HAESL has a broad range of specialised component repair capabilities, allowing it to offer customers cost effective alternatives to outright replacement.  .  We are often able to rebuild parts back to a fully restored condition so that they have the same integrity and durability as new parts.  .   Supporting arisings both internal and from the aero engine repair network worldwide, we have a 92% in-house core engine component repair capability.
The Centre of Excellence (CoE) Programme is a significant element of the Rolls-Royce Aero Repair and Overhaul (AR&O) global strategy in establishing a world-class component repair business network for key components.

HAESL’s CoEs for the repair of Honeycomb and Bearing Support were the first worldwide to achieve the top level ‘Gold’ accreditation by Rolls-Royce in 2005.  .  The CoEs for Turbine Blade, Fan Blade and Seal Fin all achieved the award of the gold status in 2006, 2007 and 2012 respectively. In 2013, four other CoEs received ‘Gold’ accreditation, namely Engine Mount, Compressor Case, Vane and Variable Inlet Guide Vane.

The success of the CoE demonstrates that HAESL is one of the ‘World-Class’ repairers within the Rolls Royce component repair global network and committed to developing a component repair business to meet the needs for both AR&O and independent overhaul facilities repairing Rolls Royce aero engines.
