Coatings
Heating Treatment
Non Destructive Testing
Surface Enhancement
Welding

Centre of Excellence (CoE)

Is a significant element of the Rolls-Royce (RR) 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 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 network aircraft maintenance centres and independent overhaul facilities repairing Rolls-Royce aero engines.

HAESL has 9 “Gold” rated CoEs, which is the highest number across the Rolls-Royce MRO network:
