General The Safe Life Component discard tasks for the Embraer-190-100 ECJ are classified as airworthiness limitations and are mandatory actions derived from certification fatigue tests or special request from a given Regulatory Authority, due to incomplete endurance testing results. The list of Service Life Limits for rotating parts on the General Electric CF34–10E Engine is in the Airworthiness Limitations Section of the General Electric Engine Shop Manual GEK11208. The list of parts with life limits for the Landing Gear are listed in Table 1. Those limits are preliminary based on the current results of the fatigue test and will be revised according to new test results. Table 1 on item 2 - "Life limited Parts” are applicable to all aircraft. Special requirements of a given Regulatory Authority will be included in additional and dedicated tables. The LLI are a result of the Engineering Certification analysis and have been approved by ANAC. All LLI listed in Appendix A Part 4 are part of the Aircraft Airworthiness Limitation, as mentioned in the TCDS. 2. Life Limited Parts The landing gear life limits are listed in Table 1 – Landing Gear Life Limited Parts. For procurable items, please refer to IPC (Illustrated Parts Catalog) or the appropriate LG log card.
