Chief Scientific and Technical Advisor for Engine System Dynamics and Safety

Dr. Queitzsch has over 20 years experience in rotating machinery dynamics primarily focused on aviation propulsion gas turbine engines and accessories.

Prior to joining the FAA, Dr. Queitzsch was a Boeing Propulsion Technical Fellow specializing in rotating machinery dynamics analysis, testing, failure investigations, and new product design reviews. These reviews addressed issues associated with rotor stability, transient dynamics, forced response, rotor integrity, and high speed bearing and seal failures.

At Boeing, most of Dr. Queitzsch's work was in support of the main propulsion gas turbine engines and auxiliary power units installed on all current Boeing Commercial Airplane models, several military applications, and consulting for several small company turbo-generator programs.

Since joining the FAA in November 2003, Dr. Queitzsch has been involved with engine certification and field service issue investigations for large transport, regional jet, and general aviation engine programs and is participating in the FAA’s engine catastrophic failure research and development programs.

Dr. Queitzsch has taught in Propulsion System Short Courses at Boeing and Purdue University, and is published in the areas of rolling element bearings, rotor dynamics, and engine vibration effects on cabin noise and vibration.

Member, professional organizations and societies:

• American Society of Mechanical Engineers (ASME)
• International Society of Air Safety Investigators (ISASI)
• Society of Tribologists and Lubrication Engineers (STLE)
• Vibration Institute

Industry and government awards: Boeing Invention Award for a new Mechanical Fuel Control Governor concept.

Academic achievements:

• Ph.D. in Mechanical Engineering from the University of Virginia
• ME and BS in Civil Engineering from the University of Virginia

Also, Dr. Queitzsch holds a certificate in Gas Turbine Accident Investigation from the Southern California Safety Institute.
