The aircraft manufacturer, working with the LOH Project Manager, presented an Engineering Change Proposal to increase the parameters of the main-rotor blade tolerances for OH-6A helicopters. On 12 August 1968 the US Army Test and Evaluation Command directed the US Army Aviation Test Board (USAAVNTBD) to conduct a product-improvement test of OH-6A rotor blades with increased twist and contour thickness tolerances.
