(b)(4).This report is based on information provided by an engineering evaluation.One powered handle and one adapter was received for evaluation.A visual inspection found no notable conditions.Testing revealed that when no reload is attached, the chamfer on the inner diameter of the load ring rests against the leaf spring, creating a pre-load condition.Under certain assembly/tolerance conditions, this pre-load on the leaf spring can cause it to activate the sulu detect switch when a reload is not attached.The investigation isolated the failure to the size of the load ring chamfer being too small.During investigation, a secondary condition of load ring interference was determined.Should new information become available, the file will be re-opened and the investigation summary amended as appropriate.
