Griffith Park Helicopter Incident bending losses www.baumhedlundlaw.com This animation shows the sections of the tail rotor yoke. The cross sections are reduced in thickness to allow flexion (bending). The yoke is designed to bend with the parameters set, without changing its strength. When a force strikes the tail rotor big enough to get them to deliver the tolerance design can be "overloaded" static damage, loss of compressive residual stress and stress generated resultsresulting in fatigue fracture. Static overloads occur when the tail rotor is stopped, not when a helicopter flight. static overload can be due to improper use of land (eg the tail rotor blade as a handle to be caused to move the helicopter), collision with a vehicle, improper storage, while the yoke was removed by helicopter , and gusts of wind or jet blast. The animation shows the bending of the bracket 1), in its design tolerance and 2) outside of its design tolerance. TreeHedlund has prepared this animation as one of many, as evidence in product testing in 2006 in Los Angeles Superior Court against Bell Helicopter Textron, Inc. and Bell Technical Services are displayed, Inc. The study of Baum, Hedlund, Goldman was Aristea & carried. History: A Bell Model 205a-1 helicopter, owned and operated by the LAFD crashed in Griffith Park During an Airlift Rescue in Los Angeles March 23, 1998. The airlift helicopter was injured by a childa car ...
