LE HAVRE, France -- February 6, 2014

Nexcelle – the joint venture of Aircelle (Safran) and GE Aviation’s Middle
River Aircraft Systems for a new generation of engine nacelles on integrated
propulsion systems – has delivered its first O-Duct nacelle to equip CFM
International’s* LEAP-1C engines for the COMAC C919 jetliner.

“Innovation is an important element in Nexcelle’s development of new engine
nacelles, and the O-Duct is an example of how our approach to more integrated
propulsion systems will benefit aircraft manufacturers and airline operators,”
said Nexcelle President Michel Abella.

Developed and manufactured by Aircelle, this innovative O-Duct marks a
milestone in Nexcelle’s production hardware deliveries, and is to be used –
together with other nacelle components – for engine flight test.

Nexcelle has also delivered the first LEAP-1C air inlet from Middle River. The
hardware has been installed on a LEAP development engine currently undergoing
tests.

The one-piece composite O-Duct delivered by Nexcelle is a technology
breakthrough in nacelle design for integrated propulsion systems, replacing a
traditional thrust reverser’s two-piece “D” doors. When deployed, the O-Duct
moves aftward to the reverse thrust position,eliminating drag links in the
engine’s secondary flow-path, enhancing the airflow path and improving fuel
consumption, while also increasing thrust reverser efficiency.

A key feature of the O-Duct is its single-piece, 330-deg. carbon composite
inner skin, which is produced at Aircelle’s Le Havre, France manufacturing
facility using an innovative molding process employed for the first time on
this program. The milestone no. 1 O-Duct is now at GE Aviation’s Peebles, Ohio
facility, for built-up with the other nacelle components prior to installation
on the CFM flight test aircraft.

Aircelle and Middle River Aircraft Systems will be building the equivalent of
18 initial nacelle shipsets, to be used as complete nacelles for flight
testing, and as separate components in such applications as ground-based icing
and crosswind testing.

Created in 2008, Nexcelle has been selected to supply the nacelle systems for
two major engine programs: the CFM International LEAP-1C for COMAC’s C919
jetliner, and the GE Aviation Passport™ for Bombardier’s Global 7000** and
Global 8000** business aircraft.
