For operators with aircraft delivered and still fitted with ELAC Hardware A or A’ without data-loading capability activated as per Mod. No. 36999P9999: . Removing ELAC Hardware A or A’ Standard L84 PN 3945122609 or PN 3945123609, . Installing ELAC B-dl Standard L97+ PN 3945129100 with operational software PN 3945129109 loaded. For the status of operators with regard to the installed ELAC on aircraft, refer to the Configuration Definition paragraph. The purpose of ELAC B Standard L97+ is to propose the new following functions: - addition of one new elementary Angle Of Attack (AOA) monitoring (based on delta Nz associated with delta Alfa). This monitoring is based on vertical load factor variations always preceded by AOA variation, - increase of Vc, M, TAS monitoring thresholds when aircraft is flying beyond operational AOA, moreover the threshold monitoring becomes f (AOA and estimated sideslip), - use MAN PITCH TRIM display on Primary Flight Display (PFD) during first phase of unusual flight control law, - modification to avoid Load Alleviation Function (LAF) activation (on aircraft fitted with sharklets) following side stick release, - A320 aircraft fitted with sharklets: inhibition of anti-pitch up law used at high Mach and high AOA when speedbrakes are extended. Main load content of ELAC B-dl Standard L97+ in comparison to ELAC A/A’ Standard L84 (last certified standard): NOTE: ELAC A/A’ L84 is equivalent to ELAC B L93.

SERVICE BULLETIN SUMMARY The improvements introduced by ELAC B-dl Standard L94: - Manoeuvre Load Alleviation/Gust Load Alleviation (MLA/GLA) function, also called Load Alleviation Function (LAF). - This function is activated by pin programming (Mod. No. 39286P11140) has to be requested by the RFC/RMO procedure. - This new MLA/GLA function is designed on Single Aisle (SA) in order to be able to justify the load analysis required for: . A319CJ MTOW increase 1 ton: the aim is to reduce the wing root bending moment by about 2 percent, . A320 WV015 forward CG extension: the aim is to reduce the wing root bending moment by about 2.5 percent and turbulence discrete gust by about 2 percent. - Improvement of the flight control laws with regards to the transition flare law to ground law. The modification consists in vanishing faster the integrated part of the elevator in order to avoid hard landing or tail strike, in case of unusual landing due to strong nose-up side stick deflection (-10 degrees), maintained 5 seconds after touch down. The improvements introduced by ELAC B-dl Standard L96: - Sharklets capability, - No reversion to alternate law after loss of yaw damper function: normal law holding while alternate display on A320, A321 and A318 aircraft fitted with sharklets, - A319 take off rotation improvement, - Aileron up deflection at ground spoiler extension becomes basic function, - Modification of the transition logic from flight lateral normal control law to ground normal law, - Modification to avoid on ground simultaneous pressurization on both servocontrol of each elevator, - Modification of path angle treatment in order to avoid direct law reversion following 3 Air Data Reference (ADR) loss, - Modification of the consistency monitoring between the pitch priority discrete output towards SECs and the equivalent information sent on the COM/MON ELAC ARINC bus, in order to solve some ELAC PITCH FAULT issue associated with the maintenance message CHECK PITCH CHANGE OVER OF ELAC, - Correction of ELAC FAULT: regression introduced with not loadable ELAC B standard 94 and loadable ELAC B standards 91, 93, 94 following: . Electrical transfer around 3 seconds with three hydraulic pressure low, . Aircraft electrical power up with one hydraulic pressure switch detected high pressure within only one ELAC unit.

SERVICE BULLETIN
For operators with aircraft delivered and still fitted with ELAC Hardware A or A’ without data-loading capability activated as per Mod. No. 36999P9999: . Removing ELAC Hardware A or A’ Standard L84 PN 3945122609 or PN 3945123609, . Installing ELAC B-dl Standard L97+ PN 3945129100 with operational software PN 3945129109 loaded. For the status of operators with regard to the installed ELAC on aircraft, refer to the Configuration Definition paragraph. (3) Advantages The purpose of ELAC B Standard L97+ is to propose the new following functions: - addition of one new elementary Angle Of Attack (AOA) monitoring (based on delta Nz associated with delta Alfa). This monitoring is based on vertical load factor variations always preceded by AOA variation, - increase of Vc, M, TAS monitoring thresholds when aircraft is flying beyond operational AOA, moreover the threshold monitoring becomes f (AOA and estimated sideslip), - use MAN PITCH TRIM display on Primary Flight Display (PFD) during first phase of unusual flight control law, - modification to avoid Load Alleviation Function (LAF) activation (on aircraft fitted with sharklets) following side stick release, - A320 aircraft fitted with sharklets: inhibition of anti-pitch up law used at high Mach and high AOA when speedbrakes are extended. Main load content of ELAC B-dl Standard L97+ in comparison to ELAC A/A’ Standard L84 (last certified standard): NOTE: ELAC A/A’ L84 is equivalent to ELAC B L93. The improvements introduced by ELAC B-dl Standard L94: - Manoeuvre Load Alleviation/Gust Load Alleviation (MLA/GLA) function, also called Load Alleviation Function (LAF). - This function is activated by pin programming (Mod. No. 39286P11140) has to be requested by the RFC/RMO procedure. - This new MLA/GLA function is designed on Single Aisle (SA) in order to be able to justify the load analysis required for: . A319CJ MTOW increase 1 ton: the aim is to reduce the wing root bending moment by about 2 percent, . A320 WV015 forward CG extension: the aim is to reduce the wing root bending moment by about 2.5 percent and turbulence discrete gust by about 2 percent.

