Cadorath (Booth 3228) has completed initial deliveries of repaired and overhauled Rolls-Royce M250 engine series IV outer combustion cases. The overhaul includes repairs to the fuel boss and replacement of the existing wire mesh patches with reinforced dual mesh patches.

It developed the repair following a year of testing alternative braze alloys, surface preparation procedures, and fatigue after Rolls-Royce issued a mandatory commercial bulletin (CEB) with regard to the affected outer combustion cases (P/N 23030911) on Oct. 28, 2018, at engine overhaul or 2,000-hour inspection. The repair is performed at Cadorath’s Broussard, Louisana facility.  

“Since the release of the CEB, there has been considerable urgency for this repair,” said Cadorath director of operations Larry Barkley. “The completion of this project reaffirms our commitment to the Rolls-Royce FIRST Network, as well as all M250 operators and maintainers,” he said. 

Separately, this week at Heli-Expo 2020 Cadorath unit Meridian Helicopters (Static 15) of Lafayette, Louisana, is displaying a Southern Utah University (SUU) Bell 206L4 it recently overhauled and modified with components including Garmin avionics with ADS-B Out, NVG compatibility, Bose headsets, new paint and interior, new windows, Onboard cargo hook and load cell, engine particle separator, and dual aircraft controls.

SUU uses refurbished aircraft such as the 206L4 for advanced helicopter training. The university also provides its 206L4 and pilots to the Iron County, Utah sheriff’s department for search and law enforcement missions.
