGH AIR SHOW — Hamilton Sundstrand's A400M systems have
performed well throughout the aircraft's flight test program and helped
enable the aircraft's visit to the 2010 Farnborough Air Show. Hamilton
Sundstrand is a subsidiary of United Technologies Corp. (NYSE: UTX).

"Hamilton Sundstrand is proud of its long and successful partnership with
Airbus and EADS," said Hamilton Sundstrand President Alain Bellemare. "We are
pleased to continue that relationship by playing a significant role in the
A400M's development."

Hamilton Sundstrand supplies the A400M's Secondary Electrical Power
Distribution Center (SEPDC), Auxiliary Power Unit (APU) and Ram Air Turbine
(RAT) emergency power system. Ratier-Figeac of France, a Hamilton Sundstrand
business, supplies the A400M's Trimmable Horizontal Stabilizer Actuator
(THSA), the Throttle Control Assembly (TCA) and its Propeller System.

The A400M's Propeller System, which is 17.5 feet in diameter and produces
11,000 shaft horsepower, enables the aircraft to cruise comfortably at Mach
0.72. The Propeller System is manufactured at Hamilton Sundstrand's
Ratier-Figeac business, in Figeac, France, and has eight full composite
blades made with carbon spar and composite shell.

The SEPDC provides switching and protection for the aircraft's
approximately 1,000 electrical loads using solid state power controller
technology. It also controls up to 15 utility functions.

The A400M APU — mounted in an upper wing fairing — provides pneumatic
power for starting the main engines, and electric and pneumatic power to
operate aircraft systems when the engines are not running.

The RAT provides 43 kVA of electrical power to critical loads in the
event of a total power loss.

The entirely fly-by-wire THSA controls the plane's tail position through
the flight control computer. At 1.5 meters long, it is one of the largest and
most powerful THSAs ever built for a military aircraft.

The Throttle Control Assembly (TCA) is part of the Cockpit Systems and
allows the pilot to control the powerplant (Engines and Propeller Systems).
The TCA movable soft detent device provides the powerplant rate information
to the pilots and helps for Auto-pilot disconnection.

With 2009 revenues of US$5.6 billion, Hamilton Sundstrand is
headquartered in Windsor Locks, Conn. Among the world's largest suppliers of
technologically advanced aerospace and industrial products, the company
designs, manufactures and services aerospace systems and provides integrated
system solutions for commercial, regional, corporate and military aircraft.
It also is a major supplier for international space programs.

United Technologies Corp., based in Hartford, Conn., is a diversified
company providing high technology products and services to the building and
aerospace industries worldwide.
