APU LLP Hours and Cycles Management Application
APU utilisation, LLP register and data reconciliation with a complete audit history.
LLP means Life Limited Part. Some APU components have approved operating life limits, so accurate hours and cycles records are essential for maintenance planning and airworthiness management. This application covers APU utilisation, an LLP register, and reconciliation of utilisation data between authorised aircraft data sources and maintenance systems.

The application does not change official LLP records. Approved corrections are recorded here and applied to the maintenance system through the operator's approved process.

Key Benefits
Why LLP & Utilisation
Discrepancies caught
Differences between data sources, resets and gaps are flagged for investigation.
Original data preserved
Source records are never overwritten; corrections are recorded and approved.
Planning with confidence
Remaining life and forecasts in one register with a full audit trail.
How It Works
Workflow
Example
An aircraft system reports one APU cycle count while the maintenance database contains another. The application compares the records, flags the discrepancy for investigation and preserves both values until authorised personnel record and approve a correction.
