Automotive Fasteners Expert Witness




Expert Witness No.2219

Professional Summary

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 30 years, that system (Monogram Aerospace Fasteners' Composi-Lok©) 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. Recent fastener development activities include blind bolt, blind temporary clamp and shear pin development for robotic assembly of aircraft structures.
