As owner of Ingenieurbüro Lippold I'm offering engineering services (Stress, Certification, Quality Managment) specifically for the aviation industry. Before I was responsible for Stress and Part-21,-25 certification in Switzerland. I was involved in many narrow and wide body aircraft completion projects (Airbus, Boeing, etc.) but also smaller modification projects (Falcon, Bombardier, Gulfstream, etc.). My last position there was Group Leader, Supervisor and Deputy Department Manager of about 30 engineers. After in 2009 I founded my own Engineering Office in Berlin/Germany where I gained additional experience in Quality Management (well familiar with Part-M and JAR 145 and implementation and maintaining of corresponding documents and processes) and also Part-33 certification. I have a personal official license of Femap/NX Nastran 10.3.1 (Finite Elements Methods Software).
