Boeing and GE Aviation said they have developed a method to implement condition-based maintenance systems on aircraft, which the companies said will make it practical for embedded health monitoring of aircraft systems. The method, called the Open System Architecture for Condition-Based Maintenance (OSA-CBM), will become an industry standard with the signing of an agreement by the two companies to grant rights for its use to the Machinery Information Management Open Systems Alliance (MIMOSA) organization. "This technology demonstrates a major step forward in condition-based maintenance for an entire aircraft,"s aid John Armendarez, president of Avionics for GE Aviation. Project managers implementing condition-based maintenance systems must integrate a wide variety of software and hardware components, each one developed to monitor a single supplier's system such as an engine, hydraulic or braking system. The companies say OSA-CBM simplifies this process by specifying a standard architecture and framework to implement condition-based maintenance systems. This standard defines the binary form to implement the open systems architecture for condition-based maintenance.
