NOTE 7. FUEL
Approved fuels must conform to GE Specification D50TF2. Certain fuels such as those produced to PRC
Specification RP3 meet the requirements of D50TF2 by means of the Specification. The engine will operate with a
mixture of fuels or additives conforming to GE Specification D50TF2.
NOTE 8. Life limits established for critical rotating components for:
GE90-76B/-77B/-85B/-90B/-94B are published in Chapter 5 of the GE90 Engine Manual, GEK 100700
GE90-110B1/-113B/-115B are published in Chapter 5 of the GE90-100 Engine Manual, GEK 109993
NOTE 9. Power setting, power checks, and control of engine thrust output in all operations are based on Fan Speed (N1). Speed
sensors are included in the engine assembly for this purpose.
NOTE 10. GE90-76B engines with configuration type box number 320-839-501-0 must incorporate the HP/LP turbine hardware
and associated changes per General Electric GE90 Service Bulletin 72-169. The FADEC incorporates a 30ºC shunt.
The corresponding indicated EGT limits are 975ºC (take-off), 980ºC (take-off with 60 second max. transient), and
965ºC (max. continuous).
NOTE 11. For ground operation in icing conditions the following procedures must be observed:
GE90-76B/-77B/-85B/-90B/-94B
During ground operations (including taxi-in and taxi-out) in icing conditions, the pilot must perform one of the
following shed procedures:
(a) Run up the engines momentarily to a minimum of 50% N1 at intervals not to exceed 15 minutes, or
(b) For operation at ambient conditions of -6 ºC (23 ºF) and above, and at airport altitudes up to 3,048 meters (10,000
ft), perform the following at intervals not to exceed 60 minutes:
1) Increase throttle to a minimum of 55% N1
2) Dwell at the specified N1 for 20 seconds minimum
3) Decelerate to idle or proceed with normal takeoff procedure.
See GE90 Operating Instructions Manual GEK 100703.
GE90-110B1/-113B/-115B
During ground operations (including taxi-in and taxi-out) in icing conditions, the engine must be run up momentarily
to a minimum of 50% N1 at intervals not to exceed 60 minutes. See GE90-100 Operating Instructions Manual

NOTE 16. The normal 5 minute takeoff time limit may be extended to 10 minutes for engine out contingency.
NOTE 17. TIME LIMITED DISPATCH CRITERIA
Criteria pertaining to the dispatch and maintenance requirements for the engine control systems are specified in:
For the GE90-76B/-77B/-85B/-90B/-94B see General Electric Document GEK 103084 and the Airworthiness
Limitations Section of the GE90 Engine Manual GEK 100700, which defines the various configurations and
maximum operating intervals.
For the GE90-110B1/-113B/-115B the requirements are defined in the Airworthiness Limitations section of the GE90-
100 Engine Manual GEK 109993
NOTE 18. For approval of repairs of fan blade composite material in the root section of the fan blade up to the inner annulus flow
path line see the Airworthiness Limitations Section of GE90 Engine Manual GEK 100700 for the GE90-76B/-77B/-
85B/-90B/-94B and GE90-100 Engine Manual GEK 109993 for the GE90-110B1/-113B/-115B.
NOTE 19. Note deleted.
NOTE 20. Reserved.
NOTE 21. The FADEC unit P/N originally defined both hardware and software. The hardware and software are now defined by
separate P/Ns. The engine should be equipped with a FADEC defined either by the combined P/N or by the hardware
and the software P/Ns.
NOTE 22.
NOTE 23.
An exemption to §21.19(a) was granted and issued in Washington, DC, on August 26, 2002, for the GE90-110B1/-
113B/-115B engine models. This exemption allowed GEAE to amend Type Certificate No. E00049EN to add these
models rather than apply for a new type certificate for those engines, subject to the following conditions and
limitations:
1. GEAE must comply with §21.17 as if it was a new type certificate.
2. GEAE must conduct a large flocking bird test as part of compliance with §33.76, Bird Ingestion.
3. GEAE must include an engine test to demonstrate compliance to §33.90, Initial Maintenance Inspection.
4. An applicant installing the GE90-110B1/-113B/-115B engine models into an aircraft must comply with
all of the applicable airworthiness standards for a new type certificated engine, including applicable aircraft
special conditions.
Demonstration of compliance to §33.73(b) Power or Thrust Response is installation specific to the B777-
200LR/300ER and B777 Freighter airplanes for the GE90-110B1/-113B/-115B model engines. Installation of these
model engines on different airplane models or types will require a separate evaluation and finding of compliance to
§33.73(b).
NOTE 24. The engine oil tank filler cap of GE90-76B/-77B/-85B/-90B/-94B and GE90-110B1/-113B/-115B engine model meet
the requirement of §33.71(c)(4).
