Two personnel from AES Defence recently visited the Royal Army of Oman to assist them with their Condition Based Maintenance program. By using AES’s Trend Analysis program, part of the Machine Care Plus® service, a number of potential issues had been identified prior to the visit. Inspections of the vehicles and discussions with the crews and maintainers confirmed the situation and a maintenance plan was suggested to prevent further occurrences. Continued monitoring will be used to assess the effectiveness of the revised maintenance strategy.
