of Italy and Adria Airways of Slovenia.
The aircraft will be offered with the CF34-8C5,
-8C5A1 and -8C5A2 engine models. For
the CRJ1000, the engines feature a new
first-stage, high-pressure turbine nozzle
and other enhancements
for durability,
targeted to deliver
up to 12%
lower engine
maintenance costs.
• ARJ21 Regional Prepares for Flight Testing:
Powered by two GE CF34-10A engines, the
ARJ21-700* regional jet is in final preparations
to make its inaugural test flight by year’s end.
Developed by the Shanghai-based
Commercial Aircraft Corporation of China, Ltd.
(COMAC), the 90-seat ARJ21-700 is the first
medium- to short-range regional airframe
designed entirely within China. The powerful
CF34-10A engines are ideally suited for
China’s diverse environment, including the hot
temperature and high-altitude conditions on
many routes in western China.
The 70- to 90-passenger aircraft is expected
to obtain its airworthiness certificate next
year. There are now announced orders for
206 of these aircraft, with the first production
ARJ21-700 slated to be delivered to Shandong
Airlines in fall 2009.

GE Caledonian Shop to be GEnx Service-Ready . . . continued from page 1
CF34 Engine Program Reaches Major Milestones
• By end of year 2008: Following the full
disassembly, now complete, all engine
parts are currently undergoing thorough
cleaning and inspection (including fluorescent
penetrant inspection), a process that is
scheduled for completion by year-end.
• Scheduled to begin January 2009: The
next step in the process is reassembly of the
engine, wrapping up the shop certification
process by spring 2009.
As the Caledonian shop progresses
through each step, representatives from
several organizations are on site to support
the manuals and tooling validation effort,
including Product Support Engineers, Field
Service Engineers, Support Equipment Tooling
Engineers and Technical Publication experts.
Already an active maintenance, repair and
overhaul facility, the GE-owned Caledonian
shop currently services the CF6* engine family.
Once the shop receives its FAR 145 repair
station certification, it will be approved for
maintenance and alterations of the
GEnx powerplant.
Says Gallick, “Validating the processes,
manuals and tooling at this stage of the
program will lead to improved throughput in the
overhaul process and a streamlined workflow.”

GE Aviation is celebrating 150 million
flight-hours on the CF6-80C2 engine fleet—
that’s nearly 18,000 flight-hours per day for the
23 years these engines have been in service.
CF6-80C2 Engine Milestone
150 Million Flight-Hours and Counting
Recent CFM International and CF34*
repair releases reduce customer costs and
increase engines’ time on wing:
CFM56-3 Combustion Case Aft End
Replacement: A repair that replaces a
distressed section with new material,
salvaging parts previously unserviceable
and reducing the scrap rate by up to 60%.
CFM56-5A, -5B, -5C, -7 Combustion
Chamber Aft Datum Flange Replacement:
This repair uses the new Tech Insertion
flange as an upgrade to the current design,
improving durability. This is accomplished
through reduced cracking and separation
from the combustor case.
CF34-8 Low-Pressure Turbine (LPT) Stage
4 Blade Light Repair: This repair addresses
missing or depleted coating, minor dents and
scratches and repairs the airfoil twist. The
repaired coating provides for an additional
repair cycle and achieves a yield of 96%.

CF6-80C2 Engine File
Logging more than 40,000 flight-hours and nearly 10 years of continuous on-wing
operation on a Boeing 767* aircraft, American Airlines recently set a time-on-wing record for a
GE CF6-80C2 engine. This record is equivalent to making 2,000 round trips from Dallas, Texas,
to London, England, without ever removing the CF6-80C2 engine from the wing of the aircraft.
In addition to this record-setting engine, American has several other CF6-80C2 engines in
its fleet that have surpassed 35,000 continuous hours on wing.
“This record is an outstanding achievement for American Airlines and our CF6-80C2
