changed to "CFM56-5-A1/F", at the r equest of the manufacturer. No
CFM56-5A2 models were released to revenue service.
PRODUCTION BASIS The original production basis was "Agreement de Production" Numbers F.G.007 or P03
issued by the DGAC for engines produced in France by Snecma under license from
CFM International, S.A. Effective September 28, 2004, these engine models were
produced under EASA Production Certificate FR.21G.0007. (See NOTE 11)
IMPORT
REQUIREMENTS
To be considered for installation on aircraft registered in the United States, each
individually imported engine must be accompanied by an EASA airworthiness approval
certificate (EASA Form 1 – Authorized Release Certificate) or JAA Form 1 issued by
Snecma on behalf of EASA under EASA Production Certificate FR.21G.0007.
The EASA Form 1 – Authorized Release Certificate, or JAA Form 1, should contain the
following statement: ‘The engine covered by this certificate has been examined, tested,
and found to conform to U.S. Type Certificate No. E29NE and is in a condition for safe
operation. See Note 11.
’

Fuel limits
Oil limits
Operation and air/ground starting pressure limits extend from a minimum
fuel pressure of not less than 5.5 psia (37.9 kPa absolute) above the true
fuel vapor pressure to a maximum of 60 psig (413.7 kPa gauge), relative to
atmosphere, with vapor/liquid ratio of zero at all conditions. For limits, see
Installation Manual, Part A, Section 5, Figures A2 through A5.
The minimum pressure limit at idle is 13 psid (89.6 kPa differential) and
varies up to 45 psid (310.2 kPa differential) at cruise thrust. The maximum
pressure limit during cold starts is 300 psid (2069 kPa differential), limited
by a pressure-relief valve. See NOTE 14.

- Std + 22 oC (37oC, 98.6oF) for -5A5 & -5A5/F
Maximum continuous is nominally independent of ambient temperature (flat
rated) to Std +10øC (25øC, 77øF);
Zero customer bleed and horsepower extraction;
No scrubbing drags;
100% inlet recovery; and
Based on CFM International referee separate flow exhaust system with
primary exhaust nozzle (core) P/N 15-25200-2014 and fan nozzle P/N
4013356-302.
NOTE 5. CFM56-5, -5A4, -5A5 Indi cated 890øC EGT redline corresponds to
actual of 890øC.
CFM56-5A3, -5-A1/F, Indicated 890øC EGT redline corresponds to
-5A4/F, -5A5/F actual of 915øC, and indicated 855øC EGT

NOTE 8. Approved fuel conforming to GE Specification D50TF2. MIL-T-5624,
Grades JP-4 or JP-5, ASTM D 1655, Jet A, A1 and B are consistent with
this GE Specification. Primary fuel is Jet A, with other fuels listed being
acceptable alternates. No fuel control adjustment is required when
changing from primary to alternate fuels. Use of aviation gasoline is not
authorized. Consult Specific Operating Instructions for additive usage.
NOTE 9. Life limits established for crit ical rotating components are published in the
CFM56-5 Shop Manual, Chapter 5.
NOTE 10. Power setting, power checks and control of engine thrust output in all
operations is to be based on CFMI engine charts referring to fan speed.
Fan speed sensors are included in the engine assembly for this purpose.
NOTE 11. The type certificate holder, CF M International, S.A., is a company
established and jointly owned by Societe Nationale l'Etude et de
Construction de Moteurs d'Aviation (SNECMA) of France and the General
Electric Company for the certification, sale, and support of CFM56 series
engines. With respect to the benefits of type certification for production,
General Electric and SNECMA function as licensees of CFM International,
S.A.
This type certification applies only to engines produced in France under
EASA Certificate E.067.. Engines of the same model designation produced
in the United States under Type Certificate No. E28NE are identical to and
fully interchangeable with engines produced under this type certificate.
Similarly, modules, assemblies, or parts produced in the United States
under Production Certification No. 108 are eligible for use in engines
produced under this type certificate.
These engines, when produced by General Electric, are identified by the
serial number prefix "730 and 732"; when produced by SNECMA, they are
identified by the prefix "731 and 733".
NOTE 12. A suffix may be added to the basic engine model number on the engine
nameplate to identify minor variations in engine configuration, installation
components or reduced ratings peculiar to aircraft installation requirements.
For example: CFM56-5xx.
Engines that have a suffix to the basic model number are identified in CFM
International Service Bulletin No. CFM56-5 72-001, and are summarized
below:
(1) CFM56-5-A1, basic model for Airbus A320
NOTE 13. The minimum permissible idle in flight corresponds to N2=58.8% (8,500
rpm), which is a non-adjustable limit, preset into the ECU control schedule.
TCDS E29NE PAGE 7
NOTE 14. During negative-g operation only, it is permissible to operate below
minimum oil pressure (13 psid) for a maximum of 10 seconds. See Specific
Operating Instructions , Section 6.
NOTE 15. The models shown on this TCDS have the following general characteristics:
MODEL CHARACTERISTICS
CFM56-5 Basic model.
CFM56-5-A1/F Same as CFM56- 5 except EGT limits increased
through introduction of hot section modifications.
This model was originally certified as CFM56-5A2,
but that designation was changed at the request of
the manufacturer.
CFM56-5A3 Same as CFM56-5-A1/F except for increased takeoff
thrust rating.
CFM56-5A4 Same as CFM56-5A3 except for reduced thrust
takeoff rating and lower EGT limits.
CFM56-5A4/F Same as CFM56-5A3 except for reduced thrust
takeoff rating
CFM56-5A5 Same as CFM56-5A3 except for reduced thrust
takeoff rating and lower EGT limits.
CFM56-5A5/F Same as CFM56-5A3 except for reduced thrust
takeoff rating.
NOTE 16. The CFM56-5, -5-A1/F, -5A3, -5 A4, -5A4/F, -5A5, -5A5/F FADEC series
engines have been approved to operate with certain faults present in the
control system, based on satisfaction of 14 CFR Part 33 requirements and
appropriate engine control system reliability requirements. FAA approved
criteria pertaining to dispatch and maintenance requirements for the engine
control system are specified in GE Document No. GEK 98455, which
defines the dispatchable configurations and maximum operating intervals.
A control system reliability monitoring program has been established with
CFMI, as a contingency of the dispatch criteria approval, to ensure that
overall engine control system and specific component failure rates do not
exceed the maximum values permitted by the reliability analysis.
NOTE 17. The normal 5 minute takeoff rating may be extended to 10 minutes for
engine out contingency.