- Improvement of the flight control laws with regards to the transition flare law to ground law. The modification consists in vanishing faster the integrated part of the elevator in order to avoid hard landing or tail strike, in case of unusual landing due to strong nose-up side stick deflection (-10 degrees), maintained 5 seconds after touch down. The improvements introduced by ELAC B-dl Standard L96: - Sharklets capability, - No reversion to alternate law after loss of yaw damper function: normal law holding while alternate display on A320, A321 and A318 aircraft fitted with sharklets, - A319 take off rotation improvement, - Aileron up deflection at ground spoiler extension becomes basic function, - Modification of the transition logic from flight lateral normal control law to ground normal law, - Modification to avoid on ground simultaneous pressurization on both servocontrol of each elevator, - Modification of path angle treatment in order to avoid direct law reversion following 3 Air Data Reference (ADR) loss, - Modification of the consistency monitoring between the pitch priority discrete output towards SECs and the equivalent information sent on the COM/MON ELAC ARINC bus, in order to solve some ELAC PITCH FAULT issue associated with the maintenance message CHECK PITCH CHANGE OVER OF ELAC, - Correction of ELAC FAULT: regression introduced with not loadable ELAC B standard 94 and loadable ELAC B standards 91, 93, 94 following: . Electrical transfer around 3 seconds with three hydraulic pressure low, . Aircraft electrical power up with one hydraulic pressure switch detected high pressure within only one ELAC unit. . Modification of transition from flight to ground lateral law. The improvements introduced by ELAC B-dl Standard L97: - Addition of two elementary Radio Altimeter (RA) monitoring in order to be able to detect more RA failure, - Adaptation of autopilot (AP) mode disconnection logic (depending on radio altimeter and angle of attack) to increase AP disconnection logic, - Tuning of ADR parameter treatment and monitoring, - Addition of one new condition based on Calibrated Air Speed (CAS) to limit THS up deflection, DATE: Mar 17/15 SERVICE BULLETIN No.: A320-27-1243 REVISION No.: 00 - Mar 17/15 Page: 35 5

3. ACCOMPLISHMENT INSTRUCTIONS Task 271243-831-801-001 - Modification by Uploading of the two ELACs (FINs 2CE1 and 2CE2) in accordance with VSB on Bench WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES. CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS: - PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC. AS NECESSARY ON WIRING AND COMPONENTS. - REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND OTHER CONTAMINATION. THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION AND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION. IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00. NOTE: The accomplishment instructions of this Service Bulletin include procedures given in other documents or in other sections of the Service Bulletin. When the words "refer to" are used and the operator has a procedure accepted by the local authority he belongs to, the accepted alternative procedure can be used. When the words "in accordance with" are used then the given procedure must be followed. NOTE: The access and close-up instructions, not comprising return to service tests, in this Service Bulletin do not constitute or affect the technical intent of the Service Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the Service Bulletin is met within the set parameters. NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms. Refer to paragraph 1.J., References, for the definition of acronyms. NOTE: This Service Bulletin is classified mandatory or expected to be classified mandatory by an Airworthiness Directive (AD). The paragraphs 3.C. and 3.D. in these accomplishment instructions are Required for Compliance (RC) and must be done to comply with the AD. Other paragraphs are recommended and may be deviated from, done as part of other actions or done with accepted methods different from those given in the Service Bulletin, as long as the RC paragraphs can be done and the aircraft can be put back into a serviceable condition.

NOTE: The accomplishment instructions of this Service Bulletin include procedures given in other documents or in other sections of the Service Bulletin. When the words "refer to" are used and the operator has a procedure accepted by the local authority he belongs to, the accepted alternative procedure can be used. When the words "in accordance with" are used then the given procedure must be followed. NOTE: The access and close-up instructions, not comprising return to service tests, in this Service Bulletin do not constitute or affect the technical intent of the Service Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the Service Bulletin is met within the set parameters. NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms. Refer to paragraph 1.J., References, for the definition of acronyms. NOTE: This Service Bulletin is classified mandatory or expected to be classified mandatory by an Airworthiness Directive (AD). The paragraphs 3.C. and 3.D. in these accomplishment instructions are Required for Compliance (RC) and must be done to comply with the AD.

Task 271243-831-803-001 - Modification by Replacement of the two ELACs (FINs 2CE1 and 2CE2) on Aircraft **CONF ALL WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES. CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS: - PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC. AS NECESSARY ON WIRING AND COMPONENTS. - REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND OTHER CONTAMINATION. THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION AND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION. IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00. NOTE: The accomplishment instructions of this Service Bulletin include procedures given in other documents or in other sections of the Service Bulletin. When the words "refer to" are used and the operator has a procedure accepted by the local authority he belongs to, the accepted alternative procedure can be used. When the words "in accordance with" are used then the given procedure must be followed. NOTE: The access and close-up instructions, not comprising return to service tests, in this Service Bulletin do not constitute or affect the technical intent of the Service Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the Service Bulletin is met within the set parameters. NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms. Refer to paragraph 1.J., References, for the definition of acronyms. NOTE: This Service Bulletin is classified mandatory or expected to be classified mandatory by an Airworthiness Directive (AD). The paragraphs 3.C. and 3.D. in these accomplishment instructions are Required for Compliance (RC) and must be done to comply with the AD. Other paragraphs are recommended and may be deviated from, done as part of other actions or done with accepted methods different from those given in the Service Bulletin, as long as the RC paragraphs can be done and the aircraft can be put back into a serviceable condition.
