Consulting for Aircraft System Development and Certification

We are seasoned experts with over 25 years of experience in aircraft development and certificaton to help you save costs and get your project approved faster.

✈️ EASA Independent External Expert for Aircraft Design

Our time is characterised by tremendous rates of innovations, coming along with a significant increase in product complexity.

Complexity requires a dedicated level of care even more in safety critical applications.

Our competences are to assist you in balancing your products adequately between customer needs and desires, safety, a manageable level of complexity, and innovation.

These are the key aspects and the prerequisites for the successful and long term establishment of your products on the market.

With over 25 years of experience on certification projects for Large Aircraft (CS-25) and Turbojet Engines (CS-E), let us help you develop and establish realistic, adequate and effective strategies and associated processes for the development of highly integrated, complex and safety critical aviation products and systems.

About Certification Office

” Safety is our motivation. Your success is the objective. “

We are a team of engineers who have gained their experiences over many years and over many projects in the aviation business on the subject of development of complex and safety critical systems on large transport aircraft and turbojet engines.

Our expertise is in the areas of project management, certification, design, testing and safety assessments of those products.

Our achievements are the development and certification of the TP400D6 Engine powering the Airbus A400M aircraft, the Rolls-Royce BR700-725A1-12 engine powering the Gulfstream G650 business jet aircraft and BR700-710D5-21 engine (The Pearl Engine) powering the Bombardier Global Express 6500 business jet aircraft.

We are actively involved in the development and EASA rulemaking tasks for future Hydrogen Fuel Cell / Electric powered Aircraft Technologies and UAV‘s.

The Rationale

With the increase in complexity and concurrent approaching of physical and technical limits on new aircraft generations, small residual design errors are becoming even less tolerable from the safety and the performance perspective compared to previously developed generations of aircraft.

Avoidance, detection and elimination of design and implementation errors are even more important. New development and safety assessment techniques and philosophies are required taking this matter of facts into consideration. ICAO Safety Manual directly calls the search for the so called „Safety Space“, the limits between prevention of accidents/unsafe conditions and prevention of bankruptcy, the „Management Dilemma“.

We gained considerable experiences over recent projects in aviation and safety engineering to assist you to dissolve this dilemma and-to balance your projects between those limits to ensure you will achieve your objectives in a safe, cost effective and timely manner.

Showing of compliance with CS-23, CS-25, CS-E, especially CS-2X.1309 and CS-E 510 makes the introduction of the principles of ARP4754A, ARP4761 essential. It will lead to:

  • get aircraft and system complexity under control
  • satisfy your project and customer requirements
