Extensive aerostructures experience allows AP/ES to provide unique and accurate perspectives on problems where your organization may struggle.

Thomas Mills, Ph.D.

Experimental Methods Specialist

Dr. Mills has over 15 years of experience developing advanced structural integrity methods, with particular emphasis on structural effects of corrosion/fatigue and the interaction of residual stress fields with fatigue. He is an expert failure analyst (including scanning electron and optical microscopy) and has two decades of experience deciphering failures of laboratory and in-service components. Dr. Mills also has extensive hands-on experience with material testing systems as well as mechanical testing and corrosion standards. Prior to his employment at APES, he worked with Aerostructures Technologies, (Melbourne, Australia) for two years as a contractor to the Defence Science & Technology Organisation, Australia in support of their military aircraft fleets. Before that, Dr. Mills worked with the Air Force Research Laboratory in the Air Vehicles Directorate at WPAFB, OH from 1997-2000.

Tom Deiters


Mr. Deiters is an FAA DER Consultant - Structural in Static, Fatigue, and Damage Tolerance. He has over 26 years of specialization in complex stress and life analyses of structural systems in the Aerospace Industry. He has applied strength, durability and damage tolerance principles to transport aircraft, fighter aircraft, and engines, including C-130 Hercules, C-140 Jetstar, C-141 Starlifter, C-5 Galaxy, P-7A, B-707, CN-235, B-737, EMB-120, F-15 Eagle, F-18 Hornet, and F-22 Raptor and has specialized in performing analysis of entire aircraft systems to determine structural integrity. He is a registered Professional Engineer and holds a private pilot's license.

Craig Brooks

President and Chief Engineer

Mr. Brooks has over 35 years experience with Original Equipment Manufacturers and aircraft systems in the development and application of fatigue, fracture mechanics, damage tolerance, and structural integrity. The areas of focus have been establishing engineering applications from theories and incorporating processes to assess the static, durability, and damage tolerance capabilities of structure. He has been involved with establishing the initial applications of fracture mechanics to jet engines and fighter platforms, in the FAA Certification of aircraft under FAR 25.571 part 25, and for the joint specifications for future military air vehicles. This experience base is supported by knowledge of multiple engineering disciplines and an understanding of structural integrity philosophies for the design, manufacturing, and maintenance of aircraft, engines, structures, and other aerospace products. He is author to over 35 papers on subjects related to aircraft, structural integrity, and the engineering associated with them.

Scott Prost-Domasky, D.Sc., P.E.

Finite Element Specialist

Dr. Prost-Domasky has over 19 years experience in the application of advanced engineering concepts including development and applications of finite element methods (FEM/FEA) to structural analyses of linear and nonlinear mechanical systems: aircraft lap joints, composite delamination, orthopedic implants, heart pumps, and blood cells. He has three years experience in aerospace propulsion research and development for two aircraft manufacturers. Dr. Prost-Domasky is a Registered Professional Engineer in the State of Missouri. His recent efforts include analytical models that account for effects of fretting on the degradation of assembled structures. LinkedIn

Kyle Honeycutt

Analytical Methods Specialist

Mr. Honeycutt has over 16 years structural engineering & aerospace structures experience including aircraft stress analysis, fatigue and fracture mechanics, finite element modeling, and engineering software development. He is experienced with numerous hand analysis and design techniques, Microsoft Visual Basic and VBA, Microsoft COM, p- and h-element finite element analysis methods and software, Microsoft Excel-based engineering analysis, C/C++/FORTRAN, and Unix/Linux/Perl scripting. Mr. Honeycutt has implemented OEM standards for numerous structural analysis methods. He is responsible for models and software that enable simulations of cracking in complex configurations, such as cracks growing in integrally stiffened panels and time-based corrosion degradations interacting with cyclic fatigue.
