Patria has a key role in flight safety

Patria oversees that the design work and used methods and processes are compliant with applicable flight regulation requirements. This role is obtained through the MDOA/DOA certificates which enables proper responsibility for flight safety.



designs and analyses minor and major modifications and repairs for military and civil aircraft partners to upgrade and enhance A/C performance and to reach their targeted & estimated life cycle. The work is mainly done for fixed and rotary-wing aircrafts. Design work is conducted also in the tools and testing equipment front.


Systems engineering and technical support

provides manufacturing and maintenance technical support services wherever and whenever it is needed. This includes maintenance development tasks, tools & testing equipment design and content for service manuals related to frame, engine and equipment maintenance.


Technical publications services

are responsible for the publication, distribution and maintenance of Patria's management system instructions, such as procedures, technical instructions, handbooks and forms. They are also responsible for maintaining, distribution and updating of product type-specific documentation, such as technical manuals, drawings and other fleet-specific data material provided by the Finnish Air Force to Patria, to the extent agreed in customer contracts.
