05 - KC-46 TCI Schedule (Attachment 5).xlsx

This file is a Time Change Interval (TCI) Schedule for KC-46 Landing Gear components, establishing the programmed maintenance and overhaul timeline for all depot-level repairable items. The schedule spans from fiscal year 2028 through 2038, with 139 discrete maintenance events identified across the contract period. Each TCI entry includes a component identification number (ranging from 005C to 139), a scheduled check/maintenance due date, the fiscal year in which the work must be completed, and a final adjusted induction date that precedes the due date. The schedule is organized in a matrix format showing monthly distribution of workload across the 11-year performance period, with total monthly requirements varying from 9 to 23 maintenance actions per month, totaling 287 individual TCI events.

The schedule establishes the operational framework for the KC-46 Landing Gear Performance Based Logistics (PBL) contract (SPRHA1-26-R-4646), which requires remanufacture and overhaul support for all landing gear depot-level repairables including shipsets and field-level replaceable subcomponents. The earliest scheduled maintenance action begins in September 2028 (component 023), with subsequent events distributed throughout the period, with the final scheduled maintenance completion in January 2038 (component 139). The document notes that the TCI schedule is updated annually and subject to change, providing flexibility for operational adjustments while maintaining the established maintenance cadence necessary to support KC-46 aircraft availability and mission requirements.
