The Maintenance Approved Organization Scheme (MAOS) is a means by which the MoD can assess the competency of organizations wishing to provide continuing airworthiness support services for military registered aircraft - UK MoD
In the civil aerospace environment EASA21 and EASA145 boundaries and activities are well established. However taking that level of thinking and application into the military environment is a relatively new step for some suppliers. Traditionally built around DEFSTAN05-123 design requirements and certified to other non-civil specifications, military airframes and their repairable LRU have been maintained using a variety of bespoke publications derived from OEM source data, and MoD run/controlled repair locations. In a drive to better replicate the quality control and segregation of civil repair methods the recent development and issue of DEFSTAN05-130 (MAOS Military Regulation Pt145) is beginning to have impact at all levels of the military repair supply chain.
Using prior operational knowledge of the civil EASA145 environments, having worked directly with Air France at Paris CDG and Orly, together with 10 yrs experience across several military aircraft Richard Hartley assisted BAE Systems in generating clearer MAOS / DAOS boundaries, increasing understanding and awareness, and also route mapping the flow of Approved Engineering Data both within the company and to/from external parties.
As prime in a MAOS environment, BAE Systems realised the need assess and approve the quality, repair standards and documentation in use by their up stream suppliers. This assessment was undertaken by means of 'Repair Process Verifications', performed both at desktop documentation level and on-site at suppliers premises. The process and methodologies used by BAES were initially drafted by Richard and another BAES employee as a derivative of standard First Article Inspection procedures used on new build equipment. Once trialed and agreed, the RPV process was enacted by small BAE Systems teams supported by Richard who offered first hand FAI and aerospace repair experience to the groups.
The RPV Process won a BAE Systems 2009 Chairman's Award for Transfer of Best Practice
