News & Events-Frazer-nash completes Europe-wide harmonised military airworthiness criteria

Engineering consultancy Frazer-Nash, working with Marshall Aerospace and Defence Group, has successfully delivered the European Military Airworthiness Certification Criteria (EMACC) handbook as part of its contract with the European Defence Agency (EDA). 

The EMACC handbook includes fully harmonised airworthiness certification criteria and cross references existing military and civil standards used by Member states. It is a guidebook for use to help define the certification basis for military airworthiness approval in order to achieve type certification.

The EMACC handbook supports the Military Airworthiness Authorities (MAWA) forum and its related task forces aim of developing European Military Airworthiness Requirements and harmonised supporting documents. These documents will help create a military regulatory regime that will facilitate the acceptance of aircraft, designed and manufactured in one state, as being deemed airworthy by another state. This will reduce duplication across countries, cut initial aircraft procurement costs and, potentially, through life costs as well.

Martin Soltau, Business Manager for Frazer-Nash, said:"We are delighted to have supported the EDA in this challenging initiative. Certification is a very significant cost for any military aircraft programme. With the increasing need for European nations to collaborate on both aircraft development programmes and military operations, harmonisation of airworthiness requirements will be a crucial step in making such collaborative ventures more feasible and cost-effective."

Frazer-Nash looked at all aspects of airworthiness certification, including flight dynamics, avionics and propulsion. The approach taken also ensured that the harmonised certification criteria allowed national certifying authorities within Europe the latitude to interpret the most appropriate approach to achieve compliance.

This follows Frazer-Nash's successful feasibility study conducted in 2010 which proved the viability of the harmonisation approach, produced harmonised certification criteria relating to structural integrity and provided the framework for the EMACC handbook.

Tim Andrews, Project Manager for Frazer-Nash commented:"The benefits of a common set of harmonised airworthiness criteria and requirements across Europe are clear - in essence it could mean that an aircraft type certified for use in one member state could automatically be certified for use in another, giving real cost and time advantages.

"It was not a simple matter of transposing the harmonised system currently used in the civil world into the military environment - aircraft used for military missions may be exposed to a higher level of risk, or are used for a wider range of missions when compared to a civilian aircraft. The EMACC handbook will be a guidance document which can help to define and agree airworthiness certification requirements for all manned and unmanned, fixed and rotary wing air vehicle systems."

The EMACC handbook has now been issued to the Military Airworthiness Authorities Forum for formal European consideration.
