Details
The Maintenance Approved Organization Scheme (MAOS) is a means by which the Ministry of Defence (MOD) can assess the competency of organizations wishing to provide continuing airworthiness support services for military registered air systems or air system components.
It is MOD policy that all air domain platform and equipment delivery teams and front line commands (FLCs), where possible, contract for continuing airworthiness activities with organizations that are approved under the MAOS scheme. Details of the approval scheme are published in the Regulatory Article (RA) 4800 series, known as Military Aviation Authority Regulatory Publication part 145.
Please note: there is currently a limited mandated scope for the requirement for MRP part 145 approval. This limited scope is described in RA 1005.
