This is a CFM56-3 Life Limited Parts List for a jet engine with serial number 720189. The document provides a comprehensive inventory of critical rotating and structural components subject to operational cycle limitations, dated March 17, 2026, and certified by Rob Hankins.

The list identifies 18 life-limited parts across multiple engine sections including the booster spool, fan disk, fan shaft assembly, high-pressure compressor (HPC) components, high-pressure turbine (HPT) components, and low-pressure turbine (LPT) components. Each part is tracked with specific identifiers: part number (P/N), serial number (S/N), time since new (TSN) of 78,593.1 hours, and cycles since new (CSN) of 64,406 cycles. The document establishes individual cycle limits for three operational categories (A, B, and C) for each component, ranging from 15,000 to 30,000 cycles depending on the part and operational category. Remaining service life varies by component and category, with some parts such as the booster spool and fan shaft assembly having 16,863 remaining cycles across all categories, while others such as the HPC rear air seal and HPT front air seal have more restricted remaining cycles. This inventory document serves as a critical maintenance record for tracking component airworthiness and scheduling overhaul or replacement activities to ensure compliance with manufacturer-imposed life limits.
