An internal annual review compares orders for Expendable parts against expected usage; if required, a review is conducted between Rolls-Royce and the Customer on the number of LRPs ordered, with remedial actions agreed.

Service Level 1

Updated · Jun 2026

Repairs are managed to a 14-day turnaround time from unit collection.

LRU Shortages

The Overhaul Base will aim to return the same unit to the Engine from which it was removed. If an LRU is not available at the time of Engine kitting, then the Overhaul Base will seek assistance via the Rolls-Royce OBM.

Beyond Economic Repair

If an LRU is deemed beyond economic repair, then the Rolls-Royce OBM will agree replacement options with the Rolls-Royce AST, Customer and the LRU Management team as appropriate.

Best Practice

Ensure all repair order documentation includes complete and accurate information. Missing data can cause delays in processing and may result in additional costs or extended turnaround times.
