(*) Effective October 17, 2008 the models designation CFM56-7B18, CFM56-7B22/B2, CFM56-7B18/3, CFM56-7B22/3B2 were 
withdrawn at the request of the manufacturer. None of these models were released to revenue service. 
The Direction Generale de L'Aviation Civile (DGAC) originally type certificated these engine models under DGAC Certificate de Type 
Moteur M21. The FAA validated these products under Type Certificate Number E00056EN. Effective September 28, 2003, the European 
Aviation Safety Agency (EASA) began oversight of these products on behalf of France. EASA Type Certificate Number EASA.E.004 
was issued June 14, 2006.

E00056EN 20 of 27 
 
 
 The original production basis was French “Agreement de Production” No. F.G.007 or P03 issued 
by Direction Generale de L’Aviation Civile (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 European Aviation Safety Agency (EASA) Production 
Certificate FR.21G.0007. (See NOTE 10). 
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 E00056EN and is in a condition for safe operation.’

NOTE 7. 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, CFMI-TP.01.14, Section 3, for additive usage. 
NOTE 8. Life limits established for critical rotating components are published in Chapter 5 of the 
CFM56-7B Engine Shop Manual, CFM-TP.SM.10. 
NOTE 9. Power setting, power checks and control of engine thrust output in all operations is to be based 
on CFM engine charts referring to fan speed. Fan speed sensors are included in the engine 
assembly for this purpose. 
NOTE 10. The type certificate holder, CFM 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 certificate applies only to engines produced in France under EASA Type Certificate 
E.004. Engines of the same model designation produced in the United States under Type 
Certificate No. E00055EN 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 Certificate No. 108 are eligible for use in engines produced under this 
type certificate 
These engines, when produced by General Electric under Production Certificate No.108, are 
identified by an even numbered serial number prefix ( Reference CFM56-7B Service Bulletin 
72-0747 for a list of approved prefixes). 
 
All engines identified by an odd numbered prefix () will be produced by SNECMA under 
Production Certificate No.F.G.007. (Reference CFM56-7B Service Bulletin 72-0747 for a list 
of approved prefixes) 
Effective September 28, 2004, engines produced by SNECMA were produced under EASA 
Production Certificate FR.21G.0007. Engine serial number 893-133 was the first engine 
produced by SNECMA under the EASA Production Certificate 
NOTE 11. The minimum permissible idle in flight corresponds to N2=64.7% (9,350 rpm) below 25oF. 
Between 25oF (-3.8oC) and 40oF (4.4oC), the idle speed varies from 64.7% (9,350 rpm) to 
58.8% (8,500 rpm). Above 40oF (4.4oC), the minimum permissible idle speed is 58.8% (8,500 
rpm). Other EEC schedule limitations, such as minimum fuel flow and minimum PS3 
(including Mach No. bias for 7B27A,7B27A/3 & -7B27AE), may result in minimum N2 speed 
limitations in flight that are higher than the N2 limits listed above. All limits are non- 
adjustable and are preset into the EEC schedules. 
NOTE 12. 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, CFMI-TP.01.14, 
Section 6. 
NOTE 13. The normal 5 minute takeoff rating may be extended to 10 minutes for engine out contingency. 
NOTE 14 (a). The indicated maximum permissible takeoff exhaust gas temperature (EGT) is 950oC. These 
indicated takeoff EGT redlines are accomplished via an EGT shunt and an EGT trim in the 
ECU software as noted below. 
The effect on EGT (units oC) with respect to the indicated takeoff EGT redline value of 950oC 
for each of the models is summarized below:

* EGT shunt adds 30oC to actual measured engine EGT on CFM56-7B, 7B/3 and 7BE series 
engines, 10oC to actual measured engine EGT on CFM56-7B/3F and –7BE/F series engines, 
and 20oC to the actual measured engine EGT on CFM56-7B/2 series engines to provide an 
indicated EGT level. This EGT shunt is triggered above 8,500 RPM core speed for all CFM56 
series engines. For E series only, there is a 20oC profile EGT shunt (cooler) in addition to the present 
+30oC or +10oC (E/F series) shunt. This profile shunt (-20oC) will be active above 10400 rpm 
Physical Core speed (N2) and –10oC Shunt at ground idle conditions. This profile shunt will be active 
for all flight conditions. 
 
** The EGT trim function adds the values noted above to the indicated EGT levels. This EGT 
trim is only triggered at mach numbers from 0 to 0.40 and when the core speed is greater than 
11,200 RPM. This function is only applicable for the engine models indicated. 
 
NOTE 14 (b). The indicated maximum permissible maximum continuous EGT is 925oC. The same trims and 
shunts described in Note 14(a) for takeoff EGT are applicable to maximum continuous EGT. 
 
NOTE 14 (c). All CFM56-7B engines are certified with an indicated maximum permissible takeoff EGT 
transient allowance of 960oC for 20 seconds. This equates to a 10oC increase above the 
maximum permissible indicated value of 950oC. 
 
NOTE 15. The CFM56-7B27A, CFM56-7B27A/3 and CFM56-7B27AE variants are designed for military 
application only. The engine serial number of these variants includes 654, 655, 362 or 363 
depending on final assembly location. FAA certified engines used in military service are not 
necessarily operated or maintained in accordance with FAA regulations. Commercial service 
uses of the CFM56-7B27A, CFM56-7B27A/3 or CFM56-7B27AE variants, and the installation 
of used CFM56-7B27A, CFM57-7B27A/3 and CFM56-7B27AE parts in another CFM56-7B 
variant, are subject to prior approval of the FAA (Engine Certification Office, ANE-140).

NOTE 17. Criteria pertaining to the dispatch and maintenance requirements for the engine control systems 
are specified in the airworthiness limitation section of the CFM56-7B Engine Shop Manual
