1. PLANNING INFORMATION A. SB EFFECTIVITY Aircraft affected:
MODEL SN EMBRAER 190 ECJ 19000109, 19000140, 19000159, 19000177, 19000203, 19000225, 19000236, 19000243, 19000261, 19000278, 19000296, 19000307, 19000317, 19000362, 19000438, 19000453, 19000534, 19000559, 19000571, 19000611, 19000632, 19000641, 19000656, 19000683, 19000691, 19000695, 19000705, 19000709, and 19000732, equipped with the affected component.
Affected component:
Refer to paragraph 1.A EFFECTIVITY of ELEB SB190-70240-32-01, in the annex to section 4.
APPENDIX 1, and to paragraph 1.A EFFECTIVITY of Liebherr SB4573A-32-01, in the annex to section
4. APPENDIX 2 of this bulletin.
NOTE: This effectivity list includes the aircraft that originally have the affected component installed.
Since this component is a Line Replaceable Unit (LRU), refer to the fleet maintenance control record and verify if the unit was replaced during routine maintenance.
In-production effectivity:
EMBRAER 190( ) model aircraft SN 19000773 and on, have an equivalent factory-included modification.
B. CONCURRENT REQUIREMENTS None.
C. REASON
(1) HISTORY Some structural parts (life limited items included) used in the MLG of ERJ 190-100/190-200 are common to the MLG used in the ERJ 190-100 ECJ model (Lineage 1000). Although the enditems are not part numbers common to these models, the mentioned common parts may be interchanged during repair or overhaul. Since the operational loads are different for the two models, the adequate life limitation may not be adequately controlled in this scenario. The parts that can not be interchanged must be reidentified for use only on Lineage aircraft.
(2) OBJECTIVE

This Service Bulletin provides instruction to reidentify the MLG side stay assembly and the MLG shock strut assembly, and create dedicated PNs that will prevent the interchange of 190-100/190-200 parts with Lineage parts.
(3) EXPECTED BENEFITS This modification is intended to prevent the incorrect control on the remaining life limit of the affected parts.
(4) REVISION HISTORY None.
