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. ’ NOTES NOTE 1. MAXIMUM PERMISSIBL E TEMPERATURES (All Models) For engine configurations designated by a suffix for specific installations (see NOTE 12), refer to the appropriate S.O.I. for maximum operating temperatures TURBINE EXHAUST GAS (T495) (INDICATED / SEE NOTE 5) As measured by a harness of nine thermocouples located at the second stage low pressure turbine vane: Takeoff (5 min.)

FUEL AND OIL PRESSURE LIMITS TCDS E29NE PAGE 5 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. NOTE 3.

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. ----END---- ``` ## ADs None name its models. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
