Expert Witness No.2219

California

Professional Summary

This Expert provides new product development consulting for the Aerospace Fastener and Aircraft Interiors industries, as well as litigation consulting in the areas of mechanisms, latches and fasteners.

Before retiring as an aerospace industry executive in 2005, Expert co-invented and led the development of the post-9/11 secure (terrorist-proof) cockpit door decompression latches now installed on half the world’s fleet of aircraft. Previously Expert invented and commercialized the first viable blind fastening system for laminated composites. After 24 years, that system remains one of the most-used structural blind fasteners for composite airframe assembly.  Recent litigation consulting projects have included aircraft engine cylinder head bolt failure analysis, aircraft hanger wind-induced anchorage loss, and motor home retractable bunk mechanism analysis.
